Question 2: Scientists predict that all fertilizers used in agricultural factories in the future will be liquid fertilizers, and all kinds of existing biological fertilizers are based on organic matter, and then mixed with microbial agents and inorganic fertilizers. In order to improve this universal and traditional situation, bio-fertilizer products go far beyond the existing concepts. It will be expanded to not only provide crop nutrition, but also improve the soil; At the same time, it is necessary to disinfect the soil, that is, use organisms (mainly microorganisms) to decompose and eliminate pesticides (pesticides and fungicides), herbicides and petrochemical pollutants in the soil, and at the same time play a role in repairing the soil. Biological fertilizer in a narrow sense refers to microbial (bacterial) fertilizer, referred to as bacterial fertilizer, also known as microbial inoculum. It is made of microorganisms with special effects through fermentation (artificial culture) and contains a large number of beneficial microorganisms. After being applied to the soil, it can not only fix nitrogen in the air, activate nutrients in the soil and improve the nutritional environment of plants, but also produce active substances and specific microbial products needed for plant growth in the process of microbial life activities. Biological fertilizer in a broad sense refers to biological agents that are made by biotechnology and have specific fertilizer effects on crops (or have fertilizer effects and * * * effects). Its effective components can be specific living organisms, metabolites of organisms or matrix transformants. This organism can be microorganisms, animal and plant tissues and cells. Biological fertilizer, like chemical fertilizer and organic fertilizer, is an important fertilizer source in agricultural production. In recent years, the unreasonable application of chemical fertilizers and chemical pesticides not only consumes a lot of non-renewable resources, but also destroys the soil structure, pollutes the quality of agricultural products and the environment, and affects the healthy survival of human beings. Therefore, judging from the development trend of green agriculture and ecological agriculture advocated by modern agricultural production, pollution-free biological fertilizers that do not pollute the environment will certainly play an important role in future agricultural production.
Question 3: How to identify the quality of liquid fertilizers According to industry standards, there are six kinds of liquid fertilizers on the market at present, including amino acids, humic acids, trace elements, medium elements, macro elements and organic water-soluble fertilizers. Although the types are different, the quality is similar, mainly from the following aspects: seeing, weighing, smelling, freezing and measuring.
Liquid fertilizer products in good physical condition are clear and transparent, clean and free of impurities. Although the black solution of amino acids, humic acids and other suspended fertilizers is opaque, there is no precipitation at the bottom of the bottle after careful observation, and there may be many solid insolubles in the bottle of inferior products.
Weighing products Each product has the minimum requirement of nutrient content. The unit of each nutrient element in liquid fertilizer is gram/liter. The larger the numerical value, the heavier the liquid product with the same volume, and the greater its specific gravity. Therefore, the specific gravity is an important index to measure the quality of liquid fertilizer products. A good product may not have a large proportion, but a small proportion is definitely not enough. The proportion of qualified amino acids, humic acid and organic water-soluble fertilizer is generally above 1.25, that is, the weight of 1 liter of liquid fertilizer is above 1.25 kg, and the proportion of large, medium and trace elements is mostly above 1.35.
Products that smell good have no obvious smell, and some products have a slight ammonia smell under weak acid or weak alkali conditions. The pH value with strong ammonia flavor is not well controlled. Those with special fragrance are generally used to cover up some odors, and those with pungent odor are generally added with substances that should not be added.
Products with good freezing stability will not crystallize in layers even if they are frozen in the refrigerator for 24 hours, and those products with layered crystallization are usually not well-selected raw materials and well-controlled production processes.
Question 4: What is the liquid fertilizer for potted plants? Just soak the compound fertilizer in water.
Question 5: What are clear liquid fertilizer and suspended fertilizer? This question initiated in 2008 has never been answered! In fact, it is estimated that in recent years, no matter using Baidu, 360 or other search, there are few introductions about this kind of clear liquid fertilizer and suspended fertilizer, that is, the related industries have really developed rapidly in the past two years, and even the domain names such as green leaf fertilizer and clear liquid fertilizer seem to have just been registered. This may also reflect the slow development of liquid fertilizer in China from one side, and also clearly reflect that there is still a big gap between China's agricultural water and fertilizer utilization mode and the developed countries in the world!
Among the flowers, birds, insects and fish, it is estimated that you might have to check the professional fertilizer problems of cash crops or flower planting at that time, right? In fact, I think it should be said that this may be a big problem related to the utilization of water resources in the world, the utilization of chemical fertilizers in modern planting, healthy, green and pollution-free food, and the development of agriculture, farmers and rural economy in China.
Anyway, clear liquid fertilizer and suspension fertilizer are both liquid fertilizers, also called fluid fertilizers, which should be called clear liquid fertilizer and suspension fertilizer.
Clear liquid fertilizer refers to dissolving all nutrients needed for crop growth in water to form clear liquid without precipitation.
The nutrients in the suspended fertilizer are not completely dissolved, but the nutrients needed by plants are suspended in the liquid by adding additives.
Two kinds of liquid fertilizers have their own advantages and characteristics in production practice. All the nutrients in clear liquid fertilizer are dissolved in the liquid phase to form a uniform liquid, which can give play to the advantages that solid fertilizer can't do in mechanical fertilization.
In the past, due to technical factors, the nutrient content of clear liquid fertilizer in China was relatively low and the cost of liquid transportation was high, so the development was slow. However, with the development of technology, the leading brands in the market have launched many products with 50% content in the past two years, which has significantly opened up the development space. ....

Question 7: What is the development trend of chemical fertilizer? Due to the seasonal use of products and the close relationship with agriculture, China's fertilizer industry has the characteristics of periodicity and strong policy. At present, the overall development of fertilizer industry is facing difficulties. The development trends of chemical fertilizer industry in the early period of "Twelfth Five-Year Plan" include:
The overall demand growth of DD is limited.
The consumption of nitrogen and phosphorus fertilizer in China has entered a stable platform period of supply and demand, and the factors that increase and inhibit the demand for fertilizer interact, so the demand for fertilizer will grow slowly in the future.
Factors of expanding fertilizer demand
First of all, we need to ensure a stable food supply in the future. By 2030, the population of China will reach1600 million, and the total grain output should be 640 million tons based on 400 kilograms of grain per capita. Under the condition of the same grain planting area, the grain output per unit area needs to be increased from the current 4300 kg per hectare to 5600 kg per hectare, an increase of about 25%. In the future, it is difficult to increase the output by chemical fertilizer alone, but the chemical fertilizer industry, which contributes about 40% to the grain output, undoubtedly plays an important role in ensuring the food supply security. This is also the rigid demand for chemical fertilizers.
The second is the purchasing power support after the increase of farmers' income. Since 20 1 1, the state has continuously implemented various policies to benefit farmers, and farmers' planting income has been continuously improved, which is conducive to mobilizing farmers' enthusiasm for planting and increasing fertilizer input. At the same time, the price increase of agricultural products plays an important supporting role in the demand of chemical fertilizer market. During the "Twelfth Five-Year Plan" period, the prices of agricultural products will maintain a steady upward trend, providing a guarantee for increasing fertilizer input.
Third, the price of chemical fertilizer in the international market remains high. According to the latest report of the International Fertilizer Industry Association, the global fertilizer consumption is expected to increase by 4.7% in the 20 10-20 1 1 planting season due to the double impact of rising crop prices and economic recovery. By the 20 1 1 ~ 20 12 planting season, the global fertilizer demand will return to the level before the financial crisis. It is estimated that 20 1 1 international fertilizer prices will be at a high level. Although China's fertilizer export policy is strictly controlled, international fertilizer prices still have a certain impact on the domestic market, especially during the off-season of tariffs. If the international fertilizer price remains high, it will maintain a certain fertilizer export and support market demand.
Factors inhibiting demand
First, from the perspective of demand growth, the apparent annual consumption of nitrogen fertilizer in China was stable at about 33 million tons (pure quantity) in the first three years from 2005 to 2009, and increased to 36 million tons in 2009; From 2005 to 2009, the consumption of phosphate fertilizer was stable at110.5 million ~1250,000 tons (pure quantity). However, from 2005 to 20 12, the domestic grain has been stable and high-yield for seven consecutive years, which shows that the utilization efficiency of chemical fertilizers in China is gradually improving, and also shows that the domestic demand for chemical fertilizers has entered a platform period.
Second, from the perspective of improving the utilization rate of chemical fertilizers, China feeds 22% of the world's population with 7% of the world's land, but it also consumes nearly 35% of the world's chemical fertilizers. This shows that the use and density of chemical fertilizer per unit agricultural area in China has reached a high level, and the efficiency of increasing chemical fertilizer production is limited, which directly limits the new space for the expansion of chemical fertilizer demand.
Third, from the progress of fertilization methods, scientific fertilization has inhibited the excessive growth of fertilizer consumption. The development history of chemical fertilizer industry in developed countries in Europe and America shows that the total amount of chemical fertilizer application is gradually decreasing after reaching a certain scale. With the deepening of China's agricultural reform and the improvement of agricultural science and technology, China's fertilizer industry will also develop a series of similar changes, especially farmers' awareness of scientific fertilization will be significantly improved, which will curb the obvious increase in the use of basic fertilizers.
The overall development of DD has entered a new stage.
During the "Twelfth Five-Year Plan" period, China's fertilizer industry will develop in the direction of scale, low cost, high efficiency, environmental protection and differentiation, and basically form an industrial pattern of monopoly competition. The specific development trend includes the following aspects:
The cost-oriented competition mode has become the mainstream.
Fertilizer enterprises must adhere to the cost-leading strategy, implement the integrated development model, continuously extend the industrial chain, gradually improve their competitiveness and viability, and realize long-term sustainable development. Main reasons:
The first is the pressure of the competitive environment. Fertilizer products, especially basic fertilizers, are homogeneous, and the cost of raw materials accounts for a high proportion of sales revenue. For example, coal and natural gas account for more than 70% of urea production costs. In the case that the overall profitability of the industry is declining, only by reducing costs can we gain market competitive advantage.
Second, the impact of future rural land system reform. Land transfer will promote large-scale operation, obviously increase the large-scale purchase of chemical fertilizers and pesticides, and obviously improve the bargaining power of chemical fertilizer users, just as large-scale purchase can get lower discounts ... >>
Question 8: What is chemical fertilizer?
Definition of chemical fertilizer
Fertilizers made by chemical and/or physical methods contain one or more nutrient elements needed for crop growth. Short for chemical fertilizer. Fertilizers containing only one indicated content of nutrient elements are called unit fertilizers, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, trace macro-element fertilizer and trace element fertilizer. A chemical fertilizer containing two or three of the three nutrient elements of nitrogen, phosphorus and potassium, and its content can be marked, is called compound fertilizer or mixed fertilizer. The solubility of effective components of chemical fertilizer in water is usually the standard to measure the effectiveness of chemical fertilizer. Grade is the main index of chemical fertilizer quality, which refers to the percentage of effective nutrient elements or their oxides in chemical fertilizer products, such as N, P2O5, K2O, etc. ; CaO、MgO、S； Boron, copper, iron, manganese, molybdenum and zinc.
History of chemical fertilizer production
Fertilizer production in eastern Fujian began in 1958. At the end of 1960s, Fu 'an, Ningde and Gutian successively introduced synthetic methods to produce bicarbonate. 1977, Gutian chemical fertilizer plant created the spiral flow screen method, which realized the full combustion of carbonized briquette to make gas, and the annual output increased from 3000 tons in the early 1970s to 5000 tons. In the early 1980 s, Mindong Ammonia Plant carried out a comprehensive technical transformation: the raw coal used for gas production was selected and purified to reduce impurities in briquette and increase carbon content; Adjust the temperature of gasifier and select catalyst to improve the conversion rate of feed gas and the gas output of a single gasifier; Adjust the ratio of nitrogen to hydrogen and the pressure and temperature of reaction gas in the synthesis tower to improve the conversion rate of raw gas to ammonia, promote the reaction speed and increase the amount of ammonia produced in unit time; Transform water cooler and heat exchanger to make full use of heat energy and reduce waste. In the mid-1980s, Gutian Chemical Fertilizer Plant was reformed, and the heat exchange network technology device of Provincial Chemical Design Institute was introduced. By changing the circulating hot water from synthetic heating to refined heating, the cascade utilization of energy is realized and energy consumption is saved. The cost per ton of ammonia has been reduced to 1 14 yuan, and the main equipment has become the third generation advanced equipment in the small ammonia industry in China. The annual output of synthetic ammonia has increased from 8,000 tons to10.2 million tons. In the late 1980s, Gutian Chemical Fertilizer Plant continuously improved and reformed various supporting projects, so that the annual output of ammonium carbonate exceeded 40,000 tons, the nitrogen content was > 16.6%, the moisture content was < 5%, and the product quality reached the national second-class standard.
The role of chemical fertilizer in increasing agricultural production
China is a populous country, and grain production plays an important role in the development of agricultural production. Usually, the way to increase grain output is to expand the cultivated land area or increase the output per unit area. According to the national conditions of China, there is little potential to continue to expand the cultivated land area. Although there are still many uncultivated land in China, most of them have problems of high investment and great difficulty. This determines that the grain production in China must take the road of increasing the output per unit area.
Fertilization can not only improve soil fertility, but also improve crop yield per unit area. Chemical fertilizer is the most basic and important material input in agricultural production. According to FAO statistics, chemical fertilizer accounts for about 40% ~ 60% of the total crop yield increase. China can feed 22% of the world's population with 7% of the world's arable land. It can be said that chemical fertilizer played a decisive role.
At present, the output and usage of chemical fertilizers in China.
The output of chemical fertilizers in China has reached 29.56 million tons (pure nutrients, the same below) from 65438 to 0998, accounting for 19% of the world's total output, ranking first in the world. The consumption of pure nutrients in China 1998 chemical fertilizer reaches 38160,000 tons, ranking first in the world.
Although China ranks first in the world in terms of total output and consumption of chemical fertilizers, this does not mean that China is also in a leading position in the technology of rational use of chemical fertilizers. On the contrary, there are serious unreasonable and unscientific problems in the application of chemical fertilizers in some rural areas of China, which have caused waste of chemical fertilizer resources, increased agricultural costs and reduced farmers' income, and need to be changed urgently.
China is a big producer and consumer of chemical fertilizers. With the adjustment of rural production structure, the demand for chemical fertilizers will continue to increase. In 2006, China will completely abolish the agricultural tax. With the improvement of grain price, grain planting area and farmers' enthusiasm for growing grain, it is estimated that the demand for chemical fertilizer will reach 50 million tons in 2006. From June to June, 2005, chemical fertilizer in China showed a good growth momentum. From June to June, the national fertilizer accumulated 24 1 19800 tons, up1/0/.7% year-on-year. Among them, the output of nitrogen fertilizer 17524900 tons, increased by 10.4%, the output of phosphate fertilizer1000 tons, increased by 9.6%, and the output of potassium fertilizer1kloc-0/3400 tons, increased by 54.5%.
