Technical team to carry out a preliminary survey
Summer three geng will be into the ambush, the Yellow River a few bends northeast of the Hetao Plain, Inner Mongolia Autonomous Region, Bayannur City, Bayannaoer County, Wuhuyuan County, Tianjitai Town, Jingyanglin Village Qi five is improved saline land on the sunflowers to take care of. Now his family's sunflower has not been over the calf, looking at the green sunflower he laughed, "Before 40 acres of saline soil iron hard and not seepage, an acre of even 50 kilograms of sunflower can not be hit."
Qi Wujia's land belongs to the heavy saline and alkaline "holding sauce barren" land, "planting sunflower has a pile, pick sunflower does not bear seeds," leading to half of the land at home all year round grain. "Now after the Agricultural Extension Center applied desulfurization gypsum, organic fertilizers, wind sand and mechanical deep-pine integrated technology improved, the soil is also soft and, every mu how to make a 200 kilograms of sunflower." Improvement of three years later, his family salt-resistant and drought-resistant sunflower seedling retention rate from 30% year by year to more than 89%, and now mu yield increase of 500-600 yuan. "Planting can't just bury your head in the sand, but also believe in science and use science!"
Comparison of soil improvement in the project area before and after the improvement of soil in the project area
"Look and smell" to the big data to be saline cure
"The world's Yellow River is rich in the river set, rich in the front set of the set of rich after the set of rich," Bayannur The city is located in the northeast corner of the Yellow River several words Bay Hetao Plain. Abundant water resources every year down the river to feed thousands of acres of good land, floods and droughts, not only makes the Hetao Irrigation District has become an important commodity grain and oil bases in northwest China, but also won the "grain silo" reputation.
"Every year nearly 4.7 billion cubic meters of Yellow River water into the irrigation area, due to the mineralization of the Yellow River water is about 0.6g/Kg, every cubic meter of Yellow River water contains about 0.6Kg of salt, the salt brought into the irrigation area every year is about 2.8 million tons." Wuyuan agricultural big data platform before the Inner Mongolia Menggrass saline land improvement engineering technology research center president Ma Ruiqiang pointed to the data on the display screen, said Bayannur City *** there are 10,728,000 acres of arable land, of which salinized arable land is 4,840,000 acres, accounting for the city's arable land area of 45.1%, accounting for 46% of the area of salinized arable land in the Inner Mongolia Autonomous Region.
"Winter and spring white, is not playing food" is the past Bayannur City, Inner Mongolia saline and alkaline real portrayal. "Previously, the family 40 acres of land has 16 acres will not be able to plant crops," Qi Wu said, salinized arable land soil fertility is low, soil crusting is serious, crop emergence difficult, saline land can only plant sunflower salt-tolerant crops. And Qi five family land, Wuyuan County, most of the heavy saline arable land without any output, a serious constraint on farmers and herdsmen to increase production and income and the comprehensive production capacity of agriculture and animal husbandry to enhance.
"Management of saline and alkaline land must first be given to the land quality 'pulse'," approached the Menggrass big data team for the Wuyuan County Agricultural Big Data platform developed by clicking on the saline and alkaline land distribution map, all the saline and alkaline land in accordance with the county of light, medium, and heavy scattered The big data of agriculture is the key to the development of modern agriculture. Agricultural big data is an important technical support for the development of modern agriculture, "We found that 'salt comes with water, salt goes with water' is the law of saline-alkaline land improvement through the soil sample collection and soil profile investigation of each village in Wuyuan County," said Menggrass saline-alkaline land improvement technician, pointing to the soil sample. Soil samples said, the local saline land types mainly include fluffy saline soil, horse urine saline soil, black oil saline soil, white stagnant soil and other types, we from the Menggrass ecological big data platform to call out the corresponding soil types of suitable native plants, developed saline land improvement of ecological packages, ameliorating agents, and other products, and then with the Menggrass company for many years with the chemical, physical, biological and other technological measures, to realize the saline land into a good field. "Only to the saline and alkaline land accurate 'pulse', in order to adapt to local conditions for local saline and alkaline land improvement 'search for medicine'."
