During his work in the National Institute of Rice and Wheat Improvement, Zhao spent a lot of energy on the national rice variety comparison test, physiological, genetic and cross breeding research, and at the same time set up a local rice inspection and identification institute to expand his work to five provinces: Anhui, Jiangxi, Hunan, Sichuan, Guangxi and Yunnan. It has also established rice inspection institutions in Anhui, Jiangxi and Hunan provinces to promote the improvement of rice quality and the establishment of production and marketing systems. In this way, there is a relatively perfect implementation plan from rice breeding research, breeding promotion and product sales. A number of rice breeding talents have been trained, and a number of high-yield varieties, such as Maozitou, Nante and Shengli Indica, have been bred and popularized in the middle and lower reaches of the Yangtze River, all of which belong to early-maturing rice varieties in China. At that time, China still lacked advanced rice breeding research. Besides being busy with teaching, scientific research and popularization, he also wrote many books on rice breeding, such as Theory and Practice of Rice Breeding in China, which had a great impact on improving the level of rice breeding in China. Zhao Lianfang took scientific research and personnel training as her career from the beginning. Seeing the decline of China's national conditions and the poverty of farmers, he transferred to the Agriculture and Forestry Administration on 1934, and made a big wish of "developing academics by career". After more than ten years, I traveled all over the country, considering the overall situation of agriculture and forestry, adjusting measures to local conditions, increasing grain and cotton production, vigorously advocating export agriculture and rural cooperation, promoting the combination of agriculture, industry and commerce, and promoting rural economic development, mainly including:
1. Revitalize the tea industry. At that time, the tea industry in China still lacked overall planning. The tea area is scattered, the tea garden is scattered, the planting and processing technology is backward, and the benefit is not good. After in-depth investigation and study, Zhao decided to improve from three aspects: production, production and sales. Anhui black tea production area was selected to establish Qimen black tea improvement farm, and German machinery and technology were invested. At the same time, people were sent to Japan to study the experience of Japanese tea garden close planting. Demonstration tea farms were established in Anhui, Jiangxi and other tea areas, and the planting of gypsophila paniculata was changed to strip rows, which significantly improved the yield and quality, and gradually formed a unified system of production, production and marketing. The success of Qimen Black Tea Improvement Farm has had a great impact on the development of China tea industry.
2. Promote the improvement of animal husbandry in northwest China. The loess plateau in northwest China has serious soil erosion, nine droughts in ten years and low grain yield, so it is extremely important to develop animal husbandry. Zhao cooperated with the Yellow River Water Conservancy Commission to advocate the planting of pasture, which not only preserves soil and water, but also provides feed. I set up an animal husbandry improvement farm in Lanzhou, and personally visited Shanxi, Shaanxi, Gansu and Qinghai provinces. It was extremely difficult to trace back to Qinghai along the Yellow River and finally reach Lop Nur, Xinjiang. On the way to an investigation, I got stuck in the mud at night and almost died. Through investigation, key measures such as developing pasture, improving cattle and sheep breeds and preventing epidemics were clearly put forward, and excellent breeding animals were introduced from the United States, and capable professionals were arranged to work in improved farms to promote the development of local animal husbandry.
3. Increase grain output and strive for rice self-sufficiency. After the "September 18th Incident", the Japanese invaders' ambition to invade China was desperate. In order to focus on the long-term anti-Japanese war, Zhao deeply felt the strategic urgency of solving the problem of food self-sufficiency, and put forward the "National Rice Self-sufficiency Plan", which was jointly reviewed and approved by the State Economic Commission, the Executive Yuan Cooperation Committee and the National Defense Economic Research Association. It was decided to establish the National Institute of Rice and Wheat Improvement, with Zhao and Shen as the heads of the rice and wheat cultivation group respectively. In order to realize this plan, Guangdong, which is seriously short of food in Chair Zhao, cooperated with Sun Yat-sen University to make a plan to improve the province's output by cultivating talents. Later, he went to Fujian to promote the establishment of Fujian Agricultural Reform Department and Mixiang Improvement Committee to improve rice. Finally, establish a provincial rice and wheat improvement institute in Sichuan, set up experimental sites in various districts and implement improvement measures; Jiangsu, Zhejiang and Anhui provinces in the east of China rely on the foundation of scientific research and popularization cultivated while teaching in CUHK. On the premise of ensuring the increase of rice production, we should seize the production and marketing links, establish a rice inspection system and formulate rice grading inspection standards. At the beginning of 1937, rice inspection institutes in Hunan, Anhui and Jiangxi provinces were established one after another. Originally, I hoped to carry out rice inspection, prevent low-cost acquisition and smooth sales channels. Because of the outbreak of War of Resistance against Japanese Aggression, it could not be put into practice. During the War of Resistance against Japanese Aggression period, the Kuomintang government moved to Chongqing, and the country was in trouble. After Zhao arrived in Sichuan, he served as the technical director of the Central Agricultural Laboratory and the chairman of the Sichuan Agricultural Improvement Committee in Chengdu, coordinating the agricultural improvement work in the whole province. After careful investigation and consultation, it was decided to merge the experimental research institutions of agriculture, forestry, animal husbandry and fishery in this province into Sichuan Agricultural Improvement Institute, with Zhao as the first director. At this time, agricultural professionals from all over the coastal areas fled from the enemy-occupied areas to Sichuan. Zhao regardless of provincial origin, school, equally, recruiting talents. In view of the extraordinary situation in wartime, he vigorously developed Sichuan agriculture and supported the national anti-Japanese war. At that time, four principles of agricultural improvement in Sichuan were formulated, as well as specific implementation steps and planned projects, which were posted on the bulletin board of the institute for people inside and outside the institute to see at a glance. These four principles are:
1. Increase grain and cotton production to meet the needs of military supplies and people.
2. Develop export agricultural products and increase national financial resources.
3. Cultivate rural sideline to increase farmers' income.
4. Reserve national agricultural recovery resources after the war, so as to quickly revive national agricultural and forestry production after the victory of the Anti-Japanese War.
The biggest difficulty in implementing this plan is the problem of funds. Before the establishment of Sichuan Agricultural College, all the funds of Agriculture, Forestry, Animal Husbandry and Fishery College were only 300,000 yuan, and it took about 8 million yuan to complete the above four tasks. In order to win funds, Chair Zhao attended the provincial government meeting as a non-voting member, emphasizing the urgency and importance of gathering talents to promote agriculture and the strategic significance of rejuvenating the country, and finally passed a budget of 3 million yuan. On the other hand, Zhao appealed to the relevant departments, and the director of the State Grain Bureau gave the Sichuan Academy of Agricultural Sciences 2 million yuan to increase grain production. Zou Bingwen, deputy director of the Export Materials Increase Committee, negotiated with the organizer to allocate 2 million yuan; Together with the subsidies from other agricultural and forestry professional budgets of the Ministry of Agriculture and Forestry, the total amount of funds in 194 1 has increased to150,000 yuan, and there are 4 million yuan of overdraft loans from Chinese, Chinese, foreign and agricultural companies, so that the work plan can be implemented smoothly. Various professional laboratories, showrooms, seed farms, seed farms and nurseries have been established and improved, and serum factories, bone meal factories and pharmaceutical factories have been added to meet production needs and increase income. At that time, the staff of Sichuan Agricultural College increased to 125 1. In order to strengthen the organization and leadership, the province has established the Agricultural Technology Extension Committee, which consists of 108 supervision area and 104 county agricultural technology extension institute, forming a set of scientific research extension system. In the past four years, improved cotton seeds, wheat seeds, rice seeds and silkworm eggs have spread to more than 50 counties, and some farmers have changed their seeds from hundreds of miles away. Improved variety promotion, animal epidemic prevention, pest control, etc. It has brought benefits to farmers and enhanced the food and clothing of the soldiers and civilians in the anti-Japanese war throughout the country, and has been commended by the government. After the Sino-Japanese War of 1894-1895, Taiwan Province Province became a colony of Japanese invaders. Agricultural production is limited to providing food, sugar and raw materials, and the bulk income is known to be monopolized by the Japanese. Taiwan compatriots can only manage some primary products to make a living. 1945 Japanese invaders surrendered, and after the recovery of Taiwan Province Province, Zhao, as Commissioner of Agriculture and Forestry Department and Director of Agriculture and Forestry Department of the Chief Executive's Office of Taiwan Province Province, led 15 experts to Taiwan, vigorously reorganized institutions and comprehensively planned plans to revitalize agriculture. With his outstanding talent, rich experience and superhuman energy, he laid a good foundation for the recovery and development of agriculture in Taiwan Province Province in just two years. The main results are as follows:
1. According to the specific situation of Taiwan Province Province at that time, three goals were put forward: First, consolidate grain production and improve people's lives; The second is to develop the export of agricultural products and increase foreign exchange income; The third is to fully supply industrial raw materials and expand agricultural products processing enterprises.
2. Put forward four strategies for agricultural construction: First, maintain water and soil, build water conservancy projects to achieve stable and high yield; The second is to implement planned production to ensure the balanced development of industry and agriculture; Third, formulate agricultural standards and standardize agricultural products to meet the needs of export trade; The fourth is to strengthen the training of farmers' groups and enhance rural culture.
3. Carry out development planning by region: first, level off agriculture, develop water conservancy, increase fertilizer, improve varieties, improve farm management and promote mechanization; Second, mountain agriculture, high mountains are forests, low mountains are gardening, hilly feed, afforestation, soil and water conservation, rational logging and forest industry research; Third, marine agriculture. Taiwan Province Province has a vast sea area and rich resources, so it is urgent to develop fishery.
In order to achieve the above tasks, the agricultural and forestry institutions have been completely reorganized. While strengthening administrative leadership, various professional scientific research institutions have been established, and four joint-stock companies in Taiwan Province Province, namely, tea, pineapple (pineapple), aquatic products and animal husbandry, and two preparatory offices for agricultural products and forest products, have been established to promote the enterprise management of agriculture and forestry.
After the retrocession, agriculture and forestry in Taiwan Province Province gained new vitality rapidly and embarked on the road of healthy development. In addition to working in agricultural education, scientific research and administrative departments, Zhao devoted himself to social activities and public welfare undertakings with a high degree of patriotic enthusiasm and work enthusiasm, and advocated all-round and multi-sectoral cooperation. He holds dozens of posts, mainly including: Rural Rehabilitation Committee, Resources Committee, Local Autonomy Planning Committee, Agricultural Education Committee, Grain Increase Committee, Agricultural Standards Drafting Committee, and Peasant Association Counseling Committee. All of them employ him as a member. 1958 was elected as an academician of Academia Sinica, and served as the chairman of Taiwan Province Agriculture and Forestry Company, the director of Land Bank, Cooperative Treasury and Sugar Company, and also served as the chairman of private Yiguang Kindergarten, which shows that he is an activist integrating into society.
In his later years, Zhao did not make any contribution to the mainland of China in the case of the split between the two sides of the Taiwan Strait. He went abroad and devoted himself to international agricultural technical services, making important contributions to increasing grain production in developing countries in the Middle East and South America. /kloc-0 was hired by FAO in 1955. First, he went to Iraq to help increase rice production. After three years' efforts, through improving varieties, cultivating pure rice seeds, rational irrigation and fertilization, adopting new agricultural machinery, improving farming system and controlling pests and diseases, the rice yield in Iraq has doubled, and local technical talents have been trained. The rice seeds suitable for local cultivation have been well received. 1963 was hired as a consultant to Dominica and the Ministry of Agriculture for two years, helping to improve rice production technology, focusing on increasing rice yield, establishing rice experimental fields for Dominica, improving local varieties, introducing exotic varieties, and carrying out irrigation, applying chemical fertilizers, controlling pests and diseases, eliminating weeds, improving farm tools and other measures, with obvious yield increase effects. At the same time, agricultural training courses will be held to recruit agricultural school graduates to improve. A number of improved rice varieties such as Jianong 242, Hsinchu 56, Egyptian Nile, Taichung Indica 1 have been selected for the local area, which has made important contributions to improving the rice production level in Dominica and won the highest national medal. In addition, he has visited Laos, Jordan, Iran, Egypt, Turkey, Lebanon and other countries to give lectures and help improve production technology, which has also contributed to strengthening international cooperation and exchanges in agricultural science and technology and enhancing the friendship of people around the world.
Zhao is a frank, outspoken, responsible, tireless and backward-looking scientist and social activist, deeply remembered and respected by people.
