The National Science and Technology Support Program (Agriculture Sector) project “Research on the Quality and High-Efficiency Production Techniques of Daejeon Economic Crops and Characteristic Cereals” has progressed rapidly. The results of demonstration development have been remarkable.

At present, the five high-quality and high-efficiency production technology systems for soybean, cotton, rapeseed, peanut, and potato have initially taken shape. With high-quality varieties and agricultural machinery as the carrier, nine sets of technological models including mechanized "deep and narrow density" cultivation, no-tillage cultivation of rapeseed, high-yielding cultivation of spring peanut machine film, and efficient cultivation of potato intercropping were formed. Soybean super-high yield research has achieved the highest yield per unit of 253.3 kg per mu under no irrigation conditions. It has obtained super high yield records of 210 kg per mu for cotton, 249.9 kg per mu for rape, 671.2 kg per mu for peanut, and 4208 kg per mu for potato. In the past two years, 48 ​​demonstration bases for five economic crops have been established, of which the core area is 102,000 mu, the demonstration area is 4.09 million mu and the radiation area is 22.319 million mu. In 2006, soybean production increased by 110 thousand tons, rapeseed yield increased by 23,000 tons, and peanut production increased by 172,000 tons. In 2007, soybean production increased by 56200 tons, cotton increased by 472.5 tons, rapeseed production increased by 45,200 tons, peanut production increased by 172,000 tons, and potato production increased by 401,000 tons. Ton. Compared with the first three years of the project, the soybean yield per acre in the test area in 2007 reached 155.5 kg, 5.4% more than the average mu of the first three years of the project; the yield of cotton increased by 20%; the yield of rapeseed mu increased by 28.1%; the yield of peanut increased by 11.3%; and the yield of potato increased by mu. 21.5%. From 2006 to 2007, the five major economic crops have added economic benefits of 2.693 billion yuan.

The preliminary research on the research and demonstration of special varieties of coarse grains and complementary high-yield technologies has achieved initial success. Focusing on the selection, breeding, value-added use, and green supply chain of cereals, sorghum, barley, oats, and other new varieties of miscellaneous grains, the research on molecular markers and breeding techniques of miscellaneous crops was carried out to create and screen out a batch of high-quality, trait-specific, disease-resistant, and stress-resistant varieties. Herbicides and other excellent new materials (23 millet, 18 for sorghum, 20 for barley, and 22 for mixed beans) were selected to produce a variety of fine grains that are high in quality, high in yield, drought resistance, strong in resistance, and suitable for industrial production. New varieties. Among them, 15 varieties (12 varieties of millet, 7 varieties of sorghum, 8 varieties of barley, 2 varieties of oats, 1 variety of buckwheat, 18 varieties of buckwheat) and 33 species of provincial (reviewed) varieties were set up through the national review (review); Integrated 18 varieties of supporting cultivation techniques and technical specifications, and completed and promulgated the implementation of the technical regulations and 7 local standards. The achievement of these achievements has played a very important role in promoting the replacement of miscellaneous grains in China and improving the standardization, scale, and industrial production of miscellaneous grains.
