Intercropping soybeans to make money and fat
"My soybeans are only half of the area planted, and I don't expect such a high yield!" On October 23, an investigation team consisting of academicians of the Chinese Academy of Engineering, consultants of the modern soybean industry technology system, and chief experts, The Sichuan Agricultural University and the Sichuan Agricultural Technology Extension Station and other units researched and promoted the intercropping of soybeans for inspection and production. When they learned that their 1.8 mu of soybean per mu yield reached 141.5 kg, the head of the household, Han Dafen, was excited.
It is understood that in the 1990s, Professor Yang Wenzhao, vice president of Sichuan Agricultural University, studied the traditional three-crop "wheat/jaw/苕" model in the hilly area of ​​central Sichuan, and saw that there were many migrant workers in the countryside and the land was infertile. In the test, soybeans with less planting workers were used instead of red stalks to fertilize the ground. In the absence of funding for the project, the model of the new three-cooked “Mai/Jade/Bean†model has been carried out, and trial and demonstration began in 2002. With the maturity of technology, it has been widely welcomed by farmers in the demonstration area.
The academician of the Chinese Academy of Engineering and the head of the inspection team, Ge Wei, are very satisfied with the production of soybeans in Sichuan. He introduced that a large number of imported soybeans in China, due to the relatively low efficiency of northern soybeans, and the serious competition with corn and rice, The promotion of planting soybeans in Sichuan and Southwest China will effectively alleviate China's dependence on imported soybeans. This technology has changed the amount of chemical fertilizer used, the amount of labor, and the intensity of labor, by changing the red glutinous rice into soybeans, changing the mixture as a set, changing the spring to summer sowing, changing the thinning to dense planting, and changing the ridge ridge to cover the no-till straw. Soil erosion has enhanced crop drought resistance and increased production and income.
The province's intercropping soybeans have grown from 1.294 million mu in 2006 to 3.5 million mu this year, which makes Yang Wenxi very gratified. He revealed that “through the integration of supporting technologies and innovations, we have selected 20 suitable sets for the relevant units according to local conditions. The mid-late maturity, shade-tolerant and high-yield varieties solved the problem of continuous cropping of soybeans by changing the belts. By adjusting the soybean water requirement and the precipitation law, the science avoids the soybean emergence period and the flowering period drought, becoming me. One of the eight major water-saving technologies in the province in 2007."
