在毛主席革命路线指引下,我们贯彻“以粮为纲,全面发展”的方针,摆正粮豆关系,摸索出夏大豆“六喜六怕”生育特性,改变生产条件和栽培技术,夺得了夏大豆连年丰收,1974年259亩夏大豆,平均亩产359.4斤,其中34亩单产467.5斤,粮豆合计亩产达1,163斤。一、喜塇活土,怕板结大豆是直根、深根作物。根在幼苗期长的很快,两片真叶长出后不几天,主根可达6寸以上。根瘤菌是好气性细菌,土壤保持较好的透气性,能增加根瘤中根瘤菌的固氮能力。因此,地平土塇能
Guided by Chairman Mao’s revolutionary line, we implemented the principle of “taking grain as the key link and all-round development”, put squarely on the relationship between grain and beans, and worked out the characteristics of reproduction and development of summer liu xi liu xi fei, changed production conditions and cultivation techniques, and won the Summer soybean harvest year after year, in 1974 259 acres of summer soybeans, the average yield of 359.4 pounds, of which 34 acres yield 467.5 pounds, grain beans total mus of 1,163 pounds. First, hi 塇 live soil, fear of compaction soybean is straight root, deep root crops. Roots grow quickly in the seedling stage, two real leaves grow a few days later, the main root up to 6 inches or more. Rhizobium is aerobic bacteria, the soil to maintain good permeability, can increase the nodulation of rhizobium nitrogen fixation capacity. Therefore, the level of soil 塇 can
