我县位于黑龙港流域,由于自然条件较差,加上科技普及不够,生产力水平较低,造成大豆生产产量低而不稳,其经济效益甚微。为扭转这一局面,自1989年以来,我们结合省、地科技部门下达的“大豆丰收计划”课题,成立了大豆高产栽培攻关领导小组,试图探索一条适合本地高产栽培的途径和拟定一个大致的生产模式。经过两年的努力,1990 My county is located in the Heilongjiang River Basin, due to poor natural conditions, coupled with insufficient technology, low productivity, resulting in low and unstable soybean production, its economic benefits are minimal. To reverse this situation, since 1989, in conjunction with the “Soybean Harvest Program” issue issued by the provincial and prefectural science and technology departments, we have set up a leading group of high-yielding cultivation of soybean to try to find a suitable way for local high-yield cultivation and to draw up a general Production mode. After two years of hard work, 1990
