玉米是我社的主要粮食作物,除与小麦带种一部分外,主要是与大豆二比二间种,虽然玉米产量有所增加,但大豆严重减产,1976～1978年间种大豆的平均单产只有111斤.为了解决这个矛盾,提高大豆产量,我们在前石、东柳等农科队搞了不同形式的大垄玉米、清种大豆栽培试验,并进行大面积示范推广.1976～1978年大垄玉米、清种大豆、玉米与大豆 Maize is the main food crop of our society. Except for a part of the cultivated wheat, it is mainly composed of two to two species of soybean. Although the output of maize has increased, the yield of soybean has been severely reduced. The average yield of soybean grown from 1976 to 1978 was only 111 Kg In order to solve this contradiction and improve soybean production, we engage in the front stone, Dong Liu and other farming team engaged in different forms of large ridge corn, Qingcao soybean cultivation experiments, and large-scale demonstration and promotion .1976 ~ 1978 big ridge Corn, Clear Soy, Corn and Soy
