从1972年以来,我们进行了夏大豆高产栽培试验,摸索了一些高产栽培措施,使夏大豆的产量不断提高。1975年在毒素病十分严重的情况下,92亩夏大豆平均亩产302斤,其中有44亩单产390斤,有5亩单产475斤。1976年60亩大豆遭受低温、干旱等灾害,平均亩产257斤,其中10亩试验田,平均单产513斤。深耕细耙平整土地过去麦收后不灭茬直接播种,或稍加灭茬就播种,结果土壤板结,草荒严重,大豆生长不良,产量低。经过几年试验证明,麦收后随即用
Since 1972, we conducted high-yield cultivation trials of summer soybeans and explored some high-yielding cultivation measures to increase the yield of summer soybean. In 1975, when the toxin was very serious, the average yield of 92 mu of summer soybean was 302 kg, of which 44 mu was 390 kg and 4 mu was 5 mu. In 1976 60 acres of soybean suffered low temperature, drought and other disasters, the average yield of 257 kg, of which 10 acres of experimental field, the average yield of 513 pounds. Deep cultivating fine rake to level the land In the past, the wheat was harvested and directly stubbled, or sown with a little stubble. As a result, the soil compacted, grass was severely weakened, soybean growth was poor, and the yield was low. After several years of testing proved that the wheat harvest immediately after use
