我省是全国夏大豆主要产区之一,种植历史悠久,近年来大豆生产出现徘徊不前局面,为了尽快把大豆生产搞上去,针对大豆栽培技术上的问题,提出几点意见:一、选用良种:当前大豆产量不高的一个重要原因是品种混杂退化。推广种植优良品种,产量可提高20%左右,每亩能多收大豆50斤左右。近几年来,我们从外地引进了一批大豆良种,连续进行了多点试验,结果是:跃进五号、徐豆四号、科系四号,商丘7608等表现产量较高;郑州135、郑州126、周农一号、周7502、建国一号、勤俭五号等早熟良种,适合大豆玉米间作种植。二、犁垡种豆:麦收后犁垡或圆盘耙灭茬播种大豆,一般比铁茬种豆增产20%左右,1978年周口镇农科所和黄庄大队科研站联合试验结果:犁垡种大豆单产211.8斤,耙地灭 Our province is one of the main producing areas of summer soybean in our country. It has a long history of planting. In recent years, the production of soybean has stagnated. In order to quicken the production of soybean, we put forward some suggestions on the technical problems of soybean cultivation. First, Seed: One of the main reasons for the current low soybean yield is that the hybrids degenerate. Promote the cultivation of fine varieties, yield can be increased by about 20%, about 50 pounds of soybean per acre can be received. In recent years, we have introduced a number of soybean varieties from the field and conducted many consecutive tests. The results showed that: Yuejin No.5, Xudou No.4, No.4 Branch and Shangqiu 7608 showed higher yields; Zhengzhou 135 and Zhengzhou 126, Zhounong One, Zhou 7502, Jianguo One, Qinjian V and other precocious varieties, suitable for planting between soybean and corn. Second, the plow beans beans: wheat harvest after harvest plow or disc harrow stubble sowing, generally increased than the stubble crop iron 20%, in 1978 Zhoukou Town Institute of Agriculture and Huang Zhuang Brigade station joint test results: plow Soybean yield 211.8 kg, harrow to off
