大豆是本县的主要种植作物之一,每年播种面积20万亩左右。为探讨不同播期对春、夏大豆产量及其性状的影响,以确定本地区春、夏播的适宜时期,县科委1981年在店子公社陈家大队试验。春播品种“农革1号”,分四期播种,小区面积3.5厘;夏播品种“7602”,也分四期播种,小区面积3.9厘。重复3次。试验地为沙壤土,肥力中等。
Soybean is one of the main crops grown in the county, with an annual sown area of about 200,000 mu. In order to investigate the effect of different sowing date on spring and summer soybean yield and its traits, in order to determine the proper period of spring and summer sowing in this area, the county science and technology commission experimented with the Chen family brigade in Dianzi commune in 1981. Spring sowing variety “Agricultural leather 1”, divided into four seeding, residential area of 3.5%; summer sowing varieties “7602”, also divided into four seeding area of 3.9%. Repeat 3 times. Test for sandy loam, medium fertility.
