一、看地力和品种定密度 一般上中等肥力、植株高大的中晚熟品种如豫豆10号、12号、17号、21号、22号、诱变30等,667平方米留苗10000～12000株;中等肥力12500～15000株;旱薄地、早熟品种如豫豆14号、15号、20号、23号等,667平方米留苗14000～18000株。种植方式可4O厘米等行距,50厘米×30厘米宽窄行。但无论什么样的密度,哪一种种植方式。都不能缺苗断垄。
First, to see the force and the variety of fixed density Generally moderate fertility, tall plants in the late varieties such as Yudou No. 10, No. 12, No. 17, No. 21, No. 22, mutagenic 30, 667 square meters to stay 10000 ~ 12000 Medium fertility 12500 ~ 15000; dry land, early varieties such as Yudou No. 14, No. 15, No. 20, No. 23, etc., 667 square meters of seedlings 14000 ~ 18000. Planting methods can be 4O cm spacing, 50 cm × 30 cm wide and narrow lines. But no matter what kind of density, what kind of planting. Neither lack of seedlings broken ridge.
