摘要
Abstract
[Objective] To make sure proper sowing date of Ningxia soybean. [ Method] 17 soybean varieties were tested in seven patches to research the effect of different sowing dates on growth period, yield, properties and agronomic traits of soybean. [ Result ] The soybean sowed from April 23 to June 23 matured normally, those which were sowed from April 23 to May 13 had higher yield; the yield, plant height, node number on stem, grain number of single plant and 100-pellet weight gradually reduced and the growth period was shortened as the sowing date delayed. [ Conclusion] As for spring sowing, the proper sowing date of soybean in Ningxia lasts from the late April to early May while for sum mer sowing, the proper sowing date is from middle June to early July.关键词
