据文献记述,大豆种子发芽的适宜土壤含水量为20—24%。种子发芽时对水分的要求随种粒的大小而异,小粒比大粒需水量为少。但就植株的生育来说,大粒种子优于小粒种子长出的植株。本试验目的在于进一步明确土壤不同含水量和种子不同粒重对大豆出苗及生育前期营养生长的影响,供大豆生产参考。
According to the literature, the appropriate soil moisture content of soybean seed germination is 20-24%. Seed germination of water requirements vary with the size of seed, small particles than large grain water demand less. However, for plant growth, large seeds are preferable to those grown from small seeds. The purpose of this experiment is to further clarify the different soil moisture content and seed weight of different seed weight on the emergence of soybean and vegetative growth of early growth for soybean production reference.
