比较多的大豆品种易受冷害,使播期受到温度限制。我们曾提出过三种预防措施。但要将这些措施应用于生产实践,还有一定难度。且温水预浸后有时发现子叶有断裂现象,故企图寻找新的简便易行的方法。 Tao曾报道大豆种子起始含水量对电导测定有影响。含水量低于8.8％的种子直 Soybean varieties are more susceptible to chilling injury, so sowing time by the temperature limit. We have put forward three kinds of precautionary measures. However, to apply these measures to production practice, there are still some difficulties. And after warm water pre-impregnation sometimes found cotyledons have broken, so the attempt to find a new easy and convenient method. Tao has reported that the initial water content of soybean seeds has an influence on the conductivity measurement. Seeds with a water content of less than 8.8% are straight
