种子萌动需要一定的水分、温度、氧气等条件,不同的作物或同一作物的不同品种种子发芽时对外界条件的要求是不同的,按照GB/T 3543.4-1995农作物检验规程规定的标准试验,大多数种子的发芽率和田间种植的出苗情况结果一致,但笔者经过几年的实际操作,发现几种特殊情况,需要不同的水分标准,才能得出正确的发芽结果。现将本人的实践做以简单的归纳、整理。 Seed germination requires a certain amount of water, temperature, oxygen and other conditions, different crops or different varieties of the same crop seed germination requirements of the external conditions are different, according to GB / T 3543.4-1995 Crop Inspection Regulations of the standard test, large The germination rate of most seeds is the same as that of the seedlings planted in the field. However, after several years of actual operation, the author discovered several special situations and required different water standards to obtain the correct germination results. Now my practice to do a simple summary, finishing.
