参谋提示又到了育苗的季节,很多种植户在育苗时发现,即使使用基质育苗,种子的出苗率也会很低,他们一般把原因归结到种子的出芽率低、种子质量差等原因。但通过监测有些种子的质量和出芽率是合格的,那究竟是什么原因影响了种子的出芽率呢?种子发芽率是指在常规发芽试验中,第七天时已发芽的粒数占总供试粒数的百分比,发芽势是指在发芽试验中第三天出芽的粒数占总粒数的百分比。 The staff suggested that the breeding season again. Many growers found during seedling raising that the seedling emergence rate will be very low even when the seedling is used. They generally attribute the reasons to low germination rate and poor seed quality. But by monitoring the quality of some seeds and budding rate is qualified, then what is the reason that affects the seed germination rate? Seed germination rate is in the conventional germination test, the seventh day when the germination of the total number of particles The percentage of test grains, germination potential is the third day of the germination test in the percentage of the total number of particles of the number of buds.
