目前,检验种子发芽率常用的发芽床有滤纸、毛巾纱布混合、砂等。根据我站几年的发芽试验表明,不同季节采用不同芽床测定种子发芽率比单一使用一种芽床效果更佳。 1 夏季采用滤纸做芽床发芽效果好。其优点有三: 1.1 通透性较好,种子不易感菌。夏季由于气候炎热,空气中各种菌多,发芽时水气控制一旦失调,种子极易感染病菌而腐烂,从而影响最后结果。毛巾卷法就易出现这种情况。
At present, the test of germination rate of germination bed commonly used filter paper, towel gauze mixture, sand and so on. According to my station germination test for several years, it showed that using different buds in different seasons to determine the seed germination rate is better than using a single bud bed. A summer filter paper bud germination effect. The advantages of three: 1.1 permeability is better, the seeds are not susceptible to bacteria. Summer due to hot weather, a variety of bacteria in the air, germination, once the imbalance in the control of moisture, the seeds susceptible to bacteria and decay, thus affecting the final result. Towel roll method is prone to this situation.
