发芽率高的稻种,一般成秧率较高;反之,发芽率低的不仅成秧率低,且秧苗生长缓慢,容易烂秧。因此,认真做好发芽试验,及早发现并淘汰发芽率低的稻种,为生产准备足够优良稻种,是备耕工作中不可忽视的一环。在初春气温较低的情况下,农村社队如何做好水稻种子发芽试验呢?我们的实践认为采用热水瓶保温催芽方法较好。方法简便易行,较准确,且保温保湿好,发芽快,还能防鼠害。具体作法是:首先取好有代表性的样品。同一品种贮藏 The high germination rate of rice varieties, generally higher rate of planting seedlings; the other hand, the low rate of germination not only into low seedling rate, and slow growth of seedlings, easy to rot seedlings. Therefore, earnestly germination test, early detection and elimination of low germination rate of rice, production for the preparation of good enough rice is spare part of the work can not be ignored. In the early spring temperatures are low, the rural community how to do a good job of rice seed germination test? Our practice that the use of thermos insulation method is better. The method is simple and easy to use, more accurate, good in keeping warm and moisturizing, quick in germination, and capable of preventing rodents. The specific approach is: first take a representative sample. The same variety of storage
