种子包衣是防治种子传播病害和土壤传播病害及地下害虫的一项省工高效的新技术。在推广这项新技术中，存在着部分种子发芽率较包衣前降低幅度过大，导致大田出现缺苗的现象。为此，我们就不同发芽床和不同的发芽方法对包衣种子发芽率的影响进行了试验。１材料和方法１．１... Seed coating is a province-efficient new technology for controlling seed-borne diseases and soil-borne diseases and underground pests. In the promotion of this new technology, there are some seeds germination rate lower than before the coating was reduced, leading to shortage of seedlings in the field phenomenon. To this end, we tested the effect of different germination beds and different germination methods on the germination rate of the coated seeds. 1 materials and methods 1.1 ...
