种子包衣是近年来研制出的一项加工处理种子的新技术。其基本原理就是将种子与特制的种衣剂充分搅拌,使每粒种子表面涂上一层均匀的药膜,形成种衣。采用这种方法,较多年来沿用的全田开放喷药、病虫分治处理措施,既简便易行、减少程序,又可减轻环境污染。其特点是不同类型的包衣种子可用于不同的生产需要。其中包括:(1)延缓发芽的包衣。即通过种子包衣处理,使土壤水分向种子内移动减慢,种子发芽延迟,进而延迟生长和开花,这种包衣,一般用于繁制杂交种。(2)微量元素包衣。即用
Seed coating is developed in recent years, a new seed processing technology. The basic principle is to seed and special seed dressing mixing, so that each seed surface coated with a uniform film, the formation of seed coat. With this method, the whole field open spray, pest and disease treatment measures adopted over the years are both simple and easy, reduce procedures and reduce environmental pollution. It features different types of coated seeds that can be used for different production needs. These include: (1) Delaying germination of the coating. That is, the seed coat treatment, the soil moisture to move within the seed slowed, delayed seed germination, and then delay the growth and flowering, this coating, generally used for breeding hybrids. (2) trace element coating. That is to use
