早稻种子包衣直播育秧研究

早稻不催芽直播育秧，抗寒力强，成秧率高，可早播、早熟和省工、省种。是传统育秧方法的创新。种衣剂有防治病、虫、鼠害和营养壮苗作用，它与直播育秧技术结合，可以不侵种直播干谷，又使种衣剂免于在浸种中溶解淋失，两者优势互补，合成一项具有高科技结晶，操作性强。新型实效，简单易行的育秧技术。

Study on Seed Coating Non-pregermination and Direct Seeding of Early Rice

The technology of non pregermination and direct seeding of early rice has good growing charactristics such as high capability of cold tolerance and high rate of seedling. Besides, it has Superiority of early sowing, early transplant and early cropping as well as saving labour and saving seed. It is also suitable for dry seedling, plastic tray seedling and raising rice seedling in factory. Seed coating formulation has effects on preventing and curing disease, insect and mouse and nourishing seedling. Generally the output can increase 5%. combined with non pregermination and direct seeding,it can sow dry seed directly without seed soaking. and prevent of leaching of seed coating formulation in seed soaking. Both of them display complementary superiority and form a scientific and operative sowing method containing new and high technology.
