深播苗在墒情适宜时立即用齿耙进行麦地松土、清棵、改善土壤的通透性,促进及时出苗和分蘖。疙瘩苗防治方法①掌握科学合理的播量,一定要依地力定产量,依产量定穗数,依穗数定冬前分蘖总数,依冬前分蘖总数定基本苗数,最后依基本苗数定播种量,注意冬前总蘖数为要求穗数的120%左右。在播前要做好种子的发芽率测定。②播前精细整地,整后的土地
Deep sowing seedlings in the soil moisture immediately when the rake rake for soil, clearing trees, improve soil permeability and promote timely emergence and tillering. Pimple seedling prevention and control methods ① master of scientific and rational sowing, must be determined according to the yield, according to the yield spike number, according to the number of spike set the total number of tillers before winter, according to the total number of tillers before the basic number of seedlings, and finally the number of basic seedlings set Seeding rate, attention to the total number of tillers before winter is required about 120% of the spikes. To sow seed germination rate before sowing. ② pre-sowing fine preparation, the entire land
