小麦的播深以3～5cm 为宜。播种太深,幼苗出土消耗养分太多,出苗迟,麦苗生长弱,影响分蘖和次生根发生,甚至出苗率低,地中茎多节,无分蘖和次生根,越冬死苗率高。播种过深造成的危害,采取追肥浇水等措施,亦收不到补救效果,严重影响产量。所以小麦的播种不宜过深。我县的魏桥镇西刘村是我公司的小麦良繁基地,实行统一供种,统一播种,统一管
Sowing of wheat to 3 ~ 5cm is appropriate. Sowing too deep, too much seedlings unearthed nutrients, late emergence, wheat seedling growth is weak, affecting the tillering and secondary root emergence, and even the emergence rate is low, mid-stem multi-section, without tillers and secondary roots, winter mortality rate. Sowing too much harm, to take measures such as fertilizer and watering, also received no remedial effect, seriously affecting the yield. So sowing of wheat should not be too deep. Weixi Town, West County, West Village is my company’s wheat flourishing base, the implementation of a unified supply, unified seeding, unified tube
