水稻秸秆还田对控制环境污染、改善土壤理化性状、提高地力有着积极意义,但也出现了部分秸秆还田口块小麦出苗差,冬春冻害严重等现象。为解决此类问题,在广泛调查的基础上,总结了一套提高秸秆还田质量、促进小麦全苗壮苗的“一碎四增”技术,即切碎秸秆、增加旋耕深度、增加播种量、增施速效氮肥、增加土壤镇压工序,以供参考。
Rice straw return to the control of environmental pollution, improve the physical and chemical properties of the soil, improve soil fertility has a positive meaning, but also appeared in some straw back to the mouth of poor emergence of wheat, winter and spring frost damage and so on. In order to solve such problems, based on extensive investigation, a set of “one crushing and four additions” technology to improve the quality of straw returning and to promote the whole seedling growth of wheat was summarized, that is, chopping straw, increasing the depth of rotary furrow, Increase seeding rate, increasing available nitrogen fertilizer, increase soil repression process for reference.
