山东省小麦玉米两作区玉米秸秆粉碎直接还田面积已达90%~95%,大部分麦田为玉米秸秆还田后旋耕播种,这导致耕作层松悬等四大隐患,是造成10多年来小麦播种量被迫大幅度增加,既浪费种子又加重后期倒伏的最主要原因。利用镇压机秋种镇压,沉实耕层,破碎坷垃,控制跑墒,加大提墒,确保播种层墒情,从源头上可一次性有效解决四大隐患。
In Shandong Province, two areas of wheat and corn corn stalks directly back to the area of crushed reached 90% ~ 95%, most of the corn stalks for the rotary sowing of corn stalks, which led to tillage loose layer of the four major hidden dangers is caused more than 10 years Wheat sowing volume was forced to increase substantially, both the seeds of waste and aggravating the main reason for late lodging. Autumn suppression of the use of the suppression of cracks, deep plowing, broken Kechuan, control running moisture, increase soil moisture, to ensure moisture sowing layer, from the source can be one-time effective solution to the four hidden dangers.
