秸杆还田,能增加土壤有机质,培肥地力,提高农作物单产。尤其麦秸还田,易行、见效快。但目前麦秸还田的一般方法是先用缺口耙切耙后再耕翻,或用专用秸杆切碎机作业,这样增加一次机力作业,消耗能源,提高了农业成本。我团场在学习外地改装经验基础上今夏分别在东风—S、南斯拉夫ZMAJ—141、ZMAJ—161三种不同型号的联合收割机上进行改装,在其尾部增加了一套切碎抛撒装置,使秸杆切碎抛撒与收割一次完成,减少了作业层次,降低了成本,经过今年夏收的使用,效果良好,现介绍如下:
Straw back to the soil, can increase soil organic matter, fertilize fertility, improve crop yields. In particular, wheat straw, easy, quick. However, at present, the general method of returning straw to soil is to cut the harrow with a rake and then tillage it, or use a special straw shredder to work. This increases the mechanical work, consumes energy and increases the agricultural cost. On the basis of learning field modification experience, my field was modified on three different types of combine harvesters, Dongfeng-S, Yugoslavia ZMAJ-141 and ZMAJ-161 respectively in the summer of this year. A shredding and scattering device was added to the tail to make straw Shredding and harvesting of chopped stems are completed in one go, reducing the operating level and cost. After the summer harvest this year, the effect is good and the presentations are as follows:
