机械化工艺秸秆切碎还田必须遵照一定的机械化工艺程序来进行,才能达到预期的目的,否则可能出现不良后果。不同的农作物,作业工艺不尽相同。经各地实践总结出的小麦秸秆切碎还田机械化工艺,目前有两种:1.小型割晒机收割(留高茬)→秸秆切碎还田机切碎、抛撒→播种。2.联合收割机收割→秸秆切碎还田机切碎、抛撒→播种。玉米秸秆切碎还田机械化工艺,目前也有两种:1.摘穗→秸秆切碎还田机切碎、抛撒→施肥→旋耕(或耙茬)→深耕→压盖→播种。2.玉米收割机(配切碎还田机)收获,秸讦切碎、抛撒→施肥→旋耕(或耙茬)→深耕→压盖→播种。近几年,有些地区推广夏玉米
Mechanization of straw chopped back to the field must comply with a certain mechanization process to be carried out in order to achieve the desired purpose, otherwise there may be adverse consequences. Different crops, operating processes vary. After the practice concluded that the wheat straw shredded back to the mechanization process, there are two: 1 small windrower harvesting (stay high stubble) → straw shredding machine shredding, throwing → sowing. 2. Combine harvester harvesting → chopped straw chopped machine, throwing → sowing. Corn stalks back to the mechanized mechanization, there are two: 1. Pick the ear → straw chopper reclaimer, throwing → fertilizer → rotary (or stubble) → deep plowing → gland → sowing. 2. Corn harvester (with chopper machine) harvest, straw chopped, throwing → fertilization → rotary (or stubble) → deep plowing → gland → sowing. In recent years, some regions promote summer maize
