一、技术原理 在收获小麦时或小麦收获后,将麦秸及根茬直接留于地表或耕翻入土壤中,使其腐解,有效增加土壤有机质、培肥地力,或先将麦秸收获,在冬小麦入冬前进行覆盖,以减少冬麦植株水分散失,提高复活率,同时麦秸腐解后也可以发挥肥料效用。 二、操作过程 1.麦秸机械还田 采用联合收割机加装粉碎机,在小麦收割、脱粒的同时将麦秸粉碎成10cm左右的碎节,抛撒在田 First, the technical principles Harvest wheat or wheat harvest, the wheat straw and stubble directly on the surface or tillage into the soil, its decomposition, effectively increase soil organic matter, fertility, or wheat straw harvest, in the first Winter wheat before winter to cover, in order to reduce winter wheat plant water loss, improve resurrection rate, while decomposing wheat straw can also play a role in fertilizer. Second, the operation process 1 straw machine backyard Combine Harvester installed grinder, wheat harvest, threshing at the same time the straw crushed into pieces about 10cm, thrown in the fields
