玉米机械化秸秆粉碎直接还田技术,是用秸秆粉碎机将摘穗后的玉米秸秆就地粉碎,均匀地抛撒在地表,随即耕翻入土,使之腐烂分解,达到大面积培肥地力的一项农机化适用技术。该技术不仅可以大大提高工效,减轻劳动强度,争抢农时,而且将农作物秸秆中含有的氮、磷、钾、镁、钙、硫等多种养分和有机质及时直接翻压还田,可以改善土壤的结构和理化性状,增加有机质含量,促进农作物持续增产增收。
Corn mechanized straw crushed directly into the field of technology, is to use corn stalks grind crushed corn stalks after crushing evenly scattered on the surface, then tillage into the soil, the rot decomposition, to a large area fertility and fertility Agricultural mechanization applicable technology. The technology can not only greatly improve work efficiency, reduce labor intensity, compete for farming time, but also the crop straw containing nitrogen, phosphorus, potassium, magnesium, calcium, sulfur and other nutrients and organic matter in time directly back to the pressure can be improved Soil structure and physical and chemical properties, increase the organic matter content, and promote continuous crop yield increase.
