4QW-1200型秸秆还田机设计

Design of 4QW - 1200 Type Straw Returning Machine

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。

Maize straw crushing and returning to field is an application technology of agricultural mechanization that uses straw pulverizer to pulverize straw of corn picker,throw in the ground,plough and decompose,so that the soil is fertile.Efficiency was improved,labour intensity was reduced,time availability was advanced after using this technology.Much organic matter and nutritional content of maize straw such as Nitrogen,Phosphorus,Kalium,Magnesium,Calcium and Sulfur could improve soil structure and physicochemical properties,increase content of organic matter and promote sustainable yield of crops.
