【摘要】 针对华北平原小麦玉米两熟秸秆还田条件下,普遍存在秸秆还田量大、播种质量不高的问题,以华北平原地区实际工作环境为背景,通过分析目前耕整机械作业的优劣,提出秸秆还田条件下整地机械的作业方案。其主要目的是为了提高秸秆还田量大条件下的播种质量,减少农田作业时拖拉机进地次数,降低耕作成本,为小麦玉米两熟地区整地机械耕作方式提供新的设计思路。更多还原

【Abstract】 In condition of straw returning and Wheat and maize double cropping of the North China Plain,two questions which are the heavy of straw returning and poor seeding quality exist in the farming. The analysis of scarification machine work on actual working environment in the North China plain area. We put forward a new scheme of farming in order to solve the questions of the North China plain by the analysis; it will help farmers to increase the seeding quality and decrease the costing of farming by reducing the times of tractor’s working. It also comes up with a new thinking of wheat-corn tillage.更多还原
