华北历年来棉花缺苗达15—20%,缺苗的主要原因之一是缺少适用的播种工具或根本就没有播种的工具可用,以致操作粗放,深浅不一致,稀稠不均匀,播浅的被风吹干,播深的芽被闷死。因此改进播种工具以提高播种技术争取全苗密植,是十分重要的。一就农民原有旧楼略加修改补充,达到改进质量,提高效率,人畜省力的棉花播种工具。我国广大农民,历来对用楼有丰富经验, In North China, the number of cotton seedlings has reached 15-20% over the years. One of the major reasons for the lack of seedlings is the lack of suitable sowing tools or tools that are not sown at all. As a result, extensive and inconsistent operations, uneven thicknesses and shallow sowing Dry wind, sowing the bud was suffocated. Therefore, it is very important to improve the sowing tools in order to improve the sowing technology for all seedlings. As soon as the peasants’ existing old buildings were slightly modified and supplemented, the cotton sowing tools for improving quality, improving efficiency, and saving human and material resources were achieved. The vast majority of peasants in our country have always had rich experience in using buildings.
