北京市十八里店公社地势低洼,6月中旬以后多雨易涝,稻麦两茬亩产千斤左右,比上茬种小麦、下茬种晚玉米能大幅度增产,因此稻麦两熟面积逐年扩大,1977年全公社1.2万亩粮田中,稻麦两茬面积就占1万亩。为了保农时,促增产,改善劳动生产条件,从1975年起公社党委决定采用机械插秧,开始使用2台机动插秧机和10台人力插秧机插秧,可是机器插的秧苗,缺棵断垅,还经常出现漂秧、勾秧,伤秧等现象,加之机动插秧机常陷车,不如手插秧质量好,速度快。为什么会出现这些问题呢?通过两年实践认识
Shibalidian commune in Beijing low-lying, rainy and prone to floods after mid-June, rice and wheat stubble about two acres, than the previous crop of wheat, the next crop of late corn can greatly increase production, so rice and wheat area by year Expand in 1977, the whole community 12000 acres of grain, wheat and two stubble area accounts for 1 million mu. In order to protect the agricultural sector, boosting production and improving labor and production conditions, the commune and communist party committees decided to adopt mechanical transplanting since 1975, started using 2 mobile transplanters and 10 human transplanters to transplanting rice seedlings. However, Often appear drift seedling, hook seedlings, injury seedling and other phenomena, coupled with mobile transplanter often trapped car, not as good as the quality of hand seedlings, fast. Why do these problems arise? Through two years of practical understanding
