棉花生产田间管理复杂,工序繁多,急需实现部分作业的机械化操作。一、目前有70％的作业可以机械化 1975年我们在临猗县冯家卓大队100亩棉田上进行试验,播种、中耕、施肥、培土四项作业机械化操作;1978年在运城县上王大队300亩棉田上试验,用机械搞了三项作业:播种、中耕、施肥;1979年在冯家卓500亩棉田上试验,播种、中耕、施肥、治虫四项作业全部机械化,没有用人畜力,效果很好,工效提高10-20倍。有人耽心,拖拉机悬挂农具在棉田行走,会不会损伤棉苗。我们也作了检查,在一块水地棉田,行距60厘米,7月30日平均株高60厘米、果枝9个、大棉桃6.6个、花6个、蕾16.8个,用
Cotton production field management complex, many processes, the urgent need to achieve part of the mechanized operation. First, there are currently 70% of operations can be mechanized In 1975, we Linli County Fengjiazhu brigade 100 acres of cotton field trials, sowing, cultivation, fertilization, earthwork four operations mechanization operation; in 1978 in Yuncheng County Wang brigade 300 acres of cotton In 1979, Feng Zhenzhuo 500 acres of cotton field trial, sowing, cultivating, fertilization, pest control four operations all mechanized, no human and animal husbandry, the effect is very good, work efficiency increased 10-20 times. Some people are worried that tractors flying agricultural tools walking in the cotton field, will not damage cotton seedlings. We also checked that in a paddy field of cotton water, the spacing was 60 cm. The average height of plant on the 30 July was 60 cm. There were 9 fruit branches, 6.6 large flowers, 6 flowers and 16.8 buds.
