根据近几年来的试验和大田调查证明,棉花适时早播,是早熟增产的一个关键措施。早播后的重要问题就是保苗。根据我们沿江地区历年气候记载,春分前后暖流持续时间长;清明到谷雨之间气温变化大,阴雨多,常有寒流出现,这有利于苗期各种病菌繁殖,容易造成严重死苗缺棵现象。1959年我站在培文大队进行了棉花早播保苗一系列试验研究,总结出在做好适时早播的基础上,应抓住播后的十项保苗管理措施,确保苗全、苗齐、苗壮。(1)“松”:未出苗前下雨后,能下地时立即松士,采用浅齿耙,打横直耙,或用松土器松
According to recent years of tests and field surveys prove that timely sowing of cotton timely, is a key measure of early maturity and yield. After sowing the important issue is Paul seedlings. According to the climatic records of the rivers in the past years, the duration of warm current around the vernal equinox is long. The temperature change between Qingming and Guyu is large, and there are many rainy days and frequent cold spells. This is conducive to the multiplication of various germs at the seedling stage, . In 1959, I stood in Peiwen Brigade to carry out a series of experimental studies on early sowing and cotton seedling of cotton and concluded that on the basis of timely early sowing, we should seize the ten seedling management measures after sowing to ensure that all seedlings, Miao Zhuang.
