过去人们习惯把棉花精细整枝当作增产的主要环节,要进行脱裤腿、抹赘芽、打顶心、打边心、剪空枝、打老叶等多道工序,有的工序还要重复几次,费工多、劳动强度大。在河南省农林科学院主持下,我们参加了47个单位的协作攻关,进行了棉花不整枝试验,通过改进其他栽培措施,免去整枝的全部内容。经四年59点次试验,546个比较数据表明,不整枝的不投工、不投资,棉花并不减产。此项研究获河南省1983年重大科技成果奖。1982年全省推广面积达500余万亩,节省劳力总值约4,000万元。与其相适应的栽培技术主要有如下几点:
In the past people used to fine cotton pruning as the main part of the increase, to take off the legs, wipe buds, Top Top, Beidianxin, cut empty branches, playing old leaves and other multi-channel processes, and some processes but also repeat a few Times, more labor, labor intensity. Under the auspices of Henan Academy of Agriculture and Forestry, we participated in 47 units of collaborative research, conducted a cotton pruning test, by improving other cultivation measures, eliminating the entire contents of the pruning. After four years of 59 points test, 546 comparative data show that the pruning does not work, do not invest, cotton is not cut. This research won the Henan Province 1983 major scientific and technological achievement award. In 1982, the province’s promotion of more than 500 acres, saving labor value of about 40 million yuan. The appropriate cultivation techniques are as follows:
