棉花缺苗断垄的原因是很复杂的,也是各地普遍存在而且相当严重的问题,由于缺苗断垄现象的存在,就意味着产量的减低。据1956年在河南西华县五二农场的调查材料来看,一般达15—20%,严重的达45.6%;同年在河南修武县新河农场调查,缺苗断垄严重者高达50%左右;据我场二中队三年(1956—1958年)的调查记载资料,按每亩棉田5,407株作为全苗,平均亩产籽棉556.7斤,那么,4,512株的,亩产仅307.12斤,3,796株的亩产只有286.5斤;再者,据我场一中队1957—1958年的典型调查,棉田缺苗12.7%
The reason for the lack of cotton seedlings for breaking the ridge is very complicated, and it is also a problem that is ubiquitous and quite serious all over the country. Due to the lack of seedlings and the breaking of the ridge, it means that the yield is reduced. According to the survey materials of 51 Farms in Xihua County in Henan Province in 1956, the average amount is 15-20% and the rate is 45.6%. In the same year, in Xinhe Farm, Xiuwu County, Henan Province, 50% According to the investigation records of the second Squadron of our field for three years (1956-1958), 5,407 cotton plants per acre were used as whole seedlings, with an average of 556.7 kg of seed cotton per mu per acre. As a result, the output of 4,512 strains was only 307.12 kg per mu and 3,796 mu In addition, according to a typical survey of a field squadron from 1957 to 1958, cotton seedlings lacked 12.7%
