近年来在我省棉花丰产实践中,涌现了一批亩产皮棉200斤的社队,科研单位也多年进行了亩产皮棉200斤的栽培研究,为提高棉花单产树立了样板,积累了经验。为了迅速大幅度提高亩产,促进棉花大上快上,今年要求有更多的社队皮棉亩产上“双纲”。我们曾在本所和天门、沔阳等农村基点先后进行了亩产皮棉200斤以上棉株生育进程、群体结构和主要栽培技术的试验研究和调查总结。根据6年15次试验结果,18.5亩棉田,平均亩产皮棉209.22斤,10月20日以前收花量达到80—99.17％;平均实收密度为每亩 In recent years, cotton yield in our province practice, there emerged a group of 200 kg per mu lint of community units, scientific research units for many years also carried out 200 kg per mu lint cultivation studies to improve cotton yield set a model and accumulated experience. In order to rapidly and substantially increase the yield per acre and to promote the rapid development of cotton, more and more forestry lint mu produce on this year is required to be “double-planted.” We have carried out pilot studies and survey conclusions on the fertility process, population structure and main cultivation techniques of over 200 pounds of lint per mu in the rural areas such as Tianmen and Shenyang. According to 6 years of 15 test results, 18.5 acres of cotton fields, the average yield of lint 209.22 kg, October 20 before the amount of flowers received 80-99.17%; the average real density for the acquisition of acre
