一九七八年江心大队六千亩棉花,获得平均亩产皮棉160.2斤的好收成。在高产的基础上,如何保持稳产和更高产?他们从分析近几年棉花产量的变化中,得到了启示。一九七六与一九七八两年的气候条件和棉花生长大体一致,但产量截然不同。一九七六年平均每亩总桃数五万八千个,亩产皮棉只有95斤,原因是桃小铃轻,无效桃多(占总桃数40％上下),一、二级籽棉仅占总产55％;而一九七八年虽然每亩总桃数只有五万三千个,但亩产皮棉反高达160.2斤。原
In 1978, the river center brigade of six thousand acres of cotton, access to an average of 160.2 kg of lint yield a good harvest. On the basis of high yield, how to maintain stable and higher yield? They analyzed the changes of cotton production in recent years and got enlightenment. The climatic conditions in 1976 and 1978 were broadly in line with cotton growth, but the yields were quite different. In 1976, the average peach number per mu was 58,000, with only 95 kg of lint per mu. The reason was that peach bell was light, peach tree was not effective (40% of the total number of peach trees) Accounting for 55% of the total output. In 1978, although the total number of peaches per peasant was only 53,000, the lint yield per mu was as high as 160.2 kg. original
