一九七四年,我们在奉城、徐泾两个公社和院内试验场进行了棉花高密度栽培试验,基本上都获得了成功。院内试验场,麦茬复播面积0.65亩,密度1.4万株,品种丰棉16号,5月26日播种,5月29日出苗,7月2日现蕾,7月30日开花,9月29日吐絮,单株结铃4.8只,每亩总铃数6.79万个,亩产皮棉153.25斤。上海地区五、六月份雨量较多,棉花高密度栽培,在基肥足、前期施肥多的情况下,
In 1974, we carried out high-density cotton cultivation experiments in the communes and in-hospital test stations in Fengcheng and Xujing, and basically all succeeded. In-hospital test field, stubble replanting area 0.65 acres, density 14000, variety cotton 16, sowing May 26, May 29 emergence, budding on July 2, July 30 blossom, September 29 Periwink Tuo, single boll bell 4.8, the total number of bolls per acre 67,900, 153.25 kg of mu produce lint.
