1981～1983年,我们在海安县仇湖公社湖中三队和八队进行了棉花稳产高产试验.试验地为水稻土,含有机质1.806～1.823%,全N0.088～0.114%,速效N12.0～12.8ppm’全P0.156～0.161%,速效P2～9ppm,属中等偏上肥力,土质粘重.稻棉两熟,复种指数为212.6%.品种为岱宁棉15号.三年的种植面积和皮棉单产:1981年200.2亩,148.02斤;1982年208.5亩,151.29斤;1983年161.23亩,172.8斤.其中1983年有8块田18.84亩单产皮棉200斤以上,最高田块(1.8亩)单产皮棉235.6斤.而每亩棉花成本平均为37.27元,比一般大田低23.2%;每百斤皮棉成本平均为23.79元,比一般大田低48.2%;每亩棉花纯收入平均为263.31元,比一般大田增加39.6%.
From 1981 to 1983, we experimented on the stable and high-yield cotton production in the third and eighth teams of the lake in Wu’an County, Hai’an County.The paddy soil contains 1.806 ~ 1.823% organic matter, N0.088 ~ 0.114% and N12. 0 ~ 12.8ppm ’all P0.156 ~ 0.161%, available P2 ~ 9ppm, is moderate on the upper fertility, soil sticky .Two years of paddy rice, cottonseed index was 212.6% .Dai Ning cotton varieties for 15. Three years Planting area and lint yield: 200.2 mu in 1981, 148.02 kg; 208.5 mu in 1982, 151.29 kg; 161.23 mu in 1983, 172.8 kg of which 1983, 18.84 mu of 18.84 mu of crop lint more than 200 pounds, the highest field (1.8 Mu) lint yield 235.6 kg, while the average cotton cost per acre was 37.27 yuan, 23.2% lower than the average field; per pound lint average cost of 23.79 yuan, 48.2% lower than the average field; cotton net income per acre of 263.31 yuan , 39.6% more than the average field.
