国营农场运用地膜植棉新技术,是从新疆石河子垦区开始的。1980年试种7亩地膜棉花,获得了平均亩产200斤皮棉的好收成。1981年扩大到10个垦区2万亩,平均亩产157斤皮棉,比露地棉花增产40～60%;其中农八师15000亩平均亩利润113.88元,比露地棉花多收益38元。去年新疆生产建设兵团地膜棉花面积又进一步扩大,达47万亩,占棉花总播面积的26.4%。江苏、陕西等地的一些农场的地膜棉花也取得了较好的经济效果,显示了地膜栽培新技术的生命力。据不完全统计,去年国营农场地膜植棉面积达48万亩,占农垦棉花面积的
State-owned farms use of plastic filming cotton new technology, is from Shihezi reclamation area in Xinjiang began. In 1980, 7 mu of plastic film cotton was planted and a good yield of 200 kg of lint per mu was obtained. In 1981, it expanded to 20000 mu of 10 reclamation areas, with an average of 157 kg lint per mu, 40-60% more than that of open field cotton. The average acreage of 15000 mu of Nongbashi division was 113.88 yuan, 38 yuan more than that of open field cotton. Last year, Xinjiang Production and Construction Corps cotton mulching area has further expanded to 47 million mu, accounting for 26.4% of the total sowing area of cotton. Film mulching on some farms in Jiangsu, Shaanxi and other places also achieved good economic results, demonstrating the vitality of new technologies for film mulching cultivation. According to incomplete statistics, last year state-run farms covered 48 million mu of cotton, accounting for the area of cotton fields
