我区于1983年开始进行棉花双膜(地膜加营养钵育苗)栽培试验。经过几年的试验、示范和推广,至1986年全区已发展到25万多亩,使我区棉花生产又迈向一个新阶段。一、双膜栽培的优点 1 增产显著据1983—1986年全区34点次不同种植方式对比试验结果,双膜栽培亩产皮棉88.6—120.5公斤,平均98.2公斤;直播地膜覆盖亩产皮棉80.7—105.5公斤,平均88.7公斤;营养钵育苗移栽亩产皮棉76.8—92.5公斤,平均84.6公斤;直播亩产皮棉52.6—89.4公斤。平均75.2公斤。双膜栽培平均比直播地膜覆盖、营养钵育苗移栽和直播分别增产10.7％、16.1％和30.6％。 2.皮棉品质好双膜栽培棉花烂桃
My district began in 1983 cotton double membrane (plastic film plus nutrition bowl nursery) cultivation experiments. After several years of experiments, demonstrations and promotion, the whole region has grown to more than 250,000 mu by 1986, bringing cotton production in our region to a new stage. First, the advantages of a double-film cultivation 1 significant increase According to the 1983-1986 region 34 points different planting methods comparison test results, double film cultivation of lint per mu 88.6-120.5 kg, an average of 98.2 kg; direct seeding mulch cover 80.7- 105.5 kg, an average of 88.7 kg; nutrition bowl seedling transplanting per mu lint 76.8-92.5 kg, an average of 84.6 kg; live mu produce lint 52.6-89.4 kg. Average 75.2 kg. Compared with the direct film mulching, the double film mulching increased the yield by 10.7%, 16.1% and 30.6% respectively in the transplanting and direct seeding of the nutrient bowl. 2.
