棉花地膜复盖栽培技术,是我市万亩高产攻关试验中引进、试验、示范、推广的新技术。1982年试验面积24亩,中晚熟品种鲁棉二号结桃多,桃子大,成熟早,产量高。1983年推广面积1171亩,平均增收皮棉41.6斤。1984年全试区复盖3398亩并进行了棉花地膜复盖小气候效应的对比观测试验。实践证明:棉花地膜复盖,改善了棉田小气候条件,具有明显的增温、增湿作用,不但是高产再高产的有效措施,而且是中产变高产的新途径。 Cotton film mulching cultivation techniques, is the city’s mu high yield test in the introduction, testing, demonstration, promotion of new technologies. 1982 test area of ​​24 acres, middle-late-maturing varieties Lu Mian two more peaches, peaches large, mature early, high yield. In 1983 to promote an area of ​​1171 acres, an average increase of 41.6 pounds of lint. In 1984, the entire test area covered 3398 mu and compared the microclimate effects of cotton mulching. It has been proved that cotton mulching can improve the microclimate conditions in cotton field and has obvious warming and humidifying effects. It is not only an effective measure for high yield and high yield, but also a new way for high yield of middle class.
