地膜覆盖栽培是通过在单位土地面积上投入较多的生产资料和劳动力,以改变土壤水、热等条件,促进增产、增收,取得较高经济效益的栽培技术。 锦州市1983年试验资料表明,在同样条件下,地膜覆盖栽培的8.8万亩花生,平均亩产612斤,而裸地栽培的花生平均亩产335斤,覆膜比裸地每亩提高82.7％。绥中县荒地乡典型调查,地膜覆盖栽培花生8,500亩,平均亩产780斤;裸地栽培的1,700亩花生,平均亩产450斤,增产率达73.3％。
Film mulching cultivation is a cultivation technique that achieves higher economic benefits through increasing production and labor resources per unit area of land so as to change conditions of soil water and heat, and promote production increase and income increase. Jinzhou 1983 test data show that under the same conditions, the cultivation of 88 acres of plastic mulching, the average yield of 612 pounds, while the peanut cultivation of bare land average yield 335 pounds, the coating film than bare land increased 82.7% . In the typical survey of wasteland in Suizhong County, 8,500 mu of peanuts were mulched and covered with an average yield of 780 kilograms. The 1,700 mu of peanuts cultivated in bare land averaged 450 kilograms of peanuts, yielding an increase rate of 73.3%.
