摘要
以鄂棉15号,西玉3号和鄂豆4号为材料,作了覆膜与不覆膜两种种植方式的对比,通过1999～2001年3年的试验,结果表明:地膜覆盖在生育前期能提高土壤温度和保持土壤湿度,在旺盛生育期有降温效应,因而能显著提高作物产量。这一结论为进一步推广地膜覆盖栽培作物提供了农业气象依据。
The experiment was conducted in two different planting patterns (film-covering and non film-covering)with E-15 cotton.West-3 maize,E-4 soybean during 1999～2001. The result showed that film-covering could obviously increase crop yield because it can rise soil temperature in earlier growing stage, but cool down the temperature in blooming stage, and keep soil humidity. The conclusion will provide agro-meteorolgoical basis for popularizing farther crop cultivation with film-covering.
