摘要
以鄂棉 1 5号、西玉 3号和鄂豆 4号为材料 ,作了覆膜与不覆膜两种方式的对比种植 ,通过 1 999～ 2 0 0 1年 3a的试验 ,结果表明 :地膜覆盖在作物生育前期能提高土壤温度 ,保持土壤湿度 ,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 and E 4 soybean in 1999～2001.The results showed film covering could obviously increase crop yield because it could rise soil temperature and keep soil humidity in earlier growing stage, and drop soil temperature during healthy growth stage. This finding provided agro meteorological basis for popularizing crop cultivation farther with film covering.
