农业将使用有孔地膜研究表明，采用有孔地膜覆盖作物有以下优点：调节膜内温度膜内最高温度比普遍地膜降低３～８℃；土壤５厘米深处清晨最低温度可提高０５～２℃，从而可减轻覆膜后的高温危害。提高早春防寒效果覆有孔地膜，土壤水分可向膜外散发水蒸气，使接近地面的... Studies on the use of perforated mulches in agriculture show that the use of perforated mulching has the following advantages: The highest temperature in the membrane is regulated by 3 to 8 [deg.] C. lower than the prevailing film; the minimum temperature in the morning at 5 cm can be increased by 0,5% 2 ℃, which can reduce the high temperature damage after coating. Improve the effect of cold in early spring covered with a hole in the film, soil moisture can be distributed to the membrane outside the water vapor, so close to the ground ...
