地膜覆盖具有提高地温、加速作物生长 发育、增加产量等效应,对此已有大量的报 道。根据试验结果,本文试图对地膜覆盖的 地积温效应及其在蔬菜生产中的应用作一初 步的探讨。 材料与方法 一、试验材料 1.供试地膜。无色透明膜,厚0.015毫 米,幅宽1.6米,由湖南省塑料研究所供给。 Mulching has the effect of raising ground temperature, accelerating the growth and development of crops, and increasing the yield. It has been widely reported. According to the test results, this paper attempts to make a tentative discussion on the geothermal effect of plastic film mulching and its application in vegetable production. Materials and methods First, the test material 1 for the test film. Colorless transparent film, thickness 0.015 mm, width 1.6 m, supplied by the Hunan Institute of Plastics.
