一般农户都靠经验来估算地膜的用量,往往非多即少。笔者在生产实践中,摸索了一种地膜用量的速算法,使用方便,也比较准确,不妨大家试一试。地膜用量=每亩所需的地膜重量×地膜覆盖率×需要覆盖的面积。因地膜的厚度不同,每亩所需的地膜重量也不一样。地膜厚度与每亩需用地膜重量的对照见下表: Average farmers rely on experience to estimate the amount of plastic film, often non-or less. The author in the production practice, groping a method of calculating the amount of plastic film, easy to use, but also more accurate, may wish to give it a try. Film usage = film weight per mu × film coverage × area to be covered. Due to the different thickness of the film, the weight of the film needed per mu is not the same. Film thickness and acres of film needed to control the weight of the table below:
