近几年,为了提高作物产量,农民种田普遍使用地膜,但也有些耕地不适宜盖地膜,概括起来有以下五种田:一、纯旱田。除雨季外,长期干旱的耕地盖地膜不仅起不到应有的作用,而且会加重旱情。二、沙土田。沙土地盖地膜,中午地面温度过高,尤其是在干旱的情况下,对作物反而有害。三、粘 In recent years, in order to improve crop yields, farmers commonly use plastic film farming, but also some cultivated land unsuitable for cover film, summed up the following five fields: First, pure dry land. In addition to the rainy season, long-arid cultivated land cover film not only failed to play its due role, but also aggravate the drought. Second, sandy soil.
