塑料薄膜地面覆盖(以下简称地膜覆盖),是近年来国内外农业生产上迅速发展的一项新技术,对蔬菜生产有明显的早熟增产效果。根据我国各地试验,一般增产20—30%,早期产量提高30—40%,甚甚1～2倍;提早成熟10天左右;品质好,病害轻,而且免耕、省水。1979年我区呼市、集宁15个点试验,也取得了同样效果。地膜覆盖早熟增
Plastic film ground cover (hereinafter referred to as plastic film cover) is a new technology developed rapidly in domestic and foreign agricultural production in recent years, and has obvious precocious yield increase effect on vegetable production. According to the tests in various parts of China, the general increase of 20-30%, early production increased by 30-40%, or even 1 to 2 times; early maturity of about 10 days; good quality, disease light, and no-tillage, water conservation. In 1979, my area Hohhot, Jining 15 points test, also made the same effect. Plastic film covered by premature
