塑料薄膜地面覆盖栽培是目前正在推广的一项农业新技术。由于地膜覆盖后,栽培环境条件发生了一系列变化,减少土壤水分蒸发,增加光照强度,提高土壤温度,从而能使作物早熟增产。作物在覆盖条件下,形成了一个良好的生态环境,表现在温度、光照、水分等主要气象条件的显著改善。 Plastic film ground cover cultivation is currently being promoted as a new agricultural technology. After mulching, the environmental conditions of cultivation have undergone a series of changes to reduce soil water evaporation, increase light intensity and increase soil temperature so as to increase the yield of crops. Crops under cover conditions, the formation of a good ecological environment, manifested in the temperature, light, moisture and other major weather conditions significantly improved.
