塑料薄膜地面覆盖栽培蔬菜技术,日本从五十年代初期即行研究,在生产上普遍推广后,对于促进蔬菜早熟丰产,具有显著效果。近几年来,我省塑料薄膜拱棚覆盖蔬菜栽培发展迅速,全省城镇郊区覆盖面积达六、七千亩。但未进行地面覆盖,生产潜力未充分发掘.特别是在早春,塑料大棚内温度较低,湿度较大,蔬菜早期定植常遭失败.采用塑膜地面覆盖,具有增温、保水和提高肥效等多方面优点,但使用后经济效果是否合算,怎样使用,使用后对土壤理化性质有何影响等,都还缺
Plastic film covering the cultivation of vegetables on the ground, Japan from the early 1950s that line research, in the general promotion of production, for the promotion of vegetable precocious yield, with significant results. In recent years, our province plastic film arch covered vegetable cultivation has developed rapidly, the province’s suburban area covers an area of six or seven thousand acres. But did not cover the ground, the production potential is not fully explored.Especially in early spring, the temperature inside the plastic greenhouse is low, humidity is high, vegetable colonization often failed early.Using plastic film ground cover, with warming, water retention and improve fertilizer efficiency Many advantages, but after the use of economic efficiency is cost-effective, how to use, after use of the physical and chemical properties of the soil, etc., are still missing
