塑料薄膜地面覆盖栽培蔬菜,是一种新的保护栽培法,也是一项重要的土壤管理技术。许多国家已应用于生产,并取得了良好的效果。据石本正一氏报道,薄膜覆盖地面,能起调节地温、防止干燥、提高肥效、防止土壤板结和抑制杂草生长等作用。因而改良了土壤条件,促进作物的生长发育,获得早熟和高产。1979年春我们对塑料薄膜地面覆盖栽培法进行了试验。 Plastic film ground cover cultivation of vegetables, is a new method of conservation cultivation, but also an important soil management technology. Many countries have applied it to production and have achieved good results. According to Shihiro Shimoto’s report, the film covering the ground can play a role in regulating ground temperature, preventing drying, improving fertilizer efficiency, preventing soil compaction and inhibiting the growth of weeds. Thus improving soil conditions, promoting crop growth and development, access to early maturity and high yield. In the spring of 1979, we experimented with plastic film ground cover cultivation.
