地膜覆盖栽培技术,自1978年冬由日本引进以来,在我国经过十几年的试验、示范和推广,其效益和作用是肯定的,并已得到了较大程度的发展,现覆盖面积已达3500万亩左右,跃居世界首位。但目前地膜覆盖栽培也还存在一些问题,表现为: 1.农民缺乏一整套与地膜覆盖栽培相配套的栽培方式及管理技术措施,或者说这一整套栽培技术没有在农民中普及。
Since its introduction in 1978 by Japan in the winter of 1978, the film-mulching cultivation technology has been validated and has gained a considerable degree of development thanks to more than 10 years of experiments, demonstration and popularization in our country. The coverage of the mulch has now reached About 3500 mu, jumped to the top of the world. However, there are still some problems in the mulching cultivation at present, as follows: 1. The peasants lack a complete set of cultivation methods and management technical measures that match the mulching cultivation, or the whole set of cultivation techniques are not popularized among peasants.
