概况塑料薄膜地面复盖栽培技术,世界上一些工业发达国家1965年开始研究,1970年大而积生产应用。我国是1978年开始这项栽培技术的研究。首先在东北、华北、西北三个地区进行试验。通过三年来的试验,示范实验证明,塑料薄膜地面复盖蔬菜,是一项成本低(与其它保护地栽培设施比较)简便易行,增产增收效果大,深受农民欢迎的一项新技术。因此,几年来发展甚为迅速。全国仅从1979年到1980年的两年时间,由600亩增至25,000余
Overview plastic film covering the ground cultivation techniques, some of the world’s industrialized countries began to study in 1965, in 1970, large production and application. Our country started the study of cultivation techniques in 1978. First in the northeast, north, northwest three areas for testing. After three years of experiments, demonstration experiments show that the plastic film covered with vegetables on the ground is a new technology with low cost (compared with other protected cultivation facilities) that is simple and easy to be implemented, large in yield and income, and welcomed by farmers. Therefore, the development has been very rapid in recent years. The country only increased from 600 mu to more than 25,000 in two years from 1979 to 1980
