一种可取代普通地膜的新型渗水地膜,由山西省农科院综考所副研究员姚建发等人研制成功。经山西省及周边省份多点试验和大而积应用示范证实,应用渗水地膜比普通地膜贸盖的农作物增产百分之二十以上。我国半干旱地区小于十毫米的降水发生率在百分之七十以上,普通地膜因不具通透性,膜上的降雨
A new type of water-permeable plastic film that can replace ordinary film was successfully developed by Yao Jianfa, an associate researcher at the Comprehensive Institute of Shanxi Academy of Agricultural Sciences. The Shanxi Province and the neighboring provinces by more tests and large-scale application demonstration confirmed that the application of water-permeable plastic film mulch than the average increase of more than 20% of crop production. The incidence of precipitation less than 10 mm in semi-arid area of China is more than 70%. Ordinary mulch film is not permeable, rainfall on the film
