塑料薄膜地面覆盖栽培(简称地膜覆盖栽培),是六十年代兴起的一项栽培保护技术,目前在日本、法国、美国、意大利、西班牙、荷兰、比利时等国已广泛应用于生产,尤以日本发展最快.我国1978年从日本引进这一技术,首先用在蔬菜育苗和栽培上,以后在棉花、水稻育苗方面,在华北、东北、西北试点都取得良好效果.近年来广为群众所采用,但在培育林苗上还少应用报道.为了加速我市林业发展,解决培育大苗壮苗以及难培育树种的育苗技术,我们进行了地膜覆盖培育林苗应用技术和效果的初步试验.
Plastic film ground cover cultivation (referred to as plastic film mulching cultivation), is the rise of the sixties a cultivation and protection technology, at present in Japan, France, the United States, Italy, Spain, the Netherlands, Belgium and other countries have been widely used in production, especially in Japan The fastest growing.China’s introduction of this technology from Japan in 1978, first used in vegetable nursery and cultivation, and later in cotton, rice nursery, in North China, northeast and northwest of the pilot have achieved good results in recent years widely used by the masses , But less applied in the cultivation of forest seedlings reported.In order to accelerate the development of forestry in our city, to solve nurturing strong seedlings and nursery seedling cultivation technology, we conducted a preliminary test of plastic film mulching cultivation techniques and effects.
