地膜覆盖栽培技术是一项通过采用极薄的聚乙烯地膜覆盖土壤表面,达到增温保墒保水,促进种子提早萌发出土,加快植株地下部分和地上部分生长发育,调节植物某一阶段生长发育的持续时间,协调各器官物质分配,并获得早熟、高产、优质、高效的增产技术。我国地膜栽培技术起步较晚,1978年农牧渔业部通过对外科技交流项目,从日本引进地膜覆
Mulching technology is a film covering the soil surface by using ultra-thin polyethylene film to achieve the function of warming and preserving soil moisture, promoting early germination of the seeds, accelerating the growth and development of underground and aboveground parts of plants, and regulating the growth and development of plants at a certain stage Time, coordinate the material distribution of various organs, and access to early maturity, high yield, high quality, efficient stimulation technology. Membrane cultivation technology in China started late, in 1978, Ministry of Agriculture, Animal Husbandry and Fisheries through foreign exchange programs, the introduction of plastic film from Japan
