塑料薄膜地面覆盖栽培(简称地膜覆盖栽培)技术,日、法、美等国都已大面积在生产上应用,尤以日本发展最快.我国自1978年起主要集中于高寒的东北地区试行.我省3月底至4月上旬常年气温偏低,土温回升慢,影响茄果、豆类蔬菜及时播种与定植.为此,我所于1980～1981年重点研究春季地膜覆盖栽培茄果、豆类蔬菜的早熟增产效果,摸索在长江以南地区的应用价值与技术.
Plastic film ground cover cultivation (hereinafter referred to as plastic film mulching cultivation) technology, Japan, France, the United States and other countries have large areas of production in the application, especially Japan’s fastest growing since 1978, our country mainly concentrated in the cold northeast pilot. From the end of March to the beginning of April in the province, the perennial temperatures were low and soil temperature rose slowly, affecting timely sowing and planting of eggplant and beans and vegetables.Therefore, in 1980 ~ 1981, Early maturity of vegetables yield effect, explore the application value and technology in the area south of the Yangtze River.
