塑料薄膜地面覆盖栽培技术,是用人工的方法控制、调节作物生育的综合性环境条件,有效地改变作物生育进程与生态状况,以达到早熟、高产、优质为目的的一种新的“护根”栽培方法。也是农业环境工程的一个组成方面。塑料薄膜地面覆盖栽培的历史地面覆盖栽培是我们祖先用稻草、马粪、蒿草、沙石等盖于地面达到保水、保肥,提高地温的一种保护性栽培方法。二十世纪中叶,随着高分子化合物的发展,便用极薄的聚乙烯薄膜取代了覆盖物,形成了新型的塑料薄膜地面覆盖技术。日本是研究最 Plastic film ground cover cultivation technology is a manual method to control and adjust the crop’s comprehensive environmental conditions, effectively changing the process of crop growth and ecological conditions in order to achieve precocity, high yield, high quality for the purpose of a new "root nurse Cultivation methods. It is also a component of agricultural environmental engineering. The historical ground cover cultivation of plastic film ground covering cultivation is a protective cultivation method that our ancestors covered the ground with straw, horse manure, wormwood, sand and so on to achieve water retention, fertilizer conservation and ground temperature improvement. In the middle of the twentieth century, with the development of polymer compounds, a very thin polyethylene film was used to replace the cover, forming a new plastic film floor covering technology. Japan is the most studied
