1982年中国农业工程研究设计院和中国农科院蔬菜所,在8米跨的薄壁镀锌钢管装配式塑料大棚内,进行了用地膜覆盖提高蕃茄品质的尝试。他们用0.015毫米的聚乙烯塑料薄膜为地面覆盖材料,用丽春(77—462)品种的蕃茄进行10～15厘米的小高畦栽培。1月10日播种、2月5日分苗、3月17日定植、密度为4000株/亩。每株留果3～4穗。经对不同穗位的蕃茄的测定,发现地膜覆盖这项措施可以提高蕃茄的品质。可使影响蕃茄品质的主要指标——可溶性固形物、含糖量、维生素C、有机酸等的含量提高。(见下表)
1982 China Agricultural Engineering Research and Design Institute and the Chinese Academy of Agricultural Sciences, vegetable, 8 meters across the thin-walled galvanized steel pipe-mounted plastic greenhouse, the use of plastic film mulching to improve the quality of the attempt. Using 0.015 mm polyethylene plastic film as floor coverings, they cultivated 10 to 15 cm of Tamarindus indica with a variety of tomatoes from Lilian (77-462). January 10 sowing, February 5 seedlings, March 17 planting density of 4000 plants / mu. Per plant leaves 3 to 4 spike. After the determination of different ears of tomato, found that the measures to cover the mulching can improve the quality of tomatoes. Can affect the quality of tomatoes, the main indicators - soluble solids, sugar content, vitamin C, organic acids and other content increased. (See table below)
