近年来,随着化学工业的蓬勃发展,塑料的生产和应用日益广泛起来。塑料薄膜用于水稻、地瓜育苗,已取得良好效果。为了扩大冬春蔬菜生产,改善淡季供应,我室于1963年冬——1964年春,进行了塑料薄膜复盖的研究,结果简报如下: 一、研究材料及简要过程: 本试验采用上海生产的聚氯乙烯薄膜。其复盖形式是将薄膜装订在长1.55米、宽0.8米的木框上,阳畦单层复盖,夜间加盖苇毛扇保温。与玻璃阳畦比较。
In recent years, with the vigorous development of the chemical industry, plastic production and application are increasingly widespread. Plastic film for rice, sweet potato nursery, has achieved good results. In order to expand winter and spring vegetable production and improve off-season supply, the study on the plastic film covering was carried out in the winter of 1963 - 1964 in our lab. The results are summarized as follows: I. Materials and Brief Process: Vinyl chloride film. Covering the film in the form of 1.55 meters long, 0.8 meters wide wooden frame, Yang Yang single cover, cover the reed at night with the fan insulation. Comparison with glass yang.
