1990—1994年,我所承担了全国农业技术推广总站和中国农用塑料应用技术学会下达的新型棚膜试验,先后对国内22个厂家生产的7种新型棚膜的性能进行观测比较和示范应用.结果表明,这些新型棚膜的耐老化性、保温性、透光性或流滴性均明显好于聚乙烯普通膜,在以塑料大棚和日光温室为主的蔬菜设施栽培中有着广阔的应用前景。
From 1990 to 1994, I undertook a new type of greenhouse film test which was issued by China National Agricultural Technology Extension Station and China Society of Agricultural Plastics Technology and Technology, and observed and compared the performance of seven kinds of new type of greenhouse films produced by 22 domestic manufacturers. The results showed that these new type of greenhouse film had better aging resistance, heat preservation, light transmittance or drip flow than ordinary polyethylene film, and had broad application prospects in the cultivation of vegetable facilities mainly in plastic greenhouse and solar greenhouse .
