<正>根据泡桐喜温暖、湿润、不耐盐碱的生态习性,1985～1986年在盐渍地上,以种根及平茬根为材料,进行了块状塑料地膜覆盖造林试验。试验结果表明:土壤盖膜后,在增温、保墒、压盐的作用下,可显著提高泡桐造林成活率和高、径生长量;得出了泡桐盖膜造林经济有效的覆盖面积。

According to the it ecological charaters, Paulownia likes temperate climate, humidity and has no resistance to salt. From 1985?986, we used the root-cutting and whole root to test woods on saline soil covered with plastic film. The result showed that the temperature and humidness could be raised and the soil salinity could be reduced. Because of these, significance of the survival rate of plantation, the hight and the diameter increment could be reached. We also get the economical and effective area covered with plastic film for Paulownia’s planting.
