滨海盐土意杨生长障碍因子初步分析

A Preliminary Analysis on the Obstructive Factors to the Growth of ltalian Poplar on Seashore Saline Soil

通过初步调查分析,意杨(Populus×euramericana spp.)在滨海盐土上生长的主要障碍因子是可溶盐浓度、地下水位及土壤酸碱反应,初步提出了意杨正常生长的以上三种土壤性质的适宜范围以及防治措施,可供沿海防护林营造时参考。

Through primary survey and analysis, it has been found that the main obstructive factors to Italian poplar (Populus× euramericana spp. ) growing on seashore salinesoil are the concentration of soluble salt, underground water level and the reaction of soilacid and alkali. The suitable range of the above three soil properties in which Italian poplarcan grow normally has been proposed, and the corresponding prevention and contral measureshave been suggested in this paper. This information would be refered during the plantationof coastal protection forest.
