摘要
比较了华山松—响叶杨不同比例的混交林和华山松纯林在相同立地条件下的生态效益。结果表明:混交林能充分利用营养空间,有效改善林内小气候,降温增湿作用较明显;提高林地土壤肥力,其中有机质、速效磷、速效钾、pH值比华山松纯林分别高15.99%、10.84%、7.69%、12.50%;同时,也增强了华山松对病虫害的抵抗力。
In this paper, we studied the eco-effect of the mixed forest of P.armandi and P. adenopoda Mazim; and the pure P.armandi forest in same site condition. The mixed forest can improve the eco-effect of the forestry, make use of the nutritional space, decrease the temperature and increase the humility. The organic matter,the available P,the available K, pH of mixed forest were 15.99%, 10.84%, 7.69% and 12.5% more than these of pure P.armandii forest, respectively. The mixed forest can raise the soil nutrition, strengthen the P.armandii＇s resistance to disease and pests.
