| 摘 要： | 采用覆膜措施在辽河三角洲腹地原地土壤修筑台田造林试验,结果表明:覆盖地膜能有效改善土壤理化性状,提高土壤孔隙度,降低土壤容重,改善土壤通透性,提高土壤养分含量,覆膜措施使小胡杨保存率高达92%,增加了0~40cm土层的孔隙度,提高了0~60cm土层的最大持水量,为小胡杨树木生长提供了良好的立地条件。

| Abstract: | Experiments of planting on mound with original soil in Liaohe Delta were conducted by adopting plastic-film-mulching measures.Result shows that the plastic-film-mulching can effectively improve soil physical and chemical properties, improve soil porosity, reduce soil bulk density, improve soil permeability, and improve the soil nutrient content.The plastic-film-mulching measures can make the preservation rate of Populus simonii × P.euphratica being 92%, increase the porosity at 0-40 cm soil layer, increase the maximum water holding capacity at 0-60 cm soil layer, which provides optimal site condition for growth of Populus simonii × P.euphratica. |
