| 摘 要： | 本文研究了黄河三角洲滨海盐碱区不同树种的刺槐混交林林地的土壤化学性质、土壤酶活性。结果表明:混交林有机质、速效N含量均高于刺槐纯林,速效P、K5-20cm土层中混交林普遍低于刺槐纯林,20-40cmP、K含量高于刺槐纯林;混交林对某种微量元素的改善具有显著的作用;明显改善了土壤主要酶活性;刺槐×白蜡混交效益优于刺槐×臭椿优于刺槐×国槐。

| Abstract: | In saline-alkali soil of coastal district of Yellow River Delta,the soil chemical property and soil en- zyme activity on mixed stands of black locust with different tree species are studied in this paper.The result shows:That organic matter and available N content of mixed stands are higher than that of the pure black locust stand.Available P,K in 5-20cm soil layer of mixed stands are generally lower than that of the pure black lo- cust stand and available P,K content of 20-40cm soil layer are higher than that of the pure black locust stand. Mixed stands have significantly improved soil main enzyme activity.Mixed stands can significantly improve some microelements.The benefit of Robinia pseudoaca L.x Fraxinnus chinensisRoxb,is superior to Robinia pseud- oaca L.x Sophora japonica L.and the benefit of Robinia pseudoaca L.x Sophora japonica L.is superior to Ro- binia pseudoaca L.x Ailanthus altissima Swingle. |
