摘要
2005年、2007年将从辽宁引进的大果沙棘种植在西宁市樟脑山。2016年对该地的大果沙棘人工林的生长状况进行了调查,并对林内土壤的理化性质进行分析,以探索大果沙棘人工林对土壤生态效应的影响。结果表明:不同地形中,生长势平地>洼地>坡地;对于理化性质,11年生大果沙棘人工林通透性>9年生,11年生大果沙棘人工林中土壤肥力和养分优于9年生大果沙棘人工林;不同地形中,平地的理化性质优于洼地和坡地,平地更适于大果沙棘生长,更易成林;不同品种中,对于土壤理化性质的影响不明显。因此,选择适宜的种植条件,生长时间越长对于土壤性质改良的效果越好。
Hippophae rhamnoides were planted in Zhangnao Mountain of Xining City from Liaoning Province in2005 and 2007.In 2016,growth vigor was investigated,physical and chemical properties were analyzed,and ecological effect of artificial Hippophae rhamnoides plantation was explored.Result shows that growth vigor is flat land> depression >slope in different terrains.For soil physical and chemical properties,permeability of 11-year-old Hippophae rhamnoides are optimal than that of 9-year-old Hippophae rhamnoides.In different terrains,the physical and chemical properties of flat land are optimal than that of depression and slope,the flat land are more suitable for growing than depression and slope,and more easily being the forest.In different varieties,all of trees varieties affect no significant level to physical and chemical properties.Therefore,the longer grow time of Hippophae rhamnoideslinn,the better improvement effect on the soil properties in suitable condition,optimal planting time should be selected.
