| 摘 要： | 通过在辽西半干旱地区不同类型矸石废弃地对上进行不同树种造林试验,结果表明,在Ⅰ类矸石废弃地上,紫穗槐、锦鸡儿在改善全氮、全磷、速效氮、速效磷方面较其他树种差异性显著,白榆在改善全氮方面较显著;在Ⅱ类类矸石废弃地上,白榆、刺槐对于速效氮改善差异性显著,紫穗槐、锦鸡儿在改善全氮、全磷、速效磷方面较其他树种差异性显著,紫穗槐、锦鸡儿在改善速效氮差异性极显著,白榆在改善全氮方面较显著;在Ⅲ类矸石废弃地上,臭椿、火炬树在改善全氮、全磷、速效氮、速效磷方面较其他树种差异性显著,刺槐在改善全磷、速效氮方面较显著;在Ⅳ类地区的矸石废弃地上,火炬树、刺槐、臭椿在改良土壤养分状况方面较之其他树种差异性显著。

| Abstract: | Afforestation experiments with different tree species were conducted on different types of gangue in semiarid regions in western Liaoning Province.Result shows that: in gangue wasteland within class I,compared to other species,Amorpha fruticosa,Caragna fruten have significant differences in improving total N,total P,available N,available P;Ulmus pumila improved total N more significantly;in gangue wasteland within class Ⅱ,Ulmus pumila,Robinia pseudoacacia have significant differences in improving available N.Compared to other species,Amorpha fruticosa,Caragna fruten have significant differences in improving total N,total P,available P;Amorpha fruticosa,Caragna fruten have very significant differences in improving available N;Ulmus pumila have more significant differences in improving total N;in gangue wasteland within class Ⅲ,Ailanthus altissima,Rhus typhina have significant differences in improving total N,total P,available N,available P than other species.Robinia pseudoacacia have significant differences in improving total P,available N;in gangue wasteland within class Ⅳ,compared to other species,Rhus typhina,Robinia pseudoacacia & Ailanthus altissima have significant differences in improving soil nutrient status. |
