Abstract:

通过干热河谷银合欢人工林对土壤改良效应5年的研究,结果表明银合欢林具有很好的土壤改良效应,土壤有机质明显高于CK,在0~20cm,20~40cm和40~60cm的土层中,比CK分别高52.61%,51.09%和43.52%,土壤有机质随着土壤深度的增加而减少。pH在0~20cm,20~40cm和40~60cm的土层中,比CK分别低8.28%,2.41%和2.19%。全N含量上层土壤明显高于下层,水解N比CK高43.75%,随着土壤深度的增加,水解N呈现下降趋势,并具有显著性相关关系。全P含量比CK高0.05mg/kg,相差不是很明显。有效P含量与CK相差不是很明显,在不同土层深度有效P含量的变化非常一致。全K含量比CK高0.98mg/kg,银合欢的生长对土壤全K含量的影响并不明显。速效K含量平均为136.79mg/kg,变化幅度较大,比CK高69.45mg/kg,银合欢的生长对土壤速效K含量的影响明显。
