[目的] 为了研究土壤磷肥和盐分及其交互作用对紫花苜蓿生长、磷营养和耐盐性的影响。[方法] 通过向[XC;% 102% 102]土中添加不同浓度梯度的磷肥(0,40,80,160 mg/kg,以KH2PO4的形式添加)和氯化钠(0,0.4,0.8,1.6 g/kg)进行温室盆栽试验,种植紫花苜蓿"甘农七号"。[结果] 紫花苜蓿地上部生物量和地下部生物量均随着磷肥施加水平的提高而增加,但随着盐分添加水平的提高而减少;施磷时植物的磷吸收量增加,当磷水平为160 mg/kg时,根、茎、叶的磷含量均达到最大 ...

以四川盆地西缘中低山坡地为研究样地,根据实际地貌特征分别选取3个典型山体、2个典型土壤类型。山体坡面不同坡位下土壤质量综合指数(PI)研究表明土壤质量指数随山体坡面位置相对海拔高度的降低而增高。不同利用方式下土壤质量综合指数(QI)研究表明,人工林的土壤质量指数值显著偏高,坡耕地的指数值最低。中低山坡地土壤质量的变化特征主要依赖于土地利用与覆盖之间的差异。故必须加强坡耕地规范治理,实施植被保护与重建等一系列土壤资源持续利用措施,实现土壤质量的持续健康发展。
