不同种植模式紫色土斥水性变化特征
Variation Characteristics of Soil Water Repellency under Different Planting Patterns in Purple Soil
摘要
Abstract
[Objective]This study aims to investigate the variation characteristics of soil water repellency(SWR)and its influencing factors under different planting patterns in purple soil.[Methods]Four planting patterns were established:no planting,CK;Vicia faba Linn,A;Zanthoxylum armatum var.novemfolius,F;and Vicia faba Linn+Zanthoxylum armatum var.novemfolius,AF.The differences in SWR and soil physicochemical properties under different planting patterns and soil layers(0-10,and 10-20 cm)were analyzed.[Results]1)Soil under the CK and A patterns were hydrophilic,while soil under the F and AF patterns were slightly water-repellent.The water drop penetration time(WDPT)under the AF pattern was significantly higher than that in the CK,A,and F patterns by 495％,432％,and 128％,respectively(p＜0.05).2)Different planting patterns significantly affected soil physicochemical properties.In the 0-10 cm soil layer,soil organic carbon,total nitrogen,total phosphorus,and field water holding capacity under the AF pattern were significantly higher than those under the other three patterns(p＜0.05).3)SWR was significantly negatively correlated with bulk density(p＜0.05),and significantly positively correlated with total porosity,field water holding capacity,and alkaline hydrolyzable nitrogen(p＜0.05).Soil organic carbon was significantly positively correlated with total nitrogen and alkaline hydrolyzable nitrogen(p＜0.01).Stepwise regression analysis indicated that soil water repellency was linearly and significantly positively correlated with alkaline hydrolyzable nitrogen(p＜0.01).The agroforestry patrern enhanced SWR while improving soil water retention capacity and soil nutrient levels.[Conclusion]The findings provide a scientific basis for the optimization of agroforestry planting patterns in purple soil regions.关键词
