Abstract:
Abstract:Taking local characteristics of Hezhang Walnut trees and Guizhou Pinellia ternata as materials,by intercropping and comparing pH value，organic matter，total nitrogen，nitrogen，phosphorus，potassium among the middle of two rows of walnut trees(measured points)，the underneath of walnut tree crown (crown next point) and the outside of walnut canopy(outside crown point) and the net for (CK) pinellia soil，analyses the soil nutrient status of Hezhang walnut intercropping with pinellia ternata.The results showed that,the relationship between soil pH value was net for (CK)>crown outer point>measured point>crown next point.The contents of soil total nitrogen and alkali-hydrolyzale nitrogen were both up to grade Ⅱ level which could provide ample protection of nitrogen for the growth of two kinds of nitrogen plant Pinellia and Walnut .The soil organic matter，total nitrogen，phosphorus，and potassium was the highest level at crown under the point，the content of alkali-hydrolyzale nitrogen was the lowest at measured points，and the lowest nutrient content was the control group.Soil pH value was negatively correlated with organic matter，total nitrogen，phosphorus meanwhile it waspositively correlated with K but not significant；between organic matter and other nutrients were positively correlated with the total nitrogen content，especially for the remarkably significant positive correlation ( P =0.871 **)；nitrogen and phosphorus negative correlation was not significantly，and K was a significant reverse correlation ( P =-0.733 *).
