Correlait on between Sarcandra Glabra Biomass and Soil Physical-che mical Properties under Different Interplan-ting Pattern
We studied the correlation between Sarcandra Glabra biomass and soil physical chemical properties under different in-terplanting pattern in Cunninghamia lanceolata of different slope positions.The results showed that: ①Interplanting can improve the soil physical and chemical properties.Soil water content and soil porosity increased, while soil bulk density de-creased;Soil organic matter, total N, total P, available N , available P and available K contents increased by 27.19%, 14.78%, 8.91%, 23.11%, 29.45%, and 11.33%, respectively, but total K decreased by 2.69%.②Compared with the bottom of the slope,the soil water content , bulk density, porosity, organic matter, total P, available N and available K in the top of the slope increased by17 .41%, 1.87%, 4.29%, 4.74%, 4.43%, 9.07%and 6.80%, respectively, while total N, total K and available P decreased by 8.07%, 0.17%and 31.28%, respectively.③Compared with the bottom of the slope, the aboveground biomass, underground biomass and total biomass of Sarcandra Glabra in the top of the slope in-creased by 27.48%, 27.48%and 27.48%, respectively.④There was significantly positive correlation between the soil bulk density, available N, available K and the biomass of Sarcandra Glabra, and significantly negative correlation between total N, available P and the biomass of Sarcandra Glabra.
