| Abstract: | The annual variation in the contents of N, P, K. Ca and Mg in the leaves of litchi, and the annual variation in the contents of available major nutrient elements and in pH of the orchard soils in Zengcheng, Guangdong have been studied in this paper. By statistical analysis, this paper preliminarily finds out the variation pattern and characteristics of the elements in leaves, and the tendency of annual variation in the contents of soil available nutrients and in pH; and analyses the correlation between the annual variation of leaves and the annual variation of soil. |
