| In order to understand the Litchi orchard soil nutrient status, collecting 29 representative soil samples in Central and West Hainan Litchi plantations to evaluate the soil nutrient fertility status. Compare with the 29 soil samples of The Second Soil Survey of Hainan province. The results indicated that the contents of soil organic matter, total nitrogen, available nitrogen, available phosphorus, and available potassium were relatively low, but available calcium and availability magnesium were very high. The contents of micro-elements such as available iron, available manganese and available zinc were relatively high. The distribution of soil contents was mainly determined by the orchard landform and management system. |
