| Based on the investigation of soil properties of different afforest plant types which grow on the afforested slopes of Nan-You highway, scientific references are proposed for the afforest management of Nan-You highway. The collected physical and chemical soil samples were tested and studied, and the F-test was applied on dealing with the analytical data, the results showed that the physical features of the soil was bad and the content of the soil nutrient was low. The soil properties of different afforest plant types had significant or extremely significant differences. The properties of the soil which plant Acacia confusa and Tephrosia candida were better than those plant Melinis minutiflora and Wedelia trilobata. More nitrogenous, phosphate and organic fertilizer were suggested, and neutral and alkaline fertilizer were recommended. |
