The red soil distribution area has superior climatic conditions, sufficient light and heat, and long growing period, which is suitable for developing subtropical cash crops, fruit trees and trees, and crops can be harvested 2-3 times a year. Land has great production potential. In China, the red soil area is the main producing area of rice, tea, silk and sugarcane, and the mountainous area is also suitable for planting economic trees such as fir, tung tree, citrus, bamboo and palm. The strong acidity and high viscosity of red soil are unfavorable factors for the utilization of red soil. Applying more organic fertilizer, applying proper amount of lime and supplementing phosphate fertilizer can improve the fertility of red soil and prevent soil erosion. If I live in Gannan, I will grow many kinds of camellia oleifera, tea tree, navel orange and bamboo.
