To address the issue of soil fertility decline caused by continuous planting of Cunninghamia lanceolata, the current situation of continuous planting artificial forests of Cunninghamia lanceolata and the reasons for soil fertility decline were analyzed, and prevention and sustainable business strategies from aspects such as precise fertilization, implementation of crop rotation cultivation, creation of mixed forests, and strengthening of tending management were proposed. Multi-generation continuous planting of Cunninghamia lanceolata trees can lead to a decline in forest productivity, deterioration of soil pore conditions, field water holding capacity, maximum water holding capacity and other water-holding properties, decreasing the activities of soil enzymes such as soil invertase, urease and protease, and the composition and structure of soil microbial communities change. The imbalance of soil nutrient supply in forest land, self-toxicity of Cunninghamia lanceolata, the toxic effect of aluminum, and unreasonable afforestation measures are the main reasons for the soil fertility decline of continuous planted Cunninghamia lanceolata plantations. Based on this, it is proposed to apply balanced fertilizers according to the growth needs of Cunninghamia lanceolata and increase the application of organic fertilizers. Rotate with leguminous and gramineous crops to balance soil nutrients; improve the community structure of artificial forests and create mixed forests; timely carry out timely tending management, thinning and controlling forest stand density. This article provides a reference for achieving the sustainable development of Cunninghamia lanceolata artificial forests.
