The Analysis of the Growth and Soil Fertility Variables of Cunninghamia lanceolata Forest with Interplanted Sarcandra glaber Inside

This paper focuses on the state variables of the Cunninghamia lanceolata forest such as growing,shape and properties and soil fertility after interplanting the Sarcandra Glaber in the intermediate cut Cunninghamia lanceolata. The experiment results show that: interplanting Scarcandra glaber in the intermediate cut Cunninghamia lanceolata forest is not only good for the yield, shape and quality of the Cunninghamia lanceolata, but also forming better growing environment for the Scarcandra glaber by improving the soil quality of the forest. The better planting model of Cunninghamia lanceolata forest for nurturing great-diameter-wood and producing compatible non-wood product(the Scarcandra glaber) should adopt the management density of 1050/hm2. Therefore, interplanting Scarcandra glaber in the intermediate cut Cunninghamia lanceolata forest is a good management model.
