Abstract

In order to quickly build high-quality Schima superba fire prevention forest belts, this study took Schima superba artificial forest belts as the research object, investigated and statisticed the survival rate, preservation rate, tree height, and breast height diameter of Schima superba forests under different afforestation and nurturing methods, analyzed the impact of different afforestation and nurturing methods on the growth of Schima superba forests, calculated and compares the capital investment of different afforestation and nurturing methods, and provided references for the construction of Schima superba fire prevention forest belts.The results showed that in the year of planting, the survival rate of seedlings under treatment I and treatment II was higher, and the impact was statistically significant (P<0.01). After planting for 3 years, the preservation rate of Schima superba seedlings treated with treatments I and II was higher, and the impact was statistically significant (P<0.01). After 7 years of planting, the diameter at breast height and tree height of Schima superba seedlings under treatments I and II were both higher, with a statistically significant impact (P<0.05). The three afforestation and nurturing methods used the same seedling cost, but the labor and fertilizer costs for treatment I were relatively high. Based on the effects of different afforestation and nurturing methods on the growth of Schima superba forests, treatment II was more suitable for creating a fire prevention forest belt for Schima superba, which involved comprehensively cutting off mixed irrigation and block shoveling grass without leaving coniferous trees, dug small holes (50 cm×40 cm×30 cm), applied 250 g of 45% chlorine based compound fertilizer to each hole, and mashed the seedlings. In the second year, all miscellaneous irrigation would be completely removed, and block shaped hole expansion would be carried out. In the second year, 250 g of 45% chlorine based compound fertilizer would be applied to each plant. In the third year, mixed irrigation would be completely eliminated.
