摘　　要：为快速建成高质量木荷防火林带,本研究以木荷人工林带为研究对象,调查统计了不同造林抚育方式下木荷林成活率、保存率、树高和胸径等数据,分析不同造林抚育方式对木荷林生长的影响,核算不同造林抚育方式的资金投入并进行比较,为木荷防火林带建设提供参考。结果表明,栽植当年,处理Ⅰ和处理Ⅱ苗木成活率更高,影响有统计学意义(P<0.01);栽植3年,处理Ⅰ和处理Ⅱ的木荷苗木保存率更高,影响有统计学意义(P<0.01);栽植7年,处理Ⅰ和处理Ⅱ的木荷苗木胸径和树高均更高,影响有统计学意义(P<0.05);3种造林抚育处理方式苗木费相同,处理Ⅰ的人工费和肥料费投入相对较高。结合不同造林抚育方式对木荷林生长的影响,选择处理Ⅱ营造木荷防火林带较为适宜,即全面劈除杂灌并块状铲草,不残留针叶树;挖小穴(50 cm×40 cm×30 cm),每穴施45%氯基复合肥250 g,苗木打浆;第2年全面劈除杂灌,块状扩穴,每株施45%氯基复合肥250 g;第3年全面劈除杂灌。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
