经过对 7年生不同造林方式的幼林生长状况分析可知 ,5种造林方式幼林生长差异显著 ,“炼山 +人工铲草”造林方式效果最好 ,使用除草剂会抑制苗木生长 ,不炼山同样因杂草繁茂抑制苗木生长 ,7年生时最佳处理C比最差处理E的胸径、树高、蓄积、保存率分别高 37.9%、30 .0 %、30 1.5%、82 .5%。不同造成林方式对杂灌木生长影响不一样。造林当年除草保苗管理至关重要 After 7 years of different afforestation methods of young forest growth analysis shows that five afforestation methods significantly different growth of young forests, “Lian + Artificial shoveling” afforestation the best way, the use of herbicides will inhibit the growth of nursery stock, not the same mountain The lush weed suppressed the growth of seedlings, and the optimal treatment C at 7 years old was 37.9%, 30.0%, 30 1.5% and 82.5% higher than the worst treatment E respectively. Different types of forest caused by the impact on the growth of shrubs are not the same. Reforestation seedling management is crucial
