| 摘 要： | 以吉林省梨树县农田防护林为对象,进行经营技术研究,结果表明:及时进行幼林抚育,可使造林成活率和保存率分别提高11.8个百分点和14.8个百分点;树高和胸径生长量分别提高20%和24%。修枝强度不同效果差异显著,以1/3修枝强度效果最佳,可降低风速26.2%,防护距离为树高的26倍。间伐强度控制在25%～30%时效果最好,间伐后林木分布均匀,树高和胸径生长有所提高,林带内卫生状况有较大的改善。

| Abstract: | The management technology of farmland shelterbelt was studied in Lishu county of Jilin province.If the juvenile forest tending was conducted in time,the survival and maintenance increased 11.8% and 14.8%,and the height and diameter at breast height increased 20% and 24%.The effect of pruning on shelterbelt was significant.The 1/3 pruning intensity was the best treatment for farmland shelterbelt,which could reduce 26.2% wind speed and the protection distance was 26 times of tree height.The 25%~30% thinning intensity was the best choice,as the height and DBH growth both increased and it was neat within the shelterbelt. |
