摘  要:
通过研究切根和中耕措施对沙区樟子松人工林生长与健康的影响得出:切根和中耕措施能明显减轻樟子松近熟林的感病情况,控制成熟林病情的发展,同时也能促进近熟林胸径生长,但对成熟林胸径生长影响并不明显;樟子松细根主要分布区在地下0~80 cm,切根和中耕措施能促进近熟林细根量的增加。

摘  要:
In this study,the influences of cutting roots and intertillage on growth and health of Pinus sylvestris var.mongolica plantations were investigated.The results indicated that cutting roots and intertillage declined the disease significance in near-mature forest of Pinus sylvestris var.mongolica and controlled the disease development in mature forest.Besides,cutting roots and intertillage increased the diameter of trees in near-mature forest but shown insignificant influence to trees in mature forest.The 0~80 cm soil layer was the main distribution area of fine roots,and cutting roots and intertillage increased the number of fine roots.
