不同抚育措施对新植油茶林生长量的影响

Influence of Different Thinning Measures on the Growth of New Forest Planting of Camellia oleifera

试验通过对当年新植油茶林采用不同抚育措施的生长量进行比较,结果表明:不同抚育措施对当年新植油茶林的生长量的促进效果存在显著差异。以环山水平带状垦复(预留生草带)+扩穴培土、施肥技术措施(A)的生长量最大,苗木保存率最高;全面垦复(不留生草带)+扩穴培土、施肥措施(B)的生长量和苗木保存率次之;只进行扩穴培土抚育措施(C)的生长量和苗木保存率最低。同时,试验结果还表明:环山水平带状垦复+施肥+预留生草带的抚育措施(A)病虫害发生率最低。

Growth of the new plant of Camellia oleifera forest on that year by different tending measures was compared in this test,results showed that： the promoting results of different tending measures on growth of newly planted forests of Camellia oleifera on that year was significantly.Reclaim the mountains horizontal belt（reserving grass band） ＋ extended cave and keeping soil,technical measures of fertilization（A） have the largest growth and the highest rate of seedlings stored;the growth and preservation rate of seedlings of comprehensive reclamation（not-reserving grass band） ＋ extending cave and keeping soil,fertilization measures（B） followed by;only the expanding cave and keeping soil（C） has the lowest growth and seedlings save rate.Meanwhile,test results also showed that： the tending measures of mountains horizontal belt reclaim ＋ fertilizer ＋ reserve grass band（A） have the lowest incidence of pests and diseases.
