【摘要】 试验表明:在一定密度的野生方竹林,方竹出笋数量与母竹立竹量无关,劈山、垦复、施肥等经营措施间与出笋有极显著差异,劈山与垦复之间差异不显著,施肥对出笋有极显著差异,多元素复合肥与尿素间存在极显著差异,但复合肥与磷酸二氢氨之间差异不显著;垦复、施肥等经营措施对方竹自然成竹率有明显提高作用,经营措施间存在极显著差异;母竹平均胸径大小与新成竹平均胸径大小成正比,垦复、施肥后平均胸径增幅明显,但各经营措施间对胸径增长量还未达到差异显著程度。更多还原

【Abstract】 Experiment on effect of management on growth of wild Chimonobambusa quadrangularis demonstrated that shooting amount had no relation with mother bamboo, but had significant relation with cleaning, reclamation and fertili- zation. Reclamation and fertilization had effect on increasing survival rate of bamboo. Mean D.B.H of mother bamboo had positive relation with the young ones. Reclamation and fertilization could increase mean D.B.H. but it was not evident among different management.更多还原
