摘要
不同坡位因其工地条件不同 ,毛竹林的立竹株数和平均胸径均有不同程度的差异 ,说明土壤理化性质 (如土壤松紧度、土壤肥力 )等对毛竹林的质量好坏具有决定性的作用 ;深翻和施肥均能提高毛竹林的质量 ,立竹度和毛竹胸径增量最大的是深翻并施全元肥 45 0 kg/hm2的处理 ,但与深翻并施全元肥 3 0 0 kg/hm2 ,处理之间的差异不大 .因此 ,毛竹低产林最佳的综合改造措施是劈草留阔、全面深翻、补植并施全元肥 3 0 0 kg/hm2。
In a typical bamboo grove, the number of culms established and the mean diameter at breast high vary with the slope position. This is indicative of the essential role the physical as well as the chemical properties of the soil play in determining the grove quality. It is found that the bamboo grove can be upgraded by deep digging and fertilizer application. Different treatments have shown that the maximum growth in terms of the stocking density and diameter increment can be achieved when a dosage of 300~ 450 kg/ha of compound fertilizer is applied.
