摘  要：
试验对贵州省遵义地区3种不同干扰程度下,金佛山方竹[Chimonobabusa utilis(Keng)Keng f.]成竹矿质元素的含量进行了研究。结果表明,金佛山方竹的干、枝、叶中矿质元素的含量是不同的,Mg、Ca、Fe、K、P、N 6种元素在叶中的含量最多(均值分别为4.444 0、13.266 3、0.795 8、0.667 0、1.967 1、15.568 4g/kg),其次是枝(1.606 5、0.675 9、0.367 8、0.609 7、1.482 8、6.100 4 g/kg),再次是干(0.709 7、0.470 3、0.126 8、0.376 2、0.668 9、2.248 1 g/kg);不同程度的干扰对干中的Ca含量影响显著,其中重度干扰>中度干扰>轻度干扰;对枝中K、P、N 3种元素的含量影响显著,分别是轻度干扰>中度干扰>重度干扰、轻度干扰>重度干扰>中度干扰、轻度干扰>中度干扰>重度干扰;对叶中Mg、K、P、N 4种元素的影响显著,分别是重度干扰>轻度干扰>中度干扰、轻度干扰>中度干扰>重度干扰、重度干扰>轻度干扰>中度干扰、重度干扰>轻度干扰>中度干扰;从干、枝、叶的总含量看,轻度干扰下Fe、K、N 3种元素的含量较高,重度干扰下Mg、Ca、P的含量较高,而中度干扰对矿质元素含量的影响不大。

摘  要：
The mineral element content in Chimonobabusa utilis(Keng) Keng f.with three different extent interference was studied in Zunyi,Guizhou province.The results indicated that,first,contents of mineral elements were different in stems,branches and leaves of C.utilis;Second,the Mg,Ca,Fe,K,P,N mineral elements were most abundant in leaves(4.444 0, 13.266 3,0.795 8,0.667 0,1.967 1,15.568 4 g/kg),more in branches(1.606 5,0.675 9,0.367 8,0.609 7,1.482 8,6.100 4 g/kg),less in stems(0.709 7,0.470 3,0.126 8,0.376 2,0.668 9,2.248 1 g/kg);Third,different degrees of interference had significantly impact on the content of mineral elements in the bamboo.The content of Ca in stems was influenced by serious interference> moderate interference> mildly interference.K in branches: Mildly interference> moderate interference> serious interference.P in branches: Mildly interference> serious interference> moderate interference.N in branches: Mildly interference > moderate interference> serious interference.Mg in leaves: Serious interference> mildly interference> moderate interference.K in leaves: Mildly interference> moderate interference> serious interference.P in leaves: Serious interference> mildly interference> moderate interference.N in leaves: Serious interference > mildly interference> moderate interference.Last the level of Fe,K,N were higher under mildly interference,the level of Mg,Ca,P were higher under serious interference,but the effect of moderate interference on mineral element content was very small.
