摘要:通过对赣南硬头黄竹生长情况和土壤理化性质进行调查和测定,分析硬头黄竹生长状况、立地条件及其相关性。结果表明:随着土层深度的增加,土壤容重呈现增大的趋势,水分状况和孔隙状况指标呈现减小的趋势。不同养分指标随着土层深度的增加,变化趋势不同,总体表现为表层土壤养分含量高于下层土壤。同全国第二次土壤普查养分分级标准相比,除了碱解氮处于丰富状态外,其余养分含量处于中等~极缺乏状态;土壤中Mg和S元素含量严重缺乏;Zn元素含量略低于亏缺临界值,其余营养元素含量较丰富。硬头黄竹生长指标与土壤物理性质和化学性质存在一定的相关性,胸径和新叶SPAD值与土壤物理性质间的相关性较高,枝下高分别与容重和总孔隙度呈显著负相关和显著正相关,与其他物理性质间相关性不显著;其余指标与土壤物理性质间相关性均不显著。生长指标中有机质和全氮分别与出笋数和退笋数、有效磷与胸径、枝下高和新叶SPAD、全钾与胸径和新叶SPAD、速效钾与胸径、枝下高和单丛立竹数均呈显著或极显著相关关系。因此,为了硬头黄竹林高效经营,应该根据硬头黄竹生长状况及需肥特性,合理施入P、K肥以及微量元素肥料,补充林地营养、维持地力,促进硬头黄竹的生长。
The object of the study was to reveal the characteristic of soil physico-chemical properties and its correlation with the growth of Bambusa rigida in Gannan, Jiangxi Province, China. B. rigida is a good material for building and paper making, as a landscaping bamboo specie, it also has good ornamental value. In this paper, the growth ofB. rigida adopted method of fixed sample survey, and the sampling soil was determined by laboratory method, to provide a theoretical basic for the nutrient and bamboo forest management. The results showed that with the soil depth increased, bulk density increased, while moisture and porosity of soil decreased. Change trend of different nutrient indexes of soil was different. Compared with the national standard of the second soil census, only the content of Alkali-hydro N kept high level, other nutrient contents kept deficient or mid-high level. The content of Mg and S was severely deficient; the content of Zn was slightly lower than Deficient critical value, while others nutrient elements were abundant. The growth ofB. rigida and soil physical properties existed a certain correlation. The correlation of soil physical properties with DBH and SPAD new leaves was higer. Organic matter and total nitrogen, respectively, and growth indicators showed significant or highly significant correlation. Therefore, in order to promoting the growth and efficiently manage B. rigida forest, rational fertilization and maintaining soil fertility based on growth and fertilizer demand is necessary.
