本文根据15个土壤剖面分析测定和59个竹鞭样方调查资料,研究安徽省舒城县龙河地区水竹择伐异龄林土壤的物理性质和化学成分与地下鞭生物量、竹鞭分布深度、壮鞭比例间的关系。土壤中含砂量为62—72%,含粉粒量为22、64%,含粘粒量为11—18%,水竹地下部分生物量高,土壤有机质含量与水竹地下部分总生物量呈线性相关:(?)=31287.9557x-4567.6394,有效磷含量在13—33ppm 时,地下部分总生物量较高,有效氮、磷含量与地下部分总生物量无显著相关,地下部分总生物量与有效氮、磷、钾含量的关系:(?)=33518.01—22.47x_1+148.22x_2+759.48x_3,壮龄鞭比例与有机质和有效氮含量间线性相关显著,与磷、钾含量无显著相关性,土壤质地疏松、孔隙适中,肥沃的土壤中,竹鞭分布较深。
Based on the analysis of 15 soil profiles and the survey data of 59 whip whip-like plots, this paper studied the distribution of physical and chemical components, Depth, the relationship between the magnificent whip ratio. Soil sand content of 62-72%, the amount of particles containing 22,64%, with clay content of 11-18%, water bamboo underground biomass, soil organic matter content and water bamboo underground part of the total biomass (?) = 31287.9557x-4567.6394, the effective total phosphorus content of 13-33ppm, the underground part of the total biomass is higher, the available nitrogen and phosphorus content and the underground part of the total biomass was not significantly related to the underground part of the total biomass (?) = 33518.01-22.47x_1 + 148.22x_2 + 759.48x_3, the correlation between the ratio of organic matter and available nitrogen was significant, and there was no significant correlation between phosphorus content and potassium content , Loose soil texture, moderate porosity, fertile soil, bamboo whip deep distribution.
