- 摘要:
- 采用分层分段挖掘法对黄土丘陵区梨枣人工林细根生物量、根长密度和比根长的空间分布特征，以及这些根系指标与土壤养分的关系进行了研究。结果表明：梨枣细根根量与根长密度，均随水平距离和土层深度的增加而减小；比根长，在垂直方向上0～40 cm范围内随土层深度的增加而减小，在水平方向上0～90 cm随水平距离的增加而增加。土壤养分含量（除全P外）平均值在土层深度0～20 cm和水平距离0～30 cm土层含量高于其它各土层。相关性结果表明，吸收根根量、根长密度与土壤中的有效性养分存在显著相关性（R2=0.6472、0.6869），特别是土壤中速效K、速效N的含量对于根系的生长有明显的促进作用。比根长与土壤养分含量相关关系不明显。
- Abstract:
- The space distribution characters on the biomass，root length density and specific root length of fine root of Ziziphus jujube cv.Lizao plantation，and the relationship between soil nutrients by layered and sectional mining method in Hilly Loess Regions were studied.The results showed that both fine roots root biomass and root length density of ?Ziziphus jujube cv.Lizao decreased with an increase of horizontal distance and soil depth.Specific root length decreased in the vertical direction within the range of 0~40 cm soil depth increase，while increased with the horizontal distance increase within the range of 0~90 cm in horizontal direction.The average content (in addition to all P outside) of soil nutrient was higher than the other in 0~20 cm soil depth and in 0~30 cm soil layer horizontal distance.Correlation results showed that there had a significant correlation (R2=0.6472,0.6869) among the absorption stud，root length density and soil nutrients in the effectiveness，especially the content of effective K,available N promoted roots’ growth significantly.The correlation of specific root length and soil nutrient content was not obvious.
