短穗兔耳草克隆生长与土壤养分的相关性分析

本研究选择未退化、轻度退化、中度退化、重度退化和极重度退化草地上的短穗兔耳草(Lagotis brachystachya)为研究对象,对短穗兔耳草克隆生长与土壤养分的相关性进行了研究,研究结果显示:PH值对短穗兔耳草匍匐茎数量的影响较为明显,而土壤的全氮、全磷、全钾对短穗兔耳草匍匐茎数量的影响不明显;土壤中全氮、全磷含量的高低对短穗兔耳草基株重的影响较为明显,而土壤的全钾含量和PH值对短穗兔耳草基株重量的影响不明显;土壤中全氮、全磷、全钾含量及PH值的高低对短穗兔耳草分株重的影响均不明显。

THE CORRELATION ANALYSIS OF SOIL NUTRIENTS AND CLONAL GROWTH OF LAGOTIS BRACHYSTACHYA

This study choose not degradation, mild degradation, moderate degradation, severe degraded and the extremely severe degraded meadow Lagotis brachystachya as the research object, and the correlation of clonal growth of Lagotis brachystachya and soil nutrient was studied. The results showed that PH and Lagotis brachys- tachya stolon number is relatively obvious, the influence of otal phosphorus, total potassium and stolon number of Lagotis brachystachya effect is not obvious ; total phosphorus content and genet weight was evident, and the influence of total potassium content and PH value and genet weight of Lagotis brachystachya effect is not obvi- ous; total phosphorus, total potassium content, PH value and stolon - ramet weight of Lagotis brachystachya effects are not obvious.
