| 摘 要： | 集约经营下雷竹林土壤性质的改变可能影响雷竹的持续高产。通过比较研究集约经营的雷竹与稻田土壤中铝形态及变化,以了解导致雷竹林衰败的可能土壤因素,为雷竹林的可持续经营提供依据。结果表明,雷竹种植后,土壤酸化严重,养分累积明显,活性铝含量急剧增加。土壤酸化及相应的铝毒极可能是导致雷竹林衰败的主要土壤因素。

| Abstract: | The degradation of soil quality may result in a low production of the bamboo(Phyllostachy spraecox cv.Prevernalis) under intensive management.In this paper,aluminum and its transformation in the bamboo and rice paddy soils were investigated to determine the soil factors inducing the bamboo withering.The results showed that soil acidification was severe and soil nutrients accumulation was significant,but the amount of active aluminum increased dramatically.Soil acidification and induced Al toxicity may be the main factor resulting in the failure of the sustainable bamboo production. |
