摘要:
通过采样与分析，研究了上黄试区不同土地利用类型、不同坡地植被恢复措施及不同植被恢复年限的土壤养分状况，结果表明坡耕地土壤存在不同程度的退化现象，土壤养分，有机质含量较低；坡耕地与不同恢复措施的林地草地相比，速效K、速效N及有机质含量低，pH值则偏高；坡耕地退耕还林还草年限越长土壤改良效益越明显。
Abstract:
Based on sampling and analyses, the effects on soil nutrients of different types of land use, different vegetative measures in sloping cultivated land and different years of vegetative restoration were studied. The results show that:there are, to some degree, degenerated phenomenon in the soil of cultivated land, the contents of nutrient and soil organic matter are relatively low; comparing with the different methods of restoration, the contents of available N, K and soil organic matter are relatively low, while the pH is relatively high. The longer the converting farm land to forest and grass land the more effect of soil betterment.
