| 摘 要： | 采用常规方法对山东省烟台市周边地区不同种植年限果园土壤理化性质和微生物数量进行了调查.结果表明:在不同土层中,随着种植年限的增加,果园土壤pH值和含水量的变化没有明显的规律性;果园土壤有机质和全磷含量呈增加的趋势,而全氮和全钾含量呈降低的趋势.不同种植年限果园土壤的三大类微生物的相对数量并没有很大的变化,仍然是细菌最多,放线菌次之,真菌最少;在不同土层中,随着种植年限的增加,土壤细菌和真菌数量呈增加的趋势,土壤放线菌数量呈降低的趋势.

| Abstract: | In this paper,the influence of planting age of garden on soil physicochemical property and microbe quantity in Yantai area was studied by normal methods.The results showed that with the increase of planting age,the change of pH and soil moisture had no obvious rule;the quantity of organic matter and total P increased,while the content of total N,K decreased in different soil layer.The relative number of microorganisms was not changed in garden soil,and the number of bacteria,actinomycetes and fungi reduced in turn.With the increase of planting years,the number of bacteria and fungi enhanced,and the number of actinomycetes decreased in different soil layer. |
