| 摘 要： | 采集重庆市金果园9个园区的土壤样品，调查和评价果园土壤的肥力状况。结果表明果园各园区土壤均呈强酸性，pH在4.55以下，且pH随土层深度的增加而降低。结合全国第2次土壤普查的养分分级标准，各园区表土中有机质、全氮、碱解氮和速效磷的含量基本处于中等或中上水平；全磷、全钾和速效钾含量偏低，处于较缺和缺乏状态；不同深度果园土壤样品中养分含量存在明显差异，表现为表层含量显著高于下层。分析果园常施的2种有机肥（鸡粪和油饼）的肥力状况，发现油饼中有机质含量较丰富，但2种有机肥的氮、磷、钾含量配比难以满足高需钾果树的需求。 |

| Abstract: | Fertility status in orchard soil was investigated and assessed by collection and analysis of the soil samples in 9 gardens ofGolden Orchard,Chongqing.It was found that all of the orchard soil showed strong acidity with pH lower than 4.55,and pH decreased with the depth of soil layer increasing.Based on the classification standard of soil nutrients in the second soil investigation of China,the contents of soil organic matter,total nitrogen,available nitrogen,and available phosphorus in the surface layer soil... |
