| 中文摘要: |
| 2009-2011年在闽侯县采集果园土壤样品441个，对9个土壤养分指标进行检测分析。分析结果表明：土壤有机质含量处于丰富水平，3年来处于丰富水平的样本数占样本总数的比例分别为64.6%、60.0%和51.0%。；碱解氮含量处于中等偏低的水平，处于缺乏水平的样本数占总样本数的比例分别为31.5%、37.5%和50.0%；有效磷含量处于丰富水平；速效钾含量处于中等偏低水平。80%以上的果园土壤pH值呈酸性和微酸性。土壤有效锌含量处于丰富水平，交换性钙和交换性镁含量均有一定程度的缺乏，而有效硼含量缺乏尤其严重。 |

| 9 soil nutrient indexes were tested and analyzed on 441 soil samples collected from orchards in Minhou County from year 2009 to 2011. The results showed that the organic matters were abundant currently while they were decreased year by year on the overall basis. The content of available nitrogen was between the level of suitable and slightly low, within which the percentage of soil samples with deficient available nitrogen increased on the yearly basis. In terms of the content of available phosphorus, the overall level was abundant. In addition, the overall content of available potassium was at the level of suitable and slightly low. The soil pH values were mainly acid and weak-acid. The contents of available Zn were abundant, which the general deficiency of exchangeable Ca and exchangeable Mg were detected and the severe deficiency of available B was also detected. |
