苹果种植区的土壤养分含量情况研究—以白水县为例

为了稳定和提高苹果产量，通过对2013 年渭南白水县500 个点农业土壤区进行分析，并对土壤pH、全氮、有机质、碱解氮、速效钾、有效磷、有效铁和有效锰、锌、铜进行有效的对比研究。利用Microsoft Excel 2010 软件进行数据整理统计。结果发现：白水县苹果生长的土壤酸碱度为中性偏碱，并且土壤中的全氮和有机质的含量丰富，速效钾较丰富；有效锌、有效磷含量适中；有效铜含量高，有效铁、碱解氮、有效锰含量低。

Soil Nutrient Content of Apple Planting Area in Baishui

The paper aims to stabilize and improve apple yield. The authors analyzed 500 agricultural soil zones in Baishui, Weinan, Shaanxi in 2013, and made a comparative study on pH value, total nitrogen, organic matter, alkali- hydrolyzable nitrogen, rapidly available potassium, available phosphorus, available iron, available manganese, available copper and available zinc. On the basis of the statistical data from Microsoft Excel 2010, the paper drew a conclusion that: the soil zones of Baishui where apple trees were planted had neutral to alkali pH, abundant total nitrogen and organic matter, rich rapidly available potassium, normal available phosphorus and zinc, profuse available copper, and a little available iron, alkali- hydrolyzable nitrogen and available manganese.
