摘　　要：以贺兰山东麓6个酿酒葡萄子产区典型葡萄园为研究对象,分析0~60 cm土层土壤pH和有机质、氮、磷、钾、全盐含量特征,采用修正的Hedley磷分级方法测定磷素形态。结果表明,试验所选贺兰山东麓酿酒葡萄园土壤pH均值为8.33,呈碱性,有机质和全氮、全磷含量平均为7.18、0.36、0.44 g·kg^(-1),处于全国较低水平;碱解氮、有效磷和速效钾平均为23.21、11.23、63.05 mg·kg^(-1),分别处于6、3、4级水平。6个子产区之间土壤肥力存在一定差异,其中以银川产区土壤综合肥力最高,且养分具有表聚性。Hedley磷分级中无机磷是磷素的主要供给源,其中盐酸提取态磷和残余态磷含量最高。相关性分析表明,碳酸氢钠-无机磷(0.79*)和树脂磷(0.43)是有效磷的主要来源。以上结果可为后期施肥及磷素管控提供参考依据。Taking six typical vineyards at the eastern foot of Helan Mountains as research object,the characteristics of soil pH and the content of organic matter,nitrogen,phosphorus,potassium,and total salt in the 0-60 cm soil layer were analyzed.The phosphorus forms were determined using the modified Hedley phosphorus classification method.The results showed that average pH value of the soil was 8.33,showing alkalinity.The average content of organic matter,total nitrogen,and total phosphorus were 7.18,0.36,0.44 g·kg^(-1),which were at a relatively low level in the country;the average levels of alkaline hydrolyzed nitrogen,available phosphorus,and available potassium were 23.21,11.23,63.05 mg·kg^(-1),respectively,at levels of 6,3,4.There were certain differences in soil fertility among the six producing areas,among which the Yinchuan area had the highest comprehensive soil fertility and nutrients had surface aggregation.In Hedley's phosphorus classification,inorganic phosphorus was the main source of phosphorus supply,with the highest content of HCl-Pi and Residual-P.Correlation analysis showed that sodium bicarbonate inorganic phosphorus(0.79*)and Resin-P(0.43)were the main sources of available phosphorus.The above results could provide reference basis for later fertilization guidance and phosphorus control.
