摘　　要：采用野外调查采样和室内分析相结合的方法,对银川市西夏区贺兰山东麓葡萄4个相对集中种植区的64个土壤样品进行养分含量测定和统计分析,探讨研究区土壤养分含量的差异,并采用单项指数和改进的内梅罗综合指数法对土壤肥力现状进行评价,以期为葡萄合理施肥,优质丰产提供科学依据和基础数据。结果表明:西夏区贺兰山东麓葡萄种植区土壤pH为7.68~8.59,土壤偏碱性;土壤有机质、土壤碱解氮、速效磷的平均含量分别为12.73g·kg-1、10.35mg·kg-1、63.09mg·kg-1;有机质含量偏低,碱解氮含量极度贫乏,而速效磷含量处于极高水平;综合评价结果表明,西夏区贺兰山东麓葡萄种植区土壤综合肥力属于贫瘠水平,碱解氮含量低是土壤肥力的主要限制因子,土壤综合肥力状况表现为银川市园林场>芦花台园林场>镇北堡>张裕酒庄葡萄园;适当增加有机肥、氮肥的施用量并平衡施肥,是提高西夏区贺兰山东麓葡萄种植区葡萄品质的重要环节。Soil nutrient status of the wine-growing region in the eastern foot of the Helan Mountains in Xixia district were studied,in order to provide scientific basis for the fertilization,and realize superior quality and high yield.By using field investigation and indoor analysis,determination and statistic analysis of soil nutrient content of the 64 soil samples from the main wine-growing region had been completed.To figure out their differences of soil nutrient content.The soil fertility was evaluated by single item and Nemoro comprehensive index method.The results showed that soil pH of the wine-growing region in the eastern foot of the Helan Mountains in Xixia district was 7.68-8.59.The contents of soil organic matter,soil alkalystic N,available P were 12.73g·kg-1,10.35mg·kg-1,63.09mg·kg-1.Soil pH was mostly alkaline.Organic matter content was low.Alkalystic N was very low.But available P was very high.Evaluation results showed that the soil integral fertility was poor level in the wine-growing region in the eastern foot of the Helan Mountains in Xixia district.Low alkalystic N was a major limiting factor in soil fertility.The soil synthetical fertility showed that,Yinchuan Forest FarmLuhuatai Forest Farm〉Zhenbeibu〉Changyu vineyard.Appropriate increase of organic fertilizer,proper amount of nitrogen fertilizer and balanced fertilization was an important link to improve the quality of grape.
