摘要
以重庆市永川区典型茶叶生产基地的茶园土壤为研究对象,选用pH值、有机质、全N、有效P、交换性K、交换性Mg、有效Mn、有效Cu、有效B和有效Zn含量共10个土壤肥力指标作为评价参数,应用Fuzzy综合评判法对肥力进行数值化综合评价。结果表明:永川茶园土壤整体肥力质量为中等,其中属于中上水平的占54.5%,属于中下水平的占45.5%;茶园土壤酸化严重,有机质处于中等水平,全N基本上超过了0.1%,有效P低于15.0 mg/kg,交换性K都未达到指标(80 mg/kg),有效Cu、有效Zn含量丰富,交换性Mg、有效Mn、有效B缺乏。生产中就加强肥培管理,以促进肥力的可持续性。
The ten tea garden soil indexes of pH,organic matter,total Nitrogen,available Phosphor,exchangeable Kalium,exchangeable Magnesium,available Manganese,available Cuprum,available Boron and available Zinc from the city of western tea Chongqing Yongchuan district were determined.Ten indexes by Fuzzy synthesize estimation were evaluated.Results showed that the soil fertility of Yongchuan district was in midrange.54.5 % was better,and 45.5 % was worse.The soil acidification was serious,organic matter was intermediate level,total Nitrogen was over 0.1 %,available Phosphor was under 15.0 mg/kg and exchangeable Kalium was below standard（80 mg/kg） in every tea production base.There were rich in available Cuprum and available Zinc,and were short of exchangeable Magnesium,available Manganese and available Boron.
