日照茶树种植区典型茶园的土壤肥力状况评价

Assessment of Soil Fertility in Typical Tea planting Areas in Rizhao City

摘要:

通过野外采样和室内测定，以日照茶树种植区3个典型茶园为研究对象，每个茶园分别取鸠坑、黄山群体、福鼎大白各3个品种，最终取得9种茶样生长地的土样，研究分析土样的pH，有机质，全N，P，K，有效N，P，K等指标的土壤养分含量状况，并以此为评价指标，运用模糊综合评判法，对3个茶园的土壤肥力质量进行了综合评价。结果表明，茶园肥力综合水平为北垛春>碧波山庄>北叶青；茶园土壤总体上，pH值较适中，有机质含量很缺乏，全N含量偏低，全P含量中等，全K含量较高，有效N含量很缺乏，有效P含量非常丰富，有效K含量中等，并据此提出了关于该地区3个典型茶园今后合理施肥的一些建议。

Abstract:

Through collecting samples in the field and determination in the door, regarding 3 typical tea[CD*2]planting areas as the studying objects, choosing 3 kinds of tea in each tea planting aera respectively, soil samples in 9 tea planing areas have been gained. soil fertilitity contents of pH, organic matter, total N, P and K, available N, P and K have been studied. Regarding these results as evaluation ratio, by using fuzzy comprehensive assessment method, soil fertility quality of 3 typical tea planting areas in Rizhao city have been comprehensively evaluated. As showed by the result, the tea plantation integrative fertility level is Beduochun>Biboshanzhuang>Beyeqing. In general, pH value of tea planting areas are relatively moderate, organic matter is scarce, total N content is low, total P content is medium, total K content is higher, effective N content is very lack, effective P content is extremely rich, and effective K content medium. According to the results, some suggestions for the construction of typical tea gardens in this area are put forward.
