Evaluation of Soil Fertility Quality of Tea Gardens in Eastern Fujian

Tea Research Institute, Fujian Academy of Agricultural Sciences, Fu'an, Fujian 355015, China

摘要: 以闽东地区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、交换性Ca、有效Cu、有效B和有效Zn含量共10个土壤养分肥力指标作为评价参数,应用Fuzzy综合评判法对茶园土壤肥力质量进行数值化综合评价。结果表明:闽东地区茶园土壤整体肥力质量属于中上水平的占60%,属于中下水平的则占40%。通过Fuzzy综合评判法推算出的土壤肥力综合指标值IFI与春茶产量显著相关,较好地反映出闽东地区的土壤肥力状况。

Abstract: Ten tea gardens in eastern Fujian were tested for their soil pH, organic matter, total nitrogen, available phosphor, exchangeable kalium, exchangeable magnesium, exchangeable calcium, available manganese, available cuprum, available boron and available zinc for the quality determination. These indices were subjected to the fuzzy comprehensive evaluation. The IFI value significantly correlated with the yield of the spring tea. Hence, the soil fertility could be well defined by using these indices. The fertility of the tea gardens in the eastern Fujian regions was above average, that is, 60% of them were higher and 40% lower than the national average.
