新平县茶园土壤养分特征及肥力质量评价
Nutrient Characteristics and Assessment for the Fertility Quality of the Tea Plantation Soils in Xinping County
摘要
Abstract
[Purposes]The soil fertility status of tea plantation in Xinping County was studied to provide a reference for the high-efficiency nutrient management of tea plantations in Xinping County.[Methods] Through field investigation and indoor analysis, fuzzy comprehensive evaluation method was applied. Based on 9 soil fertility quality indexes, we evaluated comprehensively the quality of soil fertility of 8 main tea plantations in Xinping County. [Results]The soil pH of tea plantation was between 4.4-5.83 and the soil pH had reached the requirement of high quality tea plantation in Xinping County. The average content of organic matter (OM), total nitrogen (TN), total phosphorus (TP), total potassium (TK), effective nitrogen (AN), effective phosphorus (AP) and effective potassium (AK) were 57.1 g/kg, 0.269%, 0.077%, 1.51%, 206.3 mg/kg, 11.0 mg/kg and 154 mg/kg, respectively. The nutrient index of the tea plantation soil had reached Ⅰ -level standard except for average content of cation exchange capacity (CEC). The soil fertility index (IFI) of tea plantation was0.769 and for higher levels, in turn, was Zhelong (0.877)>Gasa (0.851)>Mosha (0.807)>Pingzhang (0.799)>Shuitang (0.796)>Jianxing (0.734)>Pingdian (0.647)>Xinhua (0.642), higher level 75%, upper level accounted for 25%. The contents of TP, TN, OM, CEC, AK and AP in soil had great influences for fertility quality.[Conclusions]The soil fertility of the tea plantation in Xinping County is generally higher, but the content of AP is relatively low, and the phosphate fertilizer should be emphasized to promote.关键词
