武当道茶土壤养分现状分析及对策

Current Status of Soil Nutrition and Countermeasures of Wudang Taoism Tea

对武当道茶55个典型茶园土壤进行取样和分析测定,结果表明,武当道茶茶园土壤pH总体较高;土壤有机质、碱解氮含量丰富;有效磷含量中等水平,分布随海拔升高而降低;土壤速效钾亏缺面积较大,分布随海拔升高而升高。在此基础上提出了其改良培肥途径,即增施有机肥、提高土壤有机质含量、推广测土配方施肥技术、调节土壤酸碱度等。

The status of soil nutrition of 55 representative Wudang Taoism Tea gardens was analyzed and some improvement countermeasures were put forward in this study.The experiment results indicated that pH value and the content of organic matter and available N of soil in Wudang taoism tea gardens were high.The content of available P was middle and decreased with the uprising of altitude.The content of available K was low and the area of K-deficient soil was large.The content of available K increased with the altitude uprising.Based on these,some improvement approaches were put forward as follows,increasing the application of organic manure,extending the formula fertilization technique and adjusting soil pH value.
