摘 要:
为探索连续垦植对山区茶园土壤性状的影响,促进茶产业经济与水土保持的协调发展,分析了连续垦植模式下贵州鸟王茶产地茶园土壤主要化学性质及碳、氮、磷含量。结果表明:连续垦植模式下土壤有机碳、全磷、全氮含量最大值都出现在2010年,最小值都出现在2008年,变化规律表现为2010年>2011年>2009年>2008年。不同年份土壤p H值变化为2008年﹥2011年﹥2009年﹥2010年。长期栽培茶树的土壤,有进一步酸化的趋势,不同年份土壤中营养元素含量不同,主要是长期使用化肥所致。土壤C/N比随年份增长逐渐变小;同年份土壤C/P比差异较大,土壤N/P比变化与土壤C/P比有相似规律。

摘 要:
To explore the effects of continuous cultivation on soil characteristics in mountainous tea gardens and promote the coordinate development of tea industrial economy and water and soil conservation,the main chemical properties and contents of C,N and P of tea garden soil in Guizhou Niaowang tea producing area under continuous cultivation were analyzed. Results: The maximum and minimum values of contents of organic carbon,total P and total N under continuous cultivation appeared in 2010 and 2008 respectively,showing the sequence of 2010 >2011 > 2009 > 2008. p H was 2008 > 2011 > 2009 > 2010. Soil acidification aggravated after cultivating tea trees for years,long-term use of chemical fertilization caused the variation of soil nutrients in different years. Soil C / N decreased gradually with time prolonging; Soil C / P varied greatly in the same year,which was similar to soil N / P.
