| 摘 要： | 在砂岩黄壤上生长了25年的茶园连续5年研究了硫酸钾对茶园土壤钾库及钾素平衡的影响。结果表明,施用钾肥能明显提高土壤钾库中的速效钾和缓效钾含量,但对土壤全钾含量影响不大;连续4年不施钾肥的土壤速效钾、缓效钾、全钾含量均呈下降趋势。

| Abstract: | A typical and representative yellow sand soil grown teas for 25 years in Chongqing was collected for five years successive field experiments in order to study potassium forms and equilibriums in tea-grown soils.The results showed the average contents of available K,slowly released K in potassium pools in tea-grown soils were significantly increased by potassium fertilizer.And the total K were affected less by potassium fertilizer.The average contents of available K,slowly released K and total K reduced continuously without fertilization treatments. |
