对西双版纳割胶、未割胶条件下橡胶林土壤酸性磷酸酶活性动态变化特征及其对不同保护带种植方式(距瓣豆绿肥覆盖与野生杂草覆盖)的响应研究。结果表明,7～12月份橡胶林土壤酸性磷酸酶活性呈现先下降后升高的变化趋势,土壤酸性磷酸酶活性具有表层(0～20 cm)>中层(20～40 cm)和底层(40～60 cm)垂直差异。不同管理方式下橡胶林土壤酸性磷酸酶活性表现为:割胶处理>未割胶处理,距瓣豆绿肥覆盖土壤>野生杂草覆盖土壤。橡胶林土壤酸性磷酸酶活性与全氮、全磷呈显著或极显著正相关。
Dynamic Change of Soil Acid Phosphatase Activity and Its Response to Planting in Different Types of Protective Belts (Covering with Green Manure from Fava Bean and Cover with Wild Weeds) in. The results showed that soil acid phosphatase activity decreased first and then increased in July and December, and soil acid phosphatase activity had the highest level of soil acid phosphatase (0 ~ 20 cm)> middle layer (20 ~ 40 cm) and lower layer (40 ~ 60 cm) vertical difference. Soil acid phosphatase activity of rubber plantation under different management modes was as follows: tapping treatment> no tapping treatment, soil covering from the loamy green manure> wild weeds covering the soil. Soil acid phosphatase activity in rubber plantation had significant or very significant positive correlation with total nitrogen and total phosphorus.
