| 摘 要： | 2010～2011年，研究了6种不同种植年限胡椒园的土壤养分、酶活性及土壤微生物类群。结果表明：随着种植年限的增加，胡椒园土壤有机质、有效氮、有效钾含量呈下降趋势，而有效磷呈逐年累积的趋势。土壤酶中磷酸酶和脲酶活性，在种植15 a时出现峰值，而后随种植年限增加而减小，过氧化氢酶和蔗糖酶活性无明显变化规律，磷酸酶与种植年限相关性显著。种植9、15 a样地的土壤微生物总量大于CK，其余年份逐渐减少，其中细菌、放线菌数量与总量的变化趋势基本一致，而真菌的数量随年限增加而增加。因此，胡椒种植15 a后应该注意培肥土壤，或者通过轮作等措施防止连作障碍的现象发生。

| Abstract: | Six soil samples with different culture years of black pepper were collected in 2010 and 2011. The soil nutrient content, rhizosphere microorganisms and activities of soil enzymes were analyzed to obtain the microbial ecological characteristics in black pepper field of different continuous cropping periods. The results indicated that some of the several indicators of the microbial ecological characteristics were changed regularly with the increasing of the continuous cropping periods. Others showed no significant changes. The correlation and effect of these changes needs further research. |
