| 摘 要： | 对文安县不同林龄的中林-46(Zhonglin-46)杨人工林的土壤微生物和酶活性进行了测定分析。结果表明不同林龄的土壤微生物和土壤酶活性均存在差异,0～20cm的表土层明显高于20～40cm的亚表层和40～60cm深层。在测定时间内(2006年4-11月)各个林龄的土壤微生物总数在春季较高,夏季较低,秋季又增高,总体上表现为高-低-高的变化。土壤微生物和酶活性之间表现出较高的相关性,土壤微生物的总数和酶活性随着取样深度的增加均表现为逐渐降低。

| Abstract: | The study has undertaken to investigate the soil microbe populations and enzyme avtivities at different soil layers in poplar Zhonglin-46 plantation communities of Wenan county.The soil microbe populations and enzyme activites at 0~20cm depth were higher than that of 20~40cm and 40~60cm.During the experiment time,from Apr to Nov in 2006 ,the total of the microbe populations and enzyme activities had shown a trend of high-low-high .There is a good correlation between the microbial populations and enzyme activities. With the depth added,the microbe populations and enzyme activities declined continually. |
