不同气候条件下紫色土的微生物数量比较

The Contrast of Microbe Quantity in Purple Soil under Different Climate Condition

通过对云南省的元谋地区和四川省的内江、仁寿两种气候条件下紫色土理化特性和微生物数量的分析 ,探讨热带干热河谷和亚热带润湿气候区不同气候条件对紫色土微生物数量和土壤理化特性的影响。分析试验说明 ,处于不同气候条件下的紫色土微生物的数量不同 ,活性不同 ,使紫色土的生物和化学风化过程有异 ,导致不同地区紫色土的理化特性不同。润湿气候地区由于适宜的水热状况 ,紫色的细菌和真菌数量多高于干热气候地区 ,而放线菌的数量则是干热气候地区高于润湿气候地区。

By analysing Chemical-physical characteristics and miorbe quantity of purple soil under the different climate condition,which were situated in Yuanmou county of Yunnan povince and Neijiang city of Sichuan province,the influence of physical-chemical nature and microbe quantity by tropic arid-hot valley region ahd subtropic humic region were studied.The analytical experiment explained that under the different climate condition,the microbe quantity and microbe activity were different which made the biological-...
