Effects of Different Culture Measures on the Soil Nutrient,Microorganism and Enzymatic Activity in Oiltea Camellia Stands

The soil nutrient,microorganism and enzyme activity were studied and analyzed in Oiltea camelli plantations in Changning area.The results showed the differences of microorganism quantity among different types of soil was significant,so were the enzyme activity and soil nutrient.However,distribution of the nutrients and enzymatic activities in the soil profile was same.With the depth added,the soil nutrient,microbe populations and enzyme activities declined continually.The soil nutrient,microorganism and enzyme activity in the farming land were obviously higher than those in other types of soil.Moreover,it was revealed that the soil nutrient was closely related to the change of biological properties and among themselves.The correlation among soil microorganism quantity,enzyme activity and soil nutrient content is significant,it can be used as evaluation index of soil fertility.
