Effects of Different Site Preparation Ways on Soil Physical and Chemical Properties of Pinus koraiensis Forestland

Li Wei;Department of Forest Diseases and Pests,Xiuyan Forestry Bureau,Anshan City,Liaoning Province;  
The effect of different soil preparation methods on soil physical and chemical properties of Pinus koraiensis forest was studied by three kinds of siol preparation methods(overall soil preparation,strip soil preparation and spot soil preparation).Result shows that the three soil preparation methods can significantly improve soil physical properties,improve soil gas permeability,accelerate microbial activity,and play a role in improving soil fertility after the soil preparation within a short time.After three years of soil preparation overall soil preparation and strip soil preparation appear trend defore returning to the soil preparation;the ferlility was improved slightly by adopting spot soil preparation.It illustrates that the two modes(overall soil preparation and strip soil preparation)can significantly improve soil physical properties in a short period of time,but it is not conducive to the long-term maintenance of soil fertility,and the soil erosion under the spot soil preparation method is less,which helps maintain soil fertility.
