不同退耕还林模式土壤物理性质研究
Preliminary Studies on Soil Physical Characteristics in Different Patterns of Converting Farmland to Forest
对洪雅县13种不同退耕还林还模式下的土壤容重、毛管孔隙度、非毛管孔隙度、毛管持水量、总孔隙度等六项物理性指标进行比较、分析。试验结果表明：（1）通过比较0～20cm和20～40cm土层得出，三倍体毛白杨+麻柳模式的土壤容重值均较高，麻竹+三倍体毛白杨的值最低。（2）麻竹+三倍体毛白杨的毛管孔隙度、毛管持水量和土壤总孔隙度三项物理性指标值最高，三倍体毛白杨+麻柳模式的这三项值最低。总的来说，麻竹+三倍体毛白杨混交模式对土壤有明显的改良作用。
Soil physical characteristics of thirteen different patterns of converting farmland to forest in Hong’ya County were studied, such as soil bulk density, capillary porosity, no-capillary porosity, capillary water and soil porosity. The results showed that (1) after comparing with the 0～20cm and 20～40cm layers, the soil bulk density of Dendrocalmus latiflorus +Pterocarya stenoptera pattern was the highest, and Dendrocalmus latiflorus + Triploid Populus tomentosa pattern was the lowest; (2) the capillary porosity,soil bulk density and capillary water of Dendrocalmus latiflorus + Triploid Populus tomentosa pattern were the highest among the thirteen different patterns, and Dendrocalmus latiflorus +Pterocarya stenoptera pattern was the lowest. In conclusion, Dendrocalmus latiflorus + Triploid Populus tomentosa pattern was a proper model for improving soil quality
