Effect of Shrubby Training on Ecological Benefit of Populus cathayana Plantation
HU Bingbin
Abstract：In order to increase ecological benefit of Populus cathayana plantation,we investigated the effects of shrubby training and single trunk training on forest growth,forest microenvironment,plant community under forest,health degree of trees,and protection costs in tianzhu county of Gansu province.The result showed that the shrubby training increased forest growth,improved forest microenvironment,increased the vegetation growth under forest,increased the health degree of trees,and decreased protection costs.The crown density,crown diameter,dry weight of single plant on the ground,air humidity in the forest,soil relative water content,vegetation cover under forest,number of species,density,height and above-ground dry weight were increased 105.00％,87.36％,32.20％,15.81％,29.14％,37.89％,33.33％,80.00％,29.16％,and 46.64％than single trunk training,respectively.The tree height,air temperature in the forest,strength of illumination,damage rate by long horned beetle,top dry rate,wind folded rate,mortality rate,protection costs and weight of domestic garbage were decreased 51.48％,18.21％,43.79％,100.00％,100.00％,100.00％,100.00％,38.78％,and 54.44％than single trunk training,respectively.The difference of different test index between shrubby training and single trunk training was extremely significant level separately.
