Soil Fertility Properties and Spatial Distributio of Phyllostachys praecox cv.prevernalis Stand

Determinations were implement in 2014 on soil fertilities, such as pH, organic carbon, alkali-hydrolysale nitrogen, available phosphorusand available potassium at 0-30 layer in Phyllostachys praecox cv. prevernalis stands in Lin’an and Yuhang, Zhejiang province. Analysis were madeon spatial variation character. The result demonstrated that contentw of organic carbon, alkali-hydrolysale nitrogen, available phosphorus andavailable potassium were higher, but pH was lower. Spatial distribution of pH was lower in the north part and higher in the south, that of availablephosphorus and potassium higher in the north and lower in the south, and that of organic carbon, alkali-hydrolysale nitrogen higher in the southwestand lower in the northeast. Investigations showed that management measures of the stands had great effect on spatial distribution of organic carbon,alkali-hydrolysale nitrogen, while spatial distribution of pH, available phosphorus and potassium was influenced by soil types and managementmeasures.
