Soil Fertility Evaluation of Phyllostachys praecox cv. prevernalis Stand in Yuhang and Countermeasures

292 sample plots were established in July and August of 2013 in Phyllostachys praecox cv. prevernalis stands with mulching and fertilization in Yuhang, Zhejiang province for determination of soil fertilities. The result demonstrated that mean soil organic matter reached 32.06 g/kg, mean alkali-hydrolyzale nitrogen, available phosphorous and available potassium had respectively 167.12, 111.61, 206.99 mg/kg. The result also showed that 51.4%, 62.5% and 40.7% of tested soil had first grade content of alkali-hydrolyzale nitrogen, available phosphorous and available potassium. Mean soil pH was 5.0, 34.7% of tested soil was less than 4.6. Soil pH had negative relationship with determined soil fertility index, especially significant (P<0.01) with of alkali-hydrolysable nitrogen and available phosphorous. Moreover, there were significant positive correlations (P<0.01) with either two of the four fertility index. Directive fertilization and lime application was recommended for balance of fertility, decrease of soil acidification and diffused pollution.
