Abstract: Silicon fertilizer application was studied with bamboo (Phyllostachys pubescens) stands of mid-low yield on the rhyolite weathing crust soil which has lower available silicon content in Anji county, Zhejiang Province. Randomized complete block design (RCBD) was used in the field plan. The results of statistical analysis for 12 experimental plots are as follows: Applying silicon fertilizer to increase bamboo yields was ineffective despite of lower soil available silicon content (4.62 mg/100g soil). Diagnosis and recommendation integrated system (DRIS) was used for evaluating nutrient status of Si for bamboo function leaves, it indicated that Si nutrient level was suitable in the midst of stands, even if bamboo stands may obtain higher yield for N, P and K fertilizer system. On the basis of realitical status of widespread bamboo natural range in China, applying silicon fertilizer is not necessary.
