Abstract: In order to obtain the suitable formula fertilization of Dendrocalamus farinosus,the formula fertilization was conducted for Dendrocalamus farinosus with the fertilizers of nitrogen, phosphorus, potassium and silicon by the way of L₉(3⁴)orthogonal design in calcareous purple soil in Muchuan County of Leshan City, Sichuan Province. The results showed that the fertilizer order of effect on bamboo shoots and new bamboos was:silicon > potassium, nitrogen > phosphorus. For the number and rate of bamboo shoot deterioration, the order turned to be as:ilicon > potassium > phosphorus > nitrogen. And for bamboo shoots and new bamboos, there were very significant differences among different disposals of nitrogen, phosphorus, potassium and silicon, but the number of bamboo shoot deterioration was not significantly different.It was recommended that annual fertilization rate was 650 g urea, 400 g calcium superphosphate,120g potassium chloride and 600g silicon fertilizer for each clump of bamboos in calcareous purple soil.
