Fertilization experiment of high-yielding bitter bamboo forest

A fertilization experiment of high-yielding bitter bamboo forest was carried out. The results showed that fertilizer application could increase the bamboo shoot output, the timber production and the exiting bamboo wood production, but different fertilizing treatments had various effects on the growth and yield of bitter bamboo forest; and nitrogen had the biggest influence on the yield of bitter bamboo, phosphorus had the secondary and potassium had the less effect. In addition, in farming practice, the potassium fertilization could be deleted or with small dosage in the red soil developed from granite-porphyry.
