Abstract:

Bamboo compound fertilizer is a special fertilizer for Phyllostachys heterocycla cv.Pubescens growth,which is formulated based on the biological characters of Phyllostachys heterocycla cv.Pubescens and balance fertilizing.In this paper,the fertilizer of N,P and K were selected and used in experiment and practice,according to mixed design method.Based on the experimental data,mathematical models of projects and economic benefit were established,and an optimum combining scheme for practice was formed by computer simulating and optimizing.After application,the economic benefit of Phyllostachys heterocycla cv.Pubescens forest would increase about 35%.

Key words: Phyllostachys heterocycla cv.Pubescens, Simplex check, Compound fertilizer, Simulating
