Abstract
The invention provides a fertilizer composition for bamboo. The fertilizer composition comprises 10 to 90 weight percent of slow release fertilizer and the balance of compound fertilizer at least containing nitrogen, phosphorus and potassium; in the fertilizer composition for the bamboo, the mass ratio of N to P2O5 to K2O is 1:(0.25-0.7):(0.2-0.6). In the invention, slow release fertilizers are mixed with common fertilizers, and nutrients in the common fertilizers are quickly blended in the soil and absorbed by bamboo plants for improving the growth of the bamboo plants; and the slow release fertilizers release the fertilizers according to the requirements of the bamboo plants so as to maintain longer manurial effect, which improves the utilization ratio of the fertilizers and can reduce fertilization times and labor intensity. The fertilizer composition for the bamboo of the invention can effectively promote the growth of the bamboo plants and improve the soil. Experiments show that after the fertilizer composition for the bamboo of the invention is applied to a bambusa textilis forest, the nutrient content of the soil and bamboo leaves of annual new adult bamboos are high.
