Special compound fertilizer for bamboo and preparing method thereof

Abstract

A special compound fertilizer for bamboo takes urea, ammonium phosphate, potassium chloride, organic materials and bentonite as the main raw materials, and the raw materials are processed into granular fertilizer, the weight percentages of the components are as follows: 15 percent of organic matter, 10 percent to 12 percent of N, 4 percent to 5 percent of P2O5, 10 percent to 12 percent of K2O, the proportion of N to P2O5 to K2O is 2 to 3:1:2 to 3, and the total nutrient accounts for 25 percent to 28 percent; the organic materials are one or mixture of more than two materials of vinasse, peat, bamboo waste and treated papermaking sludge, or that the organic materials are fermented and matured, thus forming the organic fertilizer. By using the special compound fertilizer for bamboo, the bamboo product can increase 15 percent to 20 percent, namely, the product per mu can increase over 210kg. The fertilizer can provide necessary nutrient elements timely in different stages according to the growth characteristics of bamboo, and the fertilizer has the advantages of high safety, high efficiency, less investment, according with the developing direction of fertilizer industry, meeting the demand of rapid growth and steady product of bamboo and being especially suitable for application to paper pulp sympodial bamboo stands.

Description

technical field [0001] The present invention relates to inorganic fertilizers, and also to organic fertilizers, in particular to compound-mixed fertilizers, and specifically to special fertilizers for bamboo crops. Background technique [0002] Bamboo belongs to Gramineae and is an important forest plant in tropical and subtropical regions of my country. According to statistics, the existing bamboo forest area in my country is about 7.2 million hm 2 , of which the artificially managed bamboo forest area is 4.2 million hm 2 . Due to its special growth advantages and important economic value, it has been paid more and more attention by countries all over the world. In order to increase the yield, chemical fertilizers are widely used in planting bamboo at present. However, long-term application of a single nitrogen fertilizer will reduce the organic matter content of bamboo forest soil year by year, destroy the aggregate structure, and soil fertility decline; at the same ti...
