Special compound fertilizer for eucalyptus prepared from tree branch ash and inorganic fertilizers

Abstract

The invention belongs to the field of research into novel fertilizers. The special compound fertilizer for eucalyptus is prepared by combining ash, which is generated after a biomass generating station generates power by utilizing tree branches, with inorganic fertilizers according to the growth features and fertilizer demand characteristics of eucalyptus. The total nutrients of the compound fertilizer account for 35.32-45.18%, wherein nitrogen accounts for 14.30-15.89%, phosphoric anhydride accounts for 14.00-16.22%, and potassium oxide accounts for 7.02-15.14%. The prepared special fertilizer for eucalyptus comprises the following fertilizers in parts by weight: 24-26 parts of urea, 29-35 parts of monoammonium phosphate, 8-24 parts of potassium chloride, 8-24 parts of tree branch ash, 3-6 parts of acidity regulator and 7-9 parts of adhesive. The invention belongs to a special fertilizer for eucalyptus, and can satisfy the fertilizer demands for eucalyptus growth; and the manufacturing technique of the special compound fertilizer for eucalyptus is simple, and lowers the processing cost for tree branch ash.

Description

technical field [0001] The invention belongs to the field of novel fertilizer research, and in particular relates to a special compound fertilizer for eucalyptus, which uses ash content of tree branches and inorganic fertilizers as raw materials. Background technique [0002] China is a large forestry country. The total biomass of forest trees in the country is about 19 billion tons, the available amount is 900 million tons, and the total amount that can be used as energy is about 300 million tons. The use of biomass as a renewable resource for power generation can be regarded as a solution to energy An important channel of crisis. However, 3%-20% residues will be produced after biomass power generation combustion. With the rapid development of biomass power plants, the resource utilization of the residues generated by power plants is particularly important. The ashes of trees and branches after biomass power generation are rich in nutrients such as phosphorus and potassium...

Problems solved by technology

But the shortcoming of this kind invention is that the nutrient content of compound fertilizer is low, and only has two kinds of macronutrients of phosphorus and potassium

Patent No. 2006100669649.4, a Chinese invention patent application titled "A Method for Producing NPK Compound Fertilizer Using Straw Ash" discloses a method for producing NPK compound fertilizer using straw ash, although the compound fertilizer contains nitrogen, phosphorus and potassium, but its total nutrient content is lower than the minimum nutrient content requirement of inorganic compound fertilizer stipulated by the state at present, and the compound fertilizer does not meet the characteristics of eucalyptus growth.
