Humic acid type fertilizer brick specially used for garden seedling trees, and application method of fertilizer brick

Abstract

The invention provides a complete-nutrition humic acid type fertilizer brick specially used for garden seedling trees, and an application method of the fertilizer brick in order to solve the problem of easiness in hardening of soil fertilized with seedling tree fertilizers in the prior art. The fertilizer brick is produced from, by weight, 35-45 parts of activated humic acid, 17-23 parts of biogas residues, 8-12 parts of charcoal, 8-10 parts of potassium chloride or potassium sulfate, 13-17 parts of urea, 10-15 parts of bentonite and 5-7 parts of monoammonium phosphate. The fertilization object is 5 or above years old seedling trees. The fertilizer brick is produced through selecting novel fertilizer production raw materials comprising humic acid, biogas residues and charcoal, adopting soil test formula fertilizing technology raw materials, adding inorganic nutrients and adopting a controlled release fertilizer technology through a novel technology, so the fertilizing problem of the garden seedling trees is solved, organic nutrients and inorganic nutrients are provided, and the soil can be rapidly improved in a short period by the humic acid, biogas residues and active carbon.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer brick suitable for garden seedlings. Background technique [0002] Humic acid is the remains of animals and plants, mainly the remains of plants, which is a type of organic substance caused and accumulated by a series of processes of microorganisms, decomposition and transformation, and geochemistry. The most promising humic acid resources to be developed and utilized are coals with low calorific value, such as peat, lignite and weathered coal. However, humic acid raw powder cannot be directly applied to agriculture, and can only be applied after activation. [0003] "Turning waste into treasure" of organic waste is an urgent problem to be solved in our country. Organic waste such as straw, livestock and poultry manure, and grain-based dregs are discharged at will to pollute the environment. Although it contains a large amount of organic matter, it cannot be directly applied to agr...
