Soil improvement coated fertilizer containing animal bone powder and preparation method thereof

Abstract

The invention discloses a soil improvement coated fertilizer containing an animal bone powder, and is characterized in that the soil improvement coated fertilizer is prepared from the following raw materials in parts by weight: 19-22 parts of a beet sugar residue, 23-26 parts of a corn sugar residue, 33-37 parts of a sugarcane sugar residue, 1-2 parts of borax, 3-4 parts of magnesium sulfate, 1-2 parts of ammonium molybdate, 1-2 parts of cobalt chloride, 3-5 parts of copper sulfate, 9-11 parts of a molecular sieve powder, 8-10 parts of diatomite, 15-20 parts of the animal bone powder, 56-60 parts of a tea seed cake, 67-70 parts of a tung seed cake, 4-6 parts of an EM agent, 8-10 parts of a soil improvement agent, and a proper amount of water. Various sugar residues, the tea seed cake and other organic matters are fermented and then combined with the animal bone powder and the inorganic fertilizers, and a coating process is added, so that the prepared fertilizer has a slow release effect, is balanced and lasting in fertility, and also solves the problem of environmental pollution caused by improper handling of animal residual bodies; and the fertilizer effectively improves soil, reduces the pH value of the soil, and retains water and fertilizers.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a soil-improving coated fertilizer containing animal bone powder and a preparation method thereof. Background technique [0002] Plants need a lot of nutrients to promote their rapid growth during the growth process. Different soils have certain effects on the growth of crops, which requires effective soil improvement. Existing fertilizers for soil improvement can only see the impact of fertilizers on crops, but cannot effectively improve the soil. Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest; especially the saline-alkali land occupies a considerable land area in my country and the world. It is too heavy to be cultivated, and some have invested a lot of money to improve, to discharge alkali and suppress salt, but with little effect. ...

The existing soil-improving fertilizers can only see the impact of fertilizers on crops, and cannot effectively improve the soil

Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest; especially saline-alkali land occupies a considerable land area in our country and even countries in the world. It is too heavy to be cultivated, and some have invested a lot of money to improve, to discharge alkali and suppress salt, but with little effect
