Coated type organic slow-release compound fertilizer

Abstract

The invention discloses coated type organic slow-release compound fertilizer which is prepared from the following components: 1% to 3% of poultry manure, 1% to 5% of humic acid, 0.1% to 0.5% of nitrogen-fixing bacteria, 0.2% to 1.5% of pesticide, 1% to 4% of water-soluble organic silicon, 15% to 35% of isobutylidene-diurea coated urea, 2% to 8% of isobutylidene-diurea coated ammonium dihydrogen phosphate, 1% to 5% of nitrogen-pyridine, 0.1% to 0.5% of ferrous sulfate and the balance of smashed straw, wherein the poultry manure can provide organic matter and microelements for the fertilizer; the humic acid can achieve fertilizer synergia, improve soil, stimulate crop growth and improve the quality of agricultural products; the nitrogen-fixing bacteria have a nitrogen fixing effect; as the compound fertilizer contains a lot of organic matter and can attract more pests, the certain pesticide assistance is needed to avoid plague of insects; the organic silicon can absorb the fertilizer to form certain-degree slow release; urea is coated by isobutylidene-diurea to achieve a slow-release effect; ammonium dihydrogen phosphate is coated by the isobutylidene-diurea to achieve a slow-release effect; the nitrogen-fixing pyridine can achieve a nitrogen fixing effect; as the poultry manure is added, the ferric sulfate serves as a deodorant to be added; the smashed straw serves as base fertilizer of the coated type organic slow-release compound fertilizer.

Description

Technical field [0001] The invention relates to a fertilizer, in particular to a coated organic slow-release compound fertilizer and its production process. Background technique [0002] The current fertilizers in my country are mainly a mixture of macro-elements, medium-trace elements and additives. The content of trace elements is low, and non-slow-release fertilizers have poor fertilizer efficiency, narrow application range, and limited crop types. In recent years, with the increasing application of compound fertilizers in production, the production ratio of compound fertilizers is unreasonable, and the phenomenon of unreasonable use of compound fertilizers has become increasingly prominent. The production cost of compound fertilizers is high and the fertilization effect is not ideal. Especially the sustained-release effect is not ideal. Summary of the invention [0003] The purpose of the present invention is to provide a coated organic slow-release compound fertilizer, which...

Problems solved by technology

[0002] The current fertilizers in my country are mainly a mixture of macroelements, medium and microelements and additives. The content of trace elements is low, and it is not a slow-release fertilizer.

In recent years, with the continuous increase in the application of compound fertilizers in production, the production ratio of compound fertilizers is unreasonable, and the phenomenon of unreasonable use of compound fertilizers has become increasingly prominent, resulting in high production costs of compound fertilizers and unsatisfactory fertilization effects. Especially the sustained release effect is not ideal
