Alga-based organic slow-release compound fertilizer

Abstract

The invention relates to an alga-based organic slow-release compound fertilizer which comprises the following components: 1-3% of alga, 1-3% of tobacco dust, 2-5% of plant ash, 1-5% of fulvic acid, 0.1-0.5% of azotobacter, 15-35% of isobutydine-diurea-coated urea, 2-8% of isobutydine-diurea-coated ammonium dihydrogen phosphate, 1-5% of nitrogen-pyridine, 0.1-0.5% of triacontanol, 0.1-0.5% of 2-diethyl aminoethyl hexanoate, 0.1-0.5% of sodium indolebutyrate and the balance of pulverized straw. The alga is used as an organic matter fertilizer and corrosion inhibitor; the plant fibers and lignin in the tobacco dust are utilized to provide organic fertilizers; the plant ash provides a potash fertilizer and minor elements for the compound fertilizer; the fulvic acid enhances the effects of the fertilizer, improves the soil, stimulates the plant growth and improves the agricultural product quality; the azotobacter performs the nitrogen fixing function; the urea is coated in the isobutydine diurea to have the slow-release effect; the ammonium dihydrogen phosphate is coated in the isobutydine diurea to have the slow-release effect; the nitrogen-pyridine performs the function of nitrogen fixation; and the combination of the triacontanol, 2-diethyl aminoethyl hexanoate and sodium indolebutyrate is used as a growth regulator. The alga-based organic slow-release compound fertilizer belongs to a base fertilizer.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a seaweed-based organic slow-release compound fertilizer and a production process thereof. Background technique [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. The fertilizer efficiency is poor, the scope of application is narrow, and the types of crops suitable for it are also limited. 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. Contents of the invention [0003] The obje...
