Controlled-release water-soluble fertilizer containing humic acid and preparation method of fertilizer

The invention relates to a controlled-release water-soluble fertilizer containing humic acid. The fertilizer comprises the raw materials by weight percent: 5-10% of humic acid, 15-20% of zinc sulfate, 20-25% of borax, 45-60% of magnesium sulfate, 0.2-2% of poly-aspartic acid, 0.5-2% of ethylenediamine tetraacetic acid disodium and 0.1-0.5% of caproic acid diethylamino alcohol ester. In the fertilizer, potassium humate is taken as a raw material, a little amount of poly-aspartic acid and ethylenediamine tetraacetic acid disodium are added into the raw material, so that three elements including Zn, B and Mg are complexed after being dissolved or in the dissolving process, and slowly released to the soil, and then absorbed by crops, thus the fertilizer nutrient is prevented from running off, and the absorption utilization rate of the nutrient substance can be improved; the product is convenient to use, and can be used as seed fertilizer or base fertilizer; the product can be instantly and completely dissolved, and is applied by flushing or spraying and drop irrigation; the controlled-release water-soluble fertilizer containing humic acid is the first choice for realizing efficient water-saving agriculture and integrating water and fertilizer. The controlled-release water-soluble fertilizer containing humic acid is especially suitable for supplementing trace elements such as Zn, B and Mg for commercial crops such as vegetables, seed production corns, oil crops, fruit trees and grapes which have high requirement for the fertilizer application level.
