Problems solved by technology

However, fulvic acid itself is easy to absorb moisture. When it is added to water-soluble fertilizers, it is prone to problems such as uneven mixing and serious moisture absorption. Especially when the storage environment is not good, it is more likely to have a large amount of agglomeration, which seriously affects the fertilizer. use
This also seriously restricts the application and development of water-soluble fertilizers containing fulvic acid.

Abstract

The invention discloses a water-soluble fertilizer containing fulvic acid and a preparation method of the water-soluble fertilizer, which belong to the technical field of fertilizers. The water-soluble fertilizer is prepared from urea, monoammonium phosphate, potassium nitrate, ammonium molybdate, amino acid powder, an anti-caking agent, a chelating agent, manganese sulfate, boric acid, ferrous sulfate, magnesium sulfate and fulvic acid according to a certain weight ratio. Since the anti-caking agent as a specific component is added in the water-soluble fertilizer, a layer of film can be formed on the surface of the fertilizer to effectively wrap the surface of the fertilizer, consequently, the production of fertilizer salt bridges and the diffusion of a saturated solution are blocked, andwhile fertilizer caking is effectively prevented, the instant solubility of the fertilizer is not influenced. The nutrition of the water-soluble fertilizer disclosed by the invention is balanced andcomplete, no antagonistic effect exists between nutrients, the balanced supplementation of a variety of nutrient elements to crops is realized, and the fertilizer can be rapidly dissolved, promotes the balanced absorption to the nutrients by plants, and particularly has a remarkable effect in increasing the yield of rape and influencing quality.

Description

technical field [0001] The invention relates to a water-soluble fertilizer, in particular to a water-soluble fertilizer containing fulvic acid and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and chemical fertilizers are the material guarantee for the sustainable development of agriculture and the basis for increasing grain production. The practice of the world's agricultural development has proved that the application of chemical fertilizers is the fastest, most effective and most important measure to increase production. However, the irrational use of chemical fertilizers over the years has not only caused a large amount of waste of economy and resources, but more seriously has caused a series of problems such as serious acidification and alkalinization of a large number of fertile fields, soil compaction, and environmental pollution. Water-soluble fertilizer is a multi-element compound fertilizer that can be comp...
