Problems solved by technology

At present, water-soluble fertilizer products are mainly powder products and liquid products. Most of the powder products have low active ingredient content, slow dissolution, low plant utilization, poor stability during long-term storage, and are prone to agglomeration or moisture absorption. There are many insoluble substances, which are easy to block the nozzles and equipment pipelines, and cannot adapt to modern agriculture.
On the other hand, only a small part of the fertilizer applied to the soil over the years is absorbed and utilized by the crops of the current season, and the remaining 70-80% of the fertilizer is fixed by the soil, forming phosphate and nitrate precipitation residues, destroying the aggregate structure of the soil, causing Decreased soil fertility and poor arability

Abstract

A multi-nutrient major-element water-soluble fertilizer powder product is provided. The product includes urea, urea phosphate, ammonium polyphosphate, potassium nitrate, potassium dihydrogen phosphate, calcium nitrate, magnesium sulfate, water-soluble trace elements, wormcast, a composite chelating agent, a growth regulator, Solifix and a carboxymethyl cellulose-grafted N-isopropylacrylamide copolymer. The water-soluble trace elements include two or more of iron, copper, zinc, boron, manganese and molybdenum compounds. The composite chelating agent is a composition of disodium ethylenediamintetraacetate and biodegradable ethylenediamine-N,N'-disuccinic acid. The growth regulator is one of diethylaminoethyl hexanoate, alpha-naphthaleneacetic acid or indoleacetic acid or a composition thereof in any ratio. A preparing method of the product is simple and the product is cheap. The product has a high fertilizer efficiency, balanced nutrients, good water solubility, capability of being environment-friendly and pollution-free, and scientific and reasonable component proportions, and can be stored for long time without caking.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a multi-nutrient macroelement water-soluble fertilizer powder product with scientific and reasonable nutrient composition ratio, high solubility and fast dissolution speed, and no caking during long-term storage and a preparation method thereof. Background technique [0002] Most of the macro, middle and micro elements required for crop growth and development need to be supplemented by fertilization, except for a small part supplied by soil, air and water. However, the single type of conventional fertilizer products, low concentration, and poor water solubility cause an extreme imbalance of nutrients in the soil and crops, which seriously leads to a decline in crop yield and quality. Due to the poor quality of farmers in our country, in order to achieve the goal of balanced fertilization, the types and proportions of nutrients needed by crops cannot be g...
