Balanced-nutrient instant water-soluble fertilizer powder and preparation method thereof

Abstract

The invention discloses balanced-nutrient instant water-soluble fertilizer powder which is prepared from the following raw materials in parts by weight: 100-150 parts of straw, 20-30 parts of water-soluble trace elements, 2-3 parts of a chelating agent, 40-60 parts of earthworm excrement, 10-20 parts of bamboo charcoal, 6-9 parts of composite bacterial floras and proper amounts of lignin peroxidase and cellulase. According to the powder, the straw is subjected to enzymolysis through ultrasonic waves, so that the enzymolysis time can be greatly shortened while the enzymolysis rate is increased;due to freezing drying and vacuum drying, active substances and nutrient components beneficial to crops in the raw materials can be maintained to the maximum extent; due to superfine crushing, the fertilizer powder is small in particle size, high in dissolution degree, high in dissolution speed, in addition easy to absorb by the crops, small in amount of finished product fertilizers, high in croputilization rate and high in stability; and equipment such as a nozzle is not blocked, the soil fertility can be improved while the stress resistance of the crops can be improved, micro-ecological environments of soil can be improved in long-term use of the fertilizer powder, the number of microorganisms in the soil can be increased, and the pollution situations of conventional soil can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to nutritionally balanced instant water-soluble fertilizer powder and a preparation method thereof. Background technique [0002] Most of the macroelements, secondary elements and microelements required for the growth of crops are obtained through soil, air and water, and most of them need to be obtained through fertilization. However, the conventional fertilizer products currently on the market are single in type, low in concentration, and poor in water solubility, resulting in an extreme imbalance of nutrient elements in the soil and crops, resulting in a decline in crop yield and quality; and only a small amount of fertilizer has been applied to the soil over the years Absorbed and utilized by the crops of the season, most of the fertilizer is fixed by the soil, forming phosphate and nitrate precipitation residues, destroying the aggregate structure of t...

AI Technical Summary

Problems solved by technology

At present, water-soluble fertilizers are mainly divided into powder products and liquid products. Most of the powder products have the characteristics of slow dissolution, low content of active ingredients, low plant utilization rate, poor stability, easy to agglomerate or decompose by moisture absorption, many insolubles, and easy to block the nozzle. and equipment pipelines, unable to meet the requirements of modern agriculture
