Medium trace element capsule fertilizer and preparation method thereof

Abstract

The invention belongs to the field of crop fertilizers, and belongs to a medium trace element capsule fertilizer suitable for being used in modern agriculture and a preparation method thereof. The medium trace element capsule fertilizer is prepared from superphosphate, medical stone powder, ammonium sulfate, agricultural zinc sulfate, agricultural ferrous sulfate, agricultural borax, soluble starch, trace elements, hydrophilic polymer materials, citric acid powder, amino acid, surfactants, azedarach, quisqualis seeds, gallnut, pubescent holly roots, soapberry testa, Chinese honeylocust fruit, isatis roots, rhizoma atractylodis and cellulase. The problem of yield reduction due to plant diseases and insect pests and nutrition substance absorption insufficiency can be effectively solved; the fertilizer utilization rate can be improved; the regulation on salt-affected soil can be improved.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and more precisely relates to a medium and trace element capsule fertilizer suitable for modern agriculture and a preparation method thereof. Background technique [0002] The existing formula of compound fertilizer products is unreasonable, and the single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, and the utilization rate is low, and some even cause low-quality agricultural products, endangering the health of consumers; the physical properties are not good, and there is much dust , not compressive, caking, inconvenient for storage, transportation and fertilization. Phosphorus and potassium in commonly used compound fertilizers are easily fixed by calcium, magnesium, iron, aluminum and other metal ions in wastewater, which reduces the utilization rate of fertilizers. Excessive addition not only increases the cost of chemicals, but also easily exceeds the standard of ...

Problems solved by technology

[0002] The existing formula of compound fertilizer products is unreasonable. The single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, and the utilization rate is low. Some even cause low-quality agricultural products and endanger the health of consumers; the physical properties are not good, and there is much dust. , not compressive, caking, inconvenient for storage, transportation and fertilization

Phosphorus and potassium in commonly used compound fertilizers are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum in wastewater, which reduces the utilization rate of fertilizers. Excessive addition not only increases the cost of chemicals, but also easily exceeds the standard of phosphorus content in the effluent
