Potassium-rich microcapsule fertilizer and preparation method thereof

Abstract

The invention discloses a potassium-rich microcapsule fertilizer and a preparation method thereof. The organic-potassium-rich fertilizer is composed of the following components in parts by weight: 14-18 parts of potassium sulfate, 0.7-1.8 parts of ferrous sulfate, 6-9 parts of ammonium sulfate, 13-15 parts of diammonium phosphate, 0.7-1.8 parts of borax, 5-8 parts of bentonite, 4-7 parts of kieselguhr, 5-8 parts of high-calcium clay, 3-6 parts of zeolite, 4-6 parts of fulvic acid, 20-25 parts of plant straw, 4-7 parts of microelement and the like. Due to the adoption of potassium-rich plants, including feather cockscomb, Phytolacca acinosa, coneflower, stylosanthes guianensis and Grain Amaranth, the organic components of the fertilizer are increased, and the organic potassium content of the fertilizer is enhanced.

Description

technical field [0001] The invention relates to a microcapsule fertilizer rich in organic potassium and a preparation method thereof. Background technique [0002] At present, due to the increasing use of chemical fertilizers, most of the varieties used are unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and weakened water and fertilizer retention. The blind 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, there is a lot of dust, they are not compressive, agglomerated, and it is not easy to store , transportation and fertilization. Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or ...

Problems solved by technology

[0002] At present, due to the increasing use of chemical fertilizers, most of the varieties used are unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and weakened water and fertilizer retention. The blind 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, there is a lot of dust, they are not compressive, agglomerated, and it is not easy to store , transportation and fertilization

Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum, and are easily adsorbed by clay mineral particles, thereby reducing fertilizer efficiency and affecting environmental pollution

Excessive addition not only increases the cost of chemicals, but also the content of inorganic potassium in the effluent is likely to exceed the standard
