Problems solved by technology

For inorganic fertilizers, it mainly provides elements such as carbon, phosphorus, and potassium. Its advantages are high nutrient content, fast fertilizer effect, strong fertilizer, and can play a role in quick effect and product improvement; its disadvantage is that it generally does not contain organic matter, only It can supply crop nutrients, improve soil and cultivate soil fertility. The effect is short, the effective time is short, the fertilizer effect is not long-lasting, it is easy to volatilize, lose, wash or be fixed by the soil to cause loss, the utilization rate is low, and it will be damaged after long-term use. Destroy soil structure and reduce crop quality
The overall disadvantages are uneven fertilizer nutrients, low content, short fertilizer period, poor dissolution, and low fertilizer utilization rate

Abstract

The invention discloses microgranular alginate water-soluble fertilizer prepared by means of melting complexation reaction, and a preparation method of the microgranular alginate water-soluble fertilizer. The microgranular alginate water-soluble fertilizer is prepared from the following raw material components in parts by weight: 60-80 parts of nitrogen fertilizer, 40-50 parts of phosphorus fertilizer, 70-80 parts of potassium fertilizer, 5-10 parts of an alginate synergistic solution, 10-15 parts of medium-trace element fertilizer, 3-5 parts of a mixture obtained by mixing calcium nitrate and calcium carbonate according to a mass ratio of 2 to 3, and 0.5-1 part of vegetable oil. The balance and stability of nutrient components of the fertilizer are guaranteed; nitrogen-phosphorus-potassium base fertilizer contains weak acid radicals, so that the complexation reaction is better promoted, and the fertilizer is easily absorbed by the crop root system; chelating medium-trace elements are easy to absorb; the calcium carbonate can improve the hardness of fertilizer microparticles and adjust the acid soil; the alginate synergistic solution contains small active substances and has an adhesive effect when being dissolved in water, so that the solubility of the microgranular alginate water-soluble fertilizer is better than that of the common water-soluble fertilizer after the alginate synergistic solution is complexed with molten nitrogen, phosphorus and potassium elements; the microgranular alginate water-soluble fertilizer is dissolved in a way of sol swelling, so that the fertilizer is convenient to disperse and absorb, and the crop yield is further increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizer equipment, and in particular relates to a microparticle alginic acid water-soluble fertilizer prepared through melt complexation reaction and a preparation method thereof. Background technique [0002] Fertilizers play a decisive role in the yield and quality of crops. Various types of compound (mixed) fertilizers currently used for crop growth have very low nitrogen, phosphorus, and potassium content in organic fertilizers. They mainly provide organic matter and other substances. Significant effect of soil improvement and fertilization; the types of nutrients contained are comprehensive, but the content is low, and the fertilizer strength is small; the fertilizer supply time is long, and the fertilizer effect is slow and long-lasting; it can fully integrate with the soil to form an organic complex, so the loss is small and the utilization rate is high. high. For inorganic fertilizers, it main...
