Problems solved by technology

However, due to the low technical content of chemical fertilizer products, poor fertilization technology and low fertilizer utilization rate, especially the seasonal utilization rate of nitrogen fertilizer is less than 35%, which caused huge economic losses and obvious environmental pollution.
With the development of straw returning to the field in recent years, the utilization rate of straw has increased, but the comprehensive utilization of straw still has problems such as low utilization rate, short industrial chain and unreasonable industrial layout.

preparation example Construction

[0029] The preparation method of the novel fertilizer described in this application is a preparation method well known to those skilled in the art, that is, ordinary fertilizers and fertilizer additives are mixed and granulated in a certain proportion.

[0030] The new fertilizers described in this application include fertilizers and fertilizer additives. Because fertilizer additives can absorb fertilizer nutrients, they can fix nitrogen, phosphorus, and potassium around the roots of crops to supply crop growth needs. At the same time, they can also improve soil, increase soil organic matter, and absorb nutrients. Fix harmful components such as heavy metals, antibiotics, and pesticide residues in the soil to improve crop quality. Fertilizer bio-auxiliaries are preferably compounded by biochar, crop growth active factors, nitrogen regulators, polymer materials, and trace elements in a certain proportion; new fertilizers containing fertilizer auxiliaries can not only increase fer...

Embodiment 1

[0033] A kind of fertilizer, including common fertilizer and fertilizer additive, wherein in common fertilizer, in nitrogen fertilizer, phosphorus fertilizer and potash fertilizer, N:P 2 o 5 :K 2 The weight ratio of O is 22:6:12; Specifically, in terms of weight percentage, ammonium chloride accounts for 25%, urea accounts for 30%, ammonium bicarbonate accounts for 4.5%, ammonium sulfate accounts for 2.5%, monoammonium phosphate accounts for 15%, Potassium chloride accounts for 21%, and fertilizer additives account for 2%. The fertilizer additives include: wheat straw charcoal 50%, clay minerals: kaolin 40%, crop growth active factor: sodium nitrophenolate 1%, nitrogen regulator : Thiourea 0.5%, DMBP 1%, polymer material: polyacrylamide 0.5%, polyglutamic acid 1%, trace elements: copper sulfate 3% and boric acid 3%. The above-mentioned various components are mixed and granulated according to the proportional relationship to obtain the fertilizer.

Embodiment 2

[0035] A kind of fertilizer, including common fertilizer and fertilizer additive, wherein in common fertilizer, in nitrogen fertilizer, phosphorus fertilizer and potash fertilizer, N:P 2 o 5 :K 2 The weight ratio of O is 15:15:20; Specifically, in terms of weight percentage, ammonium chloride accounts for 8%, urea accounts for 22%, monoammonium phosphate accounts for 32%, potassium chloride accounts for 32%, bentonite accounts for 1%, Sodium silicate accounts for 2%, fertilizer additives account for 3%; said fertilizer additives include: wheat straw charcoal 35%, clay mineral: bentonite 45%, crop growth active factor: potassium fulvic acid 8%, nitrogen regulator : Hydroquinone 1%, Thiourea 2%, Polymer Materials: Polyvinyl Alcohol 1.5%, Polyacrylamide 0.5%, Trace Elements: Boric Acid 3% and Zinc Sulfate 4%. The above-mentioned various components are mixed and granulated according to the proportional relationship to obtain the fertilizer.

Abstract

The invention provides an efficient fertilizer containing biomass charcoal. The efficient fertilizer comprises manure and a manure additive, wherein the manure additive comprises biomass charcoal, active crop growth factors and a polymer material. The invention provides the low-cost, efficient and environment-friendly novel fertilizer which can be used for improving the soil structure, increasing the organic matters in soil and regulating the microenvironment of soil while increasing the utilization ratio, and furthermore, the risk that harmful substances such as heavy metals enter edible parts of crops is reduced, and the quality of the crops is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a high-efficiency fertilizer containing biochar. Background technique [0002] From the development of agriculture to the middle of the 20th century, the world’s arable land has grown simultaneously with the population, and the growth of food supply has almost entirely depended on the expansion of arable land. After 1950, the growth rate of the world’s arable land has gradually fallen below the growth rate of the population. In China, the application of chemical fertilizers has become the main means to increase the yield per unit area. "Father of the Green Revolution" N.E.Borlaug concluded after analyzing the factors related to the development of agricultural production in the 20th century that half of the world's crop production increase in the 20th century came from the application of chemical fertilizers. Therefore, fertilizer is the "grain" of food, and it is impossibl...
