specific Embodiment approach 1

[0019] Specific embodiment one: a kind of organic-inorganic compound fertilizer with biomass charcoal as the matrix in this embodiment, according to the mass parts, consists of 25-30 parts of straw biomass fine charcoal powder, 15-30 parts of nitrogen fertilizer, 15-30 parts of Phosphate fertilizer, 10-25 parts of potassium fertilizer, 5-10 parts of bentonite, binder and 0-2 parts of trace elements, wherein the binder is 0.1-0.3 parts of xanthan gum or 1-2 parts of oxidized starch.

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the straw in the straw biomass fine charcoal described in step 1 is corn straw, soybean straw, rice straw or wheat straw. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific embodiment three: this embodiment is different from one of specific embodiments one to two in that the nitrogen fertilizer described in step three is one or more of urea, ammonium sulfate, ammonium chloride, monoammonium phosphate or diammonium phosphate Mix in any proportion. Others are the same as one of the specific embodiments 1 to 2.

[0022] The type and amount of nitrogen fertilizer added in this embodiment are added according to the different types of crops. When the crops are corn, the nitrogen fertilizer applied is urea; when the crops are potatoes, the nitrogen fertilizer applied is urea; when the crops are soybeans At the same time, the nitrogen fertilizer applied is monoammonium phosphate and diammonium phosphate, and the mass ratio is 1:0.5~2.

[0023] Specific embodiment four: the difference between this embodiment and one of specific embodiments one to three is that the phosphate fertilizer described in step 3 is one of diammonium phosphate, mo...

Abstract

The invention discloses an organic / inorganic compound fertilizer taking biomass charcoal as a matrix, a preparation method of the organic / inorganic compound fertilizer and a preparation method of fine straw biomass charcoal powder, relates to a compound fertilizer, a preparation method thereof and a preparation method of biomass charcoal and aims to solve the problems that the compound fertilizer is high in raw material cost, poor in granulation, capable of causing straw resource waste and low in utilization ratio and the energy consumption in the production process of the fine straw biomass charcoal powder is high. The fertilizer disclosed by the invention is prepared from fine straw biomass charcoal powder, a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer, bentonite, a binder and trace elements; the preparation method of the fertilizer disclosed by the invention comprises the steps: firstly, preparing biomass charcoal; and secondly, smashing and screening; and the preparation method of the fertilizer disclosed by the invention comprises the steps: firstly, weighting the fine straw biomass charcoal powder and other raw materials; secondly, pretreating an inorganic fertilizer raw material; thirdly, mixing; and fourthly, granulating and drying to obtain organic / inorganic compound fertilizer grains taking the biomass charcoal as the matrix. The preparation method of the organic / inorganic compound fertilizer is applied to the technical field of fertilizer production.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and mainly relates to a method for preparing organic-inorganic compound fertilizer and straw biomass fine carbon powder. Background technique [0002] At present, as an important part of increasing the nutrient elements of crops, chemical fertilizers play a key role in increasing the yield of crops. However, the continuous increase and unreasonable use of chemical fertilizers have brought a series of problems to the development of modern agriculture. Long-term excessive application of chemical fertilizers will destroy the stability of soil structure and even lead to acidification of soil. After acidification of soil, Ca, Elements such as Mg are leached from the cultivated layer, thereby reducing the base saturation and soil fertility, resulting in low utilization rate of chemical fertilizers. With the rise of sustainable ecological agriculture and people's concerns about soil pollu...
