Problems solved by technology

[0002] Furfural slag, as a waste produced in the process of biomass hydrolysis, has a high salt content and is acidic, and its large accumulation will pollute the atmosphere, soil, and rivers; as a biomass waste, furfural slag contains a large amount of cellulose, Hemicellulose and lignin have good reuse value. For example, they can be used to increase land fertility after treatment. However, the existing furfural slag is not completely purified during the use process. In addition to increasing land fertility, it still It will cause certain land pollution problems, and there are advantages and disadvantages in the process of use. Therefore, a panicle fertilizer and its application method for large-area and balanced production of rice are now provided.

preparation example Construction

[0018] The preparation method of the activated furfural slag comprises the following steps: (1) selecting and crushing crop straws to a particle size of 20mm-30mm to obtain crop straw powder; (2) mixing the crushed crop straw powder with a mass concentration of 10-30mm 15% sulfuric acid solution is mixed according to the mass ratio of 0.3-0.5:1 to obtain the sulfuric acid powder mixture; (3) The water vapor is contacted with the sulfuric acid powder mixture for hydrolysis, and the water vapor enters from the lower part of the sulfuric acid powder mixture and is discharged from the upper part. The steam temperature is 150°C-200°C, and the hydrolysis time is 1-2h; (4) The sulfuric acid powder mixture after hydrolysis is furfural slag; (5) KOH solution and furfural slag are mixed according to the mass ratio of 1:1, Immerse at room temperature for 5 hours, and the mass concentration of KOH solution is 20%-40%; (6) Dry the impregnated furfural slag until there is no free water; (7) ...

Abstract

The invention discloses a rice panicle fertilizer capable of realizing large-area balanced yield increase and an application method thereof, and relates to the field of rice panicle fertilizer. A monosultap component is added in the rice panicle fertilizer, so that insect pests can be prevented and controlled while the fertilizer is applied, and the yield increase effect is better; the furfural residues are used as waste generated in the biomass hydrolysis process, are high in salt content and acidic, and can pollute the atmosphere, soil and rivers when being accumulated in a large amount; in the prior art, the furfural residue is used as a biomass waste, contains a large amount of cellulose, hemicellulose and lignin, and has good reutilization value, for example, the furfural residue is used for increasing the soil fertility after being treated. However, in the using process of existing furfural residues, due to the fact that treatment and purification are not thorough, certain land pollution problems can still be caused besides land fertility increase, and the furfural residues have advantages and disadvantages in the using process. Therefore, the furfural residues are treated and activated, so that the effect of increasing the land fertility is improved while the negative influence of the furfural residues is reduced.
