Problems solved by technology

However, in reality, after the slow-release fertilizer is fertilized, it will be washed away by the rain, causing the fertilizer to be lost with the rain, resulting in a waste of fertilizer, so that the fertilizer effect cannot be maintained for several months in the rainy season.

Abstract

The invention discloses slow-release type organic granular fertilizer and a preparation method thereof. The slow-release type organic granular fertilizer is prepared from the following raw materials:straw, earthworm cast, animal manure, vermiculite, plant ash, trace element solution, kaolin, montmorillonite and a slow-release additive. The preparation method comprises the following steps of: 1) mixing the straw, the earthworm cast, the animal manure, the vermiculite and the plant ash and fermenting; 2) after fermentation is ended, sieving out completely-composted powder and granules, pouringinto a container, adding the trace element solution and carrying out high-pressure electrostatic treatment; 3) after mixing and crushing the kaolin and the montmorillonite and mixing with treated powder and granules, carrying out oscillatory rotation in a vacuum container, and using a high-pressure jet pump to spray the slow-release additive into the container; 4) placing the materials in the step3) into a granulating machine, and drying to prepare the fertilizer. The slow-release type organic granular fertilizer disclosed by the invention has the beneficial effects that the preparation process is simple, the operation is easy, the fertilizer can be effectively bonded and combined with soil together after being applied, so that the fertilizer loss caused by rain wash is reduced and the utilization rate of the fertilizer is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a slow-release organic granular fertilizer and a preparation method thereof. Background technique [0002] Slow-release fertilizers are also called slow-release fertilizers or controlled-release fertilizers. The compounds containing nutrients in the fertilizers are released slowly in the soil or the release rate of nutrients can be controlled to a certain extent for the continuous absorption and utilization of crops. The use of slow-release fertilizers can reduce the loss of fertilizer nutrients, especially nitrogen, in the soil, reduce the number of fertilization operations, save labor and costs, and at the same time avoid damage to seeds or seedlings caused by excessive fertilization. [0003] Slow-release fertilizers can slowly release effective nutrients and maintain long-term nitrogen fertilizers. The most important feature of slow-release nitrogen ...
