Embodiment 1

[0025] Embodiment 1, present embodiment provides a kind of organic slow release fertilizer of improving soil

[0026] First weigh 20kg of humic acid; 5kg of seaweed; 15kg of rice husk biochar; 15kg of urea; 8kg of nitrogen fertilizer; 6kg of potassium fertilizer; Calcium aspartate 10kg, then, after mixing humic acid, seaweed, rice husk biochar, urea, nitrogen fertilizer, potassium fertilizer, phosphate fertilizer and polyaspartate calcium, add brown sugar water, stir well, and stir into a viscous It can be thickened, granulated, and the mother nucleus is obtained for use. The ratio of brown sugar and water in brown sugar water is 6:100. The purpose of choosing brown sugar water is mainly to provide a certain viscosity and bind the raw materials together. In this embodiment , the particle size is between 1mm and 1.5mm.

[0027] Then, the animal fat is indirectly heated and melted by steam, and then pumped into the coating drum by the metering oil pump, and the mother core is p...

[0030] Embodiment 2, present embodiment provides a kind of organic slow release fertilizer of improving soil

[0031] First weigh 40kg of humic acid; 10kg of seaweed; 25kg of rice husk biochar; 25kg of urea; 10kg of nitrogen fertilizer; 9kg of potassium fertilizer; Calcium aspartate 15kg, then, mix humic acid, seaweed, rice husk biochar, urea, nitrogen fertilizer, potassium fertilizer, phosphate fertilizer and calcium polyaspartate evenly, add brown sugar water, stir to become viscous Yes, stir evenly, granulate, and obtain the mother nucleus for use. The ratio of brown sugar and water in brown sugar water is 6:100. The purpose of choosing brown sugar water is mainly to provide a certain viscosity and bind the raw materials together. In this embodiment , the particle size is between 1mm and 1.5mm.

[0032] Then, the animal fat is indirectly heated and melted by steam, and then pumped into the coating drum by the metering oil pump, and the mother core is poured into the coatin...

Embodiment 3

[0034] Embodiment 3, present embodiment provides a kind of organic slow release fertilizer of improving soil

[0035]First weigh 30kg of humic acid; 8kg of seaweed; 22kg of rice husk biochar; 20kg of urea; 9kg of nitrogen fertilizer; 8kg of potassium fertilizer; Calcium aspartate 12kg, then, after mixing humic acid, seaweed, rice husk biochar, urea, nitrogen fertilizer, potassium fertilizer, phosphate fertilizer and polyaspartate calcium, add brown sugar water, stir well, and stir into a viscous Just thick. Granulate to obtain the mother nucleus for use. The ratio of brown sugar and water in brown sugar water is 6:100. The purpose of selecting brown sugar water is mainly to provide a certain viscosity and bind the raw materials together. In this embodiment, the particle size is 1mm ~1.5mm.

Abstract

The invention belongs to the field of processing and preparation of organic fertilizer, and in particular relates to organic slow-release fertilizer with a function of improving soil, and a preparation method of the organic slow-release fertilizer. The organic slow-release fertilizer is prepared from the following components: 20-40 parts of humic acid, 5-10 parts of algin, 15-25 parts of rice huskbiochar, 15-25 parts of urea, 8-10 parts of nitrogen fertilizer, 6-9 parts of potassium fertilizer, 8-12 parts of phosphorus fertilizer, 5-10 parts of hydrogel, 3-5 parts of nitrogen fixing agent, 3-5 parts of animal oil, 3-5 parts of adhesive and 10-15 parts of calcium polyaspartate. The organic slow-release fertilizer with the function of improving soil and the preparation method of the organicslow-release fertilizer utilize the characteristics of the humic acid, the algin, the rice husk biochar and the calcium polyaspartate to further effectively improve the soil, thus increasing the absorption efficiency of plants; furthermore, in combination of preparation of the hydrogel, the nutrients are slowly released, so that the aims of improving the soil quality for a long time and increasing the absorption efficiency of crops are further achieved.

Description

technical field [0001] The invention belongs to the field of organic fertilizer processing and preparation, and in particular relates to an organic slow-release fertilizer for improving soil and a preparation method thereof. Background technique [0002] Soil is the basis for the survival and development of human beings. Soil fertility is the basis for high agricultural yields. The main way to improve soil fertility is to apply fertilizers. Fertilizers are the key to stable, high-yield, high-efficiency, high-quality, and healthy development of agriculture. Due to the long-term partial application of a large amount of elemental chemical fertilizers in the soil, many problems have arisen, such as single soil nutrients, damage to the soil aggregate structure, and soil compaction, resulting in serious soil degradation and quality decline. The non-renewable and usable land resources are gradually withered and brown, which will seriously affect agricultural production and human su...
