Problems solved by technology

There have also been domestic precedents of using these wastes from food production to make organic fertilizers, but most of them have not undergone biological fermentation or the fermentation is not complete, resulting in many unfavorable results. First, the products made contain toxic and harmful substances, which pollute the environment; second, Most of the existing production processes use mechanical mixing or simple extrusion, resulting in poor product form; third, due to incomplete fermentation, the nutrient content of the product is not high, which cannot meet the nutritional needs of crops

Embodiment 1

[0031] The fertilizer of this embodiment is composed of the following raw materials and their weight percentages: molasses fermentation liquid: 78%, biochemical fulvic acid: 10%, base material: 12%; wherein, the base material is diamine hydrogen phosphate;

[0032] The preparation method of above-mentioned high-efficiency organic granular fertilizer comprises the following steps:

[0033] 1) Pre-lay the base material in the spray granulation fluidized bed 1, and the air is heated to 1200°C by the direct-fired coal-fired hot air stove 2, and then enters the bottom of the spray granulation fluidized bed 1 through the first hot air blower 3, and passes through the distribution plate Contact with the primer and make the primer fluidized.

[0034] 2) Utilize the first feed liquid pump 4 to deliver the molasses fermented liquid from the first feed liquid port 5 to the atomizing nozzle, make it sprayed on the surface of the bottom material particles in the fluidized state after atomi...

Embodiment 2

[0042] The difference between this example and Example 1 is that the weight percentages of raw materials used are different, and the preparation method is the same. The raw materials and their weight percentages are as follows: molasses fermented liquid: 10%, biochemical fulvic acid: 20%, base material: 70%, wherein, the base material is farmyard manure.

[0043] The organic matter content of the high-efficiency organic granular fertilizer obtained in this embodiment is 46%, the total content of nitrogen, phosphorus pentoxide, and potassium oxide is more than 8%, and the moisture content is 2.7%, which is far superior to the national organic fertilizer standard. The application tests of different crops prove that the effect of increasing yield and improving quality can reach the effect of Example 1, and the effect of this embodiment is more obvious for melons, fruits and vegetables.

Embodiment 3

[0045]The difference between this example and Example 1 is that the weight percentages of the raw materials used are different, the base material is the small particle fertilizer separated in Example 1 with a particle diameter within 2mm, and the preparation method is the same.

[0046] The raw materials and their weight percentages are as follows: molasses fermented liquid: 40%, biochemical fulvic acid: 40%, base material: 20%.

[0047] This embodiment can also achieve the effect of Embodiment 1.

Abstract

The invention discloses a high-efficiency organic granulated fertilizer and a preparation method thereof. The fertilizer comprises the following raw materials in percentage by weight: 10-78% of molasses fermentation liquid, 10-40% of fulvic acid and 10-70% of substrate, wherein the sum of the percentage of the raw materials is 100%. The preparation method of the fertilizer of the invention comprises the following steps of: laying the substrate in a spray granulation fluidized bed (1), and spraying the substrate with the atomized molasses fermentation liquid; discharging granules with the granularity of 2-4mm; recovering the fluidized and atomized fine powder by using a cyclone separator to be used as a new substrate; continuously spraying the granules with the atomized fulvic acid in a rotary granulator (7); and cooling finished products, and then packing the finished products. The fertilizer of the invention has high content of organic nutrients, and the absorption ratio and the utilization ratio reach more than 90%; the fertilizer is suitable for various kinds of soils and can obviously increase the yield and improve the quality of various kinds of plants, wherein the yield of grain crops can be increased by more than 15%, the yield of cash crops can be increased by more than 20%, and the yield of vegetables can be increased by more than 20%; and the fertilizer is a preferred product for producing organic green foods.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology, and in particular relates to a preparation method of high-efficiency organic granular fertilizer. Background technique [0002] In sugar and other food production processes, a large amount of waste is produced, many of which are not utilized, which not only causes environmental pollution, but also causes a great waste of resources. In fact, these food production wastes contain a lot of nutrients, and after biological fermentation, they can be turned into bio-organic fertilizers with high utilization value. There have also been domestic precedents of using these wastes from food production to make organic fertilizers, but most of them have not undergone biological fermentation or the fermentation is not complete, resulting in many unfavorable results. First, the products made contain toxic and harmful substances, which pollute the environment; second, Most of the existing production proc...
