Embodiment 1

[0037] Take the manufacture of slow-release organic and inorganic nitrogen fertilizers with a nitrogen content of 25.3% as an example:

[0038] Get nitrogen nutrient content and be 46% urea 55%, 200 purpose slow-release organic mud powder 38%, 500 purpose slow-release organic coating powder 5%, anti-caking agent 2% (mixing during coating).

[0039]

[0040] After the urea is pulverized and mixed with the slow-release organic mud powder, it is sent to the granulator for granulation. After granulation, take the slow-release organic coating powder and anti-caking agent and mix it and send it into the coating machine for coating. After the film is wrapped, send it to the dryer according to the conventional process for manufacturing granular fertilizers (the same as in the following examples) Drying, cooling, sieving, packaging, the finished product.

Embodiment 2

[0042] Take the manufacture of slow-release organic and inorganic potassium fertilizers with a potassium fertilizer nutrient content of 30% as an example:

[0043] Get potassium nutrient content and be 60% potassium fertilizer 50%, 200 purpose slow-release organic mud powder 46%, 500 purpose slow-release organic coating powder 2%, anti-caking agent 2% (mixing during coating). After the potash fertilizer is crushed and stirred evenly with 200 mesh slow-release organic mud powder, it is sent to the granulator for granulation. After the granulation is completed, the slow-release organic coating powder and anti-caking agent are mixed and sent to the coating machine. Carry out film coating, after the film is wrapped, send it to the dryer for drying, then cool, sieve, pack, and become the finished product.

[0044]

Embodiment 3

[0046] Take the formulation of slow-release organic and inorganic compound fertilizers with a nutrient content of 20.1% as an example:

[0047] Take 46% of urea nutrients, 32% of nitrogen fertilizers with 25% of ammonium chloride nutrients, 10% of ammonium phosphate with 40% of ammonium phosphate nutrients, 10% of potassium chloride with 60% of potassium chloride nutrients, 33% of slow-release organic mud powder, and slow-release organic mud powder. Release organic fertilizer powder 12%, slow release organic shellfish powder 3%. After crushing nitrogen, phosphorus and potassium fertilizers, mix them with 200-mesh slow-release organic mud powder, 100-mesh slow-release organic fertilizer powder and 100-mesh slow-release organic shellfish powder, and then send them to the granulator for granulation. After drying, cooling, sieving, packaging (this embodiment does not coat).

Abstract

The present invention provides slowly released organic and inorganic fertilizer, and belongs to the field of agricultural production technology. It consists of mainly slowly released organic mud fertilizer comprising pond sludge and clay, slowly released organic fertilizer powder, slowly released organic coating agent, slowly released organic bone-shell powder, anti-caking agent, nitrogen fertilizer, phosphate fertilizer and potash fertilizer. It is granular fertilizer produced through mixing, adsorption and coating. The nitrogen fertilizer, phosphate fertilizer and potash fertilizer are coated for slowly releasing. The fertilizer has raised utilization and soil improving effect.

Description

Technical field: [0001] The invention relates to a slow-release organic powder and slow-release organic and inorganic fertilizers, belonging to the field of agricultural production materials. Background technique: [0002] With the change of modern agricultural production methods, in order to greatly increase the yield, people's habitual practice is to rely on the application of a large amount of chemical fertilizers, and it has indeed been proved that the yield per acre of crops can be greatly increased. But now when people apply chemical fertilizers in the field, they generally adopt the methods of spreading, hole application and strip application, and the chemical fertilizers are directly applied to the farmland. However, the utilization rate of chemical fertilizers directly applied to farmland is low, and most of the fertilizers are consumed due to volatilization, penetration and loss. For example, the utilization rate of nitrogen fertilizer is about 33%, the utilizatio...
