Problems solved by technology

The existing fertilizers are divided into inorganic fertilizers and organic fertilizers. Inorganic fertilizers are minerals or fertilizers processed through inorganic chemical reactions. Organic fertilizers are natural humus, human, livestock and poultry manure, industrial production or people’s daily life. Fertilizers processed from waste. Among them, the production technology of inorganic fertilizers is very mature. The existing inorganic fertilizers include urea, superphosphate, monoammonium phosphate or diammonium phosphate, potassium sulfate or potassium chloride, etc.; Fertilizer can be produced from the raffinate produced by various amino acids, glutamic acid, naphthalene amino acid, etc., and can also be obtained by fermenting and granulating fresh organic fertilizers. There are also patent applications disclosing the use of high-level peat or alcohol waste liquid dry powder and Bentonite, coal ash, industrial waste residue, etc. are used as raw materials to produce mixed organic fertilizers. The nutrients and efficacy of the fertilizers mentioned above are limited to a certain extent, and it is difficult to adapt to different crops and soil conditions. The existing mixing technology, It is also limited to the blending of various inorganic fertilizers. The use of organic organic materials is also greatly compromised in terms of biological safety and environmental protection due to the complexity of raw material sources, and the nutrient ratio of organic compound fertilizers can only be maintained at a low level. The quality is not high and cannot meet the needs of green food and organic agricultural production

Embodiment 1

[0016] Embodiment 1: the organic-inorganic compound fertilizer of 15% organic matter, 34% inorganic nutrient

[0017] The raw materials used in this example are:

[0018] Diammonium phosphate (N%=17.5; P 2 o 5 %=46.5): 141.5 kg

[0019] Urea (N%=46): 141.0 kg

[0020] Potassium sulfate (K 2 O%=49.5): 181.5 kg

[0021] Nai amino acid waste liquid organic fertilizer (organic matter%=28; amino acid=10%; N%=15; P 2 o 5 % = 0.08; K 2 O%=1.9): 536 kg

[0022] Put the above-mentioned production raw materials into the mixer through electronic metering or manual metering, and measure and pack after mixing evenly.

[0023] In the fertilizer industry, the organic matter content and the NPK content of inorganic nutrients are important indicators for evaluating the quality of fertilizers. The higher the content, the better the quality of the fertilizer, the greater its fertility when applied, and the more beneficial it is to the growth of crops. Detect organic matter and inorgani...

Embodiment 2 to Embodiment 10

[0025] Embodiment 2 to Embodiment 10: adopt the method identical with embodiment 1, select the raw material listed in table 1 for use.

[0026] Example

[0027] In Table 1, the numerical ranges expressed by each embodiment are respectively:

Abstract

A composite organic-inorganic fertilizer is prepared from the granular organic fertilizer (50-60 wt.%) and granular inorganic fertilizer (40-50 wt.%) through mixing, said organic fertilizer is prepared from the residual liquid generated in the production of amino acid, glutamic acid, etc. Its advantage is high fertility and complete nutrients.

Description

technical field [0001] The invention relates to fertilizers, in particular to a composite fertilizer comprising organic fertilizers and inorganic fertilizers. Background of the invention [0002] In agricultural production, fertilizer is an essential agricultural material. The existing fertilizers are divided into inorganic fertilizers and organic fertilizers. Inorganic fertilizers are minerals or fertilizers processed through inorganic chemical reactions. Organic fertilizers are natural humus, human, livestock and poultry manure, industrial production or people’s daily life. Fertilizers processed from waste. Among them, the production technology of inorganic fertilizers is very mature. The existing inorganic fertilizers include urea, superphosphate, monoammonium phosphate or diammonium phosphate, potassium sulfate or potassium chloride, etc.; Fertilizer can be produced from the raffinate produced by various amino acids, glutamic acid, naphthalene amino acid, etc., and can ...
