Embodiment 1

[0030] In this example, the percentages of the components in the total weight of nitrogen fertilizer are: amino acid 2.5%, ammonium nitrogen 24%, and organic nitrogen 1.5%. Hereinafter referred to as amino acid nitrogen fertilizer I.

Embodiment 2

[0032] In this example, the percentages of each component in the total weight of nitrogen fertilizer are: amino acid 10%, ammonium nitrogen 20%, and organic nitrogen 2.0%. Hereinafter referred to as amino acid nitrogen fertilizer II.

[0033] The following is a comparative experiment for the nitrogen fertilizers of the components described in the above examples.

[0034] 1. The experiment of raising fish with amino acid nitrogen fertilizer was carried out at Wang Hongjia, Group 5, Baling Development Zone, Dangyang City, Hubei Province.

[0035] Wang Hong has a pond of 8.2 mu, a pond of 2.5 mu, and a pond of 10.3 mu. The water depth is 2 meters. The fish fry are 50 silver carp + 300 silver carp, and the fry are about 0.15 to 0.2 kg.

[0036] 2.5 mu ponds are fertilized by 7.5 kg of ammonium bicarbonate + 7.5 kg / mu of phosphate fertilizer, once every 7 days.

[0037] The 8.2-mu pond is fertilized by 5.0 kg / mu of amino acid nitrogen fertilizer I + 7.5 kg / mu of phosphate fertili...

Embodiment 3

[0051] In this embodiment, the percentages of the components in the total weight of the nitrogen fertilizer are: amino acid 15%, ammonium nitrogen 18%, and organic nitrogen 3.0%. Hereinafter referred to as amino acid nitrogen fertilizer III.

[0052] Compared with amino acid nitrogen fertilizers I and II, amino acid nitrogen fertilizer III has higher amino acid content and lower ammonium nitrogen content.

[0053] The test to verify the effect of this embodiment is divided into two:

[0054] 1. It was carried out in the paddy field of Zhou Baocai, the head of the fishery station of Makou Station, Gongan County, Hubei Province.

[0055] For shrimp farming in paddy fields, amino acid fertilizer III was used, and the amount per mu was 25 kg.

[0056] The result is as follows:

[0057] ① Amino acid nitrogen fertilizer III is safe and has no adverse effect on shrimp growth.

[0058] ②The rice grows well, and there is no shortage of nitrogen supply. It is proved that the applic...

Abstract

The invention relates to an amino acid nitrogenous fertilizer and the production method which aims at the problems that the prior technique for fertilizer preparation is quite complex and the fertilizer causes negative effect on the environment and the soil and the problem that the fertilizer has a low utilization ratio. The invention provides an amino acid nitrogenous fertilizer consisting of three ingredients: amino acid, ammonium nitrogen and organic nitrogen. The above amino acid nitrogenous fertilizer production method is shown as follows: the keratin acidolysis law decomposes the keratin and produces the amino acid; the waste water in the production of amino acid gets neutralized by liquid ammonia to the alkaline nature, and then crystallized and filtrated. The filtration solution is sprayed and dried; after duplicate matches, the amino acid is selectively added. The nitrogenous fertilizer of the invention has the advantages of low cost, quick fertilizer effect, long-lasting fertilizer effect and enhancing such abilities of crops as anti water logging, anti-drought, anti-coldness and anti-pesticide. Moreover, the nitrogenous fertilizer production method, being easy, environment-friendly and easily operated, has the advantage of greatly reducing the cost, thus the promotion and the application are benefitted.

Description

technical field [0001] The present invention relates to a nitrogen fertilizer and a production method thereof. Background technique [0002] At present, the nitrogen fertilizers in chemical fertilizers mainly include ammonium bicarbonate, ammonium sulfate, urea, and ammonium chloride. Their production process is mainly to use coal to burn, extract nitrogen from the air, and then gradually convert it. The problems they have are that they are easy to have adverse effects on the environment and soil, and the utilization rate of fertilizers is low. [0003] People are trying to find an environmentally friendly nitrogen fertilizer containing amino acids, hoping to use it on farmland and aquatic products. But are nitrogen fertilizers containing amino acids stable? Can amino acids be used directly on farmland? How much? Is it easy to use? How to deal with wastewater from amino acid production? What nutrients do farm crops need? What kind of nutrients do fish and shrimp aquat...
