Embodiment 1
[0027] A kind of preparation method of novel fertilizer:
[0028] (1) Desalination: the concentration of bittern is above 30°Bé, heated to 90°C for 2 hours to remove the crystals, and during the constant temperature process of 90°C, the sodium chloride in bittern will crystallize and precipitate rapidly. The precipitation process will cause the crystallization of sodium chloride in the bittern that cannot be crystallized due to salt production to precipitate and further remove the salt. The constant temperature at 90°C is controlled for 2 hours so that a very small amount of sodium chloride remains in the bittern;
[0029] (2) Chlorine removal: Make the liquid concentration of removing crystals reach Baume degree more than 28 DEG B é, leave standstill for 96 hours after natural cooling, remove crystals, in the standing process liquid, magnesium chloride produces crystal precipitation and removes;
[0030] (3) bromine removal: take out the supernatant liquid from the liquid tha...
Embodiment 2
[0034] The key element content of the novel fertilizer prepared in Example 1 is as described in Table 1: (measurement condition: 26° C.)

[0036]
Embodiment 3
[0038] The novel fertilizer that embodiment 1 prepares is applied to the effect embodiment of seedling:
[0039] The late rice Xieyou 3550 and the early rice Teyou 524 were selected as test crops, and plastic floppy disks were used to raise seedlings, and multi-point plots were compared in Licuo Village, Qiandong Town, Raoping County, with an area of 6M 2 , repeated three times, with protective rows around. From February 9th, 2014, implement the following treatments respectively: seed dressing buds or spraying, no seed dressing buds or no spraying as contrast (wherein, no seed dressing or no spraying is used as CK), the seedling raising soil is pond mud, and the top is covered Sieve sandy soil, its specific treatment method:
[0040] A. For one mu of field, use 100g of new fertilizer and 50kg of water to mix with the seed buds, and then sow after drying in the shade;
[0041] B. Spray 100g of new fertilizer and 50kg of water for one mu of field in the three-leaf stage (car...

Abstract
The invention discloses a novel fertilizer and a preparation method thereof. The preparation method comprises the following steps: (1) desalting, namely ensuring the concentration of bitter bittern to reach the baume degree of more than 30 degree Be, heating to 90 DEG C, maintaining constant temperature for 2 hours, and removing crystals; (2) performing dechlorination, namely enabling the concentration of liquid of which the crystals are removed to reach the baume degree of more than 28 degree Be, naturally cooling, then standing for 96 hours, and removing the crystals; (3) removing bromine, namely removing supernatant liquid; (4) drying; and (5) adding nitrogen phosphorus potassium. According to the novel fertilizer disclosed by the invention, a fertilizer suitable for agriculture and forestry is produced by using the bitter bittern, and the novel fertilizer is easily-available in raw material, low in cost and significant in economic benefit. The fertilizer produced by using the method disclosed by the invention is multifunctional, can be used as an additional fertilizer, can also be used as an external root fertilizer, can also be used as a base fertilizer, can be used for preventing soil hardening after being used, and ensures that the soil fertility can be improved by using various micro-elements and medium elements in the fertilizer; and compared with conventional inorganic chemical fertilizers, the fertilizer disclosed by the invention has the advantages of low cost, good action aftereffect, no soil hardening, rapid crop growth and good quality achieved after the fertilizer is used, improved soil fertility and significant sustainable soil property.
Description
technical field [0001] The invention relates to the field of fertilizers, in particular to a novel fertilizer and a preparation method thereof. Background technique [0002] In the process of salt production, the seawater is concentrated by the sun and salt is precipitated. When the brine reaches a certain concentration, the salt is no longer exposed to the sun, and the brine is called bittern. Bittern is a by-product of the salt-making process and is mostly discarded. There are a lot of natural bittern in some natural salt lakes, and the waste liquid is also used as waste after human beings extract potassium, magnesium, sodium and bromide salts, such as the Dead Sea in Palestine, Kara Begaz Lake in the former Soviet Union, Canada's Goodenough Lake, etc., as well as Jiangcheng Salt Mine in Simao, Yunnan, Yingcheng Salt Mine in Hubei, Zhangshu Salt Mine in Jiangxi, Zigong Salt Mine in Sichuan, and Qinghai Salt Lake all have a large amount of natural brine resources. Most of...
