Embodiment 2

[0039] Implementation 2 inorganic fertilizer

[0040] Formula (parts by weight): 36 urea, 28 monoammonium phosphate, 19 potassium chloride, 22 lime nitrogen, 23 magnesium ammonium phosphate, 18 zinc sulfate, 1 boric acid, 6 fungicides, 25 urea formaldehyde, 12 diatomaceous earth, thio Ammonium sulfate 0.2 and dicyandiamide 0.2; the above raw materials are all passed through a 200-mesh sieve.

[0041] The content of each raw material: monoammonium phosphate (N11%, P 2 o 5 44%), potassium chloride (K 2O≥60%), urea (N≥46%), lime nitrogen (N≥11%), magnesium ammonium phosphate, nitrogen 11-16%, phosphate 8-12%.

[0042] Preparation:

[0043] (1) Stir and mix urea, monoammonium phosphate, potassium chloride, lime nitrogen, magnesium ammonium phosphate, zinc sulfate, boric acid and fungicide;

[0044] (2) Ammonium thiosulfate, dicyandiamide and urea-formaldehyde are dissolved in water, and the raw materials mixed in step (1) are sprayed under high pressure, and enter the granula...

Embodiment 3

[0046] Embodiment 3 organic fertilizer

[0047] Formula (parts by weight): fungicide dregs 6, chicken manure 8, bagasse 4, xylitol dregs 4, cottonseed cake 6 and plant ash 1. Wherein, the water content of each raw material is less than 25%.

[0048] The preparation method is as follows: uniformly mix fungicide dregs, chicken manure, bagasse, xylitol dregs, cottonseed cake and plant ash to form a mixture, then add water to adjust the water content to 50-60wt%, and then spray into the total mass of raw materials 0.1% stock solution of EM bacteria is piled up and fermented in the open air; during the fermentation process, when the temperature of the pile rises to 50°C, the pile starts to turn. So repeated (maintain water content is 50~60wt%), after fermenting 7-10 days, can be used as organic fertilizer and use. Airing or drying the piled and fermented organic fertilizer until the water content is ≤20wt%, and then granulating by dry powder extrusion granulation method, the orga...

Embodiment 4

[0049] Embodiment 4 use effect

[0050] The application method of the present invention: according to the mass ratio of the organic fertilizer and the inorganic fertilizer being 2:8, the inorganic fertilizer of the embodiment 2 and the organic fertilizer of the embodiment 3 are prepared into a special machine fertilizer for rice. Apply 55 kg of this fertilizer per mu.

[0051] Further illustrate its beneficial effect in conjunction with comparative experiment below.

Abstract

The invention discloses a fertilizer specially used for rice and a preparation method thereof. The fertilizer comprises an organic fertilizer and an inorganic fertilizer, wherein the inorganic fertilizer is prepared from the following raw materials: urea, monoammonium phosphate, potassium chloride, lime nitrogen, magnesium ammonium phosphate, zinc sulfate, boric acid, a sterilizing agent, urea formaldehyde, diatomite, ATS and dicyandiamide; the urea formaldehyde containing ammonium thiosulfate and dicyandiamide serves as a coating, and the diatomite is attached to the outer side of the coating; the other raw materials are contained in the coating. The organic fertilizer is prepared from the following raw materials: sterilizing agent decoction dregs, chicken manure, bagasse, xylitol residue, cottonseed cake and plant ash. The fertilizer can meet the requirement of the whole rice growth period after being applied once, manual labor is saved, the soil aeration, fertilizer absorption and water retention characteristics can be improved, steady growth of rice plants is promoted, and the yield is increased by 10-20 percent per mu.

Description

technical field [0001] The invention relates to a special fertilizer for rice and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Rice is one of the most important food crops in the world. With the rapid increase of the global population, increasing rice production has become an urgent issue. Among them, fertilizer plays an important role in improving the yield of rice. Reasonable fertilization, on the one hand, can coordinate the contradiction between rice growth's demand for nutrient elements and soil fertilizer supply, so as to achieve high yield and high quality; on the other hand, less fertilizer input can be used to obtain higher yield and maximum economic benefits , to achieve the purpose of saving costs and increasing efficiency. [0003] According to relevant statistics, the input of chemical fertilizers accounts for about 50% of the total input of farmers in planting production, and 50% of the increase...
