[0026] An organic selenium fertilizer for selenium-enriched rice paddy is prepared by the following steps:

[0027] S1. Degrease the selenium-enriched rice bran, add 0.5 mol / L sodium dihydrogen phosphate to soak for 1 hour, heat up to 20°C, shake at a speed of 400r / min for 2 hours to obtain material 1;

[0028] S2. Add selenium-enriched yeast to the material 1 obtained in S1, heat to 32°C and stir for 10 minutes. After cooling, add humate and linoleic acid to obtain material 2. Mix material 2 with a granulating agent and pulverize it and send it to granulation Granulate in the machine to obtain granule 1;

[0029] S3, uniformly mix nitrogen fertilizer, potassium fertilizer, phosphate fertilizer, urease inhibitor, and ammonia stabilizer to obtain material 3, mix material 3 with granulating agent, granulate together with granule 1 obtained in S2, polish, and sieve to obtain the rich Organic Selenium Fertilizer for Selenium Rice Rice.

Embodiment 2

[0031] An organic selenium fertilizer for selenium-enriched rice paddy is prepared by the following steps:

Abstract

The invention discloses an organic selenium fertilizer for selenium-rich rice paddy and a preparation method of the organic selenium fertilizer. The preparation method comprises the following steps: (S1) degreasing and crushing selenium-rich rice bran, adding sodium dihydrogen phosphate for soaking, heating to 20-35 DEG C, and vibrating at a rotation speed, so as to obtain a material 1; (S2) adding selenium-rich yeast into the material 1 obtained in the step (S1), heating to 28-32 DEG C, stirring, mixing, cooling, adding humate and linoleic acid so as to obtain a material 2, adding a granulation agent into the material 2, crushing, sending the material 2 into a granulator, and granulating, so as to obtain particles 1; and (S3) uniformly mixing a nitrogen fertilizer, a potassium fertilizer, a phosphorus fertilizer, a urease inhibitor and an ammonia stabilizer so as to obtain a material 3, adding the granulation agent into the material 3, and granulating, polishing and sieving the material 3 together with the particles 1 obtained in the step (2), so as to obtain the organic selenium fertilizer for the selenium-rich rice paddy. The selenium-rich rice bran is taken as the raw material and is added with humate to introduce a selenium element into the fertilizer again so as to form a multi-layer granule structure, and the selenium element is slowly released, so that the selenium content in selenium-rich rice is increased, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of organic selenium fertilizer, in particular to an organic selenium fertilizer for selenium-enriched rice and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for humans and animals. It has anti-cancer and anti-cancer effects, scavenging free radicals in the body, and anti-aging effects. Human body's selenium nutrition mainly depends on diet, therefore, rationally increasing the selenium level of agricultural products is the fundamental way for human selenium nutrition and health needs. Rice is the main food crop in my country. The national average selenium content of rice is 0.032mg / kg, and the lowest is only 0.016mg / kg, which is far from meeting the normal needs of the human body. Therefore, it is self-evident and urgent to increase the selenium content of rice. [0003] At present, the selenium fertilizer application method for the production of selenium...
