Embodiment 1

[0031] A method for preparing an organic selenium nutrient solution for crops, using Bacillus subtilis to ferment selenium-enriched yeast to obtain a selenium-enriched hydrolyzate, the fermentation process comprising the following steps:

[0032] Step 1. Stir 3 parts by weight of molasses, 3 parts by weight of soybean meal and 5 parts by weight of tapioca starch at 110°C for 35 minutes to sterilize. Stirring for 1 h at a rotating speed of 1 h to obtain the second fermentation substrate;

[0033] Step 2: Spray a small amount of deionized water into the second fermentation substrate until the water content of the second fermentation substrate is 20%, add 1 part by weight of Bacillus subtilis, and stir for 1 hour at a speed of 100 r / min. Continue to spray deionized water into the second fermentation substrate to make its water content reach 50%, and then place the second fermentation substrate at a temperature of 35°C and a humidity of 85% to ferment for 56h, and ferment During ...

Embodiment 2

[0045] A method for preparing an organic selenium nutrient solution for crops, using Bacillus subtilis to ferment selenium-enriched yeast to obtain a selenium-enriched hydrolyzate, the fermentation process comprising the following steps:

Abstract

The invention discloses a preparation method of an organic-Se nutrient solution for crops. According to the method, bacillus subtilis is adopted to perform fermentation treatment on Se-enriched yeast, the Se-enriched yeast is hydrolyzed by the aid of protease produced in the metabolic process of the bacillus subtilis, a Se-enriched hydrolysate is obtained, and the organic-Se nutrient solution for the crops is prepared. The invention further discloses the organic-Se nutrient solution applied to the crops and produced with the preparation method of the organic-Se nutrient solution for the crops as well as an application of the organic-Se nutrient solution for the crops. With the adoption of the preparation method, all raw materials are sufficiently and reasonably utilized, complete and sufficient utilization of the raw materials is realized, no residues and residual liquids are produced, and environmental pollution is avoided; the content of organic-Se in the prepared organic-Se nutrient solution for the crops is high, the organic-Se exists in modes of Se substituted amino acid and short peptide, plant absorption is facilitated, and the content of the organic-Se in agricultural products can be remarkably increased.

Description

technical field [0001] The invention relates to the field of organic selenium fertilizer. More specifically, the present invention relates to a crop organic selenium nutrient solution and its preparation method and application. Background technique [0002] In my country, more than 60% of the land lacks selenium, so the selenium content of agricultural products is generally insufficient. According to the "Reference Intake of Dietary Nutrients for Chinese Residents" formulated by my country in 2000, the daily intake of selenium for adults over the age of 18 should be more than 50 micrograms (50 μg / d), which is the daily average intake recommended by the World Health Organization (WHO). The amount is 50-200 μg / d, but the actual average intake of Chinese residents is only 27 μg. Some areas of our country are extremely deficient in selenium, and the situation is even more serious. Selenium plays an important role in preventing cancer, anti-oxidation and improving immunity in t...
