Embodiment 1
[0039] In the embodiment of the present invention, according to the production process of raw materials in parts by weight: 6% soybean meal powder (60 mesh) is added with 2% molasses, 0.3% KH 2 PO 4 , 91.7% potato juice, prepared as a seed medium, inoculated with 5% of the activated Bacillus endophyticus citrus YS-45 suspension, 160rpm, 37°C, cultured for 24h, and the seed fungus was formed. Then press 6% soybean meal powder (60 mesh), 2% molasses, 0.3% KH 2 PO 4 , 91.7% water ratio, mix evenly, insert the above-mentioned seed bacteria, 250rpm, 37°C, fermentation time 72h, filter the fermentation liquid with industrial filter cloth, and obtain soybean meal amino acid solution. Then, according to the mixing ratio of molasses, soybean meal amino acid, urea and sodium selenite in the ratio of 1:10:7.5:0.07, 160 rpm, 37° C., shaking for 48 hours, the organic selenium crop nutrient was obtained. When used on rice, dilute 25 times, and spray 3 times on the foliage of rice at the ...

Abstract
The invention discloses an organic selenium crop nutrient and a preparation method for the same. The organic selenium crop nutrient comprises the following raw materials in parts by weight: 0.5-1.5 parts of molasses, 5-15 parts of soybean meal amino acid, 6-9 parts of urea, and 0.04-0.1 part of sodium selenite. The preparation method for the organic selenium crop nutrient comprises the following steps of: oscillating all raw materials for 24-72 hours in the conditions of a rotation speed of 120-200 rpm and a temperature of 35-40 DEG C, and sieving to obtain a filtrate, namely, the organic selenium crop nutrient. The content of organic selenium in the organic selenium crop nutrient disclosed by the invention is greater than 0.3 g/L. Additionally, according to the organic selenium crop nutrient and the preparation method disclosed by the invention, harm brought by the too high dosage of an inorganic selenium fertilizer to a human body, and fertilizer damage phenomena of seedling burning, leaf spots and the like due to the inappropriate dosage of the inorganic selenium fertilizer are overcome.
Description
technical field [0001] The invention relates to a crop nutrient, in particular to a plant nutrient containing organic selenium, including a selenomethionine added plant nutrient and an organic selenium plant nutrient produced by fermentation. Background technique [0002] Due to the input and use of a large amount of chemical fertilizers, some physical and chemical properties of the land have changed, which has brought many negative effects on agriculture. Therefore, many scholars have begun to study bio-organic fertilizers to achieve high yields and virtuous cycle utilization of land. Among them, foliar organic fertilizers are At present, there are more than 2,000 organic water-soluble foliar fertilizers such as humic acid, amino acid, and alginic acid. In my country, most people are seriously deficient in the trace element selenium. Nutritionists point out that more than half of the regions in our country are deficient in selenium. In order to supplement selenium, crops a...
