Problems solved by technology

[0012] The purpose of the present invention is to overcome the loss of inorganic nitrogen, phosphorus, and potassium salts, and at the same time solve the problem of burning blueberry roots when cow dung and sawdust are used directly, and can rot the weed seeds in cow dung to the greatest extent. The present invention provides a Reasonable process, simple operation, short process cycle, high degree of comprehensive utilization of rural waste such as cow dung, rapid fermentation of cow dung, rapeseed dry cake and sawdust to prepare blueberry selenium-rich organic fertilizer production process, make full use of microorganisms in the fermentation process The advantage of converting inorganic nitrogen, phosphorus, and potassium salts into organic salts is to increase the content of organic selenium in fertilizers, so as to promote the growth and development of blueberries, increase production, increase income, and improve quality

Embodiment 1

[0039] Screening of Bacillus subtilis Lys-979: The high-temperature-resistant Bacillus Lys-979 was isolated from corn stalks, rice straw, and tobacco piles in Yunyuan, Hunan Agricultural University. After morphological identification and molecular identification of 16SRNA evolution tree, the strain Lys- 979 is Bacillus subtilis. Bacillus subtilis Lys-979 was deposited in the General Microorganism Center of China Committee for the Collection of Microorganisms on September 8, 2015, and the preservation number is CGMCCNo.11333. Bacillus subtilis Lys-979 slant medium formula: yeast extract 0.5%, glucose 2.0%, agar powder 0.7%, pH 7.0, water 250mL, sterilized at 121°C for 25 minutes; cultured at 40°C for 12-18 hours; Bacteria liquid medium formula and fermentation conditions: inoculate one loop of strain Lys-979 test tube slant into four 500mL Erlenmeyer flasks, the medium formula is yeast extract 0.5%, glucose 2.0%, pH7.0, water 250mL, 121°C Sterilize for 25 minutes; ferment at 4...

Embodiment 2

[0041] 600kg of cow dung and 200kg of sawdust are mixed, and the water content of the mixture is controlled at 30% to 50%. Inoculate 60L of Bacillus subtilis Lys-979 fermentation broth, mix well and cover with film to keep warm. The temperature of the mixture is controlled above 50° C., and the fermentation time is 8 days. Then add 300kg of rape dry cake (that is, the residual waste residue after rapeseed is pressed through high temperature) and mix, and then add the final concentration of 1.5% urea, 1.5% potassium sulfate, 0.5% disodium hydrogen phosphate, and 0.015% selenous acid to the mixture. sodium, stir well. Then inoculate 60 kg of Saccharomyces cerevisiae powder, and after stirring evenly, the water content of the mixture is controlled at 30% to 50%, the temperature is controlled at 20° C. to 30° C., and the stirring and fermentation time is 5 days. After the fermentation of Saccharomyces cerevisiae is completed, the fertilizer with yeast smell is directly applied t...

Embodiment 3

[0047] 1200kg of cow dung and 500kg of sawdust are mixed, and the water content of the mixture is controlled at 30% to 50%. Inoculate 150L of Bacillus subtilis Lys-979 fermentation broth, mix well and cover with film to keep warm. The temperature of the mixture is controlled above 50° C., and the fermentation time is 7 days. Then add 700 kg of dried rapeseed cake and mix to obtain a mixture, then add 2.5% urea, 1.5% potassium sulfate, 1.5% disodium hydrogen phosphate, and 0.025% sodium selenite to the mixture respectively, and stir evenly. Then inoculate 200 kg of Saccharomyces cerevisiae powder, and after stirring evenly, the water content of the mixture is controlled at 30% to 50%, the temperature is controlled at 20° C. to 30° C., and the stirring and fermentation time is 6 days. After the fermentation of Saccharomyces cerevisiae, the fertilizer with yeast smell is directly applied to the field, or it can be granulated into granular fertilizer by adding water for potting. ...

Abstract

The invention discloses biological organic fertilizer suitable for blueberry plantation. 40-80 parts of cow dung and 10-30 parts of sawdust are mixed and then are fermented by bacillus subtilis at a high temperature for 3-10 days, 20-50 parts of rape dreg cake is added into the fermentation product, a small amount of urea, potassium sulfate, disodium hydrogen phosphate and sodium selenite are added into the mixture, and the mixture is uniformly stirred and fermented by saccharomyces cerevisiae at a normal temperature for 3-6 days so that a finished product is obtained. Through use of a large amount of weed seeds in high temperature decayed cow dung and high temperature fermentation, burnt blueberry root is effectively prevented and cow dung odor is fast removed. Through secondary fermentation, a urea substance loss is avoided in high temperature fermentation, efficiency of conversion of inorganic nitrogen into organic nitrogen is improved, and fertilizer long residual action is guaranteed. Through use of a large amount of organic matters such as cow dung, sawdust and rape dreg cake containing a large amount of cellulose, a soil structure is improved and blueberry root rapid growth is promoted.

Description

Technical field [0001] The invention relates to a bio-organic fertilizer suitable for planting blueberries, belonging to the technical field of fertilizer processing. Background technique [0002] Selenium is an essential trace element for the human body. Selenium participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. Among them, glutathione peroxidase catalyzes the conversion of hydroperoxide or lipid peroxide into water or various alcohols in vivo, eliminates the attack of free radicals on biofilms, and protects biofilms from oxidative damage; Selenium participates in the formation of iodothyronine deiodinase. There are many selenium-rich foods in the domestic market, but the selenium content of each product is not clearly marked, which has caused great troubles for consumers. How much of these foods do I need to eat to achieve selenium supplementation? Effect. [0003] Selenium can improve human immunity, promote the...
