Problems solved by technology

[0006] The purpose of the present invention is to overcome the loss of inorganic nitrogen, phosphorus, and potassium salts, solve the problems of bletilla striata tuber burnt and rotten roots when directly using cow dung and sawdust, and can rot the weed seeds in cow dung to the greatest extent. The invention provides a production process for preparing Bletilla striata fermented organic fertilizer with reasonable technology, simple operation, short process cycle, high degree of comprehensive utilization of cow dung and sawdust, and rapid fermentation of cow dung and sawdust, which can promote the growth and development of Bletilla striata, increase production and income, and improve quality. new fermented fertilizer

Embodiment 1

[0033] 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

[0035]750kg of cow dung and 250kg of sawdust are mixed, and the water content of the mixture is controlled at 30% to 50%. Inoculate 80L 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. After the fermentation, add 400 kg of dried rapeseed cake and mix to obtain a mixture, then add 2.5% ammonium chloride, 2.5% potassium nitrate, and 1.5% sodium dihydrogen phosphate to the mixture at a final concentration, and stir evenly. Then inoculate 80 kg of Trichosporium cephalospora yeast 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 Trichosporium cephalosporin, the fertilizer with yeast smell is directly applied to the field, or it can be granulated into granular fertilizer by...

Embodiment 3

[0041] 1200kg of cow dung and 400kg of sawdust are mixed, and the water content of the mixture is controlled at 30% to 50%. Inoculate 140L 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. After the fermentation, 800 kg of dried rapeseed cake was added and mixed to obtain a mixture, and then 2.5% ammonium chloride, 2.5% potassium nitrate, and 2% sodium dihydrogen phosphate were added to the mixture at a final concentration, and stirred evenly. Then inoculate 170 kg of Trichosporium cephalospora yeast 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 Trichosporium cephalosporin, the fertilizer with yeast smell is directly applied to the field, or it can be granulated int...

Abstract

The invention discloses a bio-fertilizer applicable to cultivation of bletilla striata. The bio-fertilizer is prepared by mixing cow dung and sawdust, subjecting the obtained mixture to high temperature fermentation by bacillus subtilis for 3 to 10 d, adding a rapeseed cake, ammonium chloride, potassium nitrate and sodium dihydrogen phosphate into a product obtained after fermentation, carrying out uniform mixing under stirring, and carrying out normal temperature stirring fermentation by Trichosporon capitatum for 3 to 6 d. According to the invention, a great amount of oil and starch substances in the rapeseed cake are made to full use to provide a great number of carbon sources for the Trichosporon capitatum, so conversion of inorganic nitrogen in the fertilizer into organic nitrogen is substantially promoted, which is beneficial for improving the quality of bletilla striata; and high temperature is employed for decaying a great number of weed seeds in the cow dung, and high temperature fermentation can effectively prevent the situation of root burning of bletilla striata and benefits rapid deodorization of the cow dung.

Description

Technical field [0001] The invention relates to a bio-organic fertilizer suitable for cultivation of bletilla striata, belonging to the technical field of fertilizer processing. Background technique [0002] Bletilla striata, perennial herb, pseudobulb tuberous, white, thick, with finger-like divergences. The flowers are beautiful and cultivated for ornamental use. The stem is stout, erect, 30-60 cm high. 3-6 leaves, lanceolate or broadly lanceolate, apex acuminate, base sheath-like clasping. Raceme terminal, sparse, with 3-8 flowers, large and beautiful, purple-red. Petals 3, lip obovate-oblong, deeply 3-lobed, middle lobe with wavy teeth on edge, side lobe partially covering stamen. Sepals 3, petallike. Capsule, terete, above, with 6 longitudinal ribs prominent. The seeds are as small as dust. The flowering period is from late April to late May, and the fruit ripening period is mid-to-late November. There is a variety of Bletilla striata with white flowers, and hor...
