Embodiment 1

[0027] Weigh 100kg of waste Cordyceps culture medium and put it into a reaction tank, then add 50L (specific gravity 1.1) of guronic acid mother liquor, and let stand at room temperature (10-30°C) for 2 hours. Thereafter, fully stir with a stirrer until the blocky waste medium is dispersed wheat grains and Cordyceps hyphae.

[0028] Use a strainer to fish out the wheat grains and Cordyceps mycelia (about 115kg) in the soaked waste Cordyceps culture medium, filter off the excess guronic acid mother liquor (about 5L), adjust the pH to 6.0 with slaked lime (about 2.4kg), and press The standard organic fertilizer is supplemented with appropriate amount of NPK and trace elements, and dried at 60°C with a dryer to obtain organic fertilizer (about 50kg). Among them, the amount of NPK added (N+P 2 o 5 +KCl) is 5.7%; the amount of trace elements added is 2.9%

[0029] In the organic fertilizer, by weight percentage, the water content of the organic fertilizer is 15%; the organic mat...

Embodiment 2

[0035] Weigh 100kg of the waste Cordyceps culture medium and put it into the reaction tank, then add 50L (specific gravity: 1.2) guronic acid mother liquor, and let stand at room temperature (10-30°C) for 6 hours. Thereafter, fully stir with a stirrer until the blocky waste medium is dispersed wheat grains and Cordyceps hyphae.

[0036] Use a strainer to fish out the wheat grains and Cordyceps mycelia (about 120kg) in the soaked waste Cordyceps culture medium, filter off the excess gulonic acid mother liquor (about 9L), adjust the pH to 6.5 with slaked lime (about 3.0kg), and press The standard organic fertilizer is supplemented with an appropriate amount of NPK and trace elements, and air-dried for 15 days under natural conditions to obtain an organic fertilizer (about 54kg). Among them, the amount of NPK added (N+P 2 o 5 +KCl) is 5.3%; the amount of trace elements added is 3.5%

Embodiment 3

[0041] Weigh 100kg of waste Cordyceps culture medium and put it into a reaction tank, then add 50L of guronic acid mother liquor (specific gravity 1.05), and let it stand at room temperature (10-30°C) for 4 hours. Thereafter, fully stir with a stirrer until the blocky waste medium is dispersed wheat grains and Cordyceps hyphae.

[0042] Use a strainer to fish out the wheat grains and Cordyceps mycelia (about 118kg) in the discarded Cordyceps militaris culture medium after soaking, filter off the excess guronic acid mother liquor (about 7L), adjust the pH to 7.0 with slaked lime (about 3.5kg), and then Add appropriate amount of NPK and trace elements according to organic fertilizer standards, and dry at 60°C with a dryer to obtain organic fertilizer (about 53kg). Among them, the amount of NPK added (N+P 2 o 5 +KCl) is 4.9%; the amount of trace elements added is 5.5%

Abstract

The invention belongs to the technical field of resource utilization of industrial and agricultural production waste, and specifically relates to an organic fertilizer produced from waste culture medium of Cordyceps militaris and vitamin C fermentation waste guaronic acid mother liquor and a preparation method thereof. Soak the waste medium of Cordyceps militaris in the mother liquor of gulong acid with a specific gravity of 1.000-1.300 for 20min-6 hours, adjust the pH to 6.0-7.0, and add appropriate amount of N, P, K and trace elements, after drying or air-drying That is, it becomes an organic fertilizer; wherein, the weight ratio between the waste medium of Cordyceps militaris and the mother liquor of gulong acid is 1:0.05‑1. The invention utilizes waste medium of Cordyceps militaris and vitamin C fermentation industrial waste as resources to produce high-quality organic fertilizer, which not only solves the environmental pollution problem of industrial and agricultural production waste, but also provides high-quality organic fertilizer for agricultural production.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of industrial and agricultural production waste, and specifically relates to an organic fertilizer produced from waste culture medium of Cordyceps militaris and vitamin C fermentation waste gulong acid mother liquor and a preparation method thereof. Background technique [0002] After harvesting Cordyceps militaris, a large amount of waste medium will be produced. At present, these remaining media are discarded and piled up around the planting shed. These waste culture mediums are often polluted by mold within 2-3 days, causing harmful molds to proliferate in large numbers, which not only affects the environment, but also causes contamination by miscellaneous bacteria in the production of Cordyceps militaris, reducing the production of Cordyceps militaris. [0003] In fact, the nutrients in the medium of Cordyceps militaris are very rich. The medium contains a large amount of Cordyc...
