How to choose suitable fungus strains for ground cultivation and black fungus strains

The advantage is that the cost is very low, the management is extensive and the investment is small, and the disadvantage is that the unit output is low and unstable, and it is easy to be affected by weather factors.

Fungus cultivation method:

Step 1: Seed production, the strains include sawdust strains and branch strains, the former is made of sawdust and Shouwei wheat bran.

Step 2: Vaccination. When the temperature of the material in the bag drops below 30 in Maqinshan, it can be inoculated, and the inoculation should be aseptically operated.

Step 3: Colonization management. First of all, the fungus should be piled up, and the ear wood should be stacked in the shape of "well" or "mountain". The temperature in the reactor should be 20 28 to 28, and the relative humidity should be kept at about 80%.

Step 4: Germ management.

In the large-scale black fungus cultivation base, a culture room will be built to cultivate strains, the size can be determined according to the cultivation scale, generally in 30 50 square meters, the indoor temperature and moisture respect equipment should be adjusted, and the roof of the shed should be installed with a non-powered ventilation fan to ensure that the indoor air is fresh. According to the area of the culture room, several culture racks used to make strains should be welded, the width of the rack is 40 45 cm, the length is not particularly limited, 4 6 layers of sensitivity, and the distance between each layer of the defeated ant branch is about 50 cm.

The cropping takes place between mid-September and early October, and the harvest will be ready until the end of April. Choose varieties that are only medium and large, with black fingers or mountain brightness on the ventral surface, crisp and not hard taste, and are suitable for bag cultivation. Choose the appropriate formula according to the climate and environment.

The planting technology of fungus strains is very simple, so ask the agricultural technician.

1. Pay attention to the appearance. Check that the bottle label is consistent with the black fungus species to prevent mispurchase. The incubation time should be within two months. The age of the bacteria should be 30-40 days from the date of vaccination. At the same time, check whether the wall of the bottle is cracked or the tampon is off.

2. Pay attention to the mycelium. The white mycelium is of high purity, and the villi are thick, short, and dense, making it a high-quality strain. If there are green, yellow, red, green, and gray mycelium, they are strains that are infected with other bacteria and need to be removed.

3. Pay attention to the ear base. If there are no light black ear sockets between the bottle wall and the material, this is a good strain, and a small amount of ear sockets is a normal strain. If there are too many ear roots, then the number of offspring will be too many. Although the heading is early and abundant, the growth is small and the yield is low.

4. Pay attention to the sediment. No or only light brown colloids on the bottle wall are qualified; If there is a yellow-brown liquid, it is an aging bacterium and cannot be purchased.

5. Pay attention to the fungus blocks. Sawdust bacteria have mycelium on the surface, and the sawdust is no longer visible. It is better to dig it into pieces and not loosen it. If the fungus has dried up, it is not available.

6. Pay attention to the smell. Pull off the tampon, smell the fragrance of the fungus, qualified; If it gives off sour liquor, mold, and other odors, it is a spoiled bacterium and is not available.

7. Pay attention to clever use. If the strain is incubated for too short a time or at too low a temperature, the mycelium is not full or cannot grow into sawdust, it should be continued at a suitable temperature before being used for inoculation. If inoculation of the appropriate age strain cannot be achieved for a period of time after purchase, it should be stored in a clean, dry, and dark room.

Before inoculation, it is strictly forbidden to pull out the tampon, and the bacteria that have been inoculated in the open bottle should not be left overnight to prevent contamination by miscellaneous bacteria.

The above is today's sharing, I hope it can help you.

Areas with a large temperature difference between day and night are suitable for growing fungus.

China is the main producer of fungus, mainly distributed in Jilin, Heilongjiang, Liaoning, Inner Mongolia, Guangxi, Yunnan, Guizhou, Sichuan, Hubei, Shaanxi and Zhejiang, among which Hailin City, Dongning County, Mudanjiang District, Heilongjiang Province and Huangsongdian Town, Jiaohe County, Jilin Province are the largest black fungus bases in China.

The size of the fungus can be both wild and artificially cultivated, and the seed body is ear-shaped, leaf-shaped or cup-shaped, thin, with wavy edges, 3-10 cm wide, about 2 mm thick, and is fixed on the substrate with a short stalk or a narrow attachment part on the side. The color is dark and brown, the texture is soft and gelatinous, thin and elastic, translucent when wet, and shrinks into a brittle and hard keratin similar to leather. The taste is delicious in imitation of the trapped hall, and it can be vegetarian and meaty, camp.

Hello, I am very happy to answer to your question Since the establishment of the all-light intermittent fog cultivation model, the cultivation of black fungus substitute materials has been expanding, forming an industrial development situation of the southern expansion of the northern ear, and new varieties and technologies have also been emerging [1, 3]. Among them, the strains have developed from the original sawdust strains to the coexistence of sawdust strains, branch strains, and liquid strains, but the liquid strains have not been widely used due to their large investment and complex technology [4]. Compared with sawdust strains, shoot strains are gradually being popularized and applied in Northeast China because of their advantages of convenient inoculation, short germination time and high production efficiency.

However, there are also problems such as high contamination rate and difficulty in germination in production. Based on years of scientific research, production experience and research, the author writes this article for the reference of industry insiders. 1. Common problems in the production of shoot strains (1) Insufficient soaking time.

If it is not fully soaked, it will affect the growth of the strain, and the amount of strain will be small. (2) Insufficient ripening time. Only the surface of the shoot has hyphae, and there is little or no inner hyphae.

3) Insufficient vaccination. The gap between the branch species and the cultivation material is formed, which is not conducive to the germination. 2. Production of branch strains Branch strains refer to the use of broad-leaved branches suitable for the cultivation of black fungus (or with convenient wooden chopsticks, sorbet sticks, the same below) as the main substrate for the production of strains, commonly known as chopsticks strains.

Its process flow: shoot preparation) soaking) ingredients) bagging) sterilization) cooling) inoculation) culture) ripening) quality inspection) cultivation bag inoculation) germination) out of the ear. (1) Preparation of shoots.

Birch, oak and other broad-leaved branches suitable for black fungus cultivation are selected, and the diameter is required to be 315 715 mm and the length is 15 18 mm. (2) Soaking of shoots. Soak in clean water for more than 12 hours and press with a weight to prevent the shoots from coming to the surface.

Until the shoots are completely soaked and there are no white hearts, drain and set aside. If the soak is not thorough, it is easy to have problems such as incomplete sterilization, slow eating and contamination. (3) Ingredients.

The culture material of shoot strains is generally the same as that commonly used for wood chip straines. Formula: 90% of the main substrate branches, 718% of the excipients sawdust, 2% of wheat bran, 011% of glucose (or sugar), 011% of gypsum powder, pH 610 615.

4) Bagging First, fill 015 110 cm of excipients into a 15 17 @28 33 ( cm) high-temperature resistant polypropylene plastic bag, insert the branches, then fill the gaps with ingredients, and finally spread 015 110 cm thick ingredients on the upper layer, seal and wait for sterilization. (5) Bag sterilization.

Autoclaving, generally 0112 0115 MPa pressure for 2 4 hours. Natural depressurization cooling.

"Ground black fungus", also known as "plastic bag ground black fungus", is a kind of black wood and ear substitute materials, gardening cultivation technology. The technology uses sawdust and straw as raw materials, and uses plastic bags to hold kilograms of dry material in each bag, which is sterilized, inoculated and raised, and placed in the field and under the fruit scattered and sensitive garden.

Process flow: preparation of original seed medium - bottling - sterilization - inoculation (mother species) - culture - original seed - preparation of culture bag medium - bagging - sterilization - inoculation (original seed) - culture scratch - ear management.

1. Seed production: The strains include sawdust strains and branch strains.

2. Preparation of ear wood: After the cultivation site is selected, the ear wood should be prepared, and the commonly used ear wood species are the tree species of the complete bucket family and birch.

3. Inoculation: The tools used for inoculation should be sterilized with ethanol in advance.

4. Planting management: First of all, the fungus should be piled up, and the ear wood should be stacked in the shape of "well" or "mountain".

5. Scattered pomp: generally use tiled pomp.

Hello, I am happy to serve you and give you the following answers: the yield of fungus species refers to the yield of fungus strains, which refers to the yield of fungus strains, that is, the yield of fungus strains per kilogram of fungus. There are many factors influencing the yield of fungus species, the main ones are as follows:
