Problems solved by technology

In the prior art, the rate of white fungus ear production is low, and the size of the cultivated white fungus is not uniform, and the section wood is easily infected with nematodes and other pests, causing the ear base to rot easily. In the prior art, in order to prevent and control such pests, trichlor is often used. Insects, etc. spray earwood, which can easily cause chemical residues and form a health hazard; on the other hand, segmented wood is easily infected with germs, such as cotton rot, schizophyllum, mold, woody fungus, etc., which will make the fruiting body ossified and affect the yield.

Embodiment 1

[0022] 1.1 Select a section of wood with a diameter of 9-10cm, saw it into a short section of 1m, and drill a hole with a drill bit with a diameter of 1.2cm. The depth of the hole is 1.8cm, and the hole spacing is 10cm. After drilling, put it into the treatment agent Soak for 2 hours (the treatment agent should not pass through the wood section during soaking), take it out and dry it for 8 days, add cellulase accounting for 2% of the weight of the treatment agent to the treatment agent, then soak the section wood for a second time for 3 hours, take it out and dry it for 8 days, pre-treated timber;

[0023] The treatment agent adopts the following preparation method: mash 20 parts of alfalfa, 8 parts of purslane, 5 parts of pokeweed and 6 parts of clams, add 200 parts of distilled water, heat up to 40-50 ° C, keep stirring for 2 hours, filter , when the temperature is lowered to 38°C, add 4 parts of sucrose and 2 parts of polyethylene glycol, and stir evenly.

[0024] 1.2 Wide...

Embodiment 2

[0027] 2.1 Select a section of wood with a diameter of 9-10cm, and drill holes with a drill bit with a diameter of 1.5cm. The depth of the holes is 2cm, and the hole spacing is 10cm. The composition and preparation of the treatment agent are the same as in Example 1), take it out and dry it for 7 days, add cellulase accounting for 1% of the weight of the treatment agent to the treatment agent, then soak the section wood for a second time for 3 hours, take it out and dry it in the air 7d, get the pretreated wood;

[0028] 2.2 Widen the pretreated section wood to a diameter of 1.5cm, fill the widened hole with 3cm of base material (composition is the same as in Example 1), let it stand for 20 minutes, inoculate and seal, and move the inoculated section wood into the room For stacking, the temperature of the fungus is 23-25°C, and the humidity is kept at 60%. After the white colonies are lodging, the humidity is adjusted to 75%.

Abstract

The invention belongs to the technical field of edible fungi cultivation, and in particular relates to a cut-log tremella cultivation method. The method is realized through the following steps: selecting a cut-log and punching, soaking the cut-log in a treating agent, air drying, soaking for a second time and air drying, expanding the hole of the pre-treated cut-log, adding a base material, inoculating, spawn running, and then performing common management. Through pre-treating and fermenting the cut-log, the probability that the cut-log infected by germs and pests is greatly reduced, the shape of cultured tremella is good and uniform, and the yield is high; according to the cut-log tremella cultivation method provided by the invention, the cut-log is creatively punched and then soaked and air dried, so that nutrient substances can quickly immerse into the cut-log, and the use ratio is improved.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, in particular to a method for cultivating white fungus. Background technique [0002] Tremella is composed of two parts: mycelium and fruiting body. Mycelium is a slender filamentous body with a diaphragm and branches, which can secrete light yellow water droplets and form fruiting bodies under suitable conditions. The fruiting body is the edible part, which is gelatinous and elastic. Tremella has the effects of nourishing yin and moistening the lungs, benefiting the stomach and promoting body fluid, etc. It is recognized by the Chinese medicine circle as a food with medicinal value and medicinal effect, and is loved by people. Duanmu Tremella is planted on Duanmu with a tree age of about 7 years. The trees suitable for tremella growth are sawn into short sections and used as the substrate for tremella growth. Its nutritional value is greater than that of bagged tremella, and i...
