Artificial fruiting method for black fungus

Abstract

The invention discloses an artificial fruiting method for black fungus. The method comprises the following steps: (1) preparation of pure virus-free strains of wild black fungus; (2) preparation of pure wheat-grain strains; (3) collection and air drying of tree branches with diameters of equal to or less than 50 mm; (4) bundling and soaking treatments, water control and moisture regulation, and drilling and inoculation: a step of bundling the air-dried tree branches and then carrying out soaking into limewater for 18 to 24 h, and taking the soaked tree branches out of the limewater; draining water on the surfaces of the soaked tree branches; and then selecting the tree branches with diameters of equal to or more than 30 mm and drilling holes used for inocubation, stuffing the pure wheat-grain strains into the holes, and sealing the hole with wood strips, so inocubation is completed; (5) spore germinaton under a sunshelter; and (6) underground shading and fruiting. The artificial fruiting method for the black fungus provided by the invention ensures quality of the black fungus, saves resources and reduces production cost.

Description

technical field [0001] The invention relates to the field of ecological agriculture, in particular to an artificial ear removal method for black fungus. Background technique [0002] Black fungus is rich in nutrients, especially rich in plant collagen and polysaccharides. Eating black fungus is very beneficial to patients with stones and cancer. At present, the widely used ear extraction technology in black fungus production is plastic bag fungus packaging. Ear technology: Use leftovers of agricultural and forestry by-products such as wood processing sawdust and cottonseed husks as a culture medium to make plastic bag fungus bags, and spray water in the outdoor field to produce ears. Since the sources of agricultural and forestry by-products such as wood processing sawdust and cottonseed hulls are not clear, and their composition varies widely, harmful substances such as pesticide residues and heavy metals in the raw materials cannot be monitored, and they are directly used ...

AI Technical Summary

Problems solved by technology

This method of ear extraction simulates the wild environment and growth conditions, and can produce high-quality black fungus, but this method has a great demand for forest resources, and it is difficult to adopt it in other areas except the fast-growing forest areas in the south. However, even in the south In fast-growing forest areas, wood with a diameter ≥ 100mm is used for earing of black fungus. The cost of earing is close to or higher than the value of black fungus, and the gain outweighs the gain, so it cannot be widely promoted.

Branches are rich in resources and low in cost. They can be used to produce black fungus to reduce costs. However, there are very few branches with a diameter of more than 100mm, and it is difficult to mass-produce black fungus. Branches with a diameter that are too small have poor moisturizing effect, and the survival rate of black fungus is produced very low
