Method for cultivating pleurotus citrinopileatus by using persimmon sawdust

Abstract

The invention relates to a method for cultivating and culturing pleurotus citrinopileatus by using forestry waste persimmon sawdust as main material. The method comprises a breeding process of pleurotus citrinopileatus capable of decomposing the persimmon sawdust and belongs to the technical field of utilization of forestry residues and cultivation of edible and medicinal funguses. The method comprises the following steps of: A, screening a pleurotus citrinopileatus strain having the decomposition advantage to the persimmon sawdust; B, propagating the strain; and C, cultivating the pleurotus citrinopileatus strain. According to the method, in ultraviolet mutation breeding and primary screening steps of the pleurotus citrinopileatus, persimmon sawdust powder is used as an only carbon source to induce and screen the strain which can effectively utilize the persimmon sawdust, so that the breeding efficiency of decomposition strain is improved; and during preparation of liquid strains, the persimmon sawdust is used as a specific substrate corresponding enzymes are generated because of induction function, adaptation time of the strain on a culture medium which uses the persimmon sawdust as the main material is shortened, and the fungus generation speed is improved, so that a technical scheme that the forestry waste persimmon sawdust is effectively utilized by breeding the pleurotus citrinopileatus strain which can efficiently use the persimmon sawdust is provided.

Description

technical field [0001] The invention relates to a method for cultivating and cultivating Pleurotus auricosa using forestry waste persimmon sawdust as the main material, including the process of breeding Pleurotus auricium strains suitable for decomposing persimmon sawdust, which belongs to the cultivation technology of agricultural and forestry residue utilization and edible and medicinal fungi field. Background technique [0002] There are more than 200 varieties of persimmon trees, which are widely distributed in China and are planted in both north and south. Persimmon has high nutritional value and is a popular fruit. It is often made into dried fruit and exported to Southeast Asia. Therefore, as a high economic additional fruit tree, persimmon plays an important role in the adjustment of agricultural economic structure in some areas. Because persimmon trees have a large amount of flowers and fruits and consume a lot of nutrients, they are prone to the phenomenon of "big...

AI Technical Summary

Problems solved by technology

In rural areas where the awareness of circular economy is weak, pruned persimmon branches are often stacked or burned randomly, causing serious waste of resources and environmental pollution. Persimmon leaves also have the problem of waste of resources such as random stacking and simple incineration.
