Lentinus edodes cultivation technology

Abstract

The invention discloses a Lentinus edodes cultivation technology. The Lentinus edodes cultivation technology comprises the steps of batching, sub-bagging, sterilization, inoculation, spawn running andfruiting, and further comprises a pre-wetting step between the batching step and the sub-packaging step; and the pre-wetting step is characterized in that a prepared dry culturing material containingold wood chips is pre-wetted before being bagged, and is stirred during watering, the pre-wetting temperature is controlled at 18-20 DEG C, the pre-wetting period is 2-4 days, and the water content of the obtained pre-wetted mixed culturing material is (60 + / - 3)% to make the culturing material absorb sufficient water and be sufficiently wetted. The pre-wetting step arranged before the sub-bagging and the control of the pre-wetting temperature at 18-20 DEG C promote the germination and growth of competitors, and the poor resistance of the competitors to high temperature and high humidity in the competitor growth and breeding stages is used to increase the sterilization efficiency.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a technology for cultivating shiitake mushrooms. Background technique [0002] Sawdust, the main raw material for early edible fungus cultivation, was gradually replaced by corncobs and cottonseed husks as the use of natural forest protection decreased. However, wood chips must be used for the cultivation of wood rot fungi such as shiitake mushrooms and fungus. The main components of wood chips are crude fiber and carbohydrates, which are the substances that provide carbon sources in the formula. As the source of fresh sawdust has decreased sharply, people have begun to use abandoned and air-dried wood chips in the past or wood crushed wood chips that have been dried for many years in forest farms (that is, old wood chips) to cultivate shiitake mushrooms. In fact, the sawdust does not absorb enough water and has a dry core, which is a poor conductor of heat, and it is d...

Problems solved by technology

As the source of fresh sawdust has decreased sharply, people have begun to use abandoned and air-dried wood chips in the past or wood crushed wood chips that have been dried for many years in forest farms (that is, old wood chips) to cultivate shiitake mushrooms. In fact, sawdust does not absorb enough water, and has dry core, which is a poor conductor of heat, and it is difficult to sterilize thoroughly, which will cause a lot of pollution and bring serious economic losses to mushroom farmers.
