Abstract

PROBLEM TO BE SOLVED: To provide a method for continuously generating mushrooms having good quality even under an environment of low temperature or high temperature. SOLUTION: In the process for generating mushrooms in the mushroom bed culture of SIITAKE (Lentinus edodes), the germination process after the second turn is carried out as follows: the temperature of the water which is used for immersing mushroom beds or for spraying it on mushroom beds is controlled at 16-23 deg.C, or/and the mushroom beds are managed for 0.5-3 days under an environment kept at almost saturated humidity and a temperature of 13-22 deg.C after immersing in water or the spraying of water. Thus, the germination of mushrooms is accelerated and mushrooms are continuously generated. Further, during the above-mentioned management of 0.5-3 days, a mild ventilation is carried out continuously or with an interval of at least one time every a half day in such a degree that the temperature does not get out of the maintenance temperature range.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a shiitake mushroom bed which continuously produces excellent quality mushrooms without significantly reducing the number of mushrooms produced in a step of cultivating a shiitake mushroom bed.

[0002]

2. Description of the Related Art The germination method for the purpose of generating a second or subsequent Shiitake mushroom bed, which has been a conventional method, mainly employs the following method. This method is called a "water immersion method", in which a bacterial bed is immersed in water for a certain period of time after the previous outbreak is completed, and the next mushroom is waited for. In this case, the temperature of the water used for flooding is 15 in winter in proportion to the temperature.
In summer, the temperature is 20 ° C. or higher, but at a low temperature of 20 ° C. or lower, a relatively large number of mushrooms are generated in the early stage of the active period.

However, in this flooding method, when a medium-temperature variety is used, the temperature at which it is generated is suitable for growing mushrooms.
When the temperature is about 0 to 15 ° C., the number of buds sharply decreases, and the development period tends to extend over a long period of time. In particular, the temperature often drops to 10 ° C. or less in the low temperature season in winter. Similarly, when the temperature is lowered to 15 ° C. or lower, there is a problem that mushrooms hardly occur.

In order to continuously generate mushrooms, a method of using a heater to maintain the temperature at 15 to 20 ° C. and a somewhat higher temperature as an environment for generating the mushrooms is generally used. However, there are problems such as difficulty in environmental management and high cost due to easy drying due to heating.

[0005] In the high temperature season in summer, even when a high temperature variety is used, the temperature is as high as 25 ° C or more, and when the flooding temperature is as high as the temperature, germination after the flooding operation is not normal, and mushrooms are not obtained. There are problems such as a decrease in shape quality and a stop of generation.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems, and provides a method for continuously producing excellent quality mushrooms even in a low-temperature or high-temperature environment. .

[0007]

In order to achieve the above-mentioned object, the present invention provides a method for controlling the temperature of water for immersing a bed of shiitake mushrooms to 16 to 2 hours.
3 ° C. Alternatively, at a stage before entering the generation step after flooding, the bacterial bed is kept at a temperature of 13 to 22 ° C. for 0.5 to 3 days in a humidity environment close to saturation. Alternatively, it is a method of generating a mushroom bed of mushrooms, characterized in that the mushroom bud cutting is promoted and the mushroom is continuously generated by using those temperature holding steps in combination.

[0008] In the above configuration, during the period of 0.5 to 3 days of management, continuous or at least 0.5
It is a method of generating a shiitake mushroom bed that ensures respiration of the bacterial bed and promotes the growth of mushrooms of excellent quality by performing gentle ventilation so that the temperature does not deviate from the holding temperature once a day. .

[0009] The Shiitake mushroom bed, which promotes germination by the method described above, can continuously produce excellent quality mushrooms even in a low or high temperature environment.
