Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an improvement in a method for artificially cultivating plants.

[Conventional technology]

In order to understand this invention, conventional technology will be explained. Here, we will explain the artificial cultivation of mushrooms as an example of plants.

Mushroom cultivation involves letting the wood rot and growing using the decomposed components as nutrients.
Nameko mushrooms, shiitake mushrooms, maitake mushrooms, mannentake mushrooms, etc. fall under this category, and in this application, these are collectively referred to as wood-decaying fungi.

The process of artificially cultivating mushrooms is, for example, for enoki mushrooms, which are the most commonly cultivated mushrooms. Water is added to sawdust and rice bran, packed in a wide-mouthed cultivation bottle, and then sterilized using high-temperature steam to create a culture medium.
After planting the seed fungus and allowing the mycelia to spread sufficiently in the culture medium,
Germinate fruiting bodies (mushrooms) at approximately 4-6℃ and humidity 7.
The cultivation bottles that have completed the germination process are stored in a cultivation room maintained at a growth condition of about 5 to 85%, and allowed to grow for 8 to 12 days, and the seeds are harvested when the stem length is about 12 to 13 cm. It is common for the products to be shipped separately.

This cultivation process is not limited to enoki mushrooms, but is similar to habo in the cultivation of other mushrooms that use sawdust as a culture medium. Focusing on the suitable growth conditions for each type of fruiting body, the temperature, humidity, oxygen, carbon dioxide concentration, etc. of the cultivation room are adjusted to achieve the optimal growth conditions for each type of fruiting body, and the culture medium in a germinated state is placed in the cultivation room. Currently, they are grown in storage, and attempts are being made to improve this. For example, JP-A-59-13 made by these inventors
This method takes advantage of the fact that the optimal growth conditions for the fruiting body disclosed in No. 2825 are different from the growth metabolic conditions of the hyphae that support the growth of the fruiting body.

As a conventional example, the content described in the above-mentioned Japanese Patent Laid-Open No. 132825/1983 will be described. As shown in the examples, the gist of the above publication is that the culture medium side is heated in order to lower the temperature of the fruiting body side to be lower than the temperature of the culture medium side.

FIG. 2 is a sectional view showing the conventional cultivation device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 59-132825, and in the figure, (
1) is a cultivation bottle that has finished sprouting, (2) is a partition that separates the culture medium and fruiting bodies, (3) is a box-shaped cultivation room, (4) is the front door, (5) is fruiting bodies, (a is culture medium, (7a) (8
a) is a ventilation pipe, (7b) and (8b) are exhaust pipes.

Next, the operation will be explained. In the general cultivation method, the cultivation bottle after sprouting is grown in a temperature environment suitable for growing fruiting bodies, but in JP-A-59-132825, the temperature on the fruiting body side is set to a temperature suitable for growing, and the culture medium is This device has been developed to take advantage of the fact that by increasing the side temperature, a higher yield and higher quality can be obtained.This will be explained below. After sprouting, the cultivation bottle (1) is placed in a box-shaped cultivation chamber (3), a partition wall (2) is provided to separate the fruiting body (5) and the culture medium (6), and ventilation pipes (7a) and (8a) are placed. A growth environment is provided by flowing gas at an appropriate temperature to the fruiting bodies and the culture medium, respectively. That is, the ventilation pipe (7a
), and by flowing gas at 26°C from the vent pipe (8a), an environment suitable for Example 1 in the above reference example 2 can be obtained.

[Problem that the invention seeks to solve]

Conventional cultivation equipment is configured as described above, so
Since the temperature is controlled on both the fruiting body side and the culture medium side, the equipment costs are high, and there are many problems such as the cost of operating the equipment.

This invention was made to solve the above-mentioned problems, and while achieving the same effect with conventional equipment,
The purpose is to reduce equipment operating costs without increasing equipment costs.

[Means for solving problems]

The cultivation method according to the present invention utilizes the self-heating of the culture medium and changes the temperature on the culture medium side and the fruiting body side, thereby increasing the yield and improving the quality.

[For production]

In the cultivation method of the present invention, by covering the culture medium with a heat insulating material, the temperature on the culture medium side increases, creating an environment suitable for growth.

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to the drawings. In Figure 1, (1) shows the culture bottle (2), which has finished sprouting, is a partition that separates the culture medium from the fruiting body, (3) shows the temperature on the side of the culture medium, which has a box-shaped insulating material to prevent the temperature of the culture medium from escaping. (
41 is the front door, (5) is the fruiting body, (6) is the culture medium, (
9) is a hole for temperature adjustment.

Next, the operation will be explained. Regarding the basics of cultivation, conventional methods are used, but the gist of this invention is to improve quality and increase yield by creating a temperature difference between the fruiting body and the culture medium.
Since the purpose is to reduce costs, this point will be explained in detail.

In this embodiment, mushrooms, especially those using wood-decaying fungi, undergo fermentation during the culturing period, resulting in heat generation. This invention makes effective use of this heat generation.

The culture medium (6) inside the cultivation bottle (1) ferments during the cultivation period and the temperature rises.In order to effectively utilize this heat, the cultivation bottle (1) is surrounded by a partition wall (2) and a front door (4). The culture medium is cultured in a culture medium storage room (3). With this configuration, the heat generated in the culture medium (6) can be used effectively and energy saving can be achieved.

JP-A-59-132825 is the same in that the culture medium side is heated, but differs greatly in that the heat generated on the culture medium side becomes waste heat and that environmental control equipment on the culture medium side is required. If temperature control is required, a hole (9) for temperature adjustment may be provided and the size of the hole may be adjusted.

In addition, in the above embodiment, the culture medium incubation chamber (3) surrounded by the partition wall (2) and the front surface #(4) does not require each member as long as it constitutes an incubation chamber. That is, for example, if the front door (4) is not required, the present invention can be implemented even if the front door (4) is included in the culture medium storage chamber (3). In addition, the culture medium storage chamber (3)
Although any material used can provide insulation, the effectiveness can be enhanced by using materials with excellent insulation properties.

Incidentally, although the above embodiments have been explained using mushroom wood-decaying fungi, it is clear that the present invention can be practiced in cases where the culture medium has the property of generating heat or endotherm during the growth of plants.

〔Effect of the invention〕

As described above, according to the present invention, (6) since the heat generation of the culture medium is used, by creating a temperature difference between the fruiting body and the culture medium, quality is improved and yield is increased, and the equipment is not required. This has the effect of eliminating unnecessary running costs.
