Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for cultivating strawberries in a rice husk culture medium using rice husks.

"Prior Art" and "Problem to be Solved by the Invention" In recent years, plant cultivation other than soil cultivation has become widespread, and strawberry cultivation has also been carried out using hydroponics and rock wool cultivation.

However, in this hydroponic cultivation of strawberries, the medium is a solution, and it is necessary to flow and stop the medium solution at regular intervals (for example, 3 times per hour), which requires large-scale equipment. At the same time, hydroponic cultivation tends to be restricted to large-scale farms, and is not suitable for small-scale farms due to the high investment costs and complicated cultivation management. etc., there are drawbacks that make it difficult to introduce.

On the other hand, the above-mentioned rock wool cultivation also has the same drawbacks as the above-mentioned hydroponic cultivation because strawberries are planted in a special medium and fertilizer solution is replenished every day.

It is an object of the present invention to provide a new method for cultivating strawberries that overcomes the drawbacks of the above-mentioned conventional techniques.

``Means for Solving the Problems'' The cultivation method of the present invention that solves the above technical problems consists of ``a culture medium holder made of a pipe material, which is placed horizontally and has a series of planting holes in its upper part, and which is filled with rice husks. It is characterized by a method of cultivating strawberries by using a culture medium as a medium, planting strawberries in the planting hole, and supplying fertilizer solution dropwise from the planting hole.

"Function" The strawberry cultivation method of the present invention having the above structure uses a rice husk culture medium in which the pipe material is filled with rice husks, so due to the inherent physical properties of the rice husks, the heat retention, liquid retention, air circulation, etc. of the culture medium are extremely high. well,
Strawberries can be cultivated well. In addition, since the liquid retention property of the fertilizer liquid is good, the feeding interval of the fertilizer liquid can be shortened.
The daily management of cultivation can be simplified, and since the culture medium has a pipe-filled structure made of lightweight granular aggregates, it is possible to create, dispose of, and regenerate the culture medium using air conveyance means that utilizes aerodynamics. The work required for etc. is simplified,
It has the effect of significantly improving the workability of strawberry cultivation.

Furthermore, in a culture medium in which rice husks with voids between grains are housed in a tube material, the culture medium itself has both adequate liquid retention and liquid permeability.
Taking advantage of these characteristics, artificial means for controlling the culture medium temperature can be easily adopted, such as circulating cold or hot water within the culture medium, or providing a heat retaining layer around the outer periphery of the culture medium. Further, there is an advantage that the structure of the cultivation device is simplified and easy to introduce.

"Example" Hereinafter, a detailed explanation will be given with reference to an example. With reference to FIG. 1 showing the cultivation apparatus of one embodiment of the present invention, the rice husk medium 1 is as follows:
A horizontally placed pipe material 3 (the pipe material in this example is a resin pipe) is used as the culture medium holder 2, and planting holes 4 are successively arranged at the required pitch P in the upper part of the pipe material 3. Light-weight rice husk 5 is filled from one end of this culture medium holder 2 by air conveying means, and both ends of the pipe are closed to form a rice husk culture medium 1. In addition, 7 in the figure is a drain pipe, and 8 is a support.

The rice husk culture medium 1 is placed horizontally and arranged in multiple stages, and a vibro fertilizer solution is placed along the pipe material 3 on the upper outer periphery of the pipe material 3 of the rice husk culture medium 1, and the vibro fertilizer solution is connected to the planting hole 4. It has a structure that supplies fertilizer solution dropwise. In this embodiment, the inner diameter of the pipe material 3 is 100 mm, the pitch P of the planting holes 4 is about 80 mm, and the planting holes 4 are square holes of about 30 mm.

Strawberries are cultivated using the above cultivation apparatus as follows.

That is, - Put a strawberry seedling 9 into the planting hole 4 of the rice husk culture medium 1 by making a depression in the filled rice husk 5 with your fingertips, put a small amount of culture soil around the roots of the strawberry seedling 9, and press it down.

Plant strawberry seedlings 9.

- Then, once a day after planting, the fertilizer solution is dripped from the fertilizer solution vibro to supply the fertilizer solution to the rice husk medium 1.

・Thus, after rooting, the fertilizer solution is supplied dropwise once every 2 to 3 days, and the strawberries are cultivated as usual.

- After the strawberries are harvested, the strawberries that have spread their roots in the rice husk culture medium 1 are pulled out, and both ends of the pipe material 3 are released, and the rice husk 5 inside is pulled out using the air conveying means, similar to the filling of the rice husk described above. , it is refilled with new rice husk 5 and recycled.

Note that the commercially available air conveyance means means a means for filling the pipe material 3 with lightweight rice husks 5 or extracting them from the pipe material 3 by using air pressure or suction power of a blower or the like.

According to the cultivation method of the above example, since the culture medium consists of the rice husk culture medium 1 filled with a pipe, the medium itself has good heat retention, liquid retention, and air circulation based on the characteristics unique to rice husk, and extremely good strawberry cultivation can be achieved. Can be done. After establishment, it is sufficient to supply fertilizer once every 2 to 3 days, which simplifies daily management compared to conventional hydroponic cultivation methods, and also simplifies culture medium creation and regeneration work. Since the air conveyance means can be used, the work required for preparation for cultivation is significantly reduced, and the efficiency of cultivation work is further improved.

Furthermore, since the cultivation apparatus can be set up using pipe material and rice husk as main materials, the entire apparatus can be prepared at a much lower cost and in a simpler manner than in the hydroponic cultivation described above. In addition, since the culture medium itself is extremely lightweight, it has the advantage that a multi-stage culture medium structure can be easily adopted (the support structure etc. are simple due to the light weight).

On the other hand, there are the following application examples as other embodiments of the present invention.

・Part 1 In the rice husk culture medium 1 in which the pipe material 3 is filled with rice husk 5, a small amount of cultivating soil (
(approximately 10% or less) or a small amount of rice husk smoked charcoal or fertilizer powder may be mixed in.

However, it is necessary to keep the amount within a range that maintains the lightweight characteristics for air conveyance.

・Part 2 Utilizing the liquid retention property of the rice husk culture medium 1, supplying hot or cold water to the rice husk culture medium 1 (flowing a small amount of hot or cold water to the lower part of the pipe material 3), intentionally controlling the culture medium temperature, To promote strawberry growth or prevent excessive growth. By using this culture medium temperature control means, strawberries can be cultivated efficiently at low cost.

"Effects of the Invention" As explained above, the strawberry cultivation method of the present invention improves the workability of cultivation, and the cultivation equipment is simple and inexpensive.
It has the advantage of being easy to introduce even in small-scale farms, and has great effects such as further popularizing strawberry cultivation other than soil cultivation and promoting the provision of high-quality and inexpensive strawberries.
