Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention mainly relates to a plant cultivation method for cultivating plants such as vegetables and fruits and vegetables, and a cultivating soil for plant cultivation used therein.

(Conventional technology) Traditionally, soil cultivation and hydroponic cultivation have been the mainstream methods for growing vegetables and fruits and vegetables in greenhouses, etc., but recently there have been improvements in labor saving, measures against continuous cropping problems, and improvements in productivity. Aiming to improve productivity and reduce costs, a rock wool cultivation method that is intermediate between soil cultivation and water V1 cultivation has been attracting attention and experiments are being conducted.

As the name suggests, this rock wool cultivation method uses rock wool as a potting soil, transplants the target plant into this, and then examines the type of plant, the fertilizer absorption status according to the growing season, the weather, especially the amount of solar radiation and temperature, etc. Rock wool is a method of cultivating and cultivating without controlling the amount of fertilizer and water supplied, taking into account the related conditions of rock wool. It is made into fibers by centrifugal force and compressed air or high-pressure steam, etc. and made into a block or bed shape, and is commercially available under the trade name of Rock Fiber.

(Problem to be solved by the invention) By the way, the above-mentioned rock wool cultivation method is attracting social attention as a new field of B industry.

However, the reality is that the equipment investment and running costs are large, rock wool is difficult to obtain, and it is not profitable, resulting in a great deal of confusion for farmers.In addition, disposing of rock wool after use is troublesome. There were some problems.

The present invention was developed in view of the above circumstances, and allows farmers to effectively utilize rice husks that are easily available, is lightweight and easy to handle, and has good workability, as well as allows for effective cultivation of plants at a very low cost. To provide a method for cultivating plants and a soil for cultivating plants, which can improve productivity and obtain sufficient profitability, and can be simply disposed of after use.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention first uses rice husks that have been soaked in water as the main ingredient, and mixes an appropriate amount of soil or artificial soil with the rice husks, and then cultivates them. The method is characterized in that fertilizers suitable for the plants to be cultivated are mixed to form a potting soil for plant cultivation, and plants are sown or transplanted as seedlings and grown and cultivated while being watered at appropriate times.

In addition, the cultivation soil for plant cultivation is mainly made of rice husks that have been soaked in water, and is mixed with suitable soil or artificial cultivation soil.
It is characterized by containing fertilizers tailored to the plants being cultivated.

The soil for plant cultivation is mainly composed of rice husks that have been soaked in water, mixed with suitable potting soil or artificial soil, and either wrapped in a cover such as paper, net, or non-woven fabric, or mixed with a water-soluble binder. It is preferable to form it into a block shape.

(Function) With the above-mentioned plant cultivation method and cultivation soil, farmers can effectively use rice husks, which are easy to handle, as the cultivation soil, making it lightweight and easy to handle, improving workability. , very low cost. Moreover, it is possible to mix not only rice husks but also an appropriate amount of soil or artificial culture soil, mix fertilizers suitable for the plants to be cultivated, and grow and cultivate them while watering, which can be disposed of as is, making it easy to do so.

Rice husk-based soil for plant cultivation can be wrapped in paper, net, non-woven fabric, etc., or mixed with a water-soluble binder to form it into a block shape, making it easier to transport and place on the cultivation bed. Handling work such as installation becomes extremely simple and highly efficient.

(Example) Examples of the plant cultivation method and the soil for plant cultivation of the present invention will be described below.

Here we will discuss an example of cultivating Komatsuna. The rice husks that farmers have left over are soaked in water for about four days (and sterilized at the same time). A large quantity of such rice husks is prepared, and a soil for cultivating plants is obtained by mixing with it a soil or artificial soil such as red]- or loam soil, and a slow-release fertilizer.

As the slow-release fertilizer, coating fertilizer "Long 140" (manufactured by Chisso Asahi Fertilizer Co., Ltd.), which is commercially available as a nutrient leaching-adjusted fertilizer, was used. In addition, the a content of rice husks relative to the total amount of rice husks is blended to be about 65 to 85%.

A cultivation bed or a seedling box is filled with such cultivating soil, and Komatsuna seeds are sown therein, and the seeds are germinated and cultivated while being sprinkled with tap water once every 2 to 30 days.

With this, the germination rate is very good, the root hairs grow well, the petioles are also very good, and high yields can be obtained.

Next, some specific experimental examples will be described. First, prepare three types of soil with rice husk content of 100%, 83%, and 67%, and apply a standard amount of slow-release fertilizer of 85%.
A total of 9 types of soil were prepared with multiples of g being 1.2.3, and 12 liters of each of them was individually placed in a 33 cm long and 44 cm wide
Seedling boxes of e+n and depth 8(2) were filled, and 45 Komatsuna seeds were sown in three rows in each. Then, germinate and cultivate while rinsing with tap water from January 10th to 2nd.
This continued until the 3rd of the month.

The results are shown in Figures 1 to 5. First, the germination rate at the 70th day after sowing was as shown in Figure 1.
Regardless of the ratio, the soil with 100% rice husk was very poor, and the soil with 83% and 67% rice husk had very high percentages.

In addition, as shown in Figures 2 and 3, the growth characteristics of plants at the time of harvest, such as plant height (cm) and living organisms per plant (g), are small in the soil made of 100% rice husk, and 83% rice husk and 07-6. It was very large in the cultivation soil of , and moreover, with the same rice husk 3H ratio, the fertilization amount was slightly different at 1.2.3.

As shown in Figure 4, the number of leaves was lowest in the soil made of 100% rice husk, and highest in the soil made of 8396 rice husk. Leaf color density (
On the other hand, the percentage of rice (green meter display) was higher in the 100% rice husk culture J2. Fine again! No deficiency of i element was observed in any culture-1-.

For this reason, using rice husk alone will cause excessive drying and will not produce good results for plant cultivation, but by adding an appropriate amount of soil to rice husk, good results can be obtained (f%), and it can be used as a potting medium. becomes.

The plant cultivation soil of the present invention, which uses rice husk as its main ingredient, may be used by filling it into a seedling box as described above, or by wrapping it with a cover such as paper, net, or non-woven fabric, or by mixing a water-soluble binder. By forming it into a block shape, handling operations such as transportation and laying on a cultivation bed become extremely simple and highly efficient. Further, it is desirable that the water-soluble binder is a fertilizer that itself contains nutrients.

〔Effect of the invention〕

Since the present invention is constructed as described above, farmers can use rice husk in a movable manner, which is easy to handle, and it is lightweight and easy to handle, improving workability, and plants can be cultivated effectively at a very low cost. Thus, it is possible to obtain a method for cultivating plants and a potting soil for cultivating plants, which can improve productivity and obtain sufficient profitability, and can be simply disposed of after use.
