Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medium for cultivating crow fiber plants, which is characterized by being made of glass fibers.

The crow fiber plant cultivation medium of the present invention is useful for raising seedlings and cultivation of all herbaceous and woody plants, such as legumes, vegetables, flowers, flowering trees, and trees, as well as for elemental test cultivation. In addition, the crow fiber plant cultivation medium of the present invention has a very high bee volume, is very easy and efficient to handle, and 2 is an extremely advantageous plant cultivation medium for industries that can industrially mass-produce products with stable quality. It is. 2. The medium for cultivating crow fiber plants of the present invention has excellent physical properties but is chemically completely inert. In other words, it is extremely useful for strict element test cultivation.

As an example, a machine that was developed after the war and is now widely used in over 90% of all rice paddies. Explain.

Regarding box seedling raising for conventional 2-machine rice planting.

Generally, excavated soil, field soil, rice soil, etc. have been used for cultivation soil. Cultivating soil made of these natural soils is prepared through processes such as breaking down two piles, digging them out, sieving them into five particles, disinfecting them, adding fertilizer, and adjusting the acidity.
Performing this kind of work as agricultural work for ordinary farmers is extremely complicated, extremely hard work. In addition, natural soil, which is the raw material for cultivation soil, may seem to have an infinite number of cavities, but in reality, the quality that can be used for raising seedlings is extremely limited. An increasing number of farmers are now purchasing and using ready-made products rather than commercial manufacturers. On the other hand, as the demand for potting soil increases, manufacturers are facing a shortage of high-quality materials that can be used as raw materials.
I started having trouble acquiring it.

Additionally, for farmers who raise seedlings, potting soil made from natural soil generally has a bulk specific gravity of around 1.

In addition to being heavy and inconvenient to handle, it also had the serious drawback of unstable seedling growth because the quality of natural soil varies and is inconsistent.

As a result, raw materials that can be industrially mass-produced attracted attention.
First, mats for raising seedlings made of polyurethane foam molded into a mat shape were developed, and mats for raising seedlings molded from rice husks and straw were also proposed, but due to some difficulties in raising seedlings, the former is no longer used today. It has disappeared, and the latter is only used in small quantities locally. Recently, mats for raising seedlings using organic fibers such as pulp and cardboard have been developed and efforts are being made to popularize them, but there are still doubts as to their practicality. In addition, the present inventor first proposed a seedling mat using rock wool, which is an inorganic fiber, but as a result of repeated efforts, two more
We have arrived at the present invention. That is, when rice seedlings and the like are raised using the plant cultivation medium made of glass fiber of the present invention, the medium is extremely lightweight and very convenient to handle, and the results of raising seedlings are extremely excellent, as will be described later. As shown in the examples.

Origin 2 The Karafu fiber, which is the raw material for the glass fiber plant cultivation medium of the present invention, is made of extremely fine fibers of about 6 to 10 microns, similar to the rock wool that is the raw material for the rock wool mat mentioned above. Although the components of rock wool are soluble and active, the glass fibers related to the present invention are natural fibers.

The two have different properties in that the components are insoluble and inert. In addition, the glass fiber is used as a long material, for FRP, for filters, and for insulation, heat retention, and soundproofing materials for buildings, refrigerators, industrial equipment, etc., and the glass fiber is used as a medium for plant cultivation. It has never been done.

However, the present inventors have discovered that crow fiber is an extremely excellent medium for growing plants. As mentioned above, the glass fiber is extremely thin and no components are eluted.

For example, 1 g of glass fiber with a thickness of 5 microns has a length of about 1
It corresponds to five axes and has a very large surface area of several thousand cl. This surface area approximately corresponds to the surface area of 1 g of silt particles, where the coarse portion plays a skeletal role in the soil and the thin portion contributes to physical and chemical reactions. Also, for example, now, using the glass fiber of about 1009, 60 cm
When molded into a pine tree with a volume of
Holds approximately 2,000 cc of water, and empties approximately 1°,000 celsius
It becomes C. That is, the solid phase is a little less than 10%, the aqueous phase is 60%, and the empty phase is approximately 60%. This is a type of hydroponic cultivation medium that contains an extremely large amount of air. Compared to the approximately 6% air contained in water used in general hydroponic cultivation, this is an extremely superior medium that contains approximately 10 times more air. ↓It can be said that it is a medium for cultivation.

In this case, the fact that the crow fibers are inert and do not elute any of their components means that they are completely worthless materials according to the conventional idea of cultivation soil. It is the best material for this purpose.

In other words, crow fiber is an extremely excellent culture medium material that can be cultivated by scientifically applying the types and amounts of nutrients needed at the right time and in accordance with the type and growth stage of the plant being cultivated. It can be used as.

However, on the other hand, the glass fiber.

Although its components do not elute at all and are inert, when used as a medium, it has extremely excellent physical properties such as ``double'', which means that when using the crow fiber as a cultivation bed, for example, using natural culture soil. When covered with soil and cultivated, the cultivated plants will grow due to the synergistic effect of the excellent physical and physicochemical advantages of the crow fiber cultivation bed and the active chemical properties that elute the ingredients contained in the natural soil. , has excellent growth. An example of this can be seen in the IkuUi example described below.

In other words, raised seedlings can grow extremely healthily by actively elongating their roots in the sufficient water phase and sufficient airflow maintained in the cultivation bed, and making full use of the inorganic components of the covering soil. It is.

The glass fiber plant cultivation medium of the present invention can be composed of glass fibers as a molded body having a certain volume or as an amorphous nodular aggregate having a certain volume. In this case, either long fibers or short fibers can be used, but usually short fibers are used. Further, during molding, the short fibers are usually molded using a water-soluble polymer adhesive as a binder. In addition, the fibers can be molded by arranging them horizontally, vertically, or in any direction, but if they are molded by arranging them in the vertical direction, it is extremely easy for the roots of the plant to penetrate into the medium, and the growth of the roots increases. is very active.

Furthermore, the medium for cultivating crow fiber plants of the present invention is as follows.

If necessary, we can adjust the pH, treat with surfactants to improve water permeability, or add fertilizer components.'! ! Ta. Other inorganic or organic fiber materials can also be blended. In addition.

A binder may or may not be used when aggregating into a molded body or a lump of a certain volume, but if it is used, the pH can be adjusted using an acidic or alkaline binder.

Example (1) As a medium for cultivating glass fiber plants of the present invention.

It is convenient to use a commercially available fertilizer for hydroponic cultivation, with 3 g per serving, as additional fertilizer using Chiyoda Kasei 550 and sulfuric acid.

As shown in Table 6 above, the results of seedling raising according to the 9 Examples of the present invention are lower than those of the comparative example using conventional cultivation soil, that is, healthy seedlings with excellent plant height were grown. We were able to.

Incidentally, the seedlings of Examples can also be used as planted seedlings for soil cultivation.

It can also be used as is as a seedling for planting in hydroponics.

Example (2) (1) N151 was added to the glass fiber plant cultivation medium of the present invention in which short glass fibers 1201 were molded into a mat shape of 28 cm x 58 cm x 2 cm using a water-soluble carbolic acid resin adhesive as a binder, along with the acidifying agent sulfuric acid 3I. / (ammonia sulfate), P2O51,7& (superphosphate lime), Kzo

Furthermore, in the same way as the ``hate → + elbow'', it was finished by acidification treatment, addition of fertilizer, and treatment with a surfactant.

Incidentally, the treatment can also be carried out by mixing the acidifying agent and the fertilizer with the two synthetic resin binders.

The glass fiber plant cultivation medium of the present invention described in Section 2 (1) and (2) was used as a seed bed, and 200 g of seed rice germinated in the shape of a pigeon breast was sown on each, and then natural soil adjusted to pH 5 was covered with natural soil. We conducted a seedling-raising test on young rice seedlings.

As a comparative example, a commercially available Jujo mat (manufactured by Jujo Paper Industries)
The same young seedlings as in the example were raised using Pillomat (manufactured by Kyusan Paper Industries) and granular culture soil made from natural soil (manufactured by Kureha Chemical). In addition.

The ten-row mat and pillow mat were covered with the same soil as in the example.

According to Table 4, the results of raising young seedlings in Examples (1) and (2) of the present invention are in accordance with the general healthy seedling standards (1).
Plant height 10-13cm, dry weight 101g or more - 2 leaf age 22
2 leaves color 4-5. This is a noteworthy point as it satisfies the following criteria:

In addition, in the mat of longitudinal fibers of Example 2.

The rooting of 14°i is outstanding. By the way, the seedlings of the comparative example.

Although the seedlings were taller and appeared to have better growth than the seedlings of the examples of the present invention, they had a lower dry weight and were therefore elongated seedlings with a lower degree of fullness at °C. For healthy seedlings, as long as they meet the 2-leaf age standard, a plant height of 1Qcm is sufficient, and it is preferable that the seedlings are so-called zunguri seedlings, which have 5 leaves upright without growing more than 13cm, and are highly full. .

Using the crow fiber plant cultivation medium of the present invention.

When raising rice seedlings, raising healthy seedlings, which previously required advanced seedling-raising techniques using cultivation soil, has become extremely simple for ordinary farmers in terms of seedling-raising techniques and medium handling. Become.
