Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides: 1: A culture medium with conditions suitable for the generation and growth of young tffi by simply adding water to the shell without using soil. This relates to artificial cultivation soil that can be used.

Artificial soil has been widely used in the past for the purpose of facilitating the creation of a medium with conditions suitable for the generation and growth of young plants, and for producing large quantities of homogeneous seedlings.

This type of artificial JU± is generally made from natural raw materials such as soil, sand, compost, plant cloth, etc., and non-synthetic resins. lK
is blended to form appropriate solid, liquid and air layers in the soil, improving water retention and 'r! -Conditions such as water resistance, breathability, heat retention, etc. are adjusted to suit the conditions.

However, as agricultural mechanization or agricultural management becomes more complex, and the amount of artificial 18F used increases, it becomes difficult to collect large quantities of raw materials (1), and the properties of natural raw materials 1-1. The problem arose that it was difficult to produce artificial soil products on a one-leaf scale, and that the demand could not be adequately met.

Therefore, the present invention focuses on using earth and sand that has been conventionally used.

Natural products such as rocks and agricultural by-products cost 151 yen per month! River J-
It is possible to mass produce on an industrial scale using raw materials that are easily available commercially and of uniform quality (in addition, a medium with optimal conditions for the generation and growth of seedlings). There is one person who has been given Z''cK for the purpose of providing soil.

In other words, Honkomei's person-L', Jj'5 soil has a volume ratio of fired Barmy 1--1 light and pea l-moss of 1:1.
-9:1 if-compound and super absorbent polymer $5) powder is added in an amount of 0.1 to 1% of the volume of the mixture. If you add water to 4j, it becomes J. In addition to this, the super absorbent Pl: polymer absorbed water and gelled immediately, and baked Barmy 1-:, L-lye 1~ and Beet-E-s were dispersed in this gel phase. A structured medium is formed.

Calcined vermiculite 1~ used in the present invention τ is obtained by crushing raw stone into 1-piece pieces, grading the C particle size to about 0.5-5 mm, and firing this at 500-1000°C to scatter crystallized water. It is an anhydrous porous mineral that has opened the interstices of the crystals, has a small bulk specific gravity, and has water absorption, water retention, and air permeability.
It affects various properties such as air retention.

Bee 1~Moss is used in the present invention as a pl-l adjustment material. That is, Vermicular 1~ is l
) exhibits neutrality of about H7.0, or is l in plant culture medium.
A weak acidity of about 5.5 to 6.8 is preferable, and P1 to moss, which speeds up acidity, is blended with Vermicolite to make it C weakly acidic. At this time, add the baking powder to 1 (1) of baked permil 1 rai 1 ~ and pea 1 - moss.

The high 1ν water-based polyester used in the present invention C can be maintained in the weakly acidic range of 6,11. -IJ, generally in the form of white powder, several hundred times larger than your own car.
This is because it has the property of absorbing water (below 1I) and solidifying it in the form of a glue. , polysodium acrylate crosslinked product system, polyvinyl alcohol crosslinked product system,
Although the types of poly-dylene A-kinetsu nide cross-linked tongues are commercially available and artificial, in the present invention, it has a 1:!L water absorption capacity (-C) which hardens water into a gel-like form. , which type η
The amount of superabsorbent polymer used in the present invention is 0.1 to 1% by volume in a mixture of baked barcury 1 and P1 to Stainless Steel. Range (mixture: 0.1% by volume, less gelling effect)
<, The water retention effect of the culture medium and the water transpiration suppression effect are 1/11'
I; Yes. On the other hand, if it is used in an amount greater than 1% by volume, the amount of water retained will be too large and the C medium will have poor aeration.

? The r'C water-absorbing polymer can be blended in the minute amounts mentioned above, but calcined vermiculite 1~ can be effectively used as a carrier to uniformly distribute such minute amounts. 'ru. 1. In other words, calcined vermiculate is lightweight (C' has a small bulk specific gravity) and has a large surface area due to its large number of pores. Even powder can be uniformly dispersed, and scattering of powder can also be prevented. In addition, since calcined vermiculite 1- is physically and chemically stable and is in an almost dry state, there is a concern that the super absorbent polymer may change in quality and absorb water even during storage of the compound. %stomach.

The artificial 1Δ material of the present invention, which is made by blending each of the above components in a predetermined ratio C', is in the form of dry, lightweight granules as it is, and is easy to handle and has a long shelf life. When using it as a culture medium, please refer to the previous section. , : Add water to this (from this, it will gel)
Inside, the baked vermicular 1 - binding - 1 - moss is formed as a solid substance, 1 layer (in a closed state, solid layer), and a balance layer containing a gas layer is formed. . Tsunawa I5, water formed from super absorbent porin-j, ・) 11
1. For the gel phase, remove the water-retaining solid phase for 11 minutes, turn it into a solid, and then heat the solid layer. The porous pores and the interstitial gaps of the P1-moss create an air layer, and the gravity water absorbed into the pores of the fired Vermi A-Kolai 1~ and the fiber gaps of the P1~7S creates a liquid layer. 'The thing that can be raised is -C monkey.

The thus-depleted culture medium structure is fixed to stably support the seedlings (determines the specific gravity required as Δ, and has optimal water retention for seedling development and growth. 1) 1° water permeability, air retention. 1

In addition, one component of the fertilizer necessary for plant growth can be obtained by adding ζ (1^) of raw material to the mixture as appropriate using Book 5. However, various fertilizer components can be mixed in advance with the soil composition of the present invention.

The present invention will be further explained below with reference to Examples.

Example: 3 volumes of calcined vermiculite and 1 volume part of peat moss were mixed, and the volume of this mixture was 0.5 vol.

The artificial culture soil of the present invention was prepared by blending a super absorbent polymer (graft polymer of acrylic yarn tops, trade name "Aqua Keep", manufactured by Tetsusei Kagaku Ichiha (1)) in an amount equivalent to %. .

After leveling the surface of the medium and sowing Koshihikari rice seeds, we covered it with the above-mentioned artificial soil and conducted a seedling-raising test.

For comparison, we used a commercially available
A seedling-raising test was carried out in the same manner as C using clay material). Show C.

From Table 1, it can be seen that when using the inventor's I18 soil, the frequency of irrigation was slightly lower than that of the commercially available soil, and the condition of the seedlings during life was superior.
