DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant cultivation soil suitable for use in fields (including fruit trees), paddy fields, house soil, seedling cultivation, pot soil or bed cultivation. It is.

[0002]

2. Description of the Related Art Conventionally, humus or a mixture of humus and natural soil is mainly used as a cultivation soil for cultivating plants such as agricultural crops. The water had to be frequently provided, which was very troublesome.

Therefore, the following has recently been proposed. A granular culture soil comprising a mixture of powdered clay and a water-absorbing synthetic resin has been proposed (JP-A-63-279724).
Publication).

[0004] Further, the main component is a fine powder of a ripe compost or beet moss humic acid material, and a fine powder of an aluminosilicate mineral having a permanent negative charge, and a fine powder of a clay material, montmorillonite, and carboxylate. There has been proposed a crop cultivation soil obtained by adding a binder consisting of methylcellulose, polyvinyl alcohol, and lignin, kneading and granulating (JP-A-62-79714).

[0005] An artificial soil is also proposed in which a surfactant is added to the finely cut pieces of the cedar and / or cypress skin layer (Japanese Patent Application Laid-Open No. 3-139215). In this case, it is disclosed that porous particles, vermiculite or a water retention material is further added to the artificial soil.

[0006]

However, the above-mentioned one is mainly composed of powdered clay and mixed with a water-absorbing synthetic resin, but this lacks the nutrients necessary for plant growth, Fertilization is required.

[0007] In this case, not only the balance of macronutrient elements such as nitrogen, phosphorus, potassium, calcium or magnesium, or trace nutrient elements such as chlorine, boron, iron, manganese, zinc or copper, but also excess nutrients are considered. It was necessary to consider the accompanying excessive concentration.

[0008] In the case of the culture soil composed of the powdered clay and the water-absorbing synthetic resin as described above, when the plant is grown, watering and natural drying are repeated, whereby the culture soil hardens, and as a result, the root growth Or impede water penetration and are not always suitable for plant cultivation.

In particular, recently, in a large city, it becomes difficult to obtain powdered clay, the price of powdered clay rises, and it is extremely uneconomical.

[0010] The above-mentioned one uses a fully-ripened compost, but there is no specific description about this ripe compost, but from the whole description, sawdust and fir husks are added to litter or manure. It is understood that ordinary materials have been fully matured.

Although such ripe compost is preferable for growing plants, it takes a long time to mature such ordinary materials, which is extremely uneconomical. And it was difficult to manufacture in urban areas.

The fine powder of beet moss humic acid material is obtained by drying and pulverizing boiled peat, but it is strongly acidic as it is, so it is necessary to add lime to neutralize it before use, and to add too much lime Greater alkalinity can adversely affect plant growth, and this neutralization requires considerable care.

[0013] The above-mentioned one is mainly composed of finely cut cedar and / or cypress skin layers.
Alternatively, the cut pieces of the hinoki cypress cortex hinder the growth of plant roots because the fibers are intertwined.

[0014] In addition, those containing as a main component the cut pieces of the cedar and / or hinoki cypress skin layer lack the nutrients necessary for plant growth and require fertilization, and therefore have the same problems as in the above case. .

In this case, it includes both components extracted by the extractant and components squeezed by pressing.

The components extracted and / or squeezed from the medicinal plant are not taken by humans, and the components can be directly mixed with a culture substrate for plant cultivation, or
This component is directly blended into a culture substrate for plant cultivation and ripened and / or fermented, or a component obtained by ripening and / or fermenting this component is blended into a culture substrate for plant cultivation.

In the present invention, in extracting components from medicinal plants using an extractant, the extractant is not particularly limited. That is, this extractant is recovered and removed by distillation, or the extract component is extracted with a further small amount of a solvent that is not mixed with the extractant used, and the extract component and the extractant are separated by liquid-liquid separation. Or when mixed with the above-described culture substrate, it can be recovered and removed by heating and evaporating, so that a wide range of extractants can be selected and used.

The components extracted from medicinal plants are not taken by humans, and therefore, there is no problem even if the extractant contains components that are undesirable for the human body.

Of course, when the plant is an agricultural food, the obtained agricultural product is used for edible food, and therefore, it is necessary to pay attention to the extractant.

Examples of the extractant include water, hot water, hot water, at least one selected from lower alcohols having 1 to 3 carbon atoms, acetone, ether and ethyl acetate.

As the lower alcohol, ethyl alcohol is desirable from the viewpoint of safety and handling.

According to the experimental results of the inventor, the medicinal plant
In immersing (H) in water or hot water or boiling water (I) to extract the components, the ratio of (H) and (I) is (B) 1 part by weight,
(H) 5 to 100 parts by weight, particularly 8 to 50 parts by weight, and the extraction time is preferably 15 minutes to 10 days, particularly 30 to 24 hours, most preferably 50 minutes to 12 hours.

In the above ratio of (H) and (I), (H) 1
If (I) is less than 5 parts by weight, the extraction of the components is insufficient and the extraction time is prolonged.
If the amount is more than 1 part by weight, the equipment becomes large and the equipment cost becomes high. Therefore, it is most preferable that (I) be in the range of 8 to 50 parts by weight, particularly 1 part by weight of (H).

Further, the medicinal plant (H) may be prepared with water, hot water or boiling water.
In extracting the components by immersion in (I), if the extraction time is too short, less than 15 minutes, the extraction of the components will be insufficient, while if it exceeds 10 days, the extraction will be limited, meaning Is lost and productivity is reduced,
Most preferably, the extraction time is in the range of 50 minutes to 12 hours.

When the medicinal plant (H) is immersed in a lower alcohol (J) having 1 to 3 carbon atoms to extract the components,
The ratio of (H) and (J) is (J) 2 to 50 per 1 part by weight of (H).
Parts by weight, especially 3 to 25 parts by weight, and the extraction time is 15 minutes to
It is desirable to set it to 24 hours, especially 30 to 12 hours, most preferably 50 minutes to 6 hours.

In the above ratio of (H) and (J), (H) 1
When (J) is less than 2 parts by weight, extraction of the components is insufficient and the extraction time is prolonged. On the other hand, when (J) exceeds 50 parts by weight, water or hot water or hot water is used. In addition, a special device is required, and the size of the equipment is large, so that the equipment cost is high and the price of the extractant is high. Most preferably, it is in the range of ２５25 parts by weight.

When the medicinal plant (H) is immersed in a lower alcohol (J) having 1 to 3 carbon atoms to extract the components, if the extraction time is too short, less than 15 minutes, the extraction of the components will not be possible. On the other hand, if it exceeds 24 hours, extraction will be limited, meaningless, and productivity will decrease,
Therefore, it is most desirable that the extraction time be in the range of 50 minutes to 6 hours.

In this case, the used lower alcohols (J) are recovered by distillation or the like.

In the present invention, acetone,
When using ether or ethyl acetate, or when using a mixture of a plurality of extractants, it is the same as the case where 1 to 3 lower alcohols are used.

In the present invention, the components thus obtained are blended with the culture substrate for plant cultivation so as to have the above-mentioned ratio.

When the medicinal plant (H) is immersed in water, hot water or hot water (I) to extract the components, it may be diluted to the above ratio and used.

By the way, as described above, there are many kinds of medicinal plants, and the medicinal plants are used in different places. Therefore, various kinds of medicinal plants can be obtained. These can be mixed to obtain a raw material for compost.

According to the experimental results of the present inventor, even if the medicinal plants are biased, it is recognized that there is no problem in growing the plants by composting the medicinal plants.

In the present invention, the medicinal plant may be added to the culture substrate as it is. However, the medicinal plant produced by pulverizing the medicinal plant has good dispersibility in the culture substrate. Preferably, the medicinal plants do not necessarily need to be sediment-ripened, but those obtained by sediment-ripening the medicinal plants are desirable because they have an immediate effect on plant growth.

In the culture soil for plant cultivation of the present invention, the medicinal plant (H) to which a component extracted and / or squeezed from a medicinal animal and / or mineral (K) is blended is extremely useful. is there.

With such a constitution, not only the macronutrient elements and the micronutrient elements are further enriched, but also other nutrients necessary for the growth of the plant are enriched, and the immediate effect on the growth of the plant is enhanced. It is advantageous because a mixed state of a substance that develops and a substance that exhibits delayed action is more easily obtained.

In this case, the mixing ratio of (H) and (K) is such that (K) is 1 to 20% by weight, especially 5 to 10% by weight, based on the total of (H) and (K). Range is desirable,
If the compounding ratio of (K) is less than 1% by weight, the effect is poor and there is no point in adding it. On the other hand, if it exceeds 20% by weight, not only does the balance of nutrients necessary for plant growth deteriorate, but also the price becomes significantly high. Not preferred.

In the plant cultivation soil of the present invention, the plant cultivation soil (L) is further contacted with air or water.
Selected from the exothermic substances (M) that generate heat upon touch
Since one kind is blended, it is extremely useful for the following reasons.

That is, the above-mentioned cultivation soil for plant cultivation is packed in a predetermined amount and is provided for distribution, which is opened by a person, applied as field soil, house soil, or cultivation soil for raising seedlings, or an appropriate amount of cultivation soil. Collect the soil and fill it in a pot, plantin or flowerbed,
Is administered.

These operations are performed manually. However, in the winter season, it is extremely painful for the culture soil to cool down and be touched by hand. Shunned.

For this reason, in the winter season, the consumption of the culture soil is remarkably reduced. Further, if the culture soil freezes and hardens, the handling of the culture soil becomes extremely poor and the growth of the plant is adversely affected. In addition, the consumption of the culture soil is further reduced.

In the culture soil for plant cultivation, a hydrated one is also used. However, in the winter season, this culture soil is easier to feel and feel colder than the dried culture soil, and is extremely comfortable in hands. The above-mentioned work becomes extremely difficult to perform because of the pain. In this case, when the culture soil freezes, the handleability of the culture soil becomes worse than that of the dried soil.

However, by blending the exothermic substance into the culture soil for plant cultivation as described above, the temperature of the culture soil is increased, and handling becomes easy even in winter.

By the way, the above-mentioned culture soil for plant cultivation (L)
The mixing ratio of the heat-generating substance (M) and the heat-generating substance (M) varies depending on the culture soil (L) for plant cultivation and the heat-generating substance (M) used. ~ 8
It is desirable to be in the range of 5% by weight.

In the culture soil for plant cultivation of the present invention, if (M) is less than 3% by weight with respect to the total mixed culture (L + M), the temperature rise of the culture soil for plant cultivation may be insufficient.
