Abstract

PROBLEM TO BE SOLVED: To provide a lightweight vegetational soil which is lightweight, easy in transportation and application, and excellent in the sprouting rate of seeding plants, and in which the breakage of sprouts after sprouting and the root breakage are not caused. SOLUTION: A lightweight vegetational soil is made by uniformly adding and mixing plant seeds and fertilizer components in a low water content culture soil in which the water content rate is adjusted to 10 to 45 wt.%, preferably to 15 to 43 wt.%, and it is enclosed in a sandbag having a sprouting permeability. Plant seeds of 2000 to 4000 grains/20 liters and fertilizer components of 0.1 to 2.0 wt.% are added to a low water content soil of water content rate of 10 to 30 wt.% in which a simple substance or a mixture of several kinds of organic or inorganic plant raising material whose original specific gravity is 0.2 or less and which has water-repellent performance is included, and also when water is plenished after application of the sandbag, 0.001 to 0.1 wt.% of a nonionic surface active agent that quickly absorbs the water necessary for sprouting and growth of plants is added. As the fertilizer components, one kind or two kinds or more of microorganism metabolic fertilizer, coating fertilizer, or water-insoluble processed fertilizer are used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight sandbag which is prepared by mixing plant seeds with a low-moisture soil composition mainly composed of composts and bagging the soil. The present invention relates to a lightweight vegetation sandbag which is adjusted to an inappropriate value for germination and to which a plant seed and a fertilizer component are added and which is enclosed in a sandbag having germination penetration.

[0002]

2. Description of the Related Art As a conventional sandbag for greening, a soil and soil such as mountain soil and compost are sealed in a vegetation sandbag with seeds (for example, a mesh net made of polyethylene) in which water-soluble paper on which seeds and fertilizer are attached is bonded. Used as a complete vegetation sandbag, or a sandbag with no seed attached and mixed with culture soil and seed.

[0003]

However, products using earth and sand are heavy and difficult to handle.
There was a limit to the number of pieces transported per transfer, which required a lot of time. Compost and organic materials exhibit extreme water repellency when the moisture content decreases. For this reason, at present, when compost or organic materials are used, by adjusting the water repellency by suppressing the water repellency by mixing approximately 50% of other soil materials with the improved soil to effectively absorb moisture. I have to use it. Such an improved soil has a high moisture content, that is, a state in which plant seeds can germinate. If seeds are added to the soil, germination starts during storage and germination once starts. When it is moved by, it is susceptible to damage such as root breakage or broken buds, and there is a risk that sufficient greening will not be achieved after use. If the moisture content is reduced to alleviate such a situation, poor water absorption due to water repellency occurs, and there is a problem that sufficient germination and growth cannot be expected. The present invention suppresses germination before use by preventing water repellency in a low moisture state, prevents sprout breakage and root breakage due to pre-germination, facilitates storage and transportation, and enhances workability of application and the like. It is an object of the present invention to provide a lightweight vegetation sandbag that can be used.

[0004]

To achieve the above object, the lightweight vegetation sandbag of the present invention has a water content of 10 to 45% by weight,
Preferably, plant seeds and fertilizer components are added to low-moisture cultivation soil adjusted to preferably 15 to 40% by weight, mixed uniformly, and sealed in a sandbag having germination penetration. In addition, a water content of 10 to 30% by weight containing 20% or more by volume of a simple substance or a mixture of several kinds of organic or inorganic plant growing materials having an actual specific gravity of 0.2 or less and having water repellency. Non-ionic surfactants capable of rapidly absorbing the water required for germination and growth of plants when water is replenished after sandbag application to low moisture soil
0.1% by weight is added and sealed in a sandbag. Furthermore, the lightweight sandbags contain 2000 to 4000 plant seeds and 0.1 to
2.0% by weight of a fertilizer component is added, and the bag is packed in a bag with the moisture content kept at 10 to 45% by weight.
Mix in proportions. As the fertilizer component, one or more of microbial metabolic fertilizer, coating fertilizer, and poorly water-soluble processed fertilizer are used.

[0005] The culture soil is 10 to 45% by weight, preferably 1%, which is unsuitable for germination of plant seeds when water is retained (when not used).
It is maintained at 5 to 43% by weight, and when water is added by watering or rainfall after use, water is sufficiently absorbed to adjust the water to be suitable for germination of plants. The vegetation sandbag obtained according to the present invention does not require a drying step because the seed is mixed with the low-moisture culture soil, and does not cause a decrease in germination due to heat damage to the seed. By selecting the bag material according to the plant germination form (monocotyledon, dicotyledon), it can be used for almost all plants for greening. Does not occur. Even if the vegetation sandbags are not used immediately after being transported to the site, if they are stored under rainfall, there is no risk of germination before installation, and the introduced plants can be stably established. It has the property that the introduced substance germinates by obtaining water supply by rainwater, moisture absorption or partial flooding. The vegetation sandbags of the present invention can be used not only for greening but also for general plant cultivation (agriculture and horticulture), as well as for desert greening.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The water content (water content) is 10 to 45.
A plant seed and a fertilizer component were added to a culture soil adjusted to 15% to 43% by weight, and the mixture was enclosed in a sandbag having germination penetration. The moisture content of the culture soil is adjusted to 10 to 45% by weight, which is unsuitable for germination of plant seeds, by mixing soil components. If it is 10% by weight or less, the germination rate is poor, and if it is 45% by weight or more, germination is insufficient.

[0007] The culture soil is prepared by adding a nonionic surfactant (a water-absorbing promoter that reduces the water repellency of soil and absorbs water to the maximum of soil particles) to a composition comprising an organic substance and an inorganic substance. Non-ionic surfactants include glycerin fatty acid ester, sorbitan fatty acid ester, sucrose fatty acid ester, polyoxyethylene alkylphenyl ether, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene as described in Japanese Patent No. 2044124. Block copolymer, polyethylene glycol fatty acid ester, one or two selected from polyoxyethylene sorbitan fatty acid ester,
H. L. It has a B value in the range of 8 to 18, and is usually 0.005 to 0.5% in a greening growth base composition comprising 90 to 50% by volume of an organic composition and 10 to 50% by volume of an inorganic composition.
1% by weight.

[0008] The sandbag of the present invention is about 1 /
Easy handling due to weight of 2. The culture soil of the present invention, when water is absorbed in the sandbag, volume expansion occurs,
The shape after construction is stable. When used for concrete frames, etc., it is possible to alleviate problems such as settling and slippage, and to alleviate poor germination penetration due to insufficient filling of culture soil and lifting of bag material generated by plants at the time of germination. it can.

[0009] Furthermore, the lightweight sandbag is used for 2,000 to 4,000 plant seeds per 0.1 liter of low-moisture cultivated soil.
1 to 2.0% by weight of fertilizer component and water content of 10 to 45
Weight percent and packed in a bag. As a component of the low-moisture cultivation soil, a compressed organic material having a water-absorbing resilience is used in a volume ratio of 3 to 3.
Mix at a rate of 40%. If the volume ratio is 3 or less, moisture retention is not sufficient, and if the volume ratio is 40% or more, the moisture content becomes excessive. As the fertilizer component, one or more of microbial metabolic fertilizer, coating fertilizer, and poorly water-soluble processed fertilizer are used. Table 1 below
5 shows the change of moisture content and germination characteristics of various low moisture cultivation materials.

From Tables 1 to 5, it can be seen that there is a large difference in the germination initiation characteristics between the material having a large dry specific gravity (heavy material) and the material having a small dry specific gravity (light material) due to their own water content. I understand. That is, germination can be suppressed even when the moisture content is 20 to 40% in the cultivated soil mainly composed of a material having a large specific gravity. However, when the cultivated soil is mainly composed of light weight peat moss or the like, the germination can be performed up to about 40% by weight. Suppression is possible, and if it is 45% by weight or more, germination may occur during storage. When seeds are mixed and stored for a long time regardless of the specific gravity of the cultivation soil, the added seeds all need to have a moisture content of about 10% by weight in a germination-inhibiting moisture state. It decreases significantly.

Next, each material used will be described. ○ Cultivated soil materials Organic: crushed coconut shell, peat moss, bark compost, compressed organic matter, sludge compost, livestock compost (woody livestock manure, cattle manure, pig manure, chicken manure). Minerals: Pulp sludge firing, ore foam firing, porous volcanic eruptions. Nonionic surfactants: For example, water absorption promoters, Honshu afforestation
Rain power ”. ○ Fertilizer: microbial metabolic fertilizer, coating fertilizer, poorly water-soluble processed fertilizer. ○ Plant seeds: seeds of various herbs, woody plants, flowers ○ Bag material, (sandbag with germination penetration): polymer Material: Cloth woven with film yarn such as polyethylene, polypropylene, etc. Natural Material: Linen cloth, coconut fiber cloth, cloth woven with rayon yarn, etc. (non-woven fabric without specific through holes).

In the above-mentioned culture soil material, the ore foaming fired material is a fired and crushed material such as perlite, obsidian, rhyolite and serpentine, and the porous volcanic ejecta is pumice or ragstone. , Shirasu soil, Kanuma soil, etc. Examples of microbial metabolic fertilizers include IB (isobutylidene 2 urea), CDU (crotonylidene 2 urea), ureaform, oxamide, guanylurea, which hydrolyze or biodegrade.
Examples of the coated fertilizer include various coated nitrogen fertilizers such as LP coat, and examples of the poorly water-soluble processed fertilizer include IB Kasei Birdy Large (Ryoka Agriculture), a biodegradable metabolic fertilizer, and Micrea (Nichito Kagaku). In the bag material, the non-woven fabric having no specific through-holes is a non-woven fabric that can be broken by germination pressure and usually contains 10% or more of pulp fibers, or a chemical fiber is a water-decomposable binder ( Nonwoven fabric entangled with polyvinyl alcohol).

In the culture soil material, the compressed organic material is a block-like material obtained by compression-molding powdery materials such as peat moss, crushed coconut shell, and sawdust into about 1/5 to 1/8 by pressing. In the case of a bruise or the like, the block shape is maintained, but it easily collapses due to the absorption of moisture and restores to the volume before molding and compression (5 to 8 times water absorption restoration). In the present invention, not only such a molded product, but also a defective molded product or a crushed molded product can be used, but the water absorption recovery of the product itself is only about 2 to 3 times.

As the fertilizer component, one or more of a microbial metabolic fertilizer, a coated fertilizer (a resin-coated slow-release fertilizer, for example, High Control (Chisso Asahi), and a poorly water-soluble processed fertilizer) is used. Although it is not possible to specify the composition based on the volume of the culture soil, the place of use, etc., it is usually used in an amount of 0.1 to 2.0% by weight. Therefore, it cannot be specified, but generally about 2000 to 4000 grains per 20 liters of the culture soil, and usually about 3,000 grains are standard.

The bag material and the bag combination are selected according to the germination form of the plant seeds, the purpose of use, the topography of the application site, and the like. It is only necessary that the bag does not leak a large amount of culture soil, and considering the germination suitability, when using dicotyledonous plants, the minimum match of specific through holes is 3 mm or more, when using monocotyledonous plants Needs to be 0.5 mm or more. In the case of using germinating seeds or rhizomes, a material having no specific through-hole such as a nonwoven fabric can be used.

The vegetation sandbags obtained according to the present invention are mainly made of organic or inorganic low-moisture cultivated soil, and are mixed with plant seeds and fertilizer components, and are packed and bagged. . Since the seeds are mixed with the low-moisture cultivation soil, the seeds do not require a drying step by warming, and do not cause a decrease in germination due to failure in heating the seeds. By selecting the germination penetrable bag material used as the encapsulation material according to the plant germination form (monocotyledon, dicotyledon), it can be used for almost all greening plants, and the seeds are uniformly mixed with the culture soil. It germinates all over and does not cause vegetation bias. Moreover, even if the vegetation sandbags according to the present invention are not used immediately after being transported to the site, if they are stored under rainfall, there is no risk of germination before installation and the introduced plants can be stably established. If a compressed organic material that restores (absorbs and expands) water is used as a material to be mixed with the culture soil, the shape of water absorption due to rainfall after installation is stabilized.

Further, in the case of an enforcement requiring traffic restriction on an expressway or the like, the use of low-moisture lightweight sandbags increases the transport amount per operation, and can reduce the number of material transporting vehicles. In addition, while the conventional method of spraying organic growth base material with a pumping device requires plant space in addition to the material storage area, when applied using the product of the present invention, it is equivalent to the daily work volume If work is carried out, there is no suspension of work equipment during non-working hours (eg, at night)
This leads to a reduction in traffic regulation time. In addition, since the production of a small lot is possible, it is possible to variously adjust the composition of the seeds to be used, and it is possible to easily introduce a design greening method (flower letters, etc.).

[005 6] In addition, in the case of construction that requires traffic restrictions such as highways, by using a moisture lightweight sandbags, increased transport amount per one weight loss of material handling work vehicle can be realized. In addition, the conventional method of spraying the organic growth base material with a pumping device requires plant space in addition to the material storage area, whereas when applied using the product of the present invention, it is equivalent to the daily work volume If work is carried out, there is no suspension of work equipment during non-working hours (eg, at night)
This leads to a reduction in traffic regulation time. In addition, since the production of a small lot is possible, it is possible to variously adjust the composition of the seeds to be used, and it is possible to easily introduce a design greening method (flower letters, etc.). In the case of conventional products with a high moisture content, sandbags freeze and become block-like at the construction site during winter construction, etc. Could not be done. For this reason, the heat insulation treatment is usually performed on site, but when the treatment is not taken, the winter construction must be abandoned. On the other hand, since the product of the present invention has a low moisture content, it does not freeze even at low temperatures, retains appropriate flexibility, and can be stably installed even on a portion having unevenness on the ground surface, thereby making it possible to carry out winter construction in cold regions. Allowances have been expanded and winter employment can be promoted in the target areas.
