2. Description of the Related Art In recent years, sports such as golf, soccer, tennis, rugby, baseball, and horse racing have become increasingly popular, and the importance of sports turf has been recognized (see turfgrass research,
Vol. 23, No. 1, pp. 38-50, (1994
Year)). Regarding the creation and management of grass at such a stadium, appropriate grass species, appropriate and short-term creation methods, appropriate flooring, underground structures, etc. are required according to various situations. Lawns can be broadly classified into cold-season turfgrass and warm-season turfgrass. In general, cold-season turfgrass photosynthesis and photorespiration of the C3 cycle (reductive pentose phosphate cycle) by RuBP (ribose 1,5-bisphosphate) carboxylase. Turfgrass generally has a C4 cycle (enolpyruvate phosphate) carboxylase by PEP (enolpyruvate phosphate) carboxylase, has a high carbon dioxide fixation rate, and has almost no light respiration. Is physiologically different from
As a result, the plants have different ecological characteristics such as suitable growth temperature, drought resistance, freezing resistance, heat resistance, negative resistance, etc. (turfgrass research, No. 23
Vol. 2, No. 145-157, (1995)).

[0003] In addition, when the lawn is viewed from the creation method, there are roughly divided into a seed propagation method and a vegetative propagation method. The cold-season turf grass which is a C3 plant is mainly based on the seed breeding method, and the warm-season turf grass which is a C4 plant is mainly based on the seed propagation method. It depends on the vegetative propagation method. In the case of cold-season turfgrass seed breeding type, before sown, turf seeds and artificial granular culture soil, and seeding with an appropriate amount of water to promote germination to cover the artificial granular culture soil Shortening the period has been done. However, in warm-season turfgrass, it is practically used for seed production. For example, Kosa grass (including Hime Kosa grass), zoisia species including wild turf grass, bermuda grasses including Tifton and Tifd Wharf, and St. Augustine etc. The development is generally carried out by a vegetative propagation method using the stolon (stron, lysosome).

[0004] Propagation methods using claw stalk include methods such as upholstered turf, planted turf, and sow turf. For example, the upholstery method is
The lawn can be completed in as little as two months, but strip sodding has recently gained attention in the United States given the time, location, and transport of heavy soiled sods to where they are needed. Despite this, (Shiba Grass Research, Vol. 23, No. 2, pp. 163-167, (19
1995)), considering the road conditions in Japan, it cannot be said that this method is suitable for creating a lawn with a large area such as a stadium. In addition, in this method, the deteriorated brooms and undegraded dead plants (thatch) contained in the upholstery are directly brought to the land, so that the maintenance and management after completion is troublesome. On the other hand, the planted turf and sown turf methods can renovate the stalk and improve the soil environment in the rooting area, and can produce a dense and stable lawn. However, depending on the weather conditions, it takes a considerably long time of around six months to complete the construction of the lawn.

[0005] As a method of overcoming these problems in the propagation by the claw stalk and revitalizing the lawn in a short period of time, Japanese Patent Publication No. 52-34534 discloses a method in which a crab-shaped lawn from which soil and sand have been removed is spread and planted. There is disclosed a method in which a soil is covered with a culture soil and further coated with an aqueous solution containing polyvinyl alcohol, silica or the like to form a film. However, although such a method can overcome the difficulty of management, the vegetation method is quite complicated. Further, Japanese Patent Application Laid-Open No. 4-31642 discloses a method in which a stretched turf is cut into strips, mixed with soil, and planted. In this method, too, the method of cutting into strips or mixing with soil in an amount of 2 to 5 cm with respect to the planting area is quite complicated. Also, as for the soil of sports turf, it is best to increase the root activity in order to withstand severe stress such as short cutting and unbearable treading pressure. It is soil (Japanese Journal of Soil Fertilizers, No. 65
Vol. 5, No. 514-521 (1994), Turfgrass Research, Vol. 23, No. 1, pp. 51-57, (1995
Year)). However, in the case of sandy soil, it is conceivable to provide fertilizers and other nutrients for the lawn as much as possible if the soil is to be developed quickly. However, sandy soil has no fertilizing ability, and liquid fertilizer must be fertilized frequently. In addition, fertilizers are more likely to flow into the sand and soil than are absorbed by the lawn, causing a problem of environmental pollution. In addition, when simply mixing an appropriate amount of solid fertilizer into the soil and covering the soil, there is a part where the fertilizer concentration is high and the lawn is damaged due to burning,
Up to now, the use of solid fertilizer simply mixed with cover soil for both sown and planted turf has not been practiced in the construction of lawns.

[0006] Regarding sports turf in Japan, it is considered that the national stadium is currently created and managed according to the highest technical level. As a result of various studies, the lawn was basically selected from Bermuda-type Tifton turf, a broad-stalk type turf with strong fertility in June-August. For perennial ryegrass, we maintain the lawn for a year through winter overseeding. The upper part of the lawn floor structure is also made of sand, but the underground structure is a facility that requires considerable expense. It is difficult to maintain and maintain such facilities at any stadium. Under such circumstances, it is considered important to establish technology to promote healthy growth and greening of the lawn, and to create facilities that can reduce environmental pollution and can be implemented at a realistic cost.
There has been a long-awaited need for a lawn-producing material or a method for creating a grass for a short time, which does not require a complicated underground structure with little environmental pollution.

[0007]

As described above, a method for constructing a large-scale sports turf in a short period of time, which can practically solve the above-mentioned various problems, has not yet been established. The present invention has been made in view of such a situation, so that a warm-field lawn, which is a C4 plant, can grow roots quickly and many times from its broom, without burning, without fertilizing frequency, and can be planted turf. It is an object of the present invention to provide a lawn creation accelerating material with a low environmental pollution in a short period of time for a large-scale lawn of a cuff lawn, and a lawn creation method using the same.

[0008]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, streaked the crests cut to a length including 1 to 3 nodes at substantially regular intervals, When growing artificial granular culture soil granulated by adding an appropriate amount of fertilizer component and humus at a concentration lower than that of ordinary fertilizers alone or as a mixture with sandy soil, it is possible to grow grass in a short period of time That is, the present invention has been achieved. That is, according to the present invention, turf stalks are streaked almost at regular intervals,
It contains 0.01 to 5% by weight of fertilizer, 0.2 to 4% by weight of humus, is adjusted to pH 4.5 to 7.5, and has a particle size of 0.1 to 0.1%.
The present invention relates to a planting turf formation accelerating material containing an artificial granular culture soil granulated to 3 mm as an active ingredient, and a lawn formation method using the same.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION As a lawn growing in the present invention,
For example, zoisia including Tsuchifon, wild grass, etc., Tifton,
It is a warm grass turf of C4 plants such as Bermudagrass including Tifd Wharf and St. Augustine. The fork stalks are planted 50 to 200 g / m ² at almost regular intervals on a lawn ground, which has been ground using washing sand or the like for lawn formation, on which the artificial granular culture soil of the present invention is placed. Is covered with soil as a turf development accelerator. The above interval is 10-40c
m, preferably 10 to 20 cm. 1-3 for covering soil
kg / m ^2, preferably using artificial granular culture soil 1.5~2.5kg / m ^2. The soil covering with artificial granular culture soil is
The thickness is 10 mm or less, preferably 5 to 10 mm.
It can also be used to form part of the surface of a lawn land where sows are sown. The use of the artificial granular culture soil promotes germination and root growth from the crest stalk.

In the present invention, the artificial granular cultivation soil used for the covering soil as a turf formation accelerator contains 0.01 to 5 fertilizers as an active ingredient.
%, Preferably 0.01 to 2% by weight. More specifically, nitrate nitrogen is 0.002 to 0.005.
Wt%, ammonia nitrogen 0.03-0.04 wt%,
Total phosphorus about 0.2% by weight, water-soluble potassium 0.04 to 0.08
% By weight and at least 0.02% by weight of magnesium. It also contains 0.2-4% by weight of humus. The pH is 4.5 to 7.5, preferably 6 to 7, and the particle size is 0.1 to 5 mm.
Granulated so as to be in a range of ３3 mm. The particle size distribution may be wider than that of the granular soil used for seed germination, and granulation is easy. The retained fertilizer is gradually released over about one month, so that fertilization of other fertilizers can be omitted or the amount used can be reduced in the early stage of germination and rooting. However, since the content of the fertilizer component is 5.0% by weight or less, even if the artificial granular culture soil is used in a large amount, for example, 5 kg / m ² or more, there is no risk of burning. The artificial granular culture soil used in the present invention can be produced as follows. Dry and coarse pulverization of raw material soil such as mountain soil, field soil, volcanic ash soil,
Add an appropriate amount of water, a desired amount of fertilizer components and humus, adjust the pH as needed, pulverize using a continuous vibrating mill, etc., and mix evenly to obtain a soil mixture. The mixture is sent to a mold granulator, and about 1% solution of a water-soluble polymer such as polyvinyl alcohol, carboxymethyl cellulose and methyl cellulose is added and granulated.

[0011] In order to create a lawn by planting grass stalks and turf, a pitch of 10 to 4 is set on a lawn formation ground composed of a sand base.
Using a rake having 0 cm and a nail length of 10 to 20 cm, a gap is formed between the rake nails using a groove having a depth of 10 to 20 cm in a sand base. In this groove, plant turf stalks with muscles,
The soil is covered with the artificial granular culture soil described above, preferably after being pressed 2 to 3 times with a 50 to 80 kg rolling roller from the top of the soil, and then watered. When the cultivation and growth are carried out under the prescribed irrigation and the like, germination and rooting are formed earlier and a vibrant lawn is formed as compared with the sowing lawn method. Such rapid growth of the lawn is due to the use of the above-mentioned artificial granular culture soil for the covering soil in combination with the planting of the turf broom and the turf. Even when the forked stem is planted and turfed, the artificial granulated culture soil is grown to the same coverage as when not using the artificial granular cultured soil as cover soil, or when the forked stem is sown and used as the artificial granular cultured soil as covered soil. For this purpose, it is necessary to use an extremely large amount of forked stems, for example, 300 to 400 g / m ² .

Next, an example of the production of a granular culture soil and an example of turfgrass growth will be described.

[Production example of granular culture soil] A volcanic ash soil adjusted to a water content of about 33% was dried and sterilized with hot air to obtain a raw material soil. 0.3 kg of nitrate per 1 ton of soil, chemical fertilizer (nitrogen 11%)
7 kg, 1.1 kg of superphosphate (SP 20%), 1.8 kg of potassium sulfate (50% of potassium) and 40 kg of humus are added, and 6.0 kg of slaked lime for pH adjustment is further added. At the same time, the mixture was uniformly mixed to obtain a soil mixture, which was sent to a rotary cylindrical granulator equipped with a stirrer, and granulated by adding about 1% aqueous polyvinyl alcohol solution. The obtained granular soil contains 0.035% of ammonia nitrogen (about 90% of the total nitrogen) as an active ingredient and 9% of soluble phosphorus.
Including 9mg / 100g, water-soluble potassium 0.07%,
The pH was adjusted to 6.3, and the particle size distribution was determined according to JIS K006.
As a result of measurement by a dry sieving method according to 7-2.1, the ratio of 0.2 to 1.4 mm was 90% or more.

[0013]

[Example of turf cultivation] Nine blocks of sand base were prepared on a turf ground with 40 m ² of washing ground and a 20 cm thick layer of sand. Using two types of rakes with a nail length of 15 cm and a nail spacing of 15 cm and 30 cm on this sand base, grooves of 15 cm spacing are provided in six sections of the sand base and 30 cm spacing in the other three sections. The groove was created. In the groove, as shown in the following Table 1, "Tifton 419" as the turf species (manufactured Shibazo Sangyo Co.), the turf stolons were planted muscle with 75 g / m ² and 150 g / m ^2, and covered with soil 70kg from the top of the soil
After applying three rotations with a pressure roller, predetermined growth management such as irrigation was performed to create a lawn. For the cover soil, 1 kg / m of the artificial granular culture soil produced in the above production example as a turf formation accelerator was used.
² the total 2 kg / m ² of sand 1 kg, or using artificial granular culture soil 2 kg / m ^2. In addition, 2 kg of washing sand for comparison
/ M. During the growing period, a fertilizer (nitrogen: phosphoric acid: potassium = 8: 8: 8) was sprayed once every two weeks at 50 g / m ² , and watering was performed at 3 liters / m ² daily.

Forty-five days after turf planting, the lawn coverage was examined. The lawn coverage was determined by taking a photograph of the lawn surface, projecting the photograph on graph paper, measuring the coverage area, and displaying the percentage as a percentage of the total area. Table 1 shows the results. The standard planting lawn method has a spacing of 15 cm, a lawn amount of 150 g / m ² , and sand as a soil cover of 2 kg / m ² , and the coverage after 45 days is about 40%. According to the present invention using the above-mentioned artificial granular culture soil in place of sand, the interval is 15 cm, and the amount of turf is 75 g / m ^2.
And the coverage is up to 70%, and the interval is 30c
m, the coverage is up to 60%,
It can be understood that not only the amount of lawn used for the planted turf is reduced, but also the speed and the number of stems extending and connecting between the planted turf muscles can be formed in a short period of time.
