Description

Description: FIELD OF THE INVENTION The present invention relates to a method of growing turfgrass, and more particularly, to laying a pattern paper cut out of a desired shape on rockwool or wood pulp spread in a box, and cutting the turfgrass in the cutout portion. This is a method of shaping and growing turfgrass into a desired shape by sowing seeds.

BACKGROUND ART Conventionally, turfgrass is used to grow a turfgrass by cultivating a flat field, cultivating, fertilizing, sown in a leveled place, and transplanting the turfgrass sod cut into a square to be spread over a predetermined ground. Is common. As another method, there is also known a method in which turfgrass sods are grown in a nursery box for paddy rice seedlings using mountain soil or granular soil as floor soil. However, any method is used as a square turf grass sod, and there has been no proposal to grow turf grass in an arbitrary shape.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method suitable for growing turfgrass on, for example, a veranda of a high-rise house, and for growing turfgrass in an arbitrary and desired shape.

Means for Solving the Problems The present invention is to place a paper cut out of a desired shape on rock wool or wood pulp laid in a box, and pH 6 to
7 and the turfgrass seeds and water are added to and mixed with the granular cultivation granulated to have a particle size of 1 to 4 mm, and the seeds are sown in the cut-out portion of the pattern, and then the granular cultivation is covered with soil. It is a method of shaping and growing turfgrass.

 Hereinafter, the present invention will be described in detail.

The granular soil used in the present invention is obtained by granulating soil, which has been adjusted to pH 6 to 7 in advance, to a particle size of 1 to 4 mm. Desirably, 0.01 to 2% by weight of a chemical fertilizer is contained as a fertilizer component.
More specifically, nitrate nitrogen 0.002-0.006% by weight, ammonia nitrogen 0.03-0.04% by weight, total phosphorus about 0.2% by weight,
Water-soluble potassium 0.04 to 0.08% by weight and citrate magnesium
Those containing at least 02% by weight are preferred. By adding fertilizer to the granular soil as described above, fertilization is not required about one month after sowing, and labor is saved. Soil is pH6 ~ before granulation
Adjust to 7. Such a pH range is suitable for the germination and growth of turfgrass, and those whose pH is adjusted to 4.5 to 5.5, such as granular soil used for growing rice seedlings, are not preferable for the growth of turfgrass. If the pH of the granular soil is out of the above range, the growth is impaired, which is not preferable.

The grain size of the granular soil is suitably 1 to 4 mm. If it is smaller than 1 mm or larger than 4 mm, it is not preferable because it is classified and tends to cause uneven seeding.

Rock wool used as a substitute for the floor soil is obtained by molding mineral fibers mainly composed of silicic acid into a mat shape, and wood pulp is also used in a mat shape. Since rock wool or wood pulp is produced industrially, unlike soil, it does not contain pathogens or weed seeds, is lightweight and easy to handle, has good ventilation and air permeability, and has no difference in turfgrass growth. Can be grown in any way. Further, rock wool or wood pulp acts as a material even when the granular soil used as the covering soil collapses, has an advantage of not discharging muddy water, and is convenient for growing on a veranda of a high-rise house.

Rock wool or wood pulp is spread in advance in a box to a thickness of 1 to 5 cm, preferably 2 to 3 cm, and a pattern paper having an arbitrary and desired shape cut out is placed thereon. Seeds are added to the granular soil together with water, uniformly mixed and sown. Turfgrass seeds and granular soil,
The sound ratio of water is 1 g of turfgrass seed, 40-60 g of granular soil, 6-1 water
It is preferable to mix the mixture to 0 g. If the ratio is out of this range, uniform sowing becomes difficult. That is, by mixing the turfgrass seed, the granular soil and the water in the above-described ratio, the seed and the granular soil are mixed with each other to make it difficult to classify, and a mixture having fluidity suitable for sowing is obtained.

 Hereinafter, specific examples will be described.

Example 1 A box having a drainage hole at the bottom (inner method: 172 cm x 72 cm x 5 cm)
2cm thick rock wool is spread over it, and a drawing paper cut out from the shape shown in Fig. 1 is placed on it, and 10 g of pentgrass seeds, 500 g of granular soil, and 80 g of water are placed on the cut out portion in advance.
Seeded with a uniform mixture of
Covered to a thickness of m and placed on a veranda facing south.

In addition, the granular soil used was a nitrate nitrogen 0.00 as a fertilizer component.
6% by weight, ammonia nitrogen 0.032% by weight, total phosphorus 0.211% by weight, fusible magnesium 0.02% by weight, water soluble potassium 0.06
8% by weight of soil adjusted to pH 6.5
It is granulated.

Germination showed uniform germination in the shape of difficult paper to about 1 mm on the fourth day after seeding in the climate of August. Water was irrigated once a day after germination. FIG. 2 shows the condition of the turfgrass 15 days after sowing.

Example 2 A wood pulp was used instead of the rock wool of Example 1,
Turfgrass was grown in the same manner as in Example 1 except that the pattern shown in FIG. 3 was used instead of the pattern shown in the figure. FIG. 4 shows the state of the turfgrass 20 days after sowing.

Comparative Example When turfgrass was grown in the same manner as in Example 1 using mountain soil instead of the rock wool of Example 1, germination occurred on the 6th day after sowing, but there was uneven germination. It did not come out as beautiful as shown.

[Brief description of the drawings]

FIG. 1 is a pattern used in Example 1, FIG. 2 is a photograph showing the state of turfgrass grown in Example 1, FIG. 3 is a pattern used in Example 2, and FIG. 9 is a photograph showing the condition of turfgrass grown in Example 2. In FIGS. 1 and 3, hatched portions are cut out.
