Furthermore, the planting soil suitable for Zoysia matrella Merr. of teeing ground and fairway is obtained by laying the pulverized small lump and/or granular bamboo charcoal 1 over the dug surface soil, laying the sand 2 thereover, forming the soil and planting the Zoysia matrella Merr. 4 in the sand 2 in the surface layer. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a soil suitable for lawn planting in a golf course green, tee ground, and fairway.

  Lawn cultivation and management operations at golf courses include irrigation, fertilization, weed removal, pest control, pathogen sterilization, etc. In order to perform these operations, chemical fertilizers, herbicides, insecticides, sterilization Chemical agents such as drugs are used. Due to the heavy use of these various chemicals, the soil is damaged and the lawn becomes stunted or the environment is destroyed.

Conventionally, as an invention for improving soil such as lawn, lawn planting soil in which a culture soil layer is formed on a pulverized coal layer and planted with lawn is disclosed in, for example, Patent Document 1 below.
JP 2004-248599 A

  The stems, leaves, and roots of turfgrass die and new stems, leaves, and roots emerge one after another, and the generations of dead scum are decomposed by soil microorganisms and returned to the soil to suppress soil consolidation. However, with the heavy use of chemical agents such as chemical fertilizers, insecticides and fungicides, if the useful soil microorganisms are reduced, the dead residue accumulates without being decomposed. In particular, the accumulated portion of the withered residue becomes hypoxic and the activity of soil microorganisms is reduced, making it difficult to decompose.

  In order to compensate for this decline in the activity of soil microorganisms, even if chemical agents can be used to temporarily control pests and diseases, chemical-dependent effects that the useful soil microorganisms are further reduced and the soil becomes unhealthy. The vicious circle cannot be broken.

  In addition, lawn soil cannot be cultivated like agricultural soil, so it is impossible to carry out aeration by cultivating.

  Therefore, the lawn planting soil of the present invention was conceived to solve the problem of lawn maintenance and management in golf courses.

  The planting soil suitable for the bent turf of the present invention is laid with crushed small lump and / or granular bamboo charcoal, on which a mixed layer of sand and pulverized granular bamboo charcoal is laid, and further sand is laid. The soil is formed, and bent turf is planted on the surface sand.

  The planting soil suitable for the ginseng turf of the present invention is laid with crushed small lump and / or granular bamboo charcoal, on which the sand is spread to form the soil, and the ginseng is planted on the surface sand. It is.

  According to the lawn planting soil of this invention, by embedding bamboo charcoal, the water retention of the soil is improved, soil microorganisms are fixed and grown in bamboo charcoal and surrounding soil, decompose organic matter and make fertilizer Therefore, it becomes possible to reduce the frequency and amount of watering, and the use of chemical fertilizer can be suppressed. In addition, the diversity and growth of soil microorganisms can suppress the growth of pathogenic bacteria, thus reducing the use of chemical agents. Therefore, it is possible to reduce the cost and labor of maintenance and management work for the lawn.

  Since the buried bamboo charcoal is hard, it does not lose its shape, and the ground surface on which the lawn is planted does not deform over a long period of time.

  Bamboo charcoal is mainly composed of carbon, so it does not change in quality even when buried in soil, and its water retention capacity, ability to decompose organic matter by attached soil microorganisms, and water purification capacity are maintained for a long period of time. Therefore, the lawn can be nurtured for a long time without changing the soil.

  Conventionally, lawn soil using charcoal has been implemented. The lawn planting soil of this invention uses bamboo charcoal. Bamboo charcoal has a higher carbonization temperature than charcoal, so it is firm and does not lose its shape. Bamboo charcoal is a porous material with a large surface area, so it has 2-5 times the water retention capacity of charcoal, and has excellent holding power to gradually release the water once retained over time. Water retention is extremely high. In addition, soil microorganisms settle and grow and decompose organic matter. Therefore, the lawn planting soil of the present invention was conceived by paying attention to such characteristics of bamboo charcoal.

  As shown in the sectional view of FIG. 1 (a), a bent turf planting soil in which the present invention is applied to green has a small lump and / or granular bamboo charcoal 1 excavated and crushed to a depth of about 25 cm. Is spread to a thickness of 3 to 5 cm, and then a mixed layer 3 in which washing sand and pulverized granular bamboo charcoal are mixed at a ratio of 8: 7 (volume ratio) is spread to a thickness of about 15 cm. The washing sand 2 mixed with is spread to a thickness of about 5. Then, the bent turf 4 is planted on the surface washing sand 2.

  As shown in the cross-sectional view of FIG. 1 (b), the planting soil of Goryeo turf applied to the tea ground of the present invention is a small lump and / or granular bamboo charcoal obtained by excavating and crushing the top soil to a depth of about 15 cm. 1 is spread to a thickness of about 5 cm, and a mixed layer 3 in which wash sand and pulverized granular bamboo charcoal are mixed in a ratio (volume ratio) of 2: 3 is spread to a thickness of about 5 cm, and a vitality agent The washing sand 2 mixed with is spread to a thickness of about 5. Then, the Korean turf 4 is planted on the washing sand 2 of the surface layer.

  As shown in the cross-sectional view of FIG. 1 (c), the planted soil of Goryeo grass applied to the fairway of the present invention is obtained by excavating the top soil to a depth of about 10 cm and crushing the granular bamboo charcoal 1 to a thickness of about 5 cm. Spread the sand on the top, and wash sand 2 mixed with vitality agent to a thickness of about 5 cm. Then, the Korean turf 4 is vegetated on the washing sand 2 on the surface.

  The vitality agent used in the embodiment described above is a growth promoter, a slow-acting fertilizer, etc., and does not necessarily need to be mixed with the washing sand 2, and if mixed, blended according to the season and environment What is necessary is just to select suitably and to mix. The thicknesses of the bamboo charcoal layer, the sand layer, the mixed layer of bamboo charcoal and sand, and the type of lawn shown in the embodiment are merely examples, and do not limit the present invention. Modifications and changes can be made without departing from the spirit of the invention.

It is sectional drawing which shows embodiment of the planting soil of the lawn of this invention.
