JPH0738891B2 - Golf course green with underground oxygen blowing mechanism - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a golf course green capable of maintaining the growth of turfgrass in a good condition by supplementing oxygen from the ground.

(Prior art and its problems) The green on a golf course causes severe soil consolidation due to the heavy trampling by many people, which causes the rhizosphere part of the grass to become oxygen deficient and the grass to die due to root rot. Is occurring.

Conventionally, in order to alleviate this type of soil consolidation, oxygen is replenished from the soil surface by making the bed soil composition as sandy as possible or by mechanically drilling the pores in the soil. Nevertheless, when used for a certain period of time, solidification progresses, the pores are reduced due to the accumulation of turfgrass residue, oxygen deficiency occurs, the lawn exhibits root rot symptoms, and the vegetation density decreases,
As a result, there was a problem that the quality of putting green became extremely low due to the bare land.

(Means for Solving Problems) In the golf course green of the present invention, the underground soil structure of lawn vegetation has a pore structure, and an oxygen supply pipe is buried in the porous structure layer, and soil is supplied from the oxygen supply pipe. It is characterized in that it can be supplemented with oxygen.

INDUSTRIAL APPLICABILITY The present invention reduces the soil solidification due to a heavy trampling pressure by making the underground structure of the golf course green into a very porous structure, and the oxygen blown out from the oxygen supply pipe having a large number of fine pores buried underground in the pipe. By supplementing oxygen deficiency in the rhizosphere of the turfgrass, normal growth of turfgrass can be promoted without causing root rot symptoms even in a humid season, and good putting quality can be maintained.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a schematic cross-sectional view for explaining the green porous structure of the underground of the present invention.

As shown in the figure, set the lower surface of about 60 cm from the surface of the completed green as the surface of the base soil 1, and incline toward the drain with a gradient of 1 to 3%. 1 surface of this foundation soil is impermeable to 2
As the method, it is preferable to lay a sheet such as a plastic sheet or simply press the surface to form a hard impermeable surface.

Next, an aggregate having a thickness of about 10 cm, for example, a diameter of about 30 mm, such as pumice and crushed stone, is spread on the upper surface of the base soil 1 to be a part (lower layer) of the drainage layer 3.

A wire mesh 4 woven at intervals of 20 to 30 cm is laid on the upper part of the wire mesh 4 and used as a fixing material for the oxygen supply pipe 5. Oxygen supply pipe 5
Although not particularly limited, preferably, for example, a micropole tube having a diameter of 10 to 20 mm having a large number of fine pores of 50 microns or less in the tube body is used and fixed to the wire mesh 4 and an appropriate gap at an interval of 20 to 30 cm.

Further, the same aggregate as the drainage layer is laid on the wire mesh 4 and the oxygen supply pipe 5, and the drainage layer 3 is combined with the above drainage layer.

On the upper surface of the drainage layer 3, openings 1 to 1 are provided for the purpose of preventing clogging.
A net layer 6 is provided by laying a 4 mm net or fibrous material. The top of the net layer 6 is 20 cm thick and has a lot of pores 3-15 mm
The gravel of the diameter is spread and the B layer 7 for holding the grass grass zone and the hole cup is formed. The upper part of the B layer 7 is an A layer 8 composed of turfgrass 9 and soil so that it has a thickness of 4 to 5 cm, and the water permeation rate can be kept at 500 to 1000 mm / hr or more.

As described above, the intergranular pores are abundant in the cross-sectional structure, and oxygen is well supplied from the underground to reach the A and B layers. Therefore, it is possible to supplement the oxygen deficiency during high humidity.

As an oxygen supply source system, each oxygen supply pipe may be taken out at several places and oxygen may be supplied by an oxygen cylinder, a blower, a compressor or the like. However, it goes without saying that air may be sent instead of oxygen gas.

In the present invention, basically, a lower layer of planting soil in which turfgrass is planted is a porous layer, and this porous layer also serves as a drainage layer and an oxygen supply layer, and an oxygen supply pipe is arranged in this porous layer. Is. Therefore, the net layer and the B layer used in the above embodiments may be omitted if necessary.
Further, in forming the B layer and the drainage layer, not only the above-mentioned gravel, pumice, crushed stone, etc., but charcoal, foamed plastic, etc. may be mixed if necessary. Further, a lath metal or a plastic net may be used instead of the wire mesh 4 for fixing the oxygen supply pipe.

(Effects of the Invention) The golf green of the present invention has the construction structure as described above, and since the underground has a porous structure, excess water is often discharged, and gas such as carbon dioxide, which is harmful to the underground root system, is generated. Since oxygen is supplied instead, turfgrass grows well without root rot, and good putting quality can be maintained.
