Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to greens in golf courses.

[Prior Art] Many of the greens at golf courses are so-called sand greens, in which the green floor is formed of sand and grass is spread over the green.

The reason why the green bed is made of sand is expected to have better drainage compared to soil, and after the grass is planted, water and fertilizer are sprinkled from above the green, that is, from the surface of the grass, to provide nutrients. In addition, pesticides are also sprayed on the lawn to prevent the growth of pests and weeds.

In particular, regarding the above-mentioned water spray, water is sprayed from a water nozzle at the end of a hose, or a sprinkler is installed near the green so that the water sprayed from the sprinkler can reach the green.

[Problem to be solved by the invention]

However, when watering sand greens from the second position, much of the water flows from the green surface to the outside of the green via the green edges without reaching the inside of the sand bed. In anticipation of the amount that will flow away without penetrating, you must sprinkle as much water as possible.

On the other hand, if too much water is applied, including during heavy rainfall, or if snowfall continues for a long time in a cold region, water may accumulate in the sand bed and cause the grass to become cluttered. .

The purpose of the present invention is to eliminate the disadvantages of the conventional example, to provide the appropriate amount of water and nutrients to the grass without wasting it, and as a result,
The purpose is to provide a golf course green that can achieve healthy grass growth management at low cost and with a high degree of reliability.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention introduces a water distribution pipe under the green floor, and installs a porous rubber or resin made water pipe at the end of which the liquid is leached from the inside under low water pressure. The main points are that the water pipes were extended, the drain layer was formed by dividing the lower part of the sand bed with multi-tube aggregates like honeycomb pots, and the water pipes were further placed under the train layer. It is something.

[Effect]

According to the present invention as set forth in claim 1, water is introduced directly under the green floor through the water distribution pipe without being sprinkled from above, and furthermore, water is introduced directly under the green floor from the inside of the porous sprinkler pipe extending into the water distribution pipe. Since it is leached using water pressure, water is effectively added to the green bed little by little without wasting it, keeping the soil moisture content at an appropriate level, and as a result, the grass can be grown effectively.

The same applies to the case where nutrient water or agricultural chemicals containing minerals are given instead of water using the water distribution pipe and the sprinkler pipe.

Furthermore, by connecting a blower to a water distribution pipe and using these water distribution pipes and sprinkler pipes as an air supply pipe to supply air to the green floor, it is possible to provide oxygen and the like and to activate nutrients in the soil.

According to the invention as set forth in claim 2, in addition to the above-mentioned effect, the drain layer effectively transfers water seeping from the sprinkler pipe toward the root zone of the grass.

In addition, because of this drain layer, there is less fertilizer runoff due to rainwater, etc. compared to Sand Green, which has only a sand bed, and high fertilizer retention capacity is maintained, as well as constant drainage even in heavy rain, and it is less prone to soiling due to snow in cold regions. It also has the effect of preventing curls.

C Example] Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a vertical side view showing one embodiment of a green in a golf course according to the present invention, and FIG. 2 is a partially omitted perspective view of the green, in which a sand bed 2 made of sand 2a is placed under the grass 1 on the surface. The deepest part is the foundation made of crushed stone 3, and in this crushed stone 3 there are about 10
A blind culvert water collection pipe 4 with a diameter of about 0 φ will be buried. This water collecting pipe 4 may have a pipe wall with a large number of small holes, or a pipe wall of a mesh type.

The structure is the same as that of the conventional sand green, but the layer of sand 2a forming the sand bed 2 of the present invention is about 300 mm deep, and at about 200 mm from -L, A multitube assembly 5 in which tubes 5a such as honeycomb pots were arranged in series was buried, and a train N6 partitioned by the tubes 5a was formed to have a length of about 50 to 100 I [1 m].

Furthermore, although a honeycomb pot was used in this example, if it is a multi-tubular aggregate that can be filled with sand or
The shape is not limited to a honeycomb, and it is also possible to use a lattice-shaped bot that is a collection of rectangular tubes, a scale-shaped bot that is a collection of triangular tubes, and the like.

The multi-tubular assembly 5 may be made of paper such as cardboard, but is preferably made of synthetic resin such as vinyl chloride sheet in view of the fact that it is easily perishable.

Further, the material to be filled in the multi-tubular aggregate 5 may be the sand 2a forming the sand bed 2, but it may also be a special sand 7 mixed with ceramic (theotolite), carbon, or the like.

Furthermore, in this multi-tubular aggregate 5, each part 5a of the (honeycomb) bot is filled with the special sand 7 mixed with ceramic (heptaodolite), carbon, etc. to form a sand column, and the adjacent The cylinder 5a has an organic aggregate structure.
A soil column may be formed by filling the soil improving material with culture medium ±8.

This soil 8 is made by mixing cow dung, inorganic red clay, theodolite, etc. as raw materials using a unique method, and then injecting a liquid created by a combination of water and magnetism induced by an ultra-trace amount of divalent and trivalent iron salt. Zeta-fermented products are suitable.

The sand pillars made of the special sand 7 and the soil pillars made of the soil 8 may be arranged in rows or alternately in relation to the tube 5a, and their arrangement is particularly limited. Not limited.

In the present invention, under the train layer 6, a porous rubber J,
A sprinkler pipe 9 made of aluminum or resin is installed, and a layer 10 of a residual pesticide removal material using charcoal or the like is formed below it, and the layer 10 below it is made of crushed stone 3 according to 111.

As shown in Fig. 3, a water distribution main pipe 12 made of vinyl chloride or the like is installed in the sand bed 2 of the green 11, with a valve 13 in the middle for water reduction and positive water, and is laid toward the center of the green 11. A branch pipe 12a is branched off from the main water distribution pipe 12, and the porous rubber or resin sprinkler pipe 9 is connected to the branch pipe 12a so as to extend.

This porous water sprinkler pipe 9 is a sponge-like flexible pipe having micropores made of foamed rubber or foamed synthetic resin, and its tip is closed.

In addition, to further describe the layer 10 of the pesticide residue removal material described in 1iii, charcoal 141 powder is packed, and this charcoal powder is also combined with water and magnetism induced by an ultra-trace amount of divalent and trivalent iron salt. It has been specially treated with liquid.

Furthermore, instead of coarse charcoal powder, ceramic balls and shell stones can also be used after being specially treated with a liquid by combining water and magnetic silk induced by ultra-trace amounts of divalent and trivalent iron salts. .

In this way, the water distribution main 12 is connected to the water supply source, and the water to be sent to the sprinkler pipe 9 is adjusted to a water pressure of about 0.1 to 2 kilograms per square centimeter (torre) at the valve ↑13. Also, up to 40 millimeters per minute per tool
If the flow rate is approximately 1.5 mm, the water will gradually flow out from the inside of the sprinkler pipe 9 to the outside.

The seeped water is sucked upward by the drain layer 6 and is effectively sent to the root group area of the grass l through the sand bed 2, thereby maintaining the soil moisture content at an appropriate level.

In detail, watering from the bottom in 51 patterns according to the water content of the soil causes the grass roots to develop twice as much due to capillary action compared to normal surface watering, making them more resistant and resistant to damage. It is what it is.

The above is a case of watering lawn 1, but this water distribution main 1
2. The branch pipe 12a and the water sprinkler pipe 9 may be used to supply nutrients or agricultural chemicals instead of water.

Grass plants include grasshoppers, orifolia, and tiftonsiha, and in addition to the native grasshopper, there are also grass moths, which are said to have invaded 11 grasses with the importation of tiftonshiha, and turfgrass pests. The larvae damage the turf grass and lay eggs, and the larvae initially feed on the turf stalks, but eventually grow underground.
It burrows down to around 6cm and eats the roots.

Regarding pesticides, instead of spraying them from above the green 11 as in the past, by allowing them to seep out from the sprinkler pipe 9 with low water pressure, it is possible to sterilize the soil and inject pesticides without wasting the soil. In addition to effectively killing insects that burrow inside, providing the minimum number of stars will contribute to reducing the use of pesticides at the Sumi Golf Course.

Then, the remaining pesticide passes through the layer 10 of the residual pesticide removal material and flows into the water collection pipe 4, but the layer 10 of the residual pesticide removal material has the effect of the charcoal coarse powder itself purifying the water, and the ultra-trace amount Because it is treated with a liquid that uses a combination of water and magnetism induced by divalent and trivalent iron salts, it has the effect of purifying the water even more, and the pesticides contained in it are removed and the water is collected in the water collection pipe 4.
The water enters the water and flows into ponds and other places built in the adjustment area.

On the other hand, it is also possible to connect a blower to the water distribution pipe 12 and use these water distribution main pipe 12, branch pipe 12a, and water sprinkler pipe 9 as an air supply pipe to supply oxygen and the like to activate nutrients in the soil.

FIG. 4 shows a second embodiment of the present invention, in which a water main pipe 1
2 is laid toward the center of the green 11, and a branch pipe 12a is branched from this water main pipe 12, which is the same as in the first embodiment, but a water sprinkler pipe 91 connected to this branch pipe 12a is
, 1 meandering, and a spiral arrangement.

Further, as shown in FIG. 3, a water distribution main pipe 12, a branch pipe 12a, and a water sprinkler pipe 9 can also be provided not only on the green IJ but also on the fairway 14 and used in the same way as the green 11.

It should be noted that fertilizers and pesticides are not sprinkled over Green 11.

In this case, since there is a drain layer 6, there is less fertilizer runoff due to rainwater etc. compared to sand green with only a sand bed.
It maintains a high fertilizer retention capacity, provides constant drainage even in heavy rain, and has the effect of preventing roots from being eroded by snow in cold regions.

[Effects of the Invention] As described above, in the golf course green of the present invention, water, etc. is introduced directly under the green floor without being sprinkled from above, and furthermore, it is leached with low water pressure, so there is no waste. The present invention effectively applies water to the green bed little by little and maintains the soil moisture content at an appropriate level, and as a result, it is possible to manage the healthy growth of turf at low cost and with a high degree of reliability.

In addition, since the minimum necessary amount of pesticides can be applied directly to the ground, it can contribute to reducing the amount of pesticides used.
