Description
Technical field
The present invention relates to sports equipment, more particularly to a kind of green structure.
Background technology
Golf originates from ancient Scotland, is passed to behind the U.S. and pushes the world to by American.Golf course includes
Greens, service platform, alley, rough, Landscape Region, original place looks reserved area, waters etc., wherein core of the greens as golf course
Center portion position is the lawn where match play.Turfgrass in greens mainly absorbs water by root system to the absorption of moisture from soil
Point, it is conveyed to top using tissue is dredged, meets the needs of vital movement.The water absorbing capacity of turfgrass is decided by its root system
Effective water content in vigor and soil.
Turfgrass water shortage rear blade occur withering here symptom, turf color becomes blue-green or celadon, follows the string, in grass
Dry spot is commonly known as by the region for being different from normal turf color that these water shortages are formed in the maintenance of level ground（Dry spot or Dry
patch）, solve the most direct mode of dry spot be exactly moisture is replenished in time, but be replenished in time sometimes moisture also can not solution decided
Existing lawn dry spot, the reason is that caused by soil particle hydrophobicity in lawn soil, this partially hydrophobic soil particle
Can not be affine with moisture, that is, soil is unable to sticking moisture, water retention property is poor, to make lawn plant root system that can not also absorb
Moisture, it is not related with irrigation volume.When occurring dry spot in greens, the grass in dry spot region has followed the string, with having for surrounding
The grass of elasticity asks ball to be different compared to it, and such player is difficult to grasp in dynamics, certainly will influence its achievement.
Invention content
The object of the present invention is to provide a kind of green structure, have the effect of improving water retention property.
The present invention above-mentioned technical purpose technical scheme is that：A kind of green structure,
Include successively from top to bottom greens mixture layer, metalling, ground, further includes the high score being set in the greens mixture layer
Sub- gel layer, through the aqueduct of the Macromolecule glue-line, the aqueduct upper end tube nozzle is higher than the Macromolecule glue-line
And lower end nozzle is less than the Macromolecule glue-line.
By using above-mentioned technical proposal, high-molecular gel is a kind of cross-linked network of three-dimensional, can be occurred when absorbing moisture
Swelling, water enter in cross-linked network structure, lead to the derivative of three-dimensional molecular network.High-molecular gel is located at greens mixture layer
It is interior, when being poured to green structure, high-molecular gel layer is touched after moisture infiltration downwards, by high-molecular gel
After high-molecular gel in layer absorbs, extend to upper and lower after high-molecular gel swelling, and coat the soil in greens mixture layer
Particle is coated on after the hydrophobic soil particle in greens mixture layer is coated by high-molecular gel on hydrophobic soil particle
High-molecular gel can absorb moisture, improve the water retention property of hydrophobic soil particle.Grass planting on greens mixture layer,
After the root system of grass grows up and touches Macromolecule glue-line, the moisture in Macromolecule glue-line can be directly absorbed.
Macromolecule glue-line is arranged in greens mixture layer, after Macromolecule glue-line water absorption and swelling, greens mixture
Interior moisture is not easy to be passed down through Macromolecule glue-line, and Macromolecule glue-line can also play blocking moisture and continue infiltration downwards, will
Portion of water is accumulated in greens mixture layer, and when accumulation moisture is more in greens mixture layer, moisture can be by leading
Water pipe moves downward, and by the subsequent continuous infiltration downwards of Macromolecule glue-line, can accumulate and holding part moisture and arrange in time
Water has achieved the effect that improve water-retaining property, has avoided lawn dry spot.
The further setting of the present invention is：It is provided in the greens mixture layer above the Macromolecule glue-line
Irrigation pipeline, the liquid reserve tank being communicated on the irrigation pipeline above the irrigation pipeline.
Irrigation liquid is poured into liquid reserve tank, irrigation liquid is along irrigation pipe by using above-mentioned technical proposal when needing to irrigate
