Today, grasses that are widely used today are monocotyledonous plants, which belong to the family of plants and crops, and have about 7,500 species. Of these, about 40 species are currently used for lawns. Among them, it is said that it is suitable for the grassland, the park, the stadium, the slope, the greenery and the grassland of the landscape, such as the grassy, the golden sandy, the Kentucky blue glass, the creeping bandglass and the bentgrass. Especially, turf grass is strongest in regeneration power, strong against the pressure, has few pests, and can withstand pollution, and is widely used in Korea. Generally, grass is widely used for preventing soil erosion and providing an aesthetic environment, and its cultivation method uses a method of directly sowing on the ground.

Drainage and ventilation are vital for soil cultivated with grass. To ensure such drainage and ventilation, artificial drainage pipes must be filled or sand and gravel must be filled to increase drainage. Turfgrass (turfgrass) of turfgrass (turfgrass) caused turf growth on soil such as soil, loess soil, marathon soil, and tidal flat soil, which are not smooth water drainage, In the present invention, in order to improve this, a method of increasing the drainage property by putting several tens to several hundreds of holes in the soil where the grass grows so that the drainage is easy to the underground,

According to the present invention, it is possible to increase the drainage property by filling a hole in a pit for cultivating turf grass to fill a hole with a material easy to drain, thereby preventing root rot in grass and enhancing growth, so that the perforation and draining of the present invention can be facilitated The grass cultivation method using one substance can be used industrially.

In order to achieve the object of the present invention,

In the grass cultivation method,

(a) pouring 30 to 300 holes per square meter into the soil in which the grass is growing, to a depth of 1 to 20 cm; And

(b) filling the hole of the step (a) with a substance which is easy to drain.

In one embodiment of the present invention, the hole of step (a) may have a diameter of 5 to 50 mm, but is not limited thereto.

In addition, the number of holes per square meter may be preferably 50 to 150, more preferably 90 to 110, and most preferably 100, but is not limited thereto.

Further, the depth of the hole may be preferably 1 to 5 cm, more preferably 1 to 3 cm, and most preferably 2 cm, but is not limited thereto.

In one embodiment of the present invention, the material of which the drainage is easy in the step (b) is sand: peat moss: coco peat: chaff: sawdust 75-85: 3-7: 3-7: 3-7: The mixture may be a mixture of water and an organic solvent in a weight ratio of 3 to 7, preferably 75 to 85: 4 to 6: 4 to 6: 4 to 6: 4 to 6, and most preferably 80: : 5: 5: 5, but is not limited thereto.

Peat moss is a kind of peat moss that has been partially carbonized (aged and corroded) without being completely decayed at low temperatures due to air being blocked in wetlands, swamps and watery soil for a long time. Natural nitrogen, phosphoric acid, potassium And it has high CEC by humic acid component. When it is sprayed on the soil, it is good in water dripping (drainage), and it is easy to breed microbes because it is good in ventilation, .

Cocopeat is a by-product of extraction of coconut fiber from coconut shells. It has similar properties to sawdust, which is used as a moisture regulator in compost production. However, water absorption rate is more than three times that of sawdust per unit volume, It is a material with optimal conditions as a moisture control agent at 0.5 times.

The rice husk is the most easily available organic material in Korea and is estimated to produce over one million tons per year. The rice husk has a high specific gravity (100kg / ㎥) and high transportation cost. It has high lignin and silicate content, which makes it difficult to process. However, it has a high decomposition stability and its absorption rate is low compared to peatmoss, It is a material with very good breathability.

The grass of the present invention may be, but not limited to, turf grass such as Korean grass, Bermuda grass, Bahia grass, Buffalo grass, Zenith and the like.

In addition, the present invention provides a herbarium with improved drainage ability grown by the above method. According to the cultivation method of the present invention, the grass grown on the hearth can be sold in the form of a grass flock by peeling off the soil together with the hole containing the material which is easy to drain.

Hereinafter, the present invention will be described in detail by way of examples. However, the following examples are illustrative of the present invention, and the present invention is not limited to the following examples.

Example  1. Analysis of drainage and survival according to the number and depth of holes

Table 1 shows the results of measuring the permeability coefficient according to the number of holes and the depth after pouring holes having a diameter of 10 mm in the soil (soil) where Korean lawns are cultivated as shown in Table 1 below. The higher the number of holes, the deeper the depth of the hole, the larger the permeability coefficient of the soil than the control soil without holes.

Permeability coefficient (mm / h)

Number of holes (/ m ² ) Control
(No holes) 50 100 500 Hole depth
(cm) 2 790 900 1100
760
5 810 1050 1300 10 840 1300 1600

In addition, as shown in Table 2 below, after 100 holes were laid out in the grass cultivation soil at various depths, after 3 months, the survival rate of grass according to presence or absence of holes was compared and analyzed. As a result, it was confirmed that the survival rate of grass cultivated in the perforated section was good as shown in Table 2 below.

Survival rate (%) Control (no holes) 34 Treatment (100 holes, 2 cm deep) 84 Treatment (100 holes, 5 cm deep) 81 Treatment (100 holes, 10 cm deep) 79

Example  2. Comparison of drainage and survival rate according to composition ratio of mixture

Sand, peat moss, coco peat, rice husk and sawdust, which are frequently used as the material of the soil, were mixed at various weight ratios as shown in Table 3 below, filled in the holes, and the same experiment was conducted. The holes gave 100 per square meter for each treatment.

Permeability coefficient (mm / h) 2cm 5cm 10cm Control (no holes + no mixture) 750 80% of sand + peatmoss 20% 950 980 1100 Sand 80% + peatmoss 7% + coco peat 7% + chaff 3% + sawdust 3% 1030 1050 1140 Sand 80% + peatmoss 5% + coco peat 5% + rice hull 5% + sawdust 5% 1100 1140 1200 Survival rate (%) Control (no holes + no mixture) 35 80% of sand + peatmoss 20% 74 71 68 Sand 80% + peatmoss 7% + coco peat 7% + chaff 3% + sawdust 3% 82 79 77 Sand 80% + peatmoss 5% + coco peat 5% + rice hull 5% + sawdust 5% 94 90 87

As a result, the mixture of sand, peat moss, coco peat, rice hull and sawdust was better than sand and peat moss mixture. Sand: Peat moss: coco peat: rice husk: Sawdust composition ratio 80%: 5 %: 5%: 5%: 5%.

The survival rate of lawns was higher than that of 5cm and 10cm, and the survival rate of sand, peat moss, coco peat, rice husk and sawdust was higher than that of sand and peat moss alone , Especially sand: peat moss: coco peat: rice husk: sawtooth composition ratio is 80%: 5%: 5%: 5%: 5%.
