Abstract

PROBLEM TO BE SOLVED: To harvest a high quality rush without affected by weather and climate conditions in the cultivation of a rush which favors a warm and humid climate. SOLUTION: After management works such as the removal of weeds and the application of additional fertilization following the transplantation of seedlings of rushes are completed, a light screening means for reducing the direct sunlight by half is applied over the rush with a specified space from the top of the rush. This can prevent the withering of the top of a grown rush, and at the same time in the case where the growth is not enough, the growth is accelerated because an appropriate humidity is kept and the lowering of temperature at night is prevented by the light screening means. Thus, a high quality rush can be harvested.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating rush, which is used by braiding as a mat and a tatami mat.

[0002] Generally, rush is a warm and humid plant, and after the rush seedling is planted, management work such as weed removal and top-dressing is performed between early spring and the rainy season. It is harvested around the end of the month.

However, depending on the year, the rainy season may be short or the sky may be rainy, and even in normal years it is 7
When the rainy season opens in the beginning of the month, the midsummer sun shines on and the grass is exposed to direct sunlight. Even if the period of receiving this direct light is, for example, about three weeks, the tip of the grass will die due to the strong sunlight, let alone the period of rainy season is short or the sky is rainy. However, it has a problem that the quality of rush is deteriorated due to insufficient growth.

Therefore, in the conventional cultivation, there is a problem that must be solved to achieve sufficient growth without degrading the quality.

[0005]

Means for Solving the Problems As a concrete means for solving the problems of the conventional example, the present invention provides a predetermined method from the tip of the rush after finishing the management work such as weed removal and additional fertilization after rush planting. The present invention provides a method for cultivating rush, characterized in that a light-shielding means for halving direct sunlight is provided at intervals of, and the light-shielding means includes a net material or a curtain member.

By providing a light-shielding means for halving direct sunlight at a predetermined distance from the tip of the grass, for example, even if the rainy season is short or the sky is rainy, the inside covered by the light-shielding means grows. Since the necessary moisture remains and the intense direct light is halved, it is possible to grow rushes that prefer warm and high humidity and to harvest good quality rushes without dying the tips.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings. 1 is rush, which is planted and grown in a predetermined paddy field. The light-shielding means 2 is arranged on the upper part of the moderately grown grass with a predetermined interval.

The main purpose of the light-shielding means 2 is to halve the direct sunlight of strong sun rays.
The inside covered with the light shielding means 2 serves to lower the temperature in the daytime and to keep the temperature in the nighttime. The material to be used is, for example, a net material, a thin curtain member, or a screen, and is arranged via the predetermined support column 3 and the string material 4.

When a net material is used as the light-shielding means 2, a material having a small mesh size knitted with a black thread is used. When the mesh size cannot be reduced as planned, a plurality of layers are stacked. It should be used.

[0010] In general, the rush 1 is subjected to management work such as weed removal work and fertilization work from the beginning of spring after planting seedlings to the rainy season, and when the rainy season is normal and there is little sunshine. Therefore, it is not always necessary to provide the light-shielding means 2 during the rainy season because it can grow smoothly, and the light-shielding means 2 is provided in order to avoid direct sunlight after the rainy season.

If the rainy season is short or the amount of rainfall is extremely small, the light shielding means 2 is provided earlier. In other words, since the grass 1 prefers warm and high humidity, the entire grass 1 is covered with the light-shielding means 2 provided so as to protect it from the weather of carrara, and the covered interior holds a suitable amount of moisture. It also prevents the temperature from dropping at night and assists the growth of grass 1.

When the growth of the rush 1 is delayed due to weather conditions such as the rainy season, the light-shielding means 2 is arranged as close to the rush 1 as possible and is shielded as the grass 1 grows. It is better to sequentially lift the means 2, and
For the purpose of halving the direct sunlight, it is better to dispose the grass 1 at a relatively wide distance from the upper part thereof.

In any case, the shading means 2 is provided on the upper part of the grass 1 at an appropriate interval at an appropriate time after the management work such as the weed removal work and the fertilization work is completed, while considering the weather and weather conditions. When the growth of the grass 1 is slow, the growth is supported by the retention of moisture and heat retention, and the intense direct light such as the sun in the midsummer is halved to the tip. It is possible to harvest good quality grass in any case.

Therefore, the time for disposing the light-shielding means 2 is after the completion of management work such as weed removal work and fertilization work, for example, before the rainy season in consideration of the growth of rush and weather conditions. However, if necessary, the light shielding means 2 is provided so that the grass can be raised.

Strings for preventing the grass 1 from collapsing are stretched in a lattice pattern at a predetermined interval, or a net having a large mesh is stretched at a predetermined height in the grass. This is the same as the conventional example. Further, by disposing the light-shielding means 2, it is possible to prevent the grass 1 from being secondarily exposed to the strong wind and the heavy rain, thereby preventing the grass from collapsing and improving the quality. .

[0016]

As described above, the method for cultivating rush according to the present invention has a predetermined interval from the tip of rush, after finishing the management work such as weed removal and top-dressing after rush seedling planting, By providing the light-shielding means for halving the direct sunlight, it is possible to avoid the phenomenon of dying at the tip of the rush and to obtain high-quality rush.

Further, by providing light-shielding means for halving direct sunlight at a predetermined distance from the tip of the grass, for example, even if the rainy season is short or the sky is rainy, the inside covered by the light-shielding means. Moisture required for growth remains, and at the same time, it has the excellent effect of preventing the temperature drop at night and promoting the growth of grass that prefers warm and humid conditions.
