Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for maintaining the greening of plants such as turfgrass in the summer, particularly to a method for maintaining the lawn in the summer, and more particularly to a method for maintaining the lawn in the summer in the greened state.

[0002]

2. Description of the Related Art Golf courses, racetracks, tennis, suckers, baseball and other stadiums, natural parks, garden meadows, lawn seedlings and other green areas, or turfgrass or other roots that are well rooted on the ground surface In order to keep vegetation such as turfgrass, plants such as turfgrass all year round, plants such as turfgrass are kept in a green state to keep them growing. It is necessary to maintain and maintain the greening condition in terms of growing condition without any hindrance throughout the year, and it is very important to do so. Therefore, if it is possible to supply an appropriate amount of water under natural conditions such as rain when the temperature is extremely high, such as in summer, or if water is supplied by a sprinkler, the plant will surely grow. However, it is possible to sustain growth by supplying appropriate amounts of appropriate fertilizers and pesticides. However, in recent years, due to the promotion of sports, there is a tendency that what used to be a forest becomes a golf course, and even in the suburbs, what used to be a farmland becomes a golf course or a sports arena. On the contrary to increasing the yield while fully using pesticides and fertilizers as in the past farmland, on the contrary, if you can use pesticides and fertilizers as little as possible, you can use no pesticides and fertilizers at all. We are carrying out research related to maintaining. In addition, since the incidence of pests is particularly high during the hottest summer months of the year, it may be necessary to spray pesticides to control the pests. Therefore, research has been conducted on growing plants that are less susceptible to pests, but anyway, the application of pesticides poses a new problem because it causes water pollution and other adverse effects on domestic water. In addition, even if the lawn on the grass of sports fields such as golf courses is managed, the construction of golf courses or stadiums is usually done as a part of civil engineering work. Therefore, in the process, the construction work is recommended without the participation of experts who are bright in terms of plant cultivation such as agricultural technology or horticultural technology, and their lawn is not added in advance, and finally the lawn is planted. As the work to grow, it involves contracting or ordering multiple lawns to work on the lawn grass, and creating the lawn ground. The construction work has been done without much interest in trying to unify the varieties. Therefore, the result is that the management of turfgrass after the fact takes more time than expected, and there is no room for problems such as the uniformity of varieties. Regarding the longevity of turfgrass, it has been found that growing perennial turfgrass gives better results than growing perennial turfgrass and perennial turfgrass. The problem is that the degree of progress of growth is lower than that of, which is a drawback. In addition, even if a perennial grass is exposed to extremely low temperatures in winter, even if it is a perennial grass that should have a long life, the life will be shortened. It often happens that it is shortened more than expected. In addition, even if it is called a perennial turfgrass, the turfgrass has the property of growing new leaves, stems, and roots every year and renewing old ones, and forming new plant tissues. Thus, for hundreds of years or longer, the roots of plants, that is, trunks and large roots, grow even little by little, and they will not wither unless they are so good. In that sense, the perennial turfgrass is similar to the annual turfgrass and the perennial turfgrass in that the structural components of the plant are not particularly different, and the stems of the dashes still grow around. The characteristic of turfgrass is different from that of trees in that it spreads over a wide range, or increases in number by splitting, or when grown from seeds it becomes a mature seedling relatively quickly. Therefore, as a means to maintain the greening status of turfgrass, perennial grass that can withstand even the bad conditions between the cold winter and the hot summer in one year is good in some winters. Strong ones have weaknesses in summer or strong in summer, but have weaknesses in winter, and it is difficult to endure one year with only one kind of turfgrass. And, when it is cold in winter, it is relatively rare to play sports such as golf in those green areas, but in summer, the usage rate of green areas is higher than in other seasons. Careful observation of the growth condition of turfgrass must be made throughout the period, and proper management for maintaining greening must be done. However, it cannot be said that measures for such matters are sufficient.

[0003]

It is well known that the weather tends to change throughout the year, but especially in summer, the surface temperature of seawater rises sharply and the evaporation of seawater becomes active, which is the source of cumulonimbus clouds. It's a matter. And, the cumulonimbus clouds become a source of rain, and it will rain everywhere, but it does not necessarily mean that there is an appropriate amount of rain, and there are days with extremely heavy rain or days with no rain at all. And the weather is always changing. Even in such an environment, it is required to maintain the growth condition of lawns and other turfgrass in green areas at all times, and the parties concerned are paying close attention to these points, but as a result, appropriate lawns are required. You have reached the point where you can't manage. The present invention aims to solve the above problems.

[0004]

Means for Solving the Invention Even if an abnormal weather such as sunshine or long rain which is likely to occur in summer is encountered by mixing turfgrass having different properties such as drought resistance, moisture resistance and negative resistance, Any of the turfgrass properties can withstand such an extreme weather environment and can keep the lawn in a green state, for example, drought-resistant turfgrass and moisture-resistant, negative-resistant properties By planting turfgrass mixed with other grass, it is possible to maintain the greening condition of the lawn with strong drought resistance even during continuous sunshine, and even if it continues to rain, the lawn grass with negative resistance and strong moisture resistance is used. It is a method of maintaining the greening state of the lawn by turfgrass having the property of being able to withstand the weathering conditions regardless of the weathering conditions.

[0005]

[Operation] Even when the ground surface becomes dry and water cannot be supplied due to sufficient watering due to continuous sunshine under high temperature in summer, by the method for maintaining the greening state of the lawn of the present invention,
By mixing turfgrass having a strong drought resistance with turfgrass having other characteristics, it is possible to keep the entire lawn in a green state by the turfgrass having a strong drought resistance without dying all turfgrass. Also, even in the summer, if the rain continues to block the strong sunlight from the sun, or if the humidity becomes high, the warm-season grass that should have grown well would be intolerable. By planting a proper amount of turfgrass having a negative resistance and a high moisture resistance, the turfgrass having a negative resistance and a high moisture resistance can endure and maintain a green state even under bad conditions such as continuous rain. In addition, turfgrasses that have the property of withstanding a lot of sand on the coast, even when the sand itself becomes hot in summer, for example, deep underground, no matter how dry the ground roots grow and the ground surface is deep. It is possible to absorb water from the whole stalk by cultivating a relatively large amount of turfgrass that has a property of sucking up enough water to sustain life and growing the standard of the stalk of the stalk. Even if there is unevenness in the presence of water, turfgrass can be kept green by growing it without dying.

[0006]

Example 1 A lawn in summer characterized by mixing turfgrass having high negative resistance and moisture resistance with turfgrass having weak negative resistance and moisture resistance but having strong drought resistance or other excellent properties. A method of maintaining vegetation in a green state so that turfgrass with strong negative resistance and moisture resistance can withstand continuous rain, and turfgrass with strong drought resistance can withstand continuous sunshine and can withstand extreme weather conditions. This is how to maintain the greening of the lawn.

[Example 2] By mixing a warm-type turfgrass of Papia grass and korai turf having a strong negative resistance with a warm-type turfgrass having a weak negative resistance such as Bermuda Douglas, a period of rainfall such as summer can be improved. It is a method of keeping grass in summer in a green state, which is characterized by being long and having the ability to endure even when there is little sunshine.

[Example 3] In a shaded portion of a tree, a building, or any other portion that blocks the irradiation of sunlight, turfgrass having a strong negative resistance is mixed more than turfgrass having a weak negative resistance, and the ratio is set to the shade. It is a method of keeping the lawn in summer in a green state so that it can be changed by changing the ratio to the point where all of it becomes strong grass with negative tolerance depending on the state of.

[Example 4] Even when deficiency of sunlight and obstacles due to high humidity are successively caused by heavy rain, cloudy weather, etc., turfgrass having negative resistance and strong moisture resistance are mixed with turfgrass which is not so that when sunshine is insufficient, However, it is a method of maintaining the lawn in the summer in which the lawn can be kept in the green state by the lawn grass that can withstand the lack of sunlight.

[Example 5] A lawn grass in summer which is capable of maintaining a lawn in a green state by turfgrass having a strong drought resistance even in the case of a shortage of rain by mixing a lawn grass having a strong drought resistance with a lawn grass which does not This is a method of maintaining a green state.

[Example 6] A turfgrass having a very long root of turfgrass, which grows deeply in the ground in search of water, and a turfgrass which grows by a stalk or a turfgrass having strong branching power are mixed. It is a method to maintain the characteristic summer grass lawn.

[Example 7] A turfgrass having a very long main root and having a property of deeply seeking water in the ground to grow and a turfgrass having a high water absorption property due to root hairs having a very large number of roots spread in a shallow area are mixedly planted. This is a method of maintaining the summer lawn in a green state, which is characterized by making it possible.

[0007]

[Effect] The present invention has an effect of maintaining a green state by constantly planting a plurality of turfgrass having properties that can complement each other so that turfgrass that can withstand even abnormal summer weather is not always withered. Especially, the turfgrass main roots are very long, and the turfgrass has the property of growing deep in the ground in search of water, and the turfgrass having a high water absorption property due to the root hairs that have a very large number of roots spread in a shallow area. Even though the properties are different from each other, it is possible to sufficiently withstand the sunshine condition by sucking water from the roots deep in the ground or over a wide area in the sunshine, such as in sandy areas near the coast where the sunshine continues. In addition, by mixing turfgrass that can withstand deep cutting or several times of cutting with ordinary turfgrass, it is possible to deepen the cutting or reduce the vigor of the turfgrass due to the increase in the number of cuttings, or die. Even if there is a risk of turfing, there is an effect that grass that can withstand such cutting will survive and maintain a green state. Also, by mixing turfgrass that can withstand the damage of pests and ordinary turfgrass, even if you encounter pests for some reason or reason, you can maintain the greening state with turfgrass that can withstand it. is there. Further, by mixing turfgrass having a higher growth rate than weeds and turfgrass having a lower growth rate than weeds, the difference in the growth rate between the weeds and the turfgrass can be visually identified or the weeds can be separated by other means. By being able to find out, it has the effect of eliminating weeds and allowing turfgrass to grow smoothly. Particularly in the summer, various weeds are easy to grow, so that it is necessary to sufficiently trim them to prevent the opening and fruiting of the weeds. Therefore, the growth condition of the weeds can be suppressed or restrained to help the growth of the grass. Also, by mixing perennial turfgrass in the cold region type turfgrass and annual turfgrass in the warm region type turfgrass, when the relatively cold summer continues, the cold region type turfgrass is more vigorous than the warm region type turfgrass, and the hot summer turfgrass. When the turf continues, the warm turf grass is made to be vigorous so that the optimum turf grass growth can be maintained at all times. And since it is a warm-type turfgrass that is an annual grass, there is an effect that the turfgrass suitable for it can be selected by predicting the summer weather. In addition, by mixing perennial turfgrass with cold climate type turfgrass and perennial turfgrass with warm climate type turfgrass, turfgrass suitable for the environment grows throughout the year, so it is a new perennial plant. There is an effect that does not require labor such as replacement. Especially in summer when the temperature is high or low, turfgrass adapted to it grows, so there is little effect on management. Also,
Newly established by growing annually turfgrass, which grows relatively faster than perennial turfgrass, by mixing annually turfgrass with cold climate turfgrass and annually turfgrass with warm climate turfgrass It has the effect of growing turfgrass and making it green in a short period of time at sports stadiums, parks, garden green spaces, golf courses, and the like. In addition, by mixing a yearly turfgrass of cold region type turfgrass and a perennial turfgrass of warm region type turfgrass,
Even in winter, in relatively warm areas, it is possible to grow warm-type perennial turf grass suitable for the soil and water quality of the land, and if it does not die for one year, then it will be relatively warm. In the short winter, turfgrass in the cold region is used to grow annual grass, and for the summer, the perennial grass in the warm region is grown in the optimum state, so that the summer lawn is warmed in the perennial season. It has the effect of making grass green.
