Abstract

<P>PROBLEM TO BE SOLVED: To achieve a method for smooth mowing, without soiling a road or without stopping traffic, on mowing grasses at a green space along the road. <P>SOLUTION: On mowing the grasses at the green space facing the road, since an inside region is mown by leaving the outer peripheral sides including parts along the road, it is possible to prevent the scattering of the waste grasses to the road on mowing the inside region due to the grasses having a high height and remaining at the outer peripheral sides, and the mown waste grasses sink naturally into the gaps of each of the grasses in the inside region after the mowing, decompose and disappear. Then, by mowing only the same inside region at several week intervals into a shorter mowing height than that in the previous times, the amount of the waste grasses becomes smaller, the waste grasses go into the gaps of the grasses even if the mowing height is lower, and naturally sink and decompose. The grasses having the high height at the outer peripheral sides are mown at the final time. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

The present invention relates to a method for cutting and managing green weeds facing a road such as a median strip of a road or a green zone between a roadway and a sidewalk.

When weeding weeds such as the median strip between the roadway and the green zone between the roadway and the sidewalk, we use a brush cutter, but because we bounce off the pebbles and hit the passing vehicle, we put a moving net in between. Have been dealt with.
In addition, it is necessary to temporarily block one lane to ensure the safety of workers when carrying out cleanup work such as loading the cut grass into packer cars and trucks and cleaning roads. Be strong. Therefore, these operations need to be performed in a short time and require 10 or more personnel. As a result, the risk is high.
Even when using a mower with a shatterproof cover, due to the capacity of the machine, it is necessary to increase the cutting height and reduce the amount of waste weed in the case of weeds that are high in extension. Since the anti-scatter cover is also high, waste grass scatters in all directions from the lower gap and soils the road.
There is no known weed cutting method that can avoid such a problem. As described in Patent Document 1, the optimal cutting time of grass and the optimal cutting time of weeds on the dike slope are grasped, and two timings are obtained. The method of mowing weeds and turf all at the same time, or setting the maximum turf length by changing the frequency of lawn mowing for each rank as described in Patent Document 2 To the extent that has been proposed, how to manage.

Japanese Patent No. 3808463 Patent No.4052861

However, even if the methods as described in Patent Documents 1 and 2 are adopted, in the case of roadside green spaces, there is an unavoidable problem that the cut grass is scattered on the road. It needs to be closed. And you can't resume traffic until you clean the road and clean it up. Moreover, such inconvenience is imposed every time the green space is cut, so the burden associated with the green space management is large.
The technical problem of the present invention pays attention to such problems, and when mowing the weeds of roadside green spaces, a method that can smoothly cut and optimally manage green spaces without soiling roads or blocking roads. It is to be realized. In addition, in green areas other than roadsides, if there is a mowing method that does not require cleaning of the harvested waste grass, it is freed from the work of cleaning and disposal, and labor costs can be reduced.

Claim 1 is that the plant height is 15 cm or more at the first time, and the harvested grass is allowed to settle naturally in the gaps between the weeds that remain after harvesting, and then the plant height remaining after at least one week has passed. Is a method for cutting weeds, characterized in that the second cutting is performed so as to be shorter than the previous time, and the harvested waste grass is naturally settled in the gaps between the weeds remaining after cutting.

According to claim 2, after at least one week has passed since the second mowing as described above, the third mowing is performed so that the remaining plant height is 3 to 10 cm, and the trimmed waste 2. The weed cutting method according to claim 1, wherein the grass is naturally settled in a gap between weeds remaining after cutting.

According to claim 3, the weed length after the first cutting is 15-30 cm, the weed length after the second cutting is 10-20 cm, and the weed length after the third cutting is 3-10 cm. The weed cutting method according to claim 2, wherein the method is a weed cutting method.

According to a fourth aspect of the present invention, when cutting the weeds of the roadside green space, only the inner region is cut away by the above method except for the outer peripheral side including the roadside portion. 3. The weed cutting method according to 3.

The fifth aspect of the present invention is the weed cutting method according to claim 4 , wherein after the inner area is cut short, the high-height area remaining on the outer peripheral side is cut as short as the inner area.

According to the sixth aspect of the present invention, after the area remaining on the outer peripheral side is cut off as described above, the inner side and the outer peripheral side are cut simultaneously to 3 to 10 cm at regular intervals with a predetermined time interval of one week or more. The weed mowing method according to claim 5.

As in claim 1, the first time the plant is cut to a length of 15 cm or longer, and after the cut grass is allowed to settle naturally in the gaps between the weeds that remain after cutting, it remains after at least one week has passed. Since the second cutting is performed so that the plant height is shorter than the previous one, weeds become less noticeable. In addition, since the cut waste grass is shorter than the first time and the amount of waste grass cut is small, even the gaps between the low-height weeds after being cut short can easily enter and hide, and do not scatter. And after 1 to 2 weeks, it will naturally settle, decompose and return to the soil.

As in claim 2, after at least one week has passed since the second mowing, the third mowing is performed so that the remaining plant height is 3 to 10 cm, and the harvested waste grass is removed. Because it naturally settles in the gaps of the remaining weeds, it is decomposed naturally and returned to the soil. In addition, it is not cut completely from the root, but is cut so that a plant height of about 3 to 10 cm remains even if it is short. Therefore, the cut waste grass is stored in the gaps of the growing grass and therefore does not scatter. So it settles naturally. Sunlight also improves and densely grows, resulting in a beautiful shoot overall.

As in claim 3, the weed length after the first trimming is 15-30 cm, the weed length after the second trimming is 10-20 cm, and the weed length after the third trimming is 3-3 cm. By setting the height to 10 cm, the allowable range of the plant height, that is, the cutting height is expanded, so that the setting of the cutting height is facilitated.
In addition, when longer than the upper limit in such a range, the plant height after subsequent growth becomes too high, and it is necessary to increase the cutting frequency. On the other hand, if the length is shorter than the lower limit, the weeds remaining in the final round are too short and the weed gap after cutting is too shallow.

As in claim 4, when weeding green weeds facing the road, the outer side including the roadside is left and only the inner region is cut by the above method, so that the length remaining on the outer side is high. Weeds can prevent the weeds from scattering on the road when cutting the inner area, and after several weeks, the cut weeds naturally settle in the gaps between the weeds in the inner area after cutting. As it decomposes and disappears, there is no need to clean and dispose of the waste grass.
As a result, there is no need to block roads and inconvenience road users, and there is no burden or danger of cleaning work, so efficient and safe weeding can be achieved.

As described in claim 5, after cutting the inner area short, the high-height area remaining on the outer peripheral side is also cut as short as the inner area, so the intended purpose of cutting high weeds along the roadside the possible achievement.
Lastly, when weaving the all-encompassing weeds on the outer periphery, if you cut it shortly in the mower and then discharge it to the opposite side of the road, it will not contaminate the road, and it will obstruct the cleaning effort and traffic The problem of becoming does not arise.

As described in claim 6, after cutting the region remaining on the outer peripheral side, the inner side and the outer peripheral side are simultaneously cut to 3 to 10 cm at a predetermined time interval of one week or more. After cutting the high-height area remaining on the outer periphery of the plant, weeds can be prevented from growing high, and you can always enjoy the beautiful scenery of the shoots.
In addition, it is not cut completely from the root, but is cut so that a plant height of about 3 to 10 cm remains even if it is short. Therefore, the cut waste grass is stored in the gaps of the growing grass and therefore does not scatter. It will settle down naturally.

It is a side view which shows the state in which the weeds are all-you-can-extend in the center separation zone of a roadway. FIG. 5 is a cross-sectional view of FIG. 5A-A showing a state in which weeds inside the median strip of FIG. FIG. 5 is a cross-sectional view of FIG. 5A-A showing a state where the inner weeds extended from the state of FIG. FIG. 5 is a cross-sectional view of FIG. 5A-A showing a state in which the inner weeds extending from the state of FIG. It is a top view which shows the cutting state of FIG.

Next, an embodiment of how the weed cutting method for roadside greenery according to the present invention is practically described will be described in detail. FIG. 1 is a side view of a green zone such as a median strip of a roadway R, and weeds 2 grow in a soil area surrounded by a concrete curb 1. Due to the unlimited growth, the weeds with high plant height 2 are not sunny and weeds with low plant height cannot grow.

As shown in FIG. 1, when weeding the all-you-can-extend weed 2, the remaining plant height is gradually shortened at intervals of several weeks in the order of FIG. 2 → FIG. 3 → FIG. I'll mow. At first, as shown in FIG. 2, the plant is cut long so that the plant height is about 20 cm, for example, and then several weeks later, as shown in FIG. 3, the plant is trimmed shorter than the previous time so that the plant height is about 10 cm, for example. . Then, after a few weeks, as shown in FIG. 4, the plant is trimmed to a shorter length so that the plant height 23 is about 5 cm, for example.

However, as shown in FIG. 2 and FIG. 3, when leaving the plant length long, as is clear from FIG. 5, leave the first all-you-can-extend weed 2 without cutting only the outer periphery of the green zone, Reap only the inside.
As a result, as shown in FIGS. 2 and 3, when the weeds on the inner side are cut, it is possible to prevent the cut weeds from being scattered on the road R side by the high-weeds 2 remaining on the outer peripheral side.
As shown in FIG. 2, when cutting first from an all-you-can-extend state, even if it is left as long as about 20 cm like the higher plant height 21, the length of the trimmed waste grass is long. However, since the weed 21 remaining after cutting is relatively high at about 20 cm, the long waste weed is hidden in the deep gap G, so it is not only difficult to scatter but also cut around. It can also be prevented that the wind is blown off later.
Moreover, the waste grass that has entered the gap G is naturally spoiled, decomposed, and returned to the soil 3. In addition, if the cutter speed of the mowers M and m in FIG. 5 is selected, and the waste grass is discharged after being shredded shortly, the decomposition is accelerated, and it settles and decomposes even in one to two weeks.

After several weeks after cutting as shown in FIG. 2, only the inside is cut again. In this case, as shown in FIG. 3, the plant height 22 is shorter than the first time, for example, about 10 cm. Reap short.
In this way, the remaining plant height 22 is shortened to about 10 cm, but since the cut waste grass is shorter than the first cut grass, the gap G between the short plant weeds 22 is effectively hidden. There is no fear of being scattered by the wind. Moreover, as time passes, it decays and decomposes in the gap G and returns to the soil 3. Therefore, no waste remains and the burden of cleaning is reduced.
In addition, if the waste grass cut off as described above is shredded and then discharged, the decomposition can be accelerated.

After a few weeks have passed since the state of FIG. 3, the remaining plant height 23 is trimmed so that it is as low as about 5 cm as shown in FIG.
As a result, the remaining weed 23 has the shortest length of about 5 cm, but the trimmed waste weed is also the shortest, so even the gap G between the shortest weeds 23 is effectively hidden and scattered by the wind. There is no fear of doing it.
As described above, the waste grass is short and the amount of the waste is reduced. Therefore, as time elapses, it decays and decomposes in the gap G and returns to the soil 3 quickly.
In the case of cutting the shortest as shown in FIG. 4, the all-you-can-extend weed 2 remaining in the surrounding area is also cut. In this case, if the inner short weeds 2 are cut off and then the weeds 2 of the outer circumference are stretched, the inner short waste weeds can be prevented from scattering to the road R side. In addition, when the weed 2 on the outer periphery that is allowed to grow is finally cut, if it is shredded shortly in the mower and then discharged to the opposite side of the road R, the road is not soiled.

In this way, after weeding the high weed 2 remaining on the outer peripheral side, we cut the weed 23 at regular intervals at regular intervals of several weeks, so that weed 23 can be prevented from growing high. , You can always maintain a beautiful landscape of shoots. In addition, when we cut regularly as short as 5 cm, only the grass that can grow at that height survives and grows to that size. The short remaining grasses come in densely because the sunlight hits them without any gaps, and the whole sun is better. As a result, the state of beautiful sprout can be maintained as a whole, and the landscape is improved.

The optimum height of the weeds 21 after the initial cutting as shown in FIG. 2 is about 20 cm, but about 15 to 30 cm is acceptable. Further, the optimum height of the weeds 22 after the second cutting as shown in FIG. 3 is about 15 cm, but about 10 to 20 cm is acceptable. The optimum height of the weeds 23 after the final cutting as shown in FIG. 4 is about 5 cm, but about 3 to 10 cm is acceptable.
If it is longer than the upper limit in such a range, the plant height after the subsequent growth becomes too high, and it is necessary to increase the cutting frequency. On the other hand, if the length is shorter than the lower limit, the weed 23 remaining in the final round is too short and the weed gap G after cutting is too shallow, so there is a risk that the waste will not be covered and will be scattered by the wind.
In addition, if the tree growing in the green zone is cut down, left as a chip and left to mulch, an earth cycle is possible, plant waste is zero, and cleanup is unnecessary.

The mowing operation according to the method of the present invention is performed by a mower such as a mower or rotary mower M, m as shown in FIG. It has a discharge port for the cut-off waste grass in front or behind and to the side of the mowers M, m, and the waste grass is shredded and discharged in the direction of the arrow. When the high weeds 2 disappear, it is possible to devise the waste weeds not to be scattered on the road R side by freely selecting the discharge direction.
In addition, when the cutting height is gradually lowered, and the time interval when periodically cutting the entire area to the shortest state is described as “several weeks”, in the fast-growing summer, it is about two weeks, In the slow winter season, an interval of about 4-6 weeks is sufficient.

As described above, according to the present invention, mowing is carried out in multiple times so that only the inside in the green zone is gradually shortened periodically, and finally the outer and inner sides are mowed at the same time. Can be prevented, and inconveniences such as traffic closure can be eliminated.
In addition, even if the waste weeds are left on the weeds left inside, they enter the gaps between the weeds and decompose naturally, so there is no risk of scattering by the wind and they will disappear naturally. Subsequent cleaning work is also unnecessary. After cutting short, the sunshine will be better overall, so short shoots will be densely populated, ensuring a beautiful natural landscape at all times. Therefore, it is also effective for green spaces other than roadside green spaces.
