Description of the Related Art Conventionally, turfgrass used for golf course greens varies depending on local weather conditions, but there are many two-sided greens mainly using warm-type turfgrass and cold-type turfgrass. In recent years, more and more courses have been created to create a one-sided system with mainly cold-weed grass.

となっていた。The most used varieties of this cold-season turfgrass are the creeping type and crossbred pen cross bentgrass, which accounts for 97% of our golf course greens.
Is the adoption rate of. Since this pen cross bentgrass is a seed breeding system, the hybrid nature of various pups appears within a few years after sowing, and after repeated natural selection, it becomes unsuitable as a green grass for 10 years. Before and after the green is being renewed. In addition, the seeding method using pen cloth bentgrass has the drawback of requiring careful attention and means for the initial growth, and even if this is transferred to vegetative breeding to create a short-term grass,
Since this species was established as a hybrid, even if the stems and leaves, or stron, were shredded and rooted, strains with different characteristics with a small number of individuals competed for growth from the beginning, and from that point on. It became a spotted pattern and had foliage sparse grass, which made it unsuitable as a grass for a golf course.

載すると下記のとおりである。1) First, the breeding process of turfgrass varieties, which are the materials of the present invention, and the greeping type Bentgrass Art Create 1
The properties are as follows: a. Development of Gleaping-type Bentgrass Art Create No. 1 February 23, 1985 Otone Country Club No. 1 in Iwai City, Ibaraki Prefecture. In a 10-hole bentgrass, 20 years after sowing, 500 parts of green squeezed green of bentinggrass bentgrass with advanced natural selection were selected, and at this time, several strains that were particularly vigorous were collected. At an experimental plant of Art Greenery Civil Engineering Co., Ltd. in Higashimatsuyama City, Saitama Prefecture, which is run by the inventor, a target cultivation test study was conducted with other bentgrass, and there was a suitability for the green of the golf course.
That is, the cultivation under neglected conditions and the durability test on the green (testing on treading pressure, etc.) were carried out. As a result, what was recognized as good was transferred to the green of the golf course, and practical cultivation tests were repeated. In particular, it was confirmed that it had excellent characteristics, and this was named Art Create 1 and adopted. b. Characteristics of Bentgrass Art Create 1 No. Next, the botanical characteristics of this variety Bentgrass Art Create 1 No. 1 are described below in accordance with the criteria for examining characteristics of turfgrass by the Ministry of Agriculture, Forestry and Fisheries.

The cut Stron is shredded to a length of about 50 mm to 70 mm with a feed preparation cutter or the like. c. Pre-dispersion of Stron Carry it to a cultivated turf, such as a golf course or an amusement park, and sprinkle it with an appropriate density by manpower or mechanical force (for example, spread 3 kg of Stron over the entire area of 18 m 2. d. Planting (inserting on turf) Included) The blade part of the scraper of the automatic tiller was attached in the reverse direction from the upper surface of the stron scattered on the above-mentioned lawn (see FIG. 1), and the blade length was about 5 cm. The length of this insertion blade tip should be changed according to the hardness or softness of the grass, and it can be replaced, or if the blade can be freely moved in and out of the car frame, the length can be fixed according to the purpose. After being planted on the grass, it is run by a self-propelled roller or the like and rolled to prevent it from floating on the grass. Pressure is 3 depending on the condition of the grass 0kg~400
Use the one of kg. f. Cover protection In order to control the amount of sunlight on the upper surface of the grass after the above compaction, prevent dryness, and increase the survival rate, full-scale growth with black agricultural chiller (shading rate 50-80%) etc. Up to the coating protection.

果を有する。[0012] In this respect, by adopting a new variety of turf plant Bentgrass Art Create No. 1 cultivated for many years by the present inventor, the following effective effects are exhibited. (B) Art Create No. 1 is a turf that has been fixed and resisted natural selection in the harsh golf course greens for more than 20 years, and is a turf that has proliferated cell-differentiated from only one stem. For this reason, even in the future, unlike Pencross bentgrass, variations due to phenomena such as branching (throwback) do not occur, and the uniformity can be maintained permanently. (B) The color is the darkest green of the bentgrass, has little change due to seasonal weather conditions, and is stable throughout the year. (C) Reproductive power is more vigorous than conventional pen cloth bentgrass, and there is recovery from tread wear. (D) It has compactness and golf ball loading capacity, and is suitable for use as a grass on a golf course green due to its characteristics. (E) During the high temperature season of summer and the severe cold season of winter, the growth activity was sustained and the tolerance to both cold and warm was recognized. (F) Root system development and elongation are vigorous, and it has fast resistance. (G) As for the disease resistance, both resistance and recovery are superior as a result of performing contrast cultivation with other varieties (pen cross bent grass, etc.). (H) Next, the method of creating a lawn grass of the present invention has an effect that it can be created in a short period of time in a labor-saving manner by using an extremely simple means and using mechanical force, regardless of whether it is cold or warm. (I) Also, it can withstand continuous use as Evergreen for many years, and does not require renewal modification in a short period of time unlike the conventional Evergreen. (N) It has effects such as easy management after evergreen construction.
