A question about the color of the golf course lawn, please actively help. Thank you

I don't know either, just look here!

Greens: Manila Knotweed, Bermuda, Tall Fescue, Ryegrass, Putter: Shears.

Ryegrass, early grass, tall fescue, shearling, etc. Let's take a look at these types of turfgrass.

Ryegrass lawn varietiesLike a cool and humid climate, in the winter about 10 degrees can safely overwinter, in the light is strong, the sunshine is short, the temperature is relatively low in the case of the growth is beneficial, in the winter and Bermuda mixed sowing can achieve the effect of four seasons evergreen. It is planted in many sports fields and other places.

Early maturing grass grass varietyIt likes a warm and humid environment, under the illumination of the sun, it grows rapidly, it is very strong after it is formed, it is difficult for weeds to invade, the stems and leaves are very slender and graceful, resistant to trampling, and has strong regeneration ability. The overall look is neat and even, and the plants are tightly packed. Ideal for laying all kinds of lawns in the north.

The lawn of the golf course should also be properly mowed, so that it will look beautiful and neat after mowing. And we also have to consciously maintain the lawn.

Poa, tall fescue, ryegrass, and shearweed, are usually a mix of several grasses.

Modern golf has higher and higher requirements for the quality of green turf, and the speed of the greens at the US Open has reached more than 10 feet, and the increase in speed will inevitably require the green to continue to create new lows, from the past millimeter to the current millimeter, and further to the millimeter. Creeping shearling has become the preferred grass species for golf course greens with its excellent low pruning resistance, dwarf creeping traits, delicate texture, charming color and almost year-round green period, according to incomplete statistics, the application rate of creeping shearing strands in golf course greens around the world is as high as more than 75%. However, it originated in the temperate region of Northern Europe and is a typical cool-season turfgrass, and its optimal growth temperature is 15 20, and the growth of creeping sheargrass is significantly inhibited at temperatures higher than 25.

The summer temperature in most parts of China is much higher than 25, and this year's summer in the Yangtze River basin has been higher than 35 for more than 25 consecutive high temperature weather. Under such extreme environmental pressures, if not managed carefully, the entire green of the course is threatened with death. Therefore, the summer management of creeping greens is the most important technical obstacle in the management of golf courses in China, and it is also the most headache for turf directors.

Based on our latest research results, this paper analyzes the main measures and physiological mechanisms taken in the summer management of creeping greens, in order to help golf course turf directors in China to correctly grasp the summer management techniques.

There is a book called the Golf Lawn Director's Handbook, which is quite comprehensive, and there are construction and maintenance in it, you can find it, published in Beijing. The course at Reignwood Manor is good, you can go and see it. Get off the highway at Exit 14 of Badaling Expressway, turn left under the bridge, go straight west to the head and turn right 600 meters to the east of the road.

Fairway lawns are generally mostly made of dog's tooth roots, and in the cold season areas, grassy grasses are mostly used. Generally, the height of the brake shear is centimeters.

The minimum brake height on the greens is only millimeters; The ridge ring is centimeters.

The main indicators of the quality of the green turf are: lawn uniformity, smoothness, compactness, elasticity, lawn texture, etc.

Golf grass is a very specialized grass species.

Fairway grass and green grass.

The general is the wide use of Bermuda models.

Weather temperature and humidity, the ratio of nitrogen, phosphorus and potassium content in the lawn, the basic characteristics of turfgrass species, growth cycle, common pests and diseases, the time of sprinkler irrigation and the moisture content of the lawn, the use of machinery and fertilizers and the control of weeds.

Golf course turf grass is characterized by its resistance to trampling and good regeneration. Common golf course turf grass species include dwarf Bermuda, greengrass grass, tall fescue, early maturing grass, shearweed, rye grass, Hawaiian grass, Bent grass, bison grass, knotweed, false thrift grass, blunt grass, etc.

Golf course turfgrass is characterized by grass that is more resistant to trampling, and also has a good regeneration ability, which is suitable for planting on golf courses.

What kind of grass is used for golf lawn.

There are varieties of turfgrass for golf coursesDwarf Bermuda, greengrass, tall fescue, grass, shearweed, ryegrass, Hawaiian grass, Bent grass, bison grass, knotweed, frugal grass, frugal grass, blunt-leaved grassWait.

Scissors

It can also grow healthily in alkaline soil, has strong adaptability, has strong drought resistance, is suitable for growing in sunny places, and grows quickly under the sun.

Early maturing grass

Under sufficient light, the growth of early maturing grass is very rapid, it is relatively strong after the lawn, the stems and leaves are very slender and graceful, it is more resistant to trampling, and the ability to regenerate is relatively strong, and the overall appearance is neat and even, suitable for planting on the golf course.

Ryegrass

Ryegrass prefers a cool and humid climate, can safely overwinter at about 10 degrees in winter, is beneficial to growth in the case of strong sunlight, short sunshine and low temperature, and can be achieved in winter mixed with BermudaThe seasons are evergreeneffect.

Tall and clear fescue

Tall fescue is a veryIdeal for use as a golf course lawnBecause its grass is relatively soft and evergreen for a long time, it can play a very high ornamental value. And tall fescue is a lawn that is less prone to growing pests and diseases.

Fruit Nian Qianling Grass

Greens grass, often beenIt is used for public areas such as lawns and soccer fields for golf coursesIt has a wide range of uses, has many advantages, has relatively high economic value, and is relatively simple to maintain.

Summary. The action between the club and the ball.

Elasticity - The contact between the cue stick and the ball will cause elastic deformation between the two due to the moment of contact between the club, and the elastic force will be generated to return to the original shape. The direction of the elastic force is opposite to the direction of the object's deformation and acts on the object that forces the object to deform.

Friction – When the club and ball come into contact, there is also friction that hinders the relative motion. There are two factors that affect friction: the amount of pressure between the contact surfaces and the roughness of the contact surfaces.

Therefore, the design of different clubs and balls will directly affect this friction, which in turn will affect the spin speed of the ball and the trajectory of the ball.

Friction between golf and turf.

The lawn is the foundation of the golf course. The green is the heart of the course. It is the most basic element to maintain the operation of the stadium. It is also the most important element.

The friction factor of a golf ball.

The role between man and clubWe all know that when swinging, people must swing the club to transfer the muscle power of the arms and other parts of the body to the clubhead and eventually to the golf ball. The end link hand produces force on the cue when hitting the ball, and at the same time the cue also produces a centrifugal force in the opposite direction to the human body, it is the centrifugal force of the Xiaopeng wheel that pulls the athlete's homeopathic closing action, in addition, there is also a clever friction between the arm and the cue, which is the force relationship between the person and the cue. Players should pay attention to the coordination of the force between the human body and the club, and give full play to the force of the human body on the club, because this will directly affect the magnitude and direction of the hitting force.

The elastic force between the cue stick and the ball - the contact between the cue stick and the ball will produce elastic deformation between the two due to the mutual squeezing of each other, and the elastic force will be generated to return to its original shape. The direction of the elastic force is opposite to the direction of the object's deformation and acts on the object that forces the object to deform. Friction – When the club and ball come into contact, there is also friction that hinders the relative motion.

There are two factors that affect friction: the amount of pressure between the contact surfaces and the roughness of the contact surfaces. Therefore, the design of different clubs and balls will directly affect this friction, which in turn will affect the speed of the ball and the trajectory of the ball.

Don't look at the contact between the club surface and the ball during the swing is only a short moment, but the size and direction of the force between them directly determine the direction and distance of the ball flying out.

Summary. Golf course lawns should be planned, designed and constructed according to different purposes, quality requirements and financial conditions. Before planning and design, the location, topography, aspect, slope, land area, soil conditions, hydrological conditions and vegetation of the site should be investigated in detail, and the relationship between them should be carried out.

The quality of the turf is a key issue in whether the golf course can successfully carry out recreational, competition and training activities.

The golf course grass bridge and field lawn should be planned, designed and constructed according to different purposes, quality requirements and financial conditions. Before planning and design, the location, topography, aspect, slope, land area, soil conditions, hydrological conditions and vegetation of the site should be investigated in detail, and the relationship between them should be carried out. The quality of the turf is a key issue in whether the golf course can successfully carry out recreational, competition and training activities.

Min Sun shouted. How much does it cost to care for a square meter, which can be cared for.

At present, five methods can be used in the construction of the lawn of Gaohao Erfu Stadium: laying grass rolls, planting belts, spraying, and laying green grass liquid potato blankets. Easy Carpet is a patented product developed specifically for golf course turf. In the factory, the protective layer, seed mixing layer and cushion layer are made into straw blankets by mechanical methods, and they can be laid on site.

The advantages are; The uniformity of the lawn is extremely high, the flatness is good, the construction can be paved, and the maintenance is convenient; Low shipping costs; Not afraid of water washing, flat land, slope can be used, the seed selection range is large, the speed of the lawn is fast, the cost is moderate, and the effect of weed control is very obvious; The disadvantage is that it cannot be constructed during use.
