The lawn is not allowed to be stepped on, so what is its significance?

The lawn can be stepped on, provided it is done in moderation, and this does not distinguish between domestic and foreign. This has nothing to do with political correctness, but only with the quality of the people and the basic national conditions of a large population. The three major characteristics of turfgrass are good recovery (also called lawn forming speed), trampling resistance, and low mowing durability.

In terms of continuity, it is obviously not as good as the grass with rhizomes, and the creeping grass with stolons, because it is a clump. However, when the planting density is sufficient, it is often used as a fairway grass, and it is only in recent years that the performance of the heat-resistant, regreening, and green period in the north is not good, and the major courses have begun to gradually replace. In addition, this grass species is often used as a pioneer grass species, which is a consensus in the industry, which further proves that continuity is not one of the three characteristics of turfgrass.

In addition, the UK's oceanic climate does speed up turf recovery to some extent, but it does not completely reverse the damage caused by human trampling. Take Winchester Stadium as an example, because it is a standard championship course, it attracts a lot of tourists and players every year, and the damage to the course is also very serious when trampled by tourists, so why can't we see it? This is because the timing of the TV broadcast is fixed, and the turf in the grass area is used to make up for it before each game, and the usual condition of the court is just a thing of the past.

Even if golf is as popular as the United States, some courses are as miserable as in China. The popularity of domestic golf is not high, the fee is also very expensive, and the frequency of use of foreign courses is more than one and a half stars higher than that of domestic courses, and the cost of manual maintenance is also high, so some domestic courses perform better than foreign courses. In addition, the turf discipline has been developed in China for more than 20 years, and our own scholars have already made achievements and innovations in the adaptation of climate and turfgrass, as well as a set of discipline systems and planting habits to adapt to China.

So the spray system can be dispersed. In China, the reason why visitors are not allowed to trample on the lawn is because of people! Too!

Many! Finish! Under the high-intensity trampling, it is not bald, it is an iron needle, even the artificial turf can be trampled bald, hard plastic, that's it, not to mention stepping on it, there are hand pulls.

1. The lawn is resistant to trampling and is relative to other vegetation. Proper pedaling is beneficial for the growth of grass, while other plants are not. For example, if you take the bear child and Erha to the lawn downstairs of the community to play, they will be fine if they play on the lawn all day...Replace the lawn with a field of flowers, a vegetable field, a sapling, any plant will die in a large area, and it will not survive the next day.

2. The limit of the lawn's trampling resistance. It is indeed limited. Just like a beautiful woman's hair, it's a good thing to comb it every day, but if you don't comb it for a few hours a day, you will be bald!

The normal amount of green lawn will not be broken if someone goes up for a walk every day and walks the dog. In extreme cases, such as the second teaching and the canteen, there is a large lawn and no stone slabs are paved, if you think about the amount of ** after class, you can step on a road in a week. I think this is a lack of design rather than a lack of trampling resistance.

3. The subject asks why not use weeds for greening. Weeds, weeds, is a relative concept, planting a seashore paspalum grows a handful of creeping shears, and the shears are weeds. The most common and annoying weed on the green lawn, the cow tendon grass, is very strong and more resistant to stepping on, but it cannot be used for greening, because the first ugly, the second is not resistant to cutting, and the third is not a lawn.

Most of the lawns in my country are not allowed to be stepped on, and I basically agree with the above classmates' statements about the lack of public space in our country. Indeed, in a country with a population of nearly 1.4 billion people, and the population is mainly concentrated in.

In first- and second-tier cities, the lack of public space is obvious. Take Beijing and Guangzhou as an example (one for the north and the other for the south), Beijing has a population of more than 2k people, and even if it is divided into several districts, each district is also a few million people. Moreover, Beijing's climate belongs to the northern transition zone of rain and heat at the same time, and the lack of water resources is more serious.

If you can step on the lawn, it will become hard ground in 3 days! Guangzhou is mentioned because it is a more suitable southern city for growing grass than Beijing, and although there are many open grasslands, they are often bald or in poor condition. As the saying goes, there is no road on the earth, but when there are many people walking, it becomes a road.

This is mainly because trampling on the lawn can have two effects: one is to cause soil compaction, and the other is to cause lawn wear.

Soil compaction leads to the reduction of soil porosity, which leads to the deterioration of soil aeration and water permeability, affects the absorption of nutrients and water in the soil by turfgrass roots, restricts the growth of roots and reduces the vitality of roots, and then inhibits the growth of stems and leaves, thereby reducing the tolerance of turfgrass to adverse environments such as heat and drought, and increasing the susceptibility of turfgrass to burns and direct low temperatures. If the soil is compact, accompanied by prolonged periods of high humidity, it often leads to an increased incidence of turfgrass. In addition, soil compaction changes the physical properties of the soil, giving some plant species a relative competitive advantage over another, for example, some weeds can germinate under low soil permeability, while most turfgrasses do not, resulting in the decline of turfgrass species, the invasion of weeds, and the change in the initial composition of turfgrass communities.

Abrasion refers to the damage caused by external force directly to the grass tissue extrusion and tearing of the turf, which is mainly manifested in the mechanical breakage of turfgrass stems and leaves caused by external force, especially when the turfgrass is dormant due to frost or wilting, dormant in winter, and the tissue becomes hard and brittle, this kind of external force with a certain sudden change causes serious wear and tear of the lawn, which is also the reason why it is strictly forbidden to trample on the lawn when the lawn is dormant in winter. Studies have shown that golf cart traffic on the lawn can cause immediate turf wear and tear, which increases with the number of passes.

Reasons why it is not permissible to trample on the lawn.

A lawn trampled is not good-looking.

Two. If there are a lot of people trampling on the lawn, then there is a possibility that the grass of this lawn will die, and it may become a road.

Therefore, such regulations are for our life, so that the environment can be better. Each of us should consciously abide by it and not trample on the lawn.

In fact, the reason why there are such regulations is to regulate those who are unconscious, so that they can develop a conscious compliance with the rules or regulate their own behavior.

I hope that each of us can consciously abide by it from ourselves. Our environment has become more beautiful.

Of course, it is not allowed to trample on the lawn. In fact, we all know that everything has a certain vitality and a certain growth, and if you trample on the lawn at will, not only will it destroy the environment, but it will also cause serious damage to the vegetation, and over time, you will let the grass of these lawns dry up, and cause environmental damage. I think that not trampling on the lawn is at least an expression of civic morality.

"Not trampling the lawn" has been a virtue called for by society for a long time. There are mainly the following reasons:

1.In urban construction, ornamental lawns are blindly built, and trampling lawns are rare.

Nowadays, many urban construction adopts the unscientific practice of blindly building ornamental lawns. Many lawns refer to "foreign grass", and these "foreign grass" varieties are selected because of their ornamental value, but they ignore the practicality of these "foreign grasses" and are very resistant to trampling. In desperation, the practice of calling on people to take care of the lawn is to "stay away from the lawn".

2.The degree of urban greening is not high, and lawns become the object of protection.

The continuous rise of reinforced concrete buildings in the city continues to erode the green space, and the growth of greenery cannot meet the needs of the residential population. The limited green lawn becomes a public protected place.

3.People's awareness of social morality needs to be strengthened.

The consequences of stepping on the lawn are: trampling the lawn is easy to cause soil slabs to reduce the oxygen content of the soil and is not conducive to the growth of plant roots Eventually lead to the death of plants for the so-called do not trample slogan Not only to say not to walk on the lawn but also to remind pedestrians not to dispose of garbage on the grass Do not damage the grass is alive, nature gives us all kinds of creatures equal opportunities to survive and coexist peacefully, grass can not be trampled casually, it condenses the hard sweat of gardeners, is the harvest of labor, You can't just follow it.

Poop is stepped on, that is disrespectful to workers and labor.

Also, lawns are an important part of greenery, and if everyone tramples on lawns, then sooner or later nature will be destroyed, and eventually humans themselves will be endangered.

When the high school leader caught the school leader stepping on the lawn, he smiled and said, "You don't know that this grass will grow more and more when you step on it."

Summary. Kiss, it's a pity to step on the green carpet for the second time, why not take a few more steps<> 2, it's a pity to break the green carpet, why not take a few more steps.
