The European classical garden is the architectural commander of the garden, generally in the central axis of the garden, there will always be a huge building, such as a castle, palace or other, the overall layout of the garden must obey the composition principle of the building, to this large building as the benchmark, to establish the main axis of the garden. Then through this main axis and then divide the corresponding sub-axis, to use wide boulevards, flower beds, pools, fountain sculptures and so on as a match.

In addition, the overall layout of the garden should present strict geometric figures, the garden road should be treated into a straight passage, and the intersection of the road should be treated into a small square form, with geometric pools and fountains distributed in points; Garden trees must be carefully pruned into cone, spherical, cylindrical shapes, etc., and lawns and flower beds must also be planted and pruned in strict geometric patterns.

Then there are the large lawn treatments, which are planted in European-style gardens and give them a reputation as outdoor carpets. There is also the pursuit of symmetry in the overall layout. For example, the layout of buildings, pools, lawns, flower beds, etc., all of them should pay attention to a whole, and achieve the harmony of numbers with geometric proportions.

Because the aesthetic consciousness of Europeans is completely different from that of Chinese, they believe that the true meaning and value of art lies in the true expression of nature, and the beauty of things is "completely based on the sacred proportional relationship between the parts." This concept of pursuing form and realism is completely different from China's concept of the unity of man and nature, and the harmonious coexistence of man and nature.

Therefore, in Hu Zhentian's eyes, this garden is very strange, the whole garden seems to be divided into square paddy fields, except that it is not the golden rice that grows in it, but the green seedlings of stubble, and these green seedlings are still being pressed on the body by pieces of figure-8 bricks, only from the hollow of those bricks to reveal pieces of green.

Hu Zhentian was as strange as others a few days ago, since he was going to plant flowers and grass, why did he use such heavy bricks to press on this grass, wouldn't this crush those grasses to death, of course they didn't know how to do it, this figure-8 brick is a kind of square brick, and it is also a kind of grass planting brick, that is, Huangshi was afraid that these turf would be damaged by them, so he specially went to purchase it.

This planting grass bricks are made of high-grade cement, medium sand, rice stone, and color pigments, and then through high-frequency vibration, with high-pressure pressing, it can be said that it is a set of interlocking and environmental protection in one, like their compressive strength, flexural strength, wear resistance, water absorption and other physical indicators, are to refer to the national standard JC-T446-2000 to implement.

When Huang Shi went to buy turf that day, he also went to B&Q once, and the sales of the tiles heard Huang Shi say that he wanted to buy bricks like the ones laid on the ground of the parking lot, so he was led to a corner.

There are really many varieties of this kind of brick in Huangshi, there are rectangular, Dutch, maple, lock, toothed, fan, cross, well, and even round, in short, a variety of shapes can be seen.

And the colors are also distinctive, there are the most common dark green, there are also traditional dark brown, and there are warm red, and the color is also very transparent. Some of the all-solid ones are like high-grade red bricks, while others are hollowed out at the corners and centers, and the prices range from the lowest 1 yuan to 45 yuan a piece.

Of course, Huang Shi wouldn't buy that kind of solid square, so his eyes were on the cross-shaped and well-shaped bricks, and the eyes of the salesperson who accompanied him were also very sharp, and he knew what to say when he followed his gaze.

So Huang Shi listened to her say, "Our clay bricks can refract more than 90% of the light, which has a good effect on protecting the human body's vision and reducing light pollution." Moreover, it has a good sound absorption effect, because it is rich in a large number of open pores with uniform and fine honey, so it can refract all or part of the sound waves, and can reduce noise when placed outdoors, and eliminate echoes when placed indoors. ”

Huang Shi nodded noncommittally, sellers will always promote the most profitable goods, so the most important thing to buy by yourself is to see if it is suitable.

Perhaps it was Huangshi's silence that made her feel like she needed to add more fire, so she continued, "This kind of clay brick is breathable, permeable, and simple, and it is installed in the parking lot, and it has good anti-slip performance......

It was also this sentence that reminded Huangshi, because although he just said that it was used in the parking lot, but in fact it was to be placed in the park, and it was to be used for people to step on.

"Give me this figure-eight brick." In the end, Huangshi made a decision and bought a car with smooth bricks.

……

The laying of this kind of square grass brick is very simple, the maintenance cost is also very low, it can be used after the construction is completed, and the road surface can be completely restored to its original state after construction. So that day, when Du Yande and the others looked at the hundreds of checkered bricks and their scalps were numb, Huang Shi picked up two bricks and demonstrated them to them.

Originally, the lawn could be covered with boards after laying turf rolls, and could not be immediately rolled by heavy vehicles or machinery, but only by rolling new turf with a lawn roller to ensure that the grass roots could reach the soil, and some irregular turf blocks had to be cut off with shovels or knives.

To ensure that the grass roots are in close contact with the soil, the new turf must be watered frequently until it is fully rooted and the turf blocks can no longer be pulled by hand. Huang Shi didn't buy a roller, so he directly carried two figure 8 bricks to the end of the aisle.

"You see, that's how these bricks are laid, just wait for me to leave a 5 centimeter width between every two bricks."

Du Yande and they originally thought that they would have to deal with muddy water again, but it turned out to be so simple, as long as these bricks were neatly placed, as for how much 5 centimeters was, they had to rely on their impressions, or look at the blank space left by the chief himself, and paved it all the way.

After all, it is a large amount of people, dozens of people work together, hand bricks and bricks, pave bricks, and soon the four lawns in the small park are paved with grass bricks, Huangshi looks at it, row by row, row by row of neat grass planting bricks, and the grass exposed in the hollow hole, it is really like the parking lot of modern society, but unfortunately there is no car on it.

So he nodded with satisfaction, "Okay, let's go eat first." ”

Du Yande, who was tired and exhausted, hurriedly greeted Huangshi, and then ran to wash his hands and eat, leaving only Huangshi and Hong'er in the park.

"Chief, why do you want to press these bricks on these turf, why don't you just lay the cement in front of you like this walkway?" Hong'er naturally had the same big doubts as everyone else, after all, she had just worked hard to lay the turf, and now she was pressing these clumsy and heavy bricks on it, didn't it seem a little redundant.

"There are many reasons for this." Huang Shi clapped his hands, in fact, he had just moved two bricks, and he only played a role of supervision and guidance when others were laying the turf.

Huang Shi pointed to the grass on the ground and the trees in the flower beds and said, "I told you about the role of these grasses and plants. ”

Hong'er nodded, not long ago, I heard the chief talk to those children in the nature class about plants, through photosynthesis, is to convert carbon dioxide and water into oxygen and organic matter, and decompose oxygen and organic matter into carbon dioxide and water through respiration, which maintains the balance of carbon and oxygen in nature.

Plants then photosynthesize carbon dioxide and water into oxygen and energy-storing organic matter under the exposure of sunlight, while releasing large amounts of oxygen. Then through transpiration, water is lost, which can not only increase air humidity and precipitation, but also reduce air temperature and form airflow, which is wind.

And because plant photosynthesis can produce organic matter, plants are the food of herbivores, which can provide energy for animals that eat grass or something. Although I still don't understand a lot of things, at least I know that these trees and meadows are very useful, and if they don't have them, then there will be drought and water shortage in this world.

"So if our parks are paved with cement or bricks, the ground underneath will not be able to 'breathe', and it will be difficult for the radiant heat it absorbs during the day to escape. But if all the grass or plants are covered, it is not convenient for us to move, after all, this is a park, a place for people to relax, and it is impossible to have only four walkways. ”

Huang Shi paused for a moment, and then said to Luxia, "Then we lay this planting grass brick is a better way, you see that the place where they are hollowed out is just for the green grass to grow, and it can also allow the land to breathe moderately." ”

"And we also need to put a few stone tables and chairs here, and also put a row of leisure chairs, so that the bottom can withstand the heavy pressure, so that the grass will not die because of our trampling, and it is also very convenient to use it as an event venue or hold an event ceremony in the future, and when it rains, we don't have to worry about the muddy ground when the heavy rain comes." In addition, this permeable grass planting brick can also waterproof and wash the soil, and can also store water to maintain the humidity of the turf. ”

"How's that, do you understand?" Huang Shi saw that Hong'er was there listening to herself, nodding her head like a chicken foraging for food, so he smiled and lifted her small chin with his fingers.

"Chief......" Hong'er looked around weakly, and her face suddenly flew red.

"Don't worry, there's no one around now." Huang Shi looked around just now, and he is not a person who doesn't know how to score inches.

"Chief, is this park built?"

"It's all built." The rectangular flower beds around it, the large round flower beds in the center, the cross walkway, the neat green lawns and grass planting bricks, plus two pairs of stone tables and chairs and a European-style street lamp on each lawn, and a row of European-style benches against the surrounding flower beds, if you can move the modern custom-made wooden promenade again, then it is already a completely modern style of community park.
