Qingyixiao's interior decoration has not yet been completed, and Lin Zeng has also focused on other places for the time being.

Lightweight electric vehicles traverse city streets. Since Lin Zeng began to consciously work in the direction of urban greening, he no longer unconsciously ignored the surrounding environment, he began to observe the city in more detail.

The ground is usually concrete and asphalt. The walls are tiled veneer. Those pedestrian bridges built of steel and concrete, overpasses have some vertical embellishments. However, the green plants of the vines are not well maintained, and they look sparse.

If you change it to planting, you can easily achieve excellent planting results. It doesn't take much manual maintenance to give these dusty flyovers a new look and become a veritable green bridge.

Lin Zeng thought with confidence.

During this time, Lin Zeng consulted a lot of information about urban greening, especially the current situation and prospects of urban three-dimensional greening in China.

At present, three-dimensional planting in the world mainly relies on three-dimensional planting utensils. For example, non-woven bags are used as planting containers and arranged on the wall. In addition to this bag type, there are also paving type, basin type, and modular.

Abroad, there are organizations that specialize in how to move garden gardens to the walls. After careful planting and care, it can form a more natural green surface on the wall.

The green wall brings the natural grass and garden indoors, making the simple flat wall fresh and flexible.

But in China, the technology in this area is still in its infancy. Although greening companies have sprung up to start three-dimensional planting, the technology is not mature. Three-dimensional planting requires several times more maintenance effort than ordinary green planting. Planting equipment, drip irrigation equipment, nutrient solution supply and other problems, so that three-dimensional greening is not popular in China.

But for Lin Zeng, there are no technical problems at all. He can refine vines that are suitable for growing on the facades of cities. If it is indoor three-dimensional greening, you don't even need to consider factors such as light, as long as there is enough wall space, you can plant suitable wall plants.

For those who buy vine tomatoes and vine leafy greens, they have already achieved three-dimensional cultivation in their own homes on a small scale. Moved the vegetable garden into a city apartment.

Online retail is aimed at family customers, while another sales model is aimed at large public green spaces. Large shopping malls, schools, hospitals, and the common areas of the city managed by government departments are all potential customers.

At present, Lin Zeng has not yet taken the design results, and Qingyi Small Campus will be his first experiment.

Thinking about it does not hinder his riding. The streets of Qinghe City are not crowded on a summer afternoon, the sun is a little hot, and the branches and leaves of the street trees are luxuriant, and driving in the shade of the trees is not afraid of the scorching sun.

Lin Zeng's destination was the Beihu Bird and Flower Market in the south of Qinghe City. This is the largest flower and bird market in Qinghe City. Originally in the urban area, with the soaring land price in the urban area of Qinghe City, the original land of the Beihu Bird and Flower Market was requisitioned for other purposes, and the entire Flower and Bird Market was relocated to the southern suburbs of Qinghe City.

Although the new flower and bird market is larger and has a better environment, it seems that it is still a little less popular.

Lin Zeng parked the electric car and walked into the gate of the flower and bird market. The streets of the market are spacious, but there are few people, especially at this time, just after noon, and it is not a weekend, and there are not many customers on the whole street. In some shops, you can't even see the figure of the owner.

Although the flower and bird market is named flowers and birds, it is not only the literal ones that are purchased. Flowers, birds, fish and insects, stone carving and wood art, pet cats and dogs, cultural play coins, all kinds.

Lin Zeng walked from the shop on the left, and looked at it as he walked, dizzying. Facing the shop on the left side of the street of the flower and bird market, mainly engaged in ornamental fish, Lin Zeng went to see the flowers, looking at the fresh, but did not have the intention of buying.

His purpose is very clear, he came to the flower and bird market to choose suitable plants.

After passing the ornamental fish trading area, turn right and you will be greeted by lush greenery.

When Lin Zeng saw these shops, his spirit was shocked, and he no longer looked casually and casually, but walked directly to the inside of the shop and looked at the flowers and trees inside.

Lin Zeng walked into a store with a large façade, and the two sides of the store were full of all kinds of flowers and plants, which were staggered and beautiful.

When I entered the store, I immediately felt a burst of coolness, and the heat was completely gone. If you look closely, you can see that there are many kinds of plants in the store. Lin Zeng knew bamboo, mint, evergreen, rose, jasmine, kumquat, bergamot, fortune tree, lavender......

"Brother Youth, what do you want to buy?" mixed with the inquiring voice of the local dialect of Qinghe City, came from behind Lin Zeng.

Lin Zeng turned his head to see a dark-skinned middle-aged woman holding a bowl of white rice and greeting him warmly. There were also a few pieces of braised pork and green vegetables stacked on top of the rice, it seemed that the boss was eating, and when he saw Lin Zeng coming in, he hurriedly came over to greet him.

"It's okay, I'll see. Lin Zeng smiled, although he had several plants that he wanted to buy, it did not prevent him from taking a look at them and buying more plants to go back to practice.

"Okay, take a look at it, ask me if you have anything. "The middle-aged aunt's Mandarin is very blunt, but Lin Zeng can still understand it. I don't know if it's because it's not easy to meet a customer in the off-season of sales, and the owner greets customers very warmly.

Lin once walked around the store and asked the prices of several plants, and he knew it.

"Little brother, the price of the aunt is not expensive, you go to the nearby store to take a look, my family sells the cheapest. The middle-aged aunt sat on the bench in the corner, picked up the rice and said, "Our family's flower farm is in Yongde County, next to Qinghe City, and the cost is relatively low. ”

Lin Zeng nodded, he didn't want to bother, and directly reported the list to the shopkeeper.

"Give me one rose seedling of various colors, two pots of mint, two pots of lavender, is this the moon season? Give me one of all colors...... Lin Zeng chose all annual seedlings, the price is not expensive, but he bought a lot of types, the middle-aged aunt quickly put down the dishes and chopsticks, and cleaned up the flower seedlings for him.

"Boss, is there any grass for the lawn to sell?Also, do you sell climbing plants with thorns?" Lin Zeng bought a number of flowers and grass seedlings, and asked after thinking about it.

"Yes, but it's not in the store, this is a green seedling, not in the store, how much do you want, little brother?" The middle-aged aunt smiled and packed the flower and grass seedlings that Lin Zeng bought in a black plastic bag, "Thorny climbing vines, we don't have them, but I seem to remember that there are wild vines in the mountains, and the spikes are sharp, and if you accidentally scratch them, it will be a bloody wound." This wild vine also has large purple flowers, which is very beautiful. If the younger brother wants to buy it, you can ask my son to dig a few for you next week. ”

"Okay, but the area I use is not large, can you dig two or three square meters for me first. Lin Zeng looked at the middle-aged aunt who was using a calculator to calculate money, and asked tentatively.

"Okay, or you give me a deposit of twenty yuan, and my son will go back to the flower garden in the next few days and bring it to you." ”

"Okay," Lin Zeng readily agreed.

Flowers and seedlings are packed, and there are not many. Lin Zeng thought that the soil at the roots was too heavy, so he asked the shopkeeper to take off all the pots of flowers and plants, and the soil at the roots was shaken off.

A middle-aged aunt once kindly reminded that planting with potted soil is definitely easier to survive.

However, Lin Zeng knew his own affairs, and he didn't mind the survival rate at all. He didn't buy these plants to grow them.

At Lin Zeng's insistence, the middle-aged aunt had to help him take off the pot and shake off the soil on the root system of the plant.

Lin Zeng bought about 20 kinds of plants, totaling less than 300 yuan. The middle-aged aunt also deducted the money for the flower pot he didn't want.

After paying, Lin Zeng temporarily stored the flowers and seedlings in the store. He's going to take another look at the flower and bird market to see if there's anything else worth buying.
