According to this method, the first half of the project was completed in less than a week, but when the excavation reached a depth of less than one meter, this method did not work very well. The soil quality of the lower layer is different from that of the upper layer, starting from less than one meter, that is, the hard sand and mud can only be dug up by manpower, and then the sand and mud can be removed.

Together with the construction of the embankment, the whole project took nearly a month, and the herringbone ditch excavated by an excavator was completed a week earlier than the reservoir pit. In order to prevent the silt from flowing into the reservoir again, Yunli planted ryegrass and a large number of mangrove shrubs on the periphery of the two reservoirs, which can have the effect of consolidating the soil.

For this project, Yunli spent more than 30,000 yuan in wages, of which the manual digging of the water storage pit accounted for most of it. However, he is not distressed, and now the irrigation problem in the southern region has finally been solved, and as for the problem in the north, he still needs to wait for the rainy season to come next year, see the effect of water supply here, and then make plans.

After the completion of the project, Yunli found that the two reservoirs looked like a big gourd, and with the herringbone ditch, it looked like a gourd growing on a vine, which had a unique flavor.

In addition, Yunli also spent nearly 10,000 yuan to purchase a small ripper truck from the county, with an eight-tire chassis structure, which can cope with the complex terrain of Xiaolushan, using diesel power, filling up a tank of fuel, sitting in the cockpit and driving to the field to work, and a large area of cultivated land can be turned over in one afternoon, which is both economical and efficient.

It is not too late to expand the cultivation in the rainy season next year, and as the year approaches, the villagers have more and more things to be busy with, and Xiaolushan has also returned to its usual tranquility.

At noon that day, after Yunli had eaten, he put on a thin coat and waited on the side of the lime road, looking looking forward to it. It didn't take long for a white car to drive slowly, and under Yunli's instructions, it drove up Xiaolu Mountain along the newly paved gravel road, and finally stopped under the big banyan tree in front of the small building.

"Professor Feng, welcome, thank you for taking time out of your busy schedule to come." After the car stopped, two people walked down from the car, one was a middle-aged man wearing big square-framed glasses, in his fifties, his hair was already half white, his face was very energetic, Yun Li greeted him with a smile and shook hands with the middle-aged man.

The other was a young man, older than Yunli, twenty-seven or eighteen, wearing a thick down coat, standing behind the middle-aged man, looking around curiously, his hands in his pockets, obviously not very fond of the cold weather.

"Xiaoli, you're welcome, it's still my fault, there have been a lot of things recently, and I haven't found a chance to come over." The middle-aged man shook hands with Yun Li warmly, let go of his body, and introduced:

"This is my nephew, and he is also a technician in the company, called Feng Jiaqi, it will be the world of you young people in the future, get to know each other, communicate more, and improve each other."

"Hello."

"Hmm."

The young man named Feng Jiaqi was obviously not as enthusiastic as his uncle, Yun Li wanted to step forward and shake his hand, but he was reluctant to pull his hand out of his warm pocket, and just nodded slightly, which was regarded as a greeting.

"Please here, my small shed is on the other side of the bamboo building, I'm not afraid of jokes, compared with those modern professional greenhouses in your company, I'm not even a little witch." Yun Li didn't care about Feng Jiaqi's cold attitude, he still smiled, and led the two of them to the direction of the bamboo building.

This middle-aged man's name is Feng Yisong, the owner of a greenhouse planting company in Linshan County, just in his early fifties, before starting the company, he was a professor of forestry at a college in the city. After retiring from his professorship, Feng Yisong opened a Feng's greenhouse planting company, focusing on the development of greenhouse cultivation and the promotion of hydroponic planting technology, which is quite famous in the industry.

More than two months ago, at that time, Yunli had just built Jifang Garden and cultivated the first batch of flower and plant seeds, both soil culture and hydroponics, with the assistance of electromagnetic force, the batch of soil culture was naturally no problem, and the results were expected. As for the hydroponic batch, the results were not satisfactory.

In fact, Yunli didn't have any experience with hydroponic plants before, and the reason why he tried this was because he returned to Xiaolushan from the welfare home that time, and soon after, he received a postcard from Lily from abroad. In the photo, she is standing in a place similar to a real yàn room, surrounded by clusters of strawberry seedlings hanging with fruits, and she is holding a plate of bright red strawberries, smiling like a flower.

After receiving this postcard, during that time, Yunli took it with him almost every day, and whenever he had free time, he turned it out to look at it, and then no one laughed loudly, which made Lu Ci see that he was in a fog, and thought that he was stimulated by something.

In fact, Yunli was indeed stimulated, in his impression, in the past years, when Lily's hair was at its most prosperous, it was only one or two fingers long, and when he first went to college, he also cut a short hair. Although I knew from Aunt Fang that Lily had long hair, now I see that it is very different from what I imagined.

Yunli could even imagine that if the two really met, he would definitely not be able to suppress his smile and laugh in front of her, and Lily would not have any scruples, and would beat himself up on the spot, just like when he was a child.

Looking at the photo, Yunli's attention gradually shifted from Lily's body to the strawberry she was holding, and the strawberry seedlings behind her.

The more information he looked through, the more interested Yunli became in this new planting technique, so he built Jifang Garden, laid those bamboo tube hydroponic containers, and tried to cultivate them while reading the materials.

The difference between hydroponics and soil culture is that soil culture is to provide nutrients to plants with the help of soil, and hydroponics is to use nutrient solution.

As long as these conditions are adequately provided to plants, they will be able to grow normally and complete their entire life cycle. Hydroponics and soil culture are essentially the same, but they are different in the form of nutrient supply. The core technology of hydroponics is how to prepare the nutrient solution so that it can play the same function as the soil and provide the nutrients needed by the plants, which is also the most difficult point of hydroponic planting.

Yunli's biggest problem is also in the preparation of the nutrient solution, according to the information on the data, the effect of the prepared nutrient solution is not good, so he thought of finding a professional to consult. By chance, when he was buying strawberry seedlings in the Luzhen market, he happened to meet Feng Yisong, who came to investigate.

As soon as they talked about the cultivation of crops, the topic of the two began to talk, and Yunli was even more overjoyed when he learned that Feng Yisong was still a hydroponics expert, and patiently asked him for relevant knowledge.

In the days that followed, whenever Yunli encountered a problem in hydroponic planting, he called Feng Yisong for help, and Feng Yisong was not too troublesome, and every time he could give Yunli advice according to the situation described, and also agreed to come to Yunli's Jifang Garden to have a look if he had time. Towards the end of the year, there are not many things in the greenhouse planting company, so Feng Yisong took time to come to Xiaolushan in person on this day to see if Yunli's works are as unique as he described.

"Jifangyuan, this name is good, the world's fragrant grass, gathered together, the meaning is good, and it is elegant." When entering Jifang Garden, Feng Yisong saw the small wooden board hanging at the entrance and said with interest.

"My Jifangyuan, is still in the process of Jifang, not after the results, you have to understand it as a verb, not a noun." Yun Li smiled bitterly and laughed at himself.

"I have also been a teacher, why is my language level so much inferior to yours?" Feng Yisong responded jokingly.

He likes Yunli's serious and free personality, which is an extremely rare quality, seriousness, which means that you have **, to get something, often you can't get rid of it, or pretend to be free and easy. It is easy for people to be indulgent, lazy, or even depraved, and they can no longer be serious. Feng Yisong, who has read countless people, can feel that Yunli is really serious and free, so he has the intention of making friends, and this time he brought his nephew Feng Jiaqi as well, hoping that he can learn more about Yunli's advantages.

"These strawberries have been cultivated for almost a month, and they rarely bloom and bear fruit just because they are grown, and the problem is probably in the nutrient solution." After entering Jifang Garden, Yunli pointed to the strawberry seedlings on the bamboo tube in the middle of the long bamboo row, hating that iron is not a steel road.

Feng Yisong helped his glasses, chose a nearby strawberry, rubbed the heart-shaped green leaves with his hand, opened the strawberry plant, checked the situation of the receptacle and the roots, and finally lifted the whole plant, like a hunting dog, sniffed the part of the roots, and dipped a drop of nutrient solution with his fingers, and put it in the light to watch.

Yun Li and Feng Jiaqi stood aside without making a sound, Yun Li knew that Feng Yisong was checking the overall condition of hydroponics. And Feng Jiaqi is even more accustomed to this, whenever Feng Yisong encounters a new situation in hydroponic planting, it is like a hound discovering its prey, the whole person's spirit is raised, and he often forgets to sleep and eat for this, overworked, and is only in his early fifties, and his hair is half white.

Then, Feng Yisong picked up a few plants one after another to check, and after a while, he said: "The elements in the nutrient solution are not balanced enough, and in the cultivation process, the timing of applying the nutrient solution is not well controlled. ”

Listening to Feng Yisong's comments, Yun Li nodded and said yes, in fact, he already had a general understanding of the problem himself, and he had made many attempts, but it had no effect.

After saying the roots, Feng Yisong pointed to the stems and leaves on them and continued: "It is commendable that the pH control of the nutrient solution is very good, and the nutrients are sufficient, which is very suitable for the growth of strawberries, so the growth of your batch is not bad." ”

"Then why can't it bloom? I saw on the Internet that a plant like mine that is cultivated directly with growing plants can bloom in three to four weeks, is there something else wrong? Yun Li was puzzled.
