"Comrade Feng Cheng, afforestation will begin soon. After reading these materials, do you have any new ideas?"
After browsing the information related to seedling raising, Qin Xuemei looked up at Li Jie and asked expectantly.
As soon as these words came out, everyone present raised their heads and focused their attention on Li Jie.
Although they had not known Li Jie for a long time, through Li Jie's daily remarks, they discovered that the 'senior' in front of them was indeed very rich.
Whether it's seedlings, afforestation, pests or diseases, or even the weather, the other party knows something about it.
"That's a little bit." Li Jie pointed to the old nursery dozens of meters away: "The seedlings in the nursery have reached the conditions for transplantation. I plan to transplant these seedlings in batches."
"In batches?"
Tan Xuemei keenly captured the key points.
"That's right." Li Jie nodded and continued: "Based on my experience in the past three years, I have found several points related to the survival rate of afforestation, namely, the amount of needles retained, the depth of planting, and the number of transplanted afforestation. Time and the way it is buried to protect it from the wind.”
Qin Xuemei understood what Li Jie meant almost immediately, and immediately replied: "You mean to conduct a control group experiment?"
"Um."
Controlled experiments are a commonly used experimental method in natural sciences, and Tan Xuemei, who has a professional background, is naturally familiar with this.
It's just that she just entered the dam not long ago, and many things haven't been figured out yet, so she didn't think of this method for a while.
Li Jie happened to wake her up.
"Where is the plan? Has it been designed?" Tan Xuemei quickly asked.
"The general direction has been determined, and my idea is to design a plan based on the four points mentioned before."
"The amount of needles retained in the four control groups was fully retained, one-half, one-fourth and one-tenth."
"In terms of depth, they are not planted deeply, and planted into one-third, one-half and two-thirds of the seedling trunk."
"There are four levels of buried soil windproofing. The first level is not buried with soil, the second level is buried with sand, and the third and fourth levels use grass soil."
"The afforestation time will start on the 25th, and a batch will be planted every ten days."
After listening to Li Jie's plan, Tan Xuemei frowned unconsciously. After a long time, she asked her doubts.
"Comrade Feng Cheng, do you have any hidden meaning in this design?"
Frankly speaking, the current plan is very complete, and it doesn't look like it was just proposed.
The other party was obviously well prepared. Even if they, the college students, did not come, and even if there was no information from the Ministry of Forestry for reference, the other party would still do this.
Therefore, Qin Xuemei wanted to hear why Li Jie designed it this way.
Li Jie took a deep look at Tan Xuemei. This girl has such a keen sense of smell.
This plan was designed by him specifically entrusted to later generations of forestry experts. Once this plan was put together, it was basically equivalent to directly telling Qin Xuemei and the others the answer.
"That's right. Saihanba is dry and windy all year round. It's difficult for larch to survive in such an environment."
"You also know that I have been planting trees on the dam for three years, but not a single sapling has survived."
"But, isn't there a saying, failure is success."
"Three years later, I have identified the key points for successful reforestation."
"And this plan is the summary of my three years of failure experience."
"From my point of view, first of all, the fewer needles left, the better, because with less needles, the seedlings need less nutrients to grow."
"Secondly, the deeper the planting depth, the better. The deeper the seedlings can absorb more nutrients, and it can also prevent the seedlings from being blown up by strong winds."
"Again, burying the soil to prevent wind is also crucial. In the first year, I didn't know anything, so I planted the seeds directly without burying the soil. As a result, all the seedlings were blown by the wind."
"The next year, I covered the pit with sand. The windproof effect was good, but the sand had poor air permeability and the seedlings were easily burned."
"Both of the above have failed. This year I want to try using Caotuo soil. Caotuo soil has strong air permeability and poor thermal conductivity, so the effect should be good."
"Finally, the time for afforestation is also very important. Compared with other areas, the spring in Saihanba is too cold, and the sunshine in summer is too abundant, so it is not a suitable time for afforestation."
"As for winter, that's not even a consideration."
At this point, everyone smiled knowingly. Although they had not seen the winter in Saihanba yet, through other people's descriptions, they already knew how terrible the winter on the dam was.
"Therefore, autumn is the most suitable time for afforestation on the dam."
Snapped!
Snapped!
Snapped!
After saying this, there was a burst of warm applause.
Seeing this scene, Wu Yansheng was so jealous that he went crazy. Suddenly, he had an idea and thought he had found a loophole in the plan.
Immediately, he immediately spoke 'sarcastically'.
"Haha, Feng Cheng, this experiment hasn't even started yet. Why do you sound like you've already seen the results?"
"In natural science, everything must be done with data. When you say that, isn't it rigorous enough?"
Li Jie glanced at Wu Yansheng lightly and had no intention of answering him.
The corners of Wu Yansheng's mouth raised slightly. He felt that he had poked a sore spot on the other party, so he quickly asked.
"Comrade Feng Cheng, can you answer the questions in my mind?"
"Wu Yansheng, could you please stop saying a few words?"
Tan Xuemei glared at him, and almost as soon as Wu Yansheng opened his mouth, she realized that the other person was trying to make him angry.
If in normal times, if Tan Xuemei spoke, Wu Yansheng would definitely agree, but it was different now.
Everything has changed!
This time, Wu Yansheng did not listen.
"Xuemei, I don't understand. I should humbly ask Feng Cheng for advice."
Sui Zhichao shook his head helplessly and thought to himself.
'Wu Yansheng's behavior is too ugly. '
'Asking for advice, is this the attitude of asking for advice? '
Na Dakui also frowned. He felt that something was wrong with Wu Yansheng when he met 'Feng Cheng'. When he spoke, he always felt a little strange.
On the other side, although Yan Xiangli continued to maintain a cold-looking attitude, he frowned unconsciously in his heart.
In his opinion, Wu Yansheng went too far and was really a villain.
Fortunately, he was not assigned to the same dormitory as Wu Yansheng.
Qin Xuemei glanced at Wu Yansheng and replied with a rather unhappy expression: "Wu Yansheng, are you asking for advice?"
Wu Yansheng did not respond directly, curled his lips secretly, and then glanced at Li Jie provocatively.
That look seems to be saying, are you a man? Why do you like hiding behind women so much?
When Li Jie saw this, an imperceptible smile appeared on his lips, and then he narrowed his eyes and released a hint of 'murderous intent' towards Wu Yansheng.
After a while, Sui Zhichao sniffed and muttered something in a low voice.
"Hey, where's the smell coming from?"
