After carefully inspecting the seedlings in the nursery, Qin Xuemei frowned unconsciously. She found that the seedlings seemed to be growing well, but the actual situation was not optimistic.
If these seedlings were transplanted to barren mountains, their survival rate would probably not be even one-third.
This number is too low, unimaginably low.
Seeing Qin Xuemei standing there in shock for a long time, Meng Yue couldn't help but push her slightly.
"Xuemei?"
Tan Xuemei came back to her senses and sighed.
"Meng Yue, have you noticed it too?"
Meng Yue nodded solemnly: "Well, the situation of these seedlings is a little worse than expected."
"Yes." Tan Xuemei nodded and said with regret: "What a pity, if I could have come earlier..."
Tan Xuemei didn't finish her sentence, but Meng Yue already knew what she wanted to say.
There is only a certain period of time every year that is suitable for raising seedlings. Now that the best period has passed, it is almost an impossible task to cultivate a new batch of seedlings.
This delay lasted for more than half a year. Faced with this result, they were more or less a little frustrated.
"Forget it, let's not talk about it, Meng Yue, we have to find a way to rescue him and try to improve the survival rate."
"Um."
Immediately, the two began to discuss the nursery in front of them.
"Meng Yue, I think it's best to transplant all these seedlings into beds... I remember Teacher Liang once said..."
"Uh, Xuemei, it's too much work to change all the beds, and there's not enough time..."
"..."
"..."
Li Jie listened for a while and felt that he should tell them the 'facts'.
"Ahem, you two, what you said is very correct, but it is not very applicable. Saihanba is an alpine desert area, and some issues cannot be generalized."
As soon as these words came out, the two people immediately stopped their discussion and turned their eyes to Li Jie. Then they looked at each other silently, with hesitation on their faces.
They had long known that Li Jie majored in wood processing. To put it simply, this guy came from a wild background.
This can be fully confirmed by the growth of seedlings in the nursery.
However, although the other party became a monk halfway, he took good care of the seedlings in the nursery and spent a lot of effort to cultivate the seedlings.
If they directly tell "Feng Cheng" something like, "Don't speak nonsense if you don't understand", they are worried that it will dampen the other party's enthusiasm.
Meng Yue blinked at Tan Xuemei and motioned for you to tell 'Feng Cheng'.
Tan Xuemei shook her head secretly, feeling that it would be a bit 'cruel' to point it out directly.
Looking at the endless silent exchange between the two, Li Jie couldn't help but take a step forward and interrupted their discussion.
"The survival rate of these seedlings will be beyond your imagination. According to my experience, I am afraid it cannot even reach 3%."
3%?
Upon hearing this number, the two people immediately stopped communicating, with expressions of disbelief on their faces.
Their first reaction was that it was impossible. Although the seedlings in front of them could not fully meet the standards, the survival rate should not be so low.
What is the concept of 3%?
Out of one hundred seedlings, three will survive. Rounding off, the survival rate is almost infinitely close to zero.
Li Jie sighed when he saw this, and deliberately showed a wry smile: "Don't believe it, in fact, these seedlings have a big problem, and I have only recently come around to it."
Li Jie then told the mistakes made by the 'original body' one by one, and Tan Xuemei and Meng Yue became more and more surprised with each one.
By the end, their surprise had turned into shock, because there were some issues that even the two of them, graduates of the nursery major, had not considered.
For example, the method of broadcasting, the need to consider the soil cover when sowing, the issue of planting in the same year (that is, the seedlings are transplanted in the same year), etc.
For a long time, Meng Yue looked at Li Jie with dull eyes, confusion written on her face.
"Comrade Feng Cheng, are you really a wood processing major?"
"Yeah, what's the problem?"
Looking at Li Jie who looked calm, Meng Yue's expression froze and she didn't know how to answer for a moment.
Because what Li Jie said was so professional, compared with the other party, he didn't look like he graduated from the nursery major.
Qin Xuemei hesitated for a moment and said: "Comrade Feng Cheng, although what you said makes sense, your 3% survival rate is a bit too pessimistic, right?"
Li Jie smiled and replied: "It's not that I'm too pessimistic, but the conditions on the dam are too special, but this failure is not without any effect."
"Through this failure, I came to the conclusion that if you want to succeed in planting trees on the dam, you must break the rules, think what ordinary people dare not think, and do what ordinary people dare not do."
After hearing these remarks, Tan Xuemei couldn't help but feel curious.
"Comrade Feng Cheng, can you tell me more specifically?"
"certainly."
After saying so much, Li Jie was waiting for this sentence.
"Traditionally, in order to protect the delicate seedlings, it is best to use the shade seedling method during the seedling raising stage."
"But Saihanba is located in a plateau area, and the sunshine in summer is particularly abundant. At high temperatures, the surface temperature is close to 50 degrees."
"Faced with such high temperatures, even if the saplings have passed the seedling stage, the stems of the saplings are likely to be damaged by the high temperature after being transplanted to the sand."
"Some time ago, an idea suddenly came to my mind. If we go to a shade shed during the seedling raising stage, we can directly expose the seedlings to the sun."
"Well, let's call this method 'all-light seedling cultivation'."
"I'm wondering whether the seedlings cultivated in this way will be more suitable for Saihanba?"
Upon hearing such a bold idea, both Tan Xuemei and Meng Yue couldn't help but roll their eyes.
Bold?
No, "bold" is no longer enough to describe it. "Whimsical" or "wishful thinking" may be more appropriate.
At this moment, they even doubted whether the problems Li Jie summarized before were based on hearsay.
Because anyone who knows a little bit about seedling cultivation will not propose the method of "full light seedling cultivation".
The reaction of the two people was not beyond Li Jie's expectation. He would only be surprised if they agreed with each other.
"Do you think I'm talking nonsense?"
Tan Xuemei and Meng Yue looked at each other, and then nodded in unison.
Li Jie smiled slightly and explained: "The all-light seedling cultivation I am talking about does not mean exposing the seeds directly to the sun and then doing nothing."
As he spoke, Li Jie leaned over and grabbed a handful of soil from the nursery.
"Take soil quality as an example. The soil in nurseries now is sandy soil. Sandy soil has a disadvantage. It absorbs heat quickly. When the surface temperature is high, it is easy for seedlings to get sunburned."
"But through the shade cultivation method, sunburn can be completely avoided."
"If you are growing seedlings in full light, sandy soil will definitely not be used and must be replaced with sandy loam soil (soil between sandy soil and clay)."
