Chapter 445 The Mystery of the Dead Fir Tree

"Do you still remember that Dr. Sea Turtle at the job fair yesterday? Didn't he have a copy of the genetically modified technology information from the Nanshan Group in the United States. According to him, if the seedlings bred with the genetically modified technology can grow under the same growth cycle , the growth rate can be more than twice as fast as that of similar tree species, and it will also increase the yield of wood, improve the quality of trees, and have excellent resistance to diseases, insect pests, and wilting agents.”

Hearing what Ling Zikai said, Zhang Nan understood the meaning of what he said just now: "You mean, these fir trees may be bred through genetic modification? Since they are not affected by soil conditions, climate and other conditions, beyond In terms of the growth pattern and rapid growth of similar tree species, this may be possible. In addition, this transgenic technology is not yet mature, and in the process of practical application, unstable factors have appeared, causing some defects in tree life cells. So in the process of rapid growth, mutation occurs, and death occurs."

Originally, Ling Zikai only speculated in his mind because he saw the returnee postdoctoral fellow in Musen Company.Now after listening to Zhang Nan's analysis, this suspicion became stronger and he asked:
"Is there a way to identify these trees as being genetically modified?"

"Of course, you just need to extract the genetic DNA of two trees for comparison! Isn't the set of laboratory equipment that Professor Lin rented from Linda is still in the forest farm? You just need to take a piece of fir tree wood from here, Then find a fir tree from the Yunhai Forest Farm and give it to Professor Lin, and you can find out after a laboratory test!"

The two of them were talking about forestry technology. Zhang Jun listened to it half-understood. Looking around, he suddenly said: "No, look, besides these fir trees, I see a few other trees. The trees seem to be starting to wither!"

Seeing Zhang Jun pointing to a few red pines not far away, Ling Zikai and Zhang Nan quickly looked over.

I saw that although the red pines were not dead, the pine needles on the branches were a little sparse, and a layer of needles fell on the ground around the roots.

Although it is said that it is the season of autumn, and it is a normal natural phenomenon for trees to shed their leaves, the red pine is an evergreen tree, and it is impossible for the needles and leaves to fall off, leaving only bare branches. Obviously, those few red pine trees have also become sick .

Zhang Nan ran to the red pine tree to check the reason, but Ling Zikai did not follow, but sat down on a bare rock.

If he wanted to know whether the trees in the forest were growing normally, he had a simpler method, which was to use the consciousness of the ancestral gods to detect the life breath contained in the trees.If the breath of life is strong, the growth of the tree is naturally healthy, otherwise it is abnormal.

When the consciousness of the ancestral god began to cover the entire hill, Ling Zikai obviously felt something abnormal.

Although affected by different regional environments, the vitality contained in the trees growing in each place is different.

Like Tiger Leaping Stream, a secret place that has maintained a primitive ecological environment for tens of thousands of years, every plant and tree growing inside can be described as full of spirituality, and the vitality contained in it contains essence elements.

Secondly, there are primeval forests like the old forest, which are all towering trees that have grown for tens of hundreds of years.Because during the long growth process, it constantly absorbs the vitality of the world, and over time, a part of the essence of vitality will be deposited in the body, so the vitality is also very strong.

Even the vegetation in the Yunhai Forest Farm is thriving thanks to the fertile soil and suitable climate.

And the vitality exuded by these trees in front of him can only be described as sluggish.

Naturally, the dead fir trees should not be ignored. Even those healthy trees seem to be under threat of survival, and they seem to be in a state of panic all day long.

What is going on here?
Ling Zikai felt a little puzzled, and after exploring back and forth between the trees for a while, he finally found some clues.

This abnormality comes from the dead fir trees. Although they no longer have the breath of life, there is a faint gray breath from the dead branches and rotten leaves.

This kind of breath seems to be very corrosive. After it is emitted, it attaches itself to other surviving trees, slowly devouring their vitality.

The entire forest seemed to be shrouded in a terrible plague silently. If it could not be effectively prevented and controlled, it would not take long for all the trees to die.

What is this gray breath?
After Ling Zikai pondered for a while, he quietly released a trace of ancestral god energy from inside and outside his body.

When the energy came into contact with that gray aura, Ling Zikai instinctively felt disgusted.

At the same time, those gray auras seemed to have met their nemesis, avoiding the energy of the ancestor god one after another.

Some of the gray aura disappeared as if suddenly evaporated after touching the energy of the ancestor god.

After realizing that the energy of the ancestor gods can restrain these gray auras, Ling Zikai did not destroy the energy to wipe them all out.

One reason is that this gray aura has almost permeated the entire hill, and it would take too much energy to wipe it all out;

Secondly, even if the gray aura in front of him is eliminated, who knows if new auras will spread from other places, this can only treat the symptoms but not the root cause, not a long-term solution.

At this time, Zhang Nan also came back and said: "Those red pine trees do seem to be abnormal, but it is also impossible to determine the reason! Why don't you ask Professor Lin to come and have a look, he is the Experts in this field!"

Although he already knew that the death of the trees must be directly related to those gray breaths, Ling Zikai couldn't tell the answer.

The key question now is to find out how these gray breaths appear and where is the source!
After pondering for a while, Ling Zikai asked: "Nan Nan, I have a question for you. In the animal world, some infectious diseases often occur, such as bird flu, tuberculosis, rabies, etc. In the plant world, Will something similar happen?"

"Of course there will be infectious diseases!"

Zhang Nan said affirmatively: "Infectious diseases of plants can be divided into two categories: one is non-infectious diseases, caused by abiotic, such as lack of nutrients, insufficient or excessive water, low temperature freezing damage and High-temperature burns, unreasonable use of pesticides and fertilizers, or poisoning caused by waste water and waste gas, etc.

The second type is infectious diseases.Diseases caused by fungi, bacteria, nematodes, or parasitic species, such as discoloration, necrosis, decay, wilting, and deformity.

The most common pine needle rust and five-needle pine blister rust are important forest diseases in the world. They are called the plague of the plant kingdom. When the disease is severe, the entire forest can be killed. "

Ling Zikai asked: "Then do you think the fir trees we see are suffering from the plague?"
