Douluo continent rumored Douluo world

Two men and one woman got off the van. Chen Chaoming stepped forward to greet the middle-aged man and said, "Dr. Zhao, thank you for coming."

"You're welcome, we don't want such a 500-year-old banyan tree to get sick and die." The middle-aged man smiled slightly.

"Is it sick?" Chen Chaoming asked.

"It looks like it is, but it may take some time before we make a conclusion on the specific situation, so please be patient," Dr. Zhao said.

"Sorry to trouble you." Chen Chaoming thanked them. These people are from the Chenghua Institute of Botany, Chinese Academy of Sciences. Zhao Jianchuan is a doctor of biology and pharmacy. He has published many very valuable academic papers and also won the provincial science and technology award. Technology Outstanding Contribution Award.

Zhao Jianchuan observed around the big banyan tree, while his two assistants peeled off a layer of dry bark from the trunk, packed it in bags, and dug up the soil to check the roots.Upon seeing this, Chen Shangyun stepped forward to help with a hoe.

"It turns out that what Grandpa Ming is busy with is asking someone to treat the big banyan tree." Chen Xuan looked on and whispered.

"That's right." Chen Lin nodded.

"This big banyan tree is the symbol of our village. It symbolizes the prosperity of our village. I hope it will get better." Chen Hua said.

They were all concerned about the condition of the banyan tree and had nothing important to do, so they stayed.One after another, other villagers heard the news and rushed over to take a look.

After nearly half an hour, Zhao Jianchuan stopped, sighed and said, "This banyan tree has brown root disease."

"What kind of disease is this? It's not difficult to treat, right?" Chen Chaoming asked.

"To put it simply, plants infected with brown root pathogen directly damage the conductive tissue of the bark, causing the transportation of water and nutrients to be hindered, causing the above-ground parts of the plant to turn yellow, wither, and eventually die. This disease is generally prevented Mainly, treatment is difficult.”

"If it's in the early stages, it's okay to say. The main source of infection of this pathogen is diseased roots, and its transmission route is mainly through the contact between diseased roots and healthy roots. Therefore, for the sake of prevention, as long as the contact between diseased roots and healthy roots can be prevented, , and kill or remove infected diseased roots in the soil, the control effect can be achieved.”

"However, the leaves of this banyan tree have withered and the infection is serious. It is estimated that the root infection has exceeded 80%. It may be too late to treat it now."

Zhao Jianchuan's words made Chen Chaoming, Chen Shangyun, Chen Xuan, Chen Hua, Chen Lin and others feel nervous.They didn't understand brown root disease or anything like that, but the meaning of Zhao Jianchuan's words was very clear - the banyan tree might be hopeless.

"Why is this happening? Can't it be sterilized or something?" Chen Shanghong asked.

"So far, there are still no formal fungicides recommended for the treatment of brown root fungus. The results of laboratory testing of pathogenic bacteria and preliminary forestry tests show that Sandefon, Sandefon, Phosphate, and Copper Sulfate are , Kuadinin, Copper Kuadinin, Pokera, Mepronin, 4-4 Bordeaux mixture and urea, etc., have certain inhibitory and therapeutic effects on this disease. However, due to the lack of complete evaluation of the test results, and legal administrative procedures for registration, it is still not suitable as a recommended preventive agent. At the same time, this pathogen mainly damages the roots, and the application of the agent is not easy to achieve the expected therapeutic effect. Therefore, the effect of applying the agent is not optimistic." Zhao Jianchuan said slowly, He shook his head and sighed.

"Is there no other way?" Chen Chaoming asked.

"The infection is too serious and it is impossible to remove the root of the disease. You can try the sterilization method. Whether it works depends on the fate of the banyan tree." Zhao Jianchuan said, looking at his unoptimistic expression, it was obvious that he was With the attitude of treating a dead horse as a living horse doctor.

When the people in Chenjia Village heard these words, their faces turned ugly. No matter who it was, they didn't want to see this tree die.

However, experts have said so, what can they do?We can only do as Zhao Jianchuan said, sprinkle the bactericidal medicine, and then resign ourselves to fate.

One day, two days, three days passed in the blink of an eye.

Chen Chaoming would stand under the tree for a long time almost every day. No matter how busy the people in Chenjia Village were, they would always take time to come and take a look. While Chen Xuan was taking care of the medicinal materials in the yard and looking for potted plants in the store, he also came to visit a few times...

However, no matter how many people pray for it, it still doesn't get better at all. The leaves are getting yellower and fewer day by day.

After Zhao Jianchuan came to see it for the last time, he shook his head helplessly and said that there was nothing he could do and he had given up treating it.

"The older generation said that this banyan tree is the patron saint of the village. There are even records that the ancestors of the Chen family once encountered a mudslide, and the whole village survived by climbing up the banyan tree. Regardless of whether these are true or false, this It's true that a banyan tree affects the mood of the whole village. It's a pity that such an old banyan tree dies." Chen Xuan shook his head and sighed. He would not pray for the old banyan tree like Chen Chaoming and spend one or two hours under the tree. When he was young, it was as if he was guarding an old friend who was about to die, but he also cared a little.

Chen Xuan was thinking about it while watering various plants in the yard. His eyes swept across the many lush fruit trees growing taller in the yard and the medicinal herbs in the yard. He suddenly stopped... The grand occasion here was different from the banyan tree. , there was such a strong contrast that he couldn't help but have an idea flash in his mind, and turned his head to look at the pile of monster feces.

Since monster excrement is so magical, would it be helpful if some were buried under the old banyan tree?

With this thought, he could no longer contain himself. He packed a few kilograms of monster feces in a bag and ran quickly to the entrance of the village.

When I came under the banyan tree, I saw that the old village chief Chen Chaoming was under the tree again. He looked up at the old banyan tree in a daze and muttered something as if he was chatting with an old friend.

"Grandpa Ming, don't be sad. Maybe this old banyan tree can survive tenaciously." Chen Xuan stepped forward to comfort him.

"Looking at it like this, the experts have given up. It is estimated that it will not survive. From now on, the village will be without it. I am really not used to it." Chen Chaoming sighed.

"Grandpa Ming, what if I can save it?" Chen Xuan said.

"Axuan, you don't need to comfort me. Old people are prone to nostalgia. It's better to be in the past. Of course, if you can really save it, I will definitely remember your great contribution." Chen Chaoming said.

"Can you rent that house to me?" Chen Xuan pointed to the tiled house not far away.

"Of course. If you save this old banyan tree, you will be a hero of the whole village. The villagers will not have any objection if it is left to you." Chen Chaoming said, but he obviously only thought that Chen Xuan was comforting him and did not let him go. In the heart.

Chen Xuan was not sure, so he did not dare to talk too much, so he sat next to Chen Chaoming and chatted with him for a while.

After Chen Chaoming left and there was no one around, Chen Xuan dug up the soil under the big banyan tree, poured out the demon beast's excrement, and then carried several loads of water to water it, trying to dissolve the nutrients in the demon beast's excrement as much as possible.

The people in the village only saw him carrying water, not burying the excrement of monsters. They all thought that it was a good thing that he had this intention, but experts said that it was not cured, so what was the use of watering it?
