"Otherwise, let's hurry up and take the medicine, although the medicine is polluting, but now we can't control so much. If the pest is not controlled, all the pine forests on Daqing Mountain will be destroyed. ”

Guo Xinmin seemed very impatient, and as soon as he opened his mouth, he let him use the "ultimate weapon".

Lin Zhishu didn't make a sound, Feng Tiance and Lin Xiaojing both shook their heads at the same time. It's not that this method is not feasible, it is too unfeasible!

"Dad, Brother Guo, spraying chemicals is the last resort, and it can't be used easily unless it is absolutely necessary. It will take many years for the drug contamination to slowly subside, and if it is used, the ecological origin certification that our village has applied for will definitely not be approved. ”

Lin Xiaojing knows that the certification of ecological origin products in Xiegu Village has reached the final stage. You only need to come to take samples and make an ecological environment analysis report, and this is done.

But now spraying drugs, sampling and analysis are bound to be unqualified.

"Yes, Jing Jing is right. Even if you don't consider the certification, the effect of spraying is not so good, and it may not be able to control the pest. ”

Feng Tiance knows better, pine caterpillar pests, that is the nightmare of all those who are engaged in forestry. It is a deadly threat to pine forests, cypress forests, etc., which is difficult to cure.

The best way to control this pest is not to plant single-species woodlands, but to plant mixed coniferous and broad-leaved forests. This is also an important reason why Feng Tiance himself has to carry out tree species transformation from the beginning.

In his own woodland, after thinning, he replanted the seedlings according to the pattern of mixed coniferous and broad-leaved forests.

But that is a long-term effect, and it does not help the immediate crisis.

"What about biological control? Can we control the disaster?"

The biological control proposed by Lin Xiaojing is to introduce beneficial birds to eat insects and red-eyed bees to eat insect eggs. The solution is a good way, but the cost is high and the effect is slow. Again, it may not be able to control the spread of pests.

Feng Tiance explained in detail the pros and cons of various prevention and control methods, and several people fell silent, and there was really no fast and efficient means for a while.

"Uncle De, Brother Guo, be quiet, let's go down the mountain first. Jingjing can contact the technical staff of the Forestry Bureau of County H and ask them to give some support. Brother Guo, you go to the county and city to find the source of chemicals as the last option. In addition, I will go back and think about it more, and tomorrow we will sum it up again and settle down on a line of thought. Anyway, you have to take action, and you can't watch the pest break out. ”

This kind of thing can't be hesitated, a solution must be come up with tomorrow, and there is still a process from the plan to the implementation, so Feng Tiance asked several people to prepare first.

"Well, it's all up to God, let's go down the mountain first. I have already called Stationmaster Wang at the town forestry station, and he will bring someone early tomorrow morning. ”

Lin Zhishu glanced at Feng Tiance approvingly, this kid usually doesn't talk much, and he still has some rules at critical moments.

A few people walked down the mountain, and Feng Tiance separated from them at the peach forest. He was worried about his own woodland, especially the pine forests that were connected in several places, and he didn't know what was going on.

Skirting the wooden house halfway up the hill, he walked straight to a nearby pine forest. This woodland is also the place where he first picked peach blossom mushrooms, most of which are larch and masson pine. Although some broad-leaved trees were mixed with later replanting, this one was the least transformed. The tree species are relatively homogeneous.

"Tiance, there are pine caterpillars in our forest. ”

Not far from walking into the pine forest, Feng Tiance saw that Liu Yuzhu was also patrolling with a person. Before he could speak, the pillar shouted first, and it seemed that he had also found the signs of an infestation.

"Brother Zhuzi, you are talented, I came up the mountain for the matter of pine caterpillars. How many pine forests have you inspected? Is the situation serious? Take me to see it, and we'll talk ...... as we go."

The man who was with Liu Yuzhu was about the same age as Feng Tiance, tall and burly, his name was Zhang Youcai, and he was the younger brother of the "butcher" Zhang Youzhi.

The spread of pine caterpillars is very fast, and the pine caterpillars that I saw before occurred in the base, looking at the scale, Feng Tiance knew that the insect infestation this time was very serious. He followed Liu Yuzhu and the others to the place where the insects were found.

Here, it is not the west of the pine forest, but the northeast of the pine forest, close to Yuping Peak, and has reached a high slope position.

"Tiance, it's the most powerful here, and we only see sporadic bugs in other places. ”

Liu Yuzhu said while pointing to five or six masson pines, and Feng Tiance took a closer look and saw that the number of pine caterpillars was really quite a lot. Yes, they have already started to lay eggs.

"Brother Zhuzi, do you know who in our village can keep bees?"

Yiniao, it's hard to get a large batch for a while. However, red-eyed bees can be artificially bred and bred, and the cycle is not long, so it can also come in handy if you think of a way.

"Tiance, don't you know? Talented eldest brother, Butcher Zhang knows how to keep bees, but he has been raising bees for a few years and has not made any money, so he stopped doing it later. ”

Feng Tiance left the village when he was in middle school, and when he came back twice a year, how could he know this. Besides, the beekeeper's nickname is "butcher", who would have thought that?

"In that case, you are talented, you go to your eldest brother now. So I said I had something to ask him, and I would like him to come to my cottage halfway up the hill. ”

"Okay, Tiance, I'll go to my brother now. ”

Zhang Youcai answered, and trotted to find someone. Feng Tiance and Liu Yuzhu continued to search the heart of the pine forest.

"Tiance, go inside, you can hardly see the pine caterpillars, are these scourges not yet able to migrate over? Alas, the red-eyed bees alone cannot completely eliminate these pests, if they are sprayed, the wild mushrooms and medicinal herbs in the woods will be completely wasted. ”

In the heart of the pine forest, you can pick a large number of peach blossom mushrooms in spring and goose mushrooms in autumn, which is a rare treasure land. Once the chemicals are sprayed and the environment is polluted, I am afraid that the shadow of these mountain treasures will not be seen again for many years.

Whether it is a wild mushroom or a bamboo sunflower, its growth has extremely high requirements for the environment. Once the environment is no longer suitable, it is impossible to grow again.

"Well, Brother Zhuzi, my idea is also to try not to use chemical drugs. ”

Feng Tiance agrees with Liu Yuzhu's statement that the most valuable wealth of Xiegu Village is the excellent ecological environment. If the ecology of the mountain is destroyed, it will really become a "poor mountain village".

For him, he would rather lose thousands of acres of pine forest than pollute the mountain.

"Huh? That's kind of weird. Tiance, the central area of this pine forest is a forbidden area for pine caterpillars, and there is not a single one of them? There are a lot of goose fungi here......

As soon as Feng Tianshi observed, he sketched a simple topographic map in his mind, this area was the place where he had sprayed the dilution of space well water in order to promote the growth of wild mushrooms.
