Cover reporter Xu Qing Wu Yong Photography Report

The Village of Farmers' Association of Faowang Temple in Hejiang County, Luzhou City, Sichuan, surrounded the mountain along the winding cement road. On both sides of the road, bamboo was covered with bamboo. But among the rolling greens, the yellow color of the harvesting straw is very dazzling. This is the bamboo forest that has been declared dead. The culprit is the yellow -ridges and bamboo locusts, a kind of locust eating bamboo leaves.

On August 4th, the cover reporter walked into the bamboo forest of the farmers of Farmers' Association of Fawang Temple. Essence Walking in, locusts on both sides of the path were stunned, and some jumped to the bamboo leaves, some drilled into the soil, and some flew directly to the reporter. Looking up, a piece of bamboo forest showed unhealthy yellow, and the ground was already covered with dead leaves.

In 2021, Jiuxi Town, Yaoba Town and Fawang Temple in Hejiang County broke out. However, because Hejiang is in many places that belongs to the yellow -ridge bamboo locust, there is still a risk of local outbreaks. To this end, Hejiang County formulates the anti -treatment plan for the yellow -ridge bamboo locust (jumping). One battle is 2 years, and it will continue.

Farmers: L locusts who have been eaten in the past three years have suddenly died in bamboo.

On August 4th, watching the drone flying over the sky was applying medicine for his bamboo forest. Zhang Shiming pointed at a large yellow bamboo forest on the opposite mountain that these were bamboo that were eaten by locusts.

Zhang Shiming, 65, is the villagers of the Farmers' Association of Fawang Temple in Hejiang County. Zhang Shiming said that the large -scale large -scale Nanzhulin on the mountains of the village has always been his own. In the past ten years, the price of cotton bamboo is higher than that of bamboo, and Zhang Shiming's family has grown cotton bamboo in a large area.

"Cotton bamboo can be sold for 500 yuan per ton, and bamboo can be sold for 400 to 450 yuan per ton." Zhang Shiming could not say how many acres of land from the bamboo forest from home, but he sold bamboo once every three years, and he can sell 200 tons of 200 tons at home. about.

In Zhang Shiming's memory, before 2020, the bamboo forests in their own and village never appeared in such a large area of ​​locusts, and the local outbreak and spread in the past three years. "It used to be, but the amount was small, and there was no substantial harm to the bamboo." Zhang Shiming introduced that in 2021, the relevant departments in the county had invited drones to apply medicine, and the effect was good after applying the medicine. It began to start a large area again.

Zhang Shiming roughly estimated that the bamboo that was eaten by locusts this year accounted for about one -fifth. Nowadays, high temperature weather, these bamboo that is eaten by locusts will usually die in less than a month. "Unless you cut bamboo now, you can sell it for money, otherwise you can only be burned." Zhang Shiming said.

Because the summer temperature is too high, everyone is reluctant to risk artificially cut bamboo, so this part of the bamboo is often necrotic on the hill. Speaking of these bamboo that is harmed by locusts, Zhang Shiming's tone is slightly helpless.

"Last year, I was just eating Nanzhuzhu leaves, and even cotton and bamboo leaves were eaten this this year." Zhang Shiming analyzed that Nanzhu leaves are more tender and small than cotton bamboo leaves. Then, the locusts failed to let go of these cotton bamboo leaves with relatively rough taste.

Dharmaceutical personnel: continuously applying medication for about 10 days or locusts for more than 5 kg of locusts per acre

On August 4th, in the place where the farm association village was named Bamboo Forest, the players of the Flying UAV Flying Defense Force controlled a number of drones to fly over the sky and applied medicine above the bamboo forest. "We carry 9 drones in total, and each drone can load 40 pounds to 80 pounds of potions." Captain Fuyongwen introduced.

In the ground area where the operators work, the generator keeps constantly, and the drone battery is in a charging state at any time. Fuyongwen said that this heavier drone can fly for about 7 minutes each time, and each can be applied for more than 10 acres. Therefore, whenever the drone is landing, the team members need to change the battery and add potion. Affected by the weather, the operation of drones is generally carried out in the morning and evening. "The temperature is too high, and the locust will hide under the bamboo. At this time From the perspective of the area, the medicine is good. According to the data statistics from the team, some serious areas, the average locusts per mu of bamboo forest per mu over 5 kg.

The reporter learned that the players of the Flying Drone Flying Defense Force will be officially flying in Hejiang on July 27. The area of ​​this medication control is about 5,000 acres. about.

expert:

Locust relocation needs to be controlled for three to four years before the density can be significantly reduced

Where do these locust come from? Why is there still a large number of locusts in the next year after the prevention and treatment? When will the locust control have a stable effect?

With these questions, the reporter interviewed Yang Xiaohua, head of the Ecological Protection and Repairing Stocks of the Natural Resources and Planning Bureau of Hejiang County. According to Yang Xiaohua, at present, there are a total of 1.03 million mu of bamboo forests in Hejiang County. The locusts are concentrated in the three towns similar to Guizhou in Yaoba Town, Jiuzi Town and Fawang Temple. The bamboo forest area of ​​insect disaster is about 5,000 acres.

"In 2020, affected by locusts in Yunnan and Guizhou, locusts have moved to the neighboring area." Yang Xiaohua analyzed that due to the strong relocation of locusts, and at that time, the medicines in Yunnan and Guizhou were applied. The situation of Hejiang Township.

In fact, in 2021, the Hejiang County Natural Resources and Planning Bureau had performed a large area of ​​medication for regional organizations with locusts and achieved obvious results that year. Here.

Therefore, since the beginning of the spring of 2022, the characteristics of locusts from egg development to adults have been combined from the characteristics of the adults, and different preventive measures such as artificial egg digging, fixed -point temptation, smoke disinfecting, and sprayer drugs have been implemented locally. Yang Xiaohua said that although these prevention and control measures have certain effects, as the locust grows to adults on the bamboo, drones have become the first choice for prevention and treatment.

"There is also a problem with drones." Yang Xiaohua said, accompanied by strong winds, or a bamboo forest leaves were eaten, they would move with the wind. Including drone operations, due to the unable to spray large -scale spraying, the locust flavor is stimulated, and the locust will fly away. To this end, Hejiang County and adjacent Naxi District and Chongqing Jiangjin County carried out joint defense and joint control.

"Simply put, the three places work at the same time. Try to prevent the density of locusts in the three places as much as possible to prevent the locust from moving again." Yang Xiaohua told reporters that since the start of the drone prevention and control in 2021, the masses reported that the masses reported The effect is better. At the end of the year, the bamboo that was harmed by locusts also grew new leaves. Some places that were controlled last year were greatly reduced. In Hesu's locust prevention targets, there has never been the idea of ​​completely eliminating the locust. As long as a certain number of locusts will not have a substantial impact on the bamboo forest and maintain a good ecological balance.

Yang Xiaohua said that in response to the characteristics of the latch's upstreamness and relocation, Hejiang County has risen to the prevention and control area to 5,000 acres this year. The struggle with locusts will also last for 2-3 years. "The reason is that the work of one year cannot be cured. Only the continuous control of 2-3 years can obviously see the density of locusts decline." Yang Xiaohua said that it involves the development of the bamboo production industry in Hejiang County, so it must be protected by the bamboo. Essence

The Bamboo Forest of Hejiang will continue.
