Scientific and technological forces prop up the “protective umbrella” for the “world’s first ancient pear orchard” in Gaolan

China News Service, Lanzhou, April 16th (Shi Jingjing, Ai Qinglong, Gaozhan) In mid-April, spring is in full swing. Located in the “world’s first ancient pear garden” in Gaolan County, Lanzhou City, the pear blossoms are in full bloom like white snow, and there is no one. The aircraft is patrolling at high altitude, and the “red ribbon” is hung on the tall and tall old trees to repel insects. This means that Gaolan has entered a new stage in its use of high-tech precision protection of ancient trees.

“The World’s First Ancient Pear Orchard” is located in Shichuan Town, Gaolan County. The contiguous pear orchard covers an area of ​​more than 10,000 mu. There are more than 9,000 ancient pear trees that are more than 100 years old, and the oldest pear trees are more than 400 years old. It was entered into the “Guinness Book of World Records” in 2013.

According to Yang Weiming, director of the Shichuan Ancient Pear Orchard Management Committee, since this year, the Ancient Pear Orchard Conservation Center has cooperated with the Orchard Station of the Lanzhou Agricultural Research Center to set up two test demonstration sites in the core area of ​​the Ancient Pear Orchard to carry out the use of drones to control pests and diseases. The main content of the experiment and demonstration work is anti-domination, biological bacterial fertilizer to improve the soil, biological control of pear borer and peach borer, and “belly connection” of ancient pear trees.

“Previously, the prevention and control of tree diseases and insect pests was a manual operation, which was time-consuming and manpower. Now, drones are used to spray drugs, and ultra-fine mist sprayed on the leaves at high altitude, covering a wide area, reducing artificial leakage and re-spraying, and effectively improving the prevention and control of insect pests. Efficiency.” Yang Weiming said.

At the same time, compared with the traditional way of spraying pesticides, the newly introduced “red ribbon” for insect control this year has also been recognized by the public.

Lu Xidong is the owner of a local farmhouse. There are more than 100 old trees in the ecological garden. The small pear borer on the tree may seem inconspicuous, but in fact it is a huge hazard and is likely to cause outbreaks of pests and diseases. Lv Xidong used to prevent insects on tree trunks and hired workers to spray drugs from time to time. It would take 2 to 3 days for the smell to be released after the operation. However, the effect of repeated use of drugs was not satisfactory.

This spring, Lv Xidong’s courtyard took the lead in using the new biological prevention and control technology introduced and promoted by the Guliyuan Conservation Center. This “red ribbon”-shaped migratory strip is environmentally friendly, efficient, and does not pollute the environment. As long as each pear tree is hung with 5 mitochondrial strips, the scent of the strips can be used to prevent the males on the tree from finding the females, and “lost in the direction of love” to reduce the females to lay eggs. Prevent and control pear worms throughout the year, and preserve flowers and fruits.

“A century-old tree not only has ecological value, but also confers cultural value.” Yang Weiming said that in the future, Shichuan Ancient Pear Garden will continue to explore drone control, green plant diseases and insect pests prevention and control experiments and demonstration work, scientific management and protection of ancient pear trees , To hold up a green “protective umbrella” for the century-old pear tree.
