"The history of pecan cultivation should not be later than the Ming Dynasty. In many local legends, there is a story of Liu Bowen's invention of boiled pecans. According to legend, Liu Bowen assisted Zhu Yuanzhang in raising an army against the Yuan. Occasionally picked up this kind of wild fruit, bit into it and tasted it. Although the meat is delicious, the outer layer of the kernel is bitter and unbearable. Later, I saw that the local peasant woman had a method of boiling wild vegetables to make dry vegetables. The sergeants collected it, not only to support the army, but also to transport it to Hangzhou City in exchange for military supplies iron, which led the mountain people to develop and utilize this unique fruit.

Pecans have high nutritional value, and after processing, they have a crisp and delicate taste. They are sought after by young people as "an artifact to nourish the brain in the office" and "a must-have snack for the next drama". The pecans in Lin'an, Hangzhou, have a fuller, fragrant taste and national geographical indication because of their unique landscape nourishment.

However, few people may know what kind of environment the pecan grows in, and what is his growth and plant protection process. At the invitation of Lin'an pecan growers, CCTV reporters went to Lin'an to visit the current situation of pecan plant protection.

After entering the Lin'an Mountains, the mountains above 75 degrees are endless. The mountains are lush and irregularly covered with pecan trees. According to the grower, Brother Yang, these trees belong to the common people. Can bring in thousands of dollars in income. But even with this high economic value, many trees are now unmanaged. The rugged mountain road leads to objective problems such as the difficulty of plant protection, the aging of the rural population, and the lack of manpower, so that the common people have to reluctantly give up their "cornucopia".

During the visit, the reporter personally experienced the main plant protection method of pecan - high-pressure spraying device. Because the spraying device is heavy, it is difficult for people to stabilize the center of gravity when moving, and it is easy to fall and cause personal injury on rough mountain roads.

Manual operation is extremely dangerous and inefficient, and the pecan tree canopy is thick. The traditional spray device has large droplets and uneven spraying, which leads to poor plant protection effect. The whole mountain of pecan trees will be gnawed.

"I have used Agricultural drone for mountains before, and they are sprayed from top to bottom. It is difficult to penetrate through, and the bottom cannot be hit. Also, it is not easy to avoid obstacles, and it is easy to hit a branch and fall off." The local grower found CCTV Reporter, I want to know if there is a better solution.

After visiting and investigating, the reporter learned that the EAVISION UAV has carried out the whole process of plant management such as pollination, fertilization, and insect removal in the pecan planting area this year. At the test base, the reporter decided to introduce us to local growers after experiencing the autonomous flight capability and mist spraying system of EAVISION Agricultural drone for pecan.

After personally experiencing the obstacle avoidance function of the EAVISION UAV, the growers raised questions about whether the aircraft can really fly smoothly and efficiently in the mountains. The reporter proposed to let the EAVISION drone compete with humans in a spraying competition, and let the growers come to see for themselves what the EAVISION drone will perform in the real operation scene!

When the workers were still adding water and medicine, the EAVISION Complex terrain agricultural drone had completed the mission and returned home, which only took two and a half minutes. The manual work has been completed an hour later.

From "inorganic availability" to "first seeing hope", the plant protection of hickory is also the epitome of the mechanization of hills and mountains in my country. The continuous development and upgrade of UAVs that can easily conquer the complex environment of hills and mountains is the road of product development that EAVISION has adhered to from beginning to end.

Looking forward to next year, there will be more "dynamic elves" in Lin'an's hickory forest to carry out services. In the development of mechanization, ordinary people can easily manage their hickory trees again, use technology to become rich, and let all things grow.
