 1. What is the economic value of red pine trees?
Korean pine is a very precious timber species and economic tree species in Northeast China, and it is also an important component of soil and water conservation. It can be said that red pine is full of treasures. First of all, the trunk is an important raw material for valuable furniture. Its pine needles can extract pine needle oil, and the pine roots can extract rosin and other industrial raw materials. Secondly, Korean pine nuts are edible natural green food, which are rich in fatty acids, proteins and multiple vitamins. There are about 30 million hectares of natural Korean pine forests in China. This time we came to Dunhua City, an important production area of ​​Korean pine seeds, and followed the trajectory of the T60 agricultural drone into this mysterious virgin forest.

 2. Why does the natural Korean pine forest need to be sprayed with pesticides?
During the natural growth process, Korean pine will inevitably be attacked by various diseases and insect pests. Common diseases include blight, rotten skin disease, spot disease, and pine forest nematode, among which pine forest nematode is the "cancer" of pine trees. Once discovered, widespread death will occur, and the spread can only be curbed by clearing and burning large areas. Insect pests of Korean pine include pine caterpillar, pine longhorn beetle, pine tip weevil, Korean pine ball aphid, pine tip borer, etc. Since natural Korean pine trees are 30 meters high and pine cones grow in the 30-meter-high crown, traditional artificial control Matrine fumigants are artificially sprayed to diffuse the smoke in the forest to kill the red pine cone pests, and large fixed-wing aircraft are also used to spray chemical liquids for control, but control is difficult and costly.

3. Flying control operations in Korean pine natural forests
In recent years, the price of Korean pine cones has been rising steadily. First of all, the yield of Korean pine seeds is low. A single Korean pine cone weighs about 400g-600g. It takes more than three Korean pine cones to produce 500g of Korean pine seeds. The price of Korean pine pagodas will naturally rise when the price of Korean pine pagodas grows in the off-season. Secondly, the red pine pagodas grow at the top of the canopy, making it very difficult to pick. With the popularization of the use of agricultural drones, the difficulty of pest control in Korean pine natural forests and artificial forests is gradually decreasing, which has attracted more and more contractors who have the confidence to contract Korean pine natural forests. In Dunhua City Boss Sheng of Dapu Chaihe Town led us to the natural red pine forest contracted by him and started his first pesticide application this year.

 4. Operating techniques and parameters in natural Korean pine forests
T60 agricultural drones are used to prevent and control diseases and pests in red pine forests. Users generally use the crosshair to circle the land on the remote control. In the field route mode, the omnidirectional obstacle avoidance function is turned on. For the operation scene, the mountain/fruit tree mode is selected to turn on the height fixing and detour functions. . Since Korean pine is an evergreen tree species with needles in a bunch of 5 needles, the aircrafts atomized spraying at a height of 10-15 meters relative to the canopy can also well cover the Korean pine cones at the top of the crown, ensuring the effectiveness of the Korean pine operation. It can also improve work efficiency. It should be noted that the trunks of the natural red pine forest are tall and can easily block the signal of the remote control. You need to ensure that the remote control is at a high point and in a flat and open area. You can also choose to start in a flat and open place in the ravine between mountains. Downgrade or use 4G to enhance the image transmission function.

5. Future trends (drone + red pine cone picking)
Korean pine cones generally mature from early September to early October, and can be picked after entering the mature stage. At present, the main picking methods include manual tree climbing and hydrogen balloon picking. The manual picking method is to wear a special tool with iron nails at the bottom and tie it to the feet. When climbing a tree, the iron nails are driven into the trunk of the tree to use the force to climb to the top of the tree step by step and then use a long iron hook to pick. Due to manual tree climbing and picking, There are basically no protective measures, and accidental falls are prone to occur, and the risk factor is high. Hydrogen balloon picking requires people to pick using long iron hooks in a hydrogen balloon hanging basket, with others holding the rope to control it. However, hydrogen balloons are significantly affected by the weather and are easily blown away in strong winds. Therefore, picking red pine cones has always been a problem for the industry. As the use of agricultural drones becomes increasingly mature, the use of drones has involved farmland mapping, crop growth analysis, rice and wheat yield measurement analysis, precise variable spraying, sowing, etc., in the future Whether drones can identify mature pine cones through images and pick red pine cones by themselves with manipulators or blades is still worth looking forward to.

  6. Agricultural drones protect red pine trees and increase the income of contractors, a win-win situation
Nowadays, the effect of agricultural drones on Korean pine trees has been initially and effectively verified. Agricultural drones can not only help the natural forests of Korean pine forests to prevent and control pests and diseases, but also increase income when combined with fruit-enhancing pesticides. According to feedback from Lu Xiaoying, a T50 agricultural drone user in Dunhua City, after using agricultural drones to control Korean pine diseases and insect pests, his income can increase by more than 15% compared to before without control. Taking the uncontrolled Korean pine tower as an example, the weight is about 250 grams. However, after using drone pest control and fruit-enhancing pesticides, the average weight of the Korean pine tower reaches 400 grams. Behind this harvest data is the need for agricultural drones. The affirmation of the prevention and control effect is a testimony to the take-off of agricultural science and technology.
