From the perspective of agricultural modernization mechanization, mechanized operations have been achieved from farming to planting to harvesting, but plant protection has not achieved mechanized operations.
Because plant protection requires high mechanization, it is in the growth stage of crops and is indestructible. There are problems in manual control operations. For example, there is water in the rice field, it is cumbersome to go in rubber shoes, and there is a risk of scratching the feet when going in barefoot. For high-stalk crops such as corn, artificial spraying can cause damage to the branches and leaves of the crop. In addition, there is a problem of high seedling destruction rate during the operation of ground-propelled plant protection machinery. We occasionally see some foreign countries that use large manned aircraft to spray pesticides, but large aircraft spraying has many disadvantages. Although it is still being sprayed, the penetration rate is the highest. 30%, most areas in the country do not have the conditions, and the effect of pesticide application is not ideal. Then the drone is more adaptable. Through aerial operations, it is not subject to terrain factors such as mountains and paddy fields, ridge cropping, flat cropping and other planting methods, high stalks, short stalks, fruit and crop growth cycles. problem.
