[0002] As the primary link in the crop production cycle, seedling cultivation is of great importance. Traditional seedling cultivation methods mostly rely on natural conditions, which are not only inefficient but also easily affected by multiple factors such as climate, soil pathogens and pests, resulting in unstable germination rate and uneven growth during the seedling stage, which seriously affects the subsequent growth and development of crops and their final yield. With the development of modern agricultural technology, people are paying more and more attention to optimizing the seedling cultivation process through scientific methods to improve the stress resistance, yield and quality of crops.

[0003] At present, the main method of controlling pests and diseases in the seedling raising process is to use low-toxic and high-efficiency pesticides rationally. However, the existing pesticide spraying devices rely on manual backpack pesticide spraying equipment for operation. This method is not only labor-intensive and inefficient, but also requires a large amount of manpower investment, which increases costs and management difficulties. On the other hand, the existing automated spraying devices on the market are mostly fixed-point installation types. They are limited by a fixed spraying range and are difficult to flexibly cover a large area of ​​seedling raising areas. They often need to be densely arranged, which not only increases the equipment cost, but also brings inconvenience to the actual operation.
