Corn is an annual herbaceous plant in the Gramineae family, also known as corn, corn cob, and maize. Compared with traditional rice, wheat and other food crops, it has strong drought tolerance, cold tolerance, barren tolerance and excellent environmental adaptability. As a high-yield food crop in China, corn is an important source of feed for animal husbandry, aquaculture, and aquaculture, as well as an indispensable raw material for food, medical and health, light industry, and chemical industries.
From the emergence of the seedling to the jointing growth stage, if there is sufficient light, sufficient rain, and timely fertilization, the differentiation of corn roots, leaves, and stems can be completed. At the seedling stage, pay more attention to whether the corn seedlings emerge consistently, and the stems and branches are strong, laying a solid foundation for high yield of corn.
Plant protection drones at this stage are mainly involved in post-emergence weeding operations, using nicosulfuron, atrazine, and sulfimsulfuron to control annual or perennial grasses and broadleaf weeds.
