Description

Technical Field

[0002] With the continuous improvement of agricultural planting technology, seeds need to be treated with seed treatment agents before sowing. The purpose of using seed treatment agents is to prevent diseases and pests from occurring to seeds after sowing, avoid the damage of diseases and pests to seeds after germination, and ensure the smooth germination of seeds. Seed treatment agents include seed dressing agents, seed mixing agents, and seed soaking agents. The current conventional treatment method is to manually add different agents in the seed treatment agent in proportion, but this method has disadvantages for large-scale treatment, such as long treatment time and many times of stirring with seeds. Manual seed mixing treatment is required in small amounts and multiple times, and the treatment efficiency is low. It is not suitable for large-scale seed treatment, and the accuracy of the amount of seed treatment agent added during the manual use of the seed treatment agent is difficult to control, which can easily lead to the problem of too much or too little addition.
