1. can reduce seed consumption. After careful coating, the germination rate and uniformity of corn seeds are improved, and precision sowing technology can be used. While greatly reducing the seed consumption per mu, it can ensure the completeness, uniformity and Miao Zhuang of the field seedlings, thus reducing the production cost and labor intensity.
2. Prevent the occurrence of pests and diseases. Corn seeds are coated and sown in the soil, forming a protective barrier around the seeds, which can avoid the invasion of pests and diseases in the soil. When the seeds swell, germinate, germinate, emerge and grow, the drug film will not melt immediately, and the systemic drugs will be slowly released from the drug storehouse, gradually absorbed by the corn root system and transmitted to all parts of the seedling root system, thus continuously playing a medicinal role in preventing and controlling pests and diseases.
3. Promote plant growth. Corn seed coating agent contains trace fertilizers and hormones to promote plant growth. The coated seeds showed that the roots of the seedlings were many, short and thick, and they grew vigorously.
4. It can reduce pollution. The application of corn seed coating agent was changed from open-air application to hidden application, which not only delayed the application time at seedling stage in field, but also reduced the application times at seedling stage, thus reducing air and surface pollution.
