The application of post-emergence herbicides on corn has a great influence on the post-crop crops. If the post-emergence herbicides are used improperly, it is easy to affect the normal growth of post-corn crops. What are the aspects of using herbicides after using corn? ?
1. When applying corn in the field, do: "To distinguish the varieties, do not blindly use the medicine", can be used, can not be used, do not use, control corn seedlings to produce phytotoxicity.
2, do the medicine: "Secondary dilution, do not mix water, medicine directly" especially powder type medicine.
3, when spraying, do "do not spray high spray", here, "low, high" refers to the low and high temperature.
4, when weeding: "To spray small, do not spray old", grab the weeds two leaves one heart to four leaves one heart period.
5, when weeding and pest control: "To be mixed with pyrethroid pesticides , do not mix with organophosphorus pesticides."
6, corn seedlings after the five leaves to apply: "To set a point spray, do not spray all the fields", corn 2 ~ 5 leaf stage is the best spraying time after weeding.
Due to the characteristics of low surface energy and strong chemical inertness, low degree of surface fluorination can improve the surface energy of carbon fiber and greatly improve its wettability and adhesion, while high degree of surface fluorination can further reduce its surface energy and enhance its lubricity and dispersion in solution, thus greatly expanding other application fields. Fluorinated Carbon Fiber can be used as insulator, active materials for battery, light and high conductivity materials.
