1. Pay attention to the type of agent used to soak the seeding agent. The drug is a diluent. The agent used must be soluble in water. Can not be soaked with powder, because the powder is insoluble in water, powder floating on the surface of the water or sinking, uneven drug seed, can not achieve the effect of soaking sterilization.
2. The concentration of the chemicals used for the precise preparation of the liquid soaking is not calculated based on the seed component, and is generally calculated according to the content of the active ingredient of the agent. The soaking agent concentration is generally related to the soaking time. When the concentration is low, the soaking time can be slightly longer. When the concentration is high, the soaking time should be shortened. If the concentration is not accurately controlled, the phytotoxicity will be simple or the soaking effect will be reduced.
3, control the soaking time, soaking the seed has a certain time request, work will be too long to attack injury, too short can not reach the sterilization trick. Fine soaking time should be clarified according to the use of drugs.
4. Soaked seeds should be washed and dried. Seeds with poor endurance to the medicine should be rinsed with water after request so as not to cause phytotoxicity. If no meticulous clarification of the water after the immersion, there is no need to wash. Regardless of the demand or the need for water washing, ordinary immersions should be spread out to dry, but some can also be sowed directly after soaking, depending on the type of pesticide and soil moisture conditions.
5, the liquid surface to be higher than the seeds in the soaking, the liquid should be higher than the seeds more than 16 cm, so that the seeds appear to absorb liquid swelling after swelling, reduce the soaking effect.
6, fully stir the seeds into the liquid to be fully stirred to clean up the bubbles in the liquid, so that the seeds and the liquid full contact and improve the soaking effect.
