First, we must pay attention to choose the type of agent selected drugs must be dissolved 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. Second, to accurately formulate the chemical concentration used for soaking seeds is not calculated based on the weight of the seed, generally calculated according to the content of the active ingredient of the drug. The soaking agent concentration is generally related to the soaking time. When the concentration is low, the soaking time may be slightly longer. When the concentration is high, the soaking time should be shortened. If the concentration is not accurately grasped, the phytotoxicity is likely to occur or the soaking effect is reduced. Third, to fully stir the seeds into the liquid to be fully stirred to eliminate the bubbles in the liquid, so that the seeds and the liquid full contact, improve the soaking effect. Fourth, the liquid surface to be higher than the seeds in the soaking, the liquid surface to be higher than the seeds more than 16 cm, so as not to increase the liquid surface exposed after the water swelling and reduce the soaking effect. Fifth, to master good soaking time for a long time will produce phytotoxicity, too short can not reach the purpose of disinfection. Specific soaking time should be based on instructions for use of the drug. 6. Pay attention to whether the seeds that are soaked need to be washed and dried. After soaking the seeds that have poor tolerance to the chemicals, they should be washed with clean water as required to avoid phytotoxicity. If you do not specify how to wash after dipping, you do not need to wash. Whether it needs to be washed or not, it should generally be dried after soaking. However, some can also directly sow after soaking, which depends on the type of pesticide and soil moisture conditions.
