Pay attention to the dosage form of the selected agent
The drug is soaked in a dilute of the drug, and the agent used must be dissolved in water. Can not be soaked with powder, because the powder is insoluble in water, the powder floats on the surface or sinks, the seeds are not evenly spread, and the effect of soaking and sterilizing is not achieved.
Accurate dispensing of pharmaceutical solutions
The concentration of the agent used for soaking seeds is calculated based on the weight of the seed, and is generally calculated based on the active ingredient content of the agent or the amount of the preparation. The concentration of the soaking agent 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 grasped, it is easy to cause phytotoxicity or reduce the soaking effect.
Master the soaking time
There is a certain time requirement for soaking seeds. If the time is too long, it will cause phytotoxicity. If it is too short, it will not achieve the purpose of disinfection. The specific soaking time should be operated according to the instructions for use of the medicine.
Soaked seeds should be rinsed and aired
Seeds with poor tolerance to the drug should be rinsed with water as required to avoid phytotoxicity. If you do not specify the water wash after dipping, you do not need to wash it. Whether it needs or does not need to be washed, it should be spread out after dipping, but some can be directly sown after soaking, depending on the type of pesticide and soil moisture.
The liquid level of the liquid should be higher than that of the seed. When soaking seeds, the liquid should be 16 cm or more higher than the seeds, so as to prevent the seeds from absorbing and expanding to expose the medicine surface and reduce the soaking effect.
Stir well The seeds should be thoroughly stirred in the liquid to eliminate the bubbles in the concentrate, so that the seeds are in full contact with the liquid and the soaking effect is enhanced.
