In order to control pests and diseases in production, the seeds are usually treated by pesticide soaking, and the following aspects should be mastered in pesticide soaking. Cultural stone is a general term. Natural cultural stone can be divided into sedimentary sandstone and hard slate. Artificial cultural stone products are made of inorganic pigments such as cement, sand and ceramsite through professional processing and special steam curing process.It has the advantages of environmental protection and energy saving, light texture, high strength and good thawing resistance. They are widely used for interior and exterior wall cladding.

1. The concentration of the agent used for the accurate soaking of the pharmaceutical liquid is not calculated based on the weight of the seed, and is generally calculated according to the active ingredient content of the medicament. 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.
2, pay attention to the selection of the agent of the dosage form of the drug soaked with a dilution of the drug, the agent must be soluble 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.
3, fully stir the seeds into the liquid to be fully stirred to eliminate air bubbles in the liquid, so that the seeds and the liquid fully contact, improve the soaking effect.
4, the liquid surface should be higher than the seed in the soaking, the liquid should be higher than the seed 16 cm or more, so as to prevent the seed from swelling and exposing the liquid to reduce the soaking effect.
5, the seeds soaked and washed to dry the seeds with poor tolerance to the drug after immersion, should be washed 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.
6. Master the time of soaking seeds. 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.
