If the crop is to grow well, the seed is very important. Pesticide soaking can effectively increase the germination rate of the plant, and it can better help the plant grow. So what are the specifications for pesticide soaking?
1. Note that the dosage form of the selected 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.
2. The concentration of the agent used for the precise soaking of the pharmaceutical liquid is not calculated based on the seed component, 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 controlled, the drug damage or the effect of soaking seeds can be simply caused.
3, control the soaking time of pesticide soaking seeds have a certain time request, the work will take too long to cause phytotoxicity, too short will not reach the disinfection trick. Careful soaking should be carried out according to the instructions for the use of the drug.
4, soaked seeds to be washed and aired for the poor tolerance of the seeds of the seeds after immersion, should be washed with water as required, so as not to cause phytotoxicity. If you do not elaborate on the water wash after immersion, you do not need to wash. Regardless of the demand or the need for washing, it should be spread out after drying, but some can be directly sown after soaking, depending on the variety of pesticides and soil moisture.
5, the liquid surface should be higher than the seeds in the soaking, the liquid should be higher than the seeds more than 16 cm, so that the seeds will not show up after the water swells, reducing the effect of soaking seeds.
6. Stir the seeds thoroughly into the liquid to be fully stirred to clean the air bubbles in the liquid, so that the seeds are in full contact with the liquid, and the effect of soaking seeds is improved.
