In modern agricultural construction, how to correctly use fertilizers and pesticides is important for pesticide researchers, because the dosage of the fertilizers and the pesticides can not only influence the normal growth of crops, but also influence the content of the fertilizers and the pesticides in produced crops.

In the modern pesticide implementation method, a seedling soaking method is a common pesticide application method, and the seedling soaking method is to soak seeds or seedlings with a certain concentration of medicament and is a common pesticide application method when a plant growth regulator is used for preventing and treating certain seed-borne diseases. The pesticide is used for soaking the seeds, so that diseases and insect pests in the seedling stage can be effectively prevented, and the dormancy stage of some seeds is long, so that in order to break the dormancy and promote the germination and growth, the seeds are treated by adopting auxin to promote the germination and growth; some of the seed-sowing agent is added with a bird repellent and a rat killer to prevent harm, in a word, the seed-sowing pretreatment has more benefits, and is beneficial to protecting seeds, promoting germination and promoting growth. The application target of the seedling soaking method is the seeds of crops, and the concentration and the dosage of the medicament have direct influence on the seeds and directly influence the growth condition after the seeds. For the pesticide of the known seedling soaking method, the pesticide with the specified concentration can be directly used for acting on the seeds, however, for some experimental pesticides of the seedling soaking method, the influence on the seeds needs to be carried out through experiments, so the influence on various seeds of the novel pesticide needs to be obtained through experiments, and the influence on the subsequent growth of the novel pesticide can be obtained, so that the beneficial effect and the negative effect of the novel pesticide can be obtained. The operation of the novel pesticide on the seed dipping experiment cannot be operated with the implementation method of the known acting pesticide, and the specific capability of the novel pesticide can be obtained only by eliminating external interference because the seed has a plurality of factors with variable quantities in the dipping process. The traditional dipping method is directly exposed in the outside air during operation, and after the dipping of the medicament, the medicament carried on the seed coat needs to be drained, and the friction between the seeds is directly caused in the processes of taking out the medicament from the seeds and draining, and at the moment, the seed shells are relatively fragile and are not beneficial to the normal growth of the seeds. The operation of applying the novel medicament by the seedling dipping method not only needs to solve the problems, but also needs to analyze the dosage of the medicament dipped into the seeds to determine the adaptive relationship between the seeds and the medicament, so that solute and solvent in the medicament can not be volatilized and dissipated during the experiment, the seed coats of the seeds can fall off in the dipping process of the seeds, when the number of corroded seeds is large, a plurality of dipping separation objects can exist, and the residual quantity of the medicament can not be influenced by the substances falling off from the seeds.
