Detailed Explanation of Plant Growth Regulator Application Methods
Plant growth regulators are a type of pesticide commonly used in planting and production. Reasonable use of plant growth regulators can effectively enhance crop growth capacity and improve crop yield and quality. However, many people do not know how to use plant growth regulators. So today, the editor brings you the application methods of plant growth regulators. Let's take a look below!
1. Solution spraying
Solution spraying is the most commonly used method for plant growth regulators. First, we need to prepare the solution according to the concentration requirements, and then spray it. When spraying, the solution should be fine and sprayed evenly to ensure the sprayed parts are moist. At the same time, in order to ensure that the solution can adhere well to the plants, an appropriate amount of emulsifier can be added, such as washing powder or some surfactants. This improves the adhesion of the agent, and when spraying, we should pay attention to spraying it on the target parts.
2. Soaking method
Soaking is mainly used in the cutting propagation of crops to improve the rooting rate of cuttings. It can also be used to treat seeds and ripen fruits. For example, for some woody cuttings with leaves, we can soak them in indolebutyric acid for about 10-20 hours, and then insert them directly into the seedbed. There is also a quick root-dipping method, using a mixture of naphthaleneacetic acid and talcum powder, then wetting the lower part of the cuttings, dipping an appropriate amount of the powder, and inserting them into the seedbed.
3. Smearing method
The smearing method is to apply plant growth regulators to one part of the crop. Commonly used carriers include lanolin. Directly apply the lanolin containing the agent to the area to be treated, generally focusing on wounds, which can promote wound healing. It also has the effect of promoting rooting, and finally it can also be applied to buds. This method is widely used in the layering propagation of flowers. First, ring-bark the branch to the phloem, then apply lanolin containing auxin, wrap it with a layer of moist fine soil, and then wrap it with plastic film to prevent water evaporation.
4. Seed dressing and seed coating method
Seed dressing and seed coating are mainly used to treat seeds. Seed dressing means that whether using fungicides, insecticides or micro-fertilizers, we can add an appropriate amount of growth regulators to them. Mix them thoroughly and evenly with the seeds to ensure the surface of the seeds is covered with the agent. You can also use a spray bottle to spray the agent onto the seeds, but you need to stir while spraying. After spraying evenly, sow the seeds. As for seed coating, it uses a special seed coating agent to wrap the seeds, promoting the formation of a film, which can not only improve the germination rate of seeds but also provide pest and disease control effects.
The above is a brief introduction to the application methods of plant growth regulators. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
