Methods of using plant growth regulators

Plant growth regulator is a kind of pesticide commonly used in our planting and production. Rational use of plant growth regulators can effectively enhance crop growth ability and improve crop yield and quality. But many people don't know how to use plant growth regulators. So the editor brings you how to use plant growth regulators today. Let's take a look at it.

1. Solution spraying

Solution spraying is the most commonly used method of plant growth regulators. First of all, we should prepare the liquid according to the concentration requirements, and then spray it. When spraying, the liquid should be small, evenly sprayed and the spraying site should be moist. At the same time, in order to ensure that the solution can be well attached to the plant, an appropriate amount of emulsifier can be added, such as washing powder or some surfactants and so on. In order to improve the adhesion of the agent, at the same time, when we spray, we should pay attention to spray it on the action site.

2. Immersion method

Soaking is mainly used in the cutting propagation of crops and to improve the rooting rate of cuttings. At the same time, it can also be used to treat seeds, accelerate fruit ripening and so on. For example, for some woody cuttings with leaves, we can soak them in indole butyric acid for about 10-20 hours, and then insert them directly into the seedbed. There is also a quick dip in the lack of roots, use naphthalene acetic acid and talc powder to mix, and then soak the lower part of the cuttings, and then dip an appropriate amount of powder into the seedbed.

3. Smear method

Smearing is the application of plant growth regulators to a part of the crop. One of the commonly used lanolin and so on, there will be drugs directly smeared lanolin in the need to deal with the place, generally mainly to the wound, can promote wound healing. At the same time, it also has the role of promoting rooting, and finally can be smeared on the buds. This method is widely used in flower striping propagation. First cut the phloem around the branch, and then apply lanolin containing auxin to cover a layer of moist fine soil. Then wrap it in a thin film to prevent the water from evaporating.

4. Mix all kinds of clothes

Seed dressing and seed coating are mainly used to treat seeds. Seed dressing means that whether we use germicidal pesticides or micro-fertilizers, we can add the right amount of growth regulators to it. Mix it well with the seed to ensure that the seed is stained with medicine. You can also use a spray can to spray the seeds, but you need to stir and spray, spray evenly and sow the seeds. As for seed coating, it is to use a special dosage form of seed coating agent to wrap it around the seed to form a thin film, which can not only improve the seed germination rate, but also play the effect of pest control.

The above is a brief introduction to the use of plant growth regulators. That's all for today's introduction. This article is for reference only. I hope it can help you all.
