Plant growth regulators, which are synthetic (or natural ones extracted from microorganisms), are organic compounds with similar effects of natural plant hormones on growth and development. What misunderstandings are easy to occur in the use of plant regulators?

Introduction to the use of regulators in plants

After people understand the structure and action mechanism of natural plant hormones, plant growth regulators are used in agricultural production through artificial synthesis of substances with similar physiological and biological effects to plant hormones, so as to effectively regulate the growth process of crops. to achieve the purpose of stabilizing yield and increasing production, improving quality, enhancing crop resistance and so on.

Plant growth regulators are synthetic chemicals that regulate the growth and development of plants and natural plant hormones extracted from organisms. It's called plant growth regulator. The common plant growth regulators are DA-6, clopirazide, sodium nitrophenol, brassin and gibberellin.

Second, what misunderstandings are easy to occur in the use of plant regulators?

1. Do not use fertilizer after using plant regulators.

Plant growth regulators can play a significant role only under sufficient water and fertilizer conditions, but some plant growth regulators have been exaggerated by manufacturers, causing some farmers to use them as fertilizers. Pinning the hope of promoting crop growth on plant growth regulators, instead of working on conventional techniques such as fertilization, irrigation, ploughing and loosening soil, will eventually affect the use of plant growth regulators.

2. Do not misuse according to the specific conditions of plant growth.

Plant growth regulators must be used at the critical time of plant growth in order to maximize their effectiveness. If you use it at the wrong time, you will not be able to get the desired effect, and even produce "side effects". Some farmers do not have enough understanding of this, and think that whenever plant growth regulators are sprayed, they can promote growth, increase production, and increase income. therefore, regardless of the timing, spraying at any time leads to poor effect of spraying, and some even reduce production and income.

3. Misuse of quantity

Plant growth regulators belong to hormone substances, which generally require only a few grams or a few milliliters per mu. However, some farmers are always afraid that the less dosage will not have any effect, and they will increase the dosage or concentration of plant growth regulators at will, which not only can not promote plant growth, but will inhibit its growth, even lead to leaf deformity, dry shedding and death of the whole plant.

4. Mixed with other drugs and fertilizers

Whether plant growth regulators can be mixed with chemical fertilizers, pesticides and other substances can only be determined after careful reading of the instructions and experiments. However, many farmers use plant growth regulators to save trouble and often mix them with chemical fertilizers, pesticides and fungicides at will, hoping to promote growth or protect flowers and fruits, supplement fertilizers or prevent diseases and pests at the same time. However, if the mixture is not appropriate, it will "get half the result with twice the effort", or even "work in vain".

5. Do not follow the instructions

If a gibberellin is widely used in production, it must be dissolved with alcohol or warm height liquor before it can be used with water. However, some farmers often do not read the instructions carefully before using plant growth regulators, but use plant growth regulators directly with water. Because some plant growth regulators can not be directly dissolved in water, and if a small amount of plant growth regulators are not prepared in advance into a "mother solution" and then prepared into the required concentration, it is difficult to mix at one time, which will also affect the effect of use.
