How to use plant growth regulators is wrong?

How to use plant growth regulators is wrong? Why is this wrong? Experienced netizens are also asked to help introduce plant growth regulators, which are mainly exogenous non-nutritive chemicals, which can usually be transmitted to the active site in the plant, and can promote or inhibit some aspects of its life process at a very low concentration. To make it meet the needs of human beings. Because each plant growth regulator has a specific use, and the application technical requirements are very strict, it can have a specific effect on the target plant only under specific application conditions (including external factors). Often the opposite result can be obtained by changing the concentration, for example, it has a promoting effect at low concentration and an inhibitory effect at high concentration. However, in the process of visiting the countryside, many farmers have some obvious misunderstandings in the use of plant growth regulators, which seriously affect the effect of use. Therefore, the farming network collates the common misunderstandings in the use of plant growth regulators, which are listed below for netizens' reference. First, replace "fertilizer" with "agent": because plant growth regulators can play a significant role only under sufficient water and fertilizer conditions, but some plant growth regulators are exaggerated by manufacturers, resulting in some farmers using them as fertilizers and pinning their hopes on plant growth regulators rather than on conventional techniques such as fertilization, irrigation, ploughing and loosening soil. Finally, it affects the effect of plant growth regulators. Second, increase the amount of plant growth regulators at will: because plant growth regulators belong to hormone substances, the general dosage per mu is only a few grams or a few milliliters. 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. Third, directly use some plant growth regulators for water: for example, 92 ○ (gibberellin), which is widely used in production, must be dissolved in alcohol or warm spirits before water can be used. However, before using plant growth regulators, some farmers often do not read the instructions carefully, but use plant growth regulators directly to 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. Fourth, mix with other substances at will: for example, 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". Fifth, spray plant growth regulators at will: plant growth regulators must be used at the critical time of plant growth (such as cucumber flower bud differentiation) 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.
