However, plant growth regulators are organic compounds that are artificially synthesized or naturally extracted. They are applied to plants from the outside, and they have the activity of plant hormones at relatively low concentrations; they regulate plant growth, change the development schedule, and increase the fruit setting rate and fruit weight. Increase production and increase income. Many types of plant growth regulators have different effects. Such as indole butyric acid, α-naphthylacetic acid, 2,4-D and other auxins, mainly used for cutting seedlings, promote rooting, prevent flowering and fruit drop, promote fruiting; gibberellin class regulators can promote cell elongation, prevent Formation of layers, breaking of dormancy of tubers and bulbs, etc., can also induce flowering, increase fruit setting and parthenocarpy in some plants; cytokinins such as kinetin mainly promote cell division, induce bud differentiation, inhibit organ aging and increase fruit set. And improve fruit quality; ethephon production in the main role is to ripen the fruit, promote flowering and female flower differentiation, promote detachment, promote the secretion of secondary biomass, etc.; ethylene inhibitors reduce fruit shedding, inhibit fruit ripening, extend fruit and Cut flowers fresh life; chlormequat, paclobutrazol, uniconazole, longer than the rest is a plant growth retardant, can make the internode shortening, compact plant type, to prevent lodging; brassinolide can promote crop growth, improve seeds Germination rate, increase crop yield, and increase crop resistance. To use plant growth regulators, first of all make it clear that they are not nutrients and cannot substitute for fertilization. It only regulates the growth of plants through the influence of hormones and physiological processes in plants, which is different from trace element fertilizers. When the plant's nutritional status is not good, it is useless to use hormones. On the other hand, the application of growth regulators is only an auxiliary measure and can only play a regulatory role on the basis of reasonable cultivation and management. If it is to prevent the lodging of wheat, it can be soaked with Chlormequat, and proper close planting and balanced fertilization are still the main measures. The second is that good things cannot be used indiscriminately or abused. Different growth regulators have special effects and specific use time. They can not increase the concentration, increase the dose, and increase the number of uses. Its technical requirements are very strict. Improper use can also result in reduced production and quality. Therefore, it must be selected when using, and it can be used according to the instructions in order to achieve the desired effect.

Rational use of plant growth regulators
Plant growth regulators can break dormancy and promote germination; increase pods and roots, cultivate short-sturdy seedlings; promote grain filling and enrichment; control leggy and prevent fall; prevent falling flowers and fruit, promote fruitfulness, and promote maturity.
