Plant growth regulators can effectively regulate the growth process of crops in agricultural production, so as to achieve the effects of stable production, increase production, improve quality and enhance crop stress resistance. Therefore, agriculture is widely used, and there are many commonly used drugs, which can regulate the growth of plants. But every coin has two sides.
Plant growth regulator--chlormequat chloride
Plant growth regulators inhibit the vegetative growth of plants (the growth of aboveground parts such as stems, leaves and branches), promote reproductive growth (the expansion of underground parts such as fruits and stems), prevent and control plants from growing too long and too long, play the role of dwarfing plants, shortening internodes, and improving stress resistance, so that crops can blossom more, bear more fruits, tillers more, pods more, branches more, increase the content of chlorophyll and enhance the brightness. It has a very good effect of controlling length and increasing production.
Chlormequat chloride is mainly used in flowering and fruiting period, and is often used in crops with short growth period, such as cotton, wheat, corn, rice, sorghum, peanut, soybean, tomato, cucumber, potato, sugarcane, apple, pear, peach, grape, orange, etc.
The compound of chlormequat chloride
Compound of plant growth regulator and fertilizer
Chlormequat chloride + boric acid
The application of the mixture in grape can overcome the deficiency of chlormequat chloride. The experiment shows that spraying the whole plant with certain concentration of chlormequat chloride 15 days before flowering can greatly improve the yield of grape, but reduce the sugar content of grape juice. The mixture can not only play the role of auxin in controlling fruit growth and increasing fruit yield, but also overcome the side effect of reducing sugar content after the use of auxin.
Compounding technology of other plant growth regulators
Inhibiting fruit setting agent and grain yield increasing agent: their functions are to control vigorous growth and improve fruit setting rate.
Other types: chlormequat chlorid + Ethrel, chlormequat chlorid+ abscisic acid, chlormequat chlorid + Ethrel + copper sulfate,chlormequat chlorid + pyrimidinol, chlormequat chlorid + gibberellin, abscisic acid + gibberellin, etc.
