Application of Baiheyuan Gibberellin in Sugarcane Production

Gibberellin is a widely occurring class of plant hormones. Its chemical structure belongs to diterpenoid acids and is derived from a tetracyclic skeleton. It stimulates the growth of leaves and buds. There are at least 38 known gibberellins. Gibberellin is used in agricultural production and has good effects in some aspects.
The following is a brief introduction to Baiheyuan Xiaobian for the application of Baiheyuan gibberellin in sugarcane production:
Promote the growth of sugar cane sugar: gibberellin can regulate the physiological function of sugar cane and improve the carbon to nitrogen ratio of plants. Sugarcane using gibberellin, sugarcane leaves increased significantly, leaf color deepened, leaf area expanded, leaf population density increased, photosynthesis efficiency was improved, sugarcane stem growth was accelerated, and sugar-increasing effect was remarkable. The sugarcane edible stems using gibberellin increased by 10-15 cm, the plant height increased by more than 15%, the internode growth increased by 18%-20%, and the yield increased by 15%-20%. It has been determined that the sugar content of sugar cane is increased by about 5% compared with the control. At present, the use of gibberellin technology in sugar cane has been widely applied.
At the end of the sugarcane tillering to the early stage of jointing, the gibberellin 40-50mg/L liquid is 25-30kg per 667m2, and then sprayed once every 15d for 2-3 times. Generally, it can be sprayed 1-2 times on the initial sugarcane field with better fertility; for the fertility, the field of sugarcane planted for many years should be sprayed 3 times.
Promote the growth of sugarcane stems and leaves: The use of gibberellin in sugar cane can promote the growth of stems and leaves, but the increase in concentration does not increase the growth effect, so it is necessary to control the concentration. Increasing the application of fertilizer once 7 days before spraying gibberellin increased the yield significantly. It can be mixed with 2% potassium dihydrogen phosphate in gibberellin solution and applied with nitrogen, phosphorus and potassium quick-acting fertilizers. Pay special attention to the application of potassium fertilizer. Be sure to apply the medicine when the weather is fine.
