Study on the effect of spraying plant growth regulators trinexapac-ethyl and brassinolide on sugarcane growth

Objective:
To explore the effect of spraying trinexapac-ethyl and brassinolide on sugarcane growth and provide data support for increasing sugarcane yield.

Method:
Trinexapac-ethyl and brassinolide were made into ultra-low volume preparations, and single-rotor ultra-low volume spray aircraft was used to spray sugarcane at the early stage of tillering.

During the experiment, various physiological parameters of sugarcane in the test field were measured, including tillering rate, plant height, stem diameter, and effective stem number per mu, and finally its theoretical yield was calculated.

Conclusion:
Spraying the compound preparation of trinexapac-ethyl and brassinolide on sugarcane at the early stage of tillering has a significant promoting effect on sugarcane yield.
