1. Improve nitrogen fixation ability
DA-6 (Diethyl aminoethyl hexanoate):
Soak the seeds with DA-6 at a concentration of 8-15 mg/L for 8 hours, and spray once at the beginning of flowering and pod-setting stages of the seedling stage to achieve the effects of improving germination rate, increasing the number of flowers, improving the nitrogen fixation ability of rhizobia, plump pods, increased dry matter, early maturity, and increased yield.

S-abscisic acid is mixed with fertilizer to increase the number of cotton seedling roots, enhance the stress resistance of cotton seedlings, and strengthen the seedlings.

Trinexapac-ethyl is a gibberellins biosynthesis inhibitor. Its main function is to control the vigorous growth of crops by reducing the content of gibberellins in plants, thereby achieving the purpose of controlling vigorous growth and resisting lodging.

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.
