To investigate the regulatory effects of mixed application of 3% diethyl aminoethyl hexanoate · 27% ethephon and zinc sulfate on summer maize, Hanyu 398 was used as the experimental material. 5 fertilization treatments were set up: F0 (no fertilization), F1 (conventional compound fertilizer), F2 (sulfur-coated slow/controlled-release compound fertilizer), F3 (urea-formaldehyde slow/controlled-release compound fertilizer), and F4 (polymer-coated slow/controlled-release compound fertilizer). 3 spray treatments were applied: P0 (spraying with clear water), P1 (spraying with 3% diethyl aminoethyl hexanoate·27% ethephon), and P2 (spraying with 3% diethyl aminoethyl hexanoate·27% ethephon + zinc sulfate). The effects of each treatment on plant traits, ear traits, and yield of summer maize were analyzed. The results showed that, across all fertilization treatments, compared with P0, P1 reduced plant height, ear height, 1000-kernel weight, and kernel number per ear by 3.0-14.6 cm, 3.0-12.3 cm, 2.5-15.0 g, and 3.1-59.5 grains, respectively, while yield was reduced by 1.5%-18.9%. In contrast, compared with P1, P2 increased plant height, ear height, 1000-kernel weight, and kernel number per ear by 1.0-14.5 cm, 1.5-10.5 cm, 0.5-16.0 g, and 4.4-40.8 grains, respectively, while yield was increased by 1.2%-17.9%. In conclusion, it was demonstrated that the combined application of 3% diethyl aminoethyl hexanoate·27% ethephon and zinc sulfate could achieve better chemical control effects in maize cultivation.
