Abstract

Abstract:

To evaluate the effects of different slow-control-released fertilizer treatments on wheat yield and economic benefits in Lianshui County, this study established four experimental treatments. The results showed that the SF1 and SF2 treatments of slow-control-released fertilizer improved wheat yield and economic benefits, with the SF1 treatment demonstrating the best performance. The SF1 treatment resulted in the highest maximum tiller number per 667 m², effective panicle number, panicle formation rate, and 1 000-grain weight. The yield of SF1 treatment per 667 m² reached 723.15 kg, representing a significant (p<0.05) increase by 20.51% compared with CK. Economic analysis revealed that the SF1 treatment increased income by 309.0 yuan per 667 m² compared with CK. Comprehensive analysis indicates that the SF1 treatment has significant application effects for wheat cultivation in Lianshui County and possesses high promotion value.

Key words: slow-control-released fertilizer, wheat, yield, economic benefit, Lianshui County
