Abstract:

Potassium humate fertilizer can increase the content of available potassium of soil, which has the functions of improving soil, promoting crop growth, improving crop stress resistance, improving crop quality, protecting agricultural ecological environment and so on. In this study, conventional maize special fertilizer and potassium humate compound fertilizer were used as the control and treatment. After application, the factors such as soil improvement, fertility, growth, production, quality and planting cost were analyzed. The results showed that the treatment was better than control in soil improvement and fertility cultivation. Compared with the control, the treatment of vegetative growth stage could significantly promote the stalk thickening and lay a good foundation for the lodging resistance of maize. The treatment at the reproductive growth stage of maize significantly promoted ear weight, core weight, grain weight per ear and plot yield. The content of protein, starch, dry matter and reducing sugar of maize were improved slightly, but did not reach significant difference level. In terms of cost, potassium humate compound fertilizer increased maize yield by 22.6% and the yield per hectare increased income by 3918 yuan (29.6%). The results demonstrated that the application of potassium humate compound fertilizer had a good effect on improving soil, fertilizing soil capacity, promoting maize yield and quality, and increasing income, providing reference for high-yield crops and environment-friendly fertilization methods.

Key words: potassium humate compound fertilizer, maize, cultivate a fertile soil, improve quality and efficiency
