This study aims to enhance crop yield and quality,optimize fertilizer utilization,mitigate non-point source pollution in agriculture,elevate the quality of cultivated land,and promote high yield and high-quality culti-vation of crops.The research investigated the effects of six different types of fertilizers on rice yield and quality in order to identify the most suitable fertilizer varieties for rice cultivation in the Chaohu Lake Basin,so as to form a large-area application model.Different fertilizer varieties were set up by completely random block design,and six fertilizer treatments were tested in the field with no fertilization (CK),conventional fertilization (CF),controlled loss fertilizer (T1),slow controlled release fertilizer (T2),rice special fertilizer (T3) and humic acid compound fertilizer (T4).The rice yield,quality and nitrogen fertilizer utilization were analyzed at maturity.The results indicated that compared to the CF,the yield and quality of rice were significantly improved,the yield of T1 rice was 10453.95 kg·hm-2,while the yield of humic acid compound fertilizer increased by 16.4% and 13.3% compared with CK and CF,respectively.The nitrogen fertilizer utilization rate of controlled fertilizer was the highest,reaching 48.57%.In terms of rice quality,the overall taste quality of CK was significantly lower than that of other treatments,and the treatment with the highest protein content was in T4.Synergistic control of loss and humic acid compound fertilizer can significantly improve rice yield and quality,among which the low price of humic acid compound fertilizer is conducive to saving costs and improving economic benefits.
