Abstract: | In order to explore the application effect of carbonaceous humic acid fertilizer on fertile oranges, through field experiments, the effect of Tanlisu humic fertilizer on the yield and quality of citrus was studied. The results showed that the Tanlisu humic fertilizer had obvious effects on the growth traits, yield and quality of the citrus. After applying c Tanlisu humic fertilizer, many physiological indicators of citrus have been significantly improved, such as leaf thickness, chlorophyll value, fruit size, fruit diameter, etc., and it has a significant effect on increasing yield, and the sugar content and taste of the fruit have been significantly improved. Therefore, Tanlisu humic fertilizer can effectively increase the yield and quality of citrus, and can greatly increase the economic benefits of citrus. |
