Abstract: 【Objective】 To provide a theoretical basis for reducing fertilizer application amount of sugar beet after microbial ecological agent applied in seedling bed.【Methods】 The effect of reducing fertilizer application amount on sugar beet plant height,leaf area index,root-shoot ratio,dry matter accumulation,yield and analysis of economic benefit were studied in the semi-arid area of Ulanqab City,Inner Mongolia.【Results】 The results showed that different treatments plant height,leaf area index and dry matter accumulation of sugar beet decreased with the decreasing of fertilizer application in different treatments,the root-shoot ratio had a tendency to decrease first and then increased with the decreasing amount of fertilizer applied.The yield of sugar beet decreased gradually with the decreasing of fertilizer application and the sugar content increased with the decreasing of fertilizer application.【Conclusion】 In the semi-arid area of Inner Mongolia,not only the yield of sugar beet were the highest,but also economic benefit was the highest when the seedbed was treated with 30 kg/hm2 of microbial ecological agent and combined with 750 kg/hm2 of sugar beet fertilizer applied in the field.Compared with conventional fertilization,the fertilizer application amount was reduced by 16.7%.

Key words: Sugar beet, Microbial ecological agent, Reduce the amount of fertilizer applied, Yield, Economic benefit
