摘要: 【目的】 为苗床施用微生态制剂后甜菜减少化肥施用量提供理论依据。【方法】 在内蒙古乌兰察布市半干旱地区研究了减少化肥施用量对甜菜株高、叶面积指数、根冠比、单株干物质量和产量的影响,并进行经济效益分析。【结果】 不同处理甜菜株高、叶面积指数和单株干物质量随施肥量的减少而降低,植株根冠比随施肥量的减少呈先降低后增加的趋势;甜菜产量随施肥量的减少呈逐渐降低的趋势,含糖率随施肥量的减少呈逐渐增加的趋势。【结论】 在内蒙古半干旱地区,甜菜纸筒育苗施苗床微生态制剂30 kg/hm2,配合专用肥750 kg/hm2,甜菜不仅产量最高,而且经济效益最高,与常规施肥相比,施肥量减少了16.7%。

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
