Abstract

Abstract: To investigate the effect of microbial ecological agents on growth, yield and quality of sugarbeet in continuous cropping, an experiment was conducted in Linxi county, Inner Mongolia Autonomous Region in 2016. Microbial ecological agent LJT1 was sprayed 3 times in beet seedling bed and LJT3 was sprayed 3 times in transplanting field respectively. Results indicated that spraying microbial ecological agents in seedling bed could significantly increase root length, plant height, plant dry weight and seedling quality, while spraying microbial ecological agents in transplanting field could increase leafSPAD value and photosynthesis ability. It is concluded that the application of microbial ecological agents increases the root yield, sugar content and sugar production of beet. Therefore, in sugarbeet planting, especially in continuous cropping system, micro ecological agents can be used to cultivate strong seedlings, improve the photosynthetic ability, reduce incidence of root rot, and then increase the yield and sugar content.
