A hydroponic experiment was employed to study the effects of molybdenum addition on the growth and germination of mung bean.The results indicated that the nutrient solution with 0.3 mg/L of Mo6+could stimulate the seed germination and promote the growth of plants,at the same time,all kinds of indicators were the best.With the increase of Mo6+concentration,seed germination and seedling growth were restrained.And with the increase of the concentration,inhibitory effect gradually increased.When the concentration of Mo6+was 247.4 mg/L,seedling height was 55.53 % lower than the control group and the root length was 84.19 % lower than the control group.The inhibition of other indicators was signifi-cantly enhanced. The appropriate levels of molybdenum is the necessary trace element in animals and plants.Excessive molybdenum will cause serious damage to the growth and development of animals and plants.
