Baby vegetable was used as test material,the influence of magnesium potassium sulfate fertilizer on growth characters and yield of them were observed and analyzed. The results showed that magnesium potassium sulfate fertilizer significantly increased the yield,enhanced plant growth,but had little effect on growth stage of baby vegetable.With the increasing of fertilizer application,yield increased.Conventional fertilization +magnesium potassium sulfate fertilizer(K2O)45 kg/hm2as base fertilizer+magnesium potassium sulfate fertilizer(K2O)60 kg/hm2as topdressing at middle growth stage,got the highest yield,increased by 24.13% compared with the control. Considering the factors such as baby vegetable growth,yield and economic benefits,the optimum amount of fertilization was 105 kg/hm2.
