Effects of new special fertilizers on physiological activity, biomass and nutrient use efficiency in beans w ere studied.The results show ed that bean biomass increased by 13.02%, 10.25 %and 13.26%with 3 new special fertilizers respectively ;soluble protein content and nitrate reductase activity in leaves and accumula- tion of nutrient in plants increased significantly ;utilizations of nitrogen, phosphate and potassium in- creased by 5.5 % ～7.0%, 0.6 %～1.5%and 4.%～6.1%respectively . ey words:special compound fertilizer;bean;biomass;nutrient use efficiency
