Abstract

Nine combinations of Cd2+ (0,2.5,5mg•L-1) and microbial flocculant (0,10,20mL•L-1) were set, and the hydroponics was adopted in this experiment to explore the effect of microbial flocculant on the rice growth and Cd accumulation under Cd stress, and chlorophyll content, net photosynthetic rate, plant biomass and Cd content in root stem and leaf was determined. The results showed that without Cd stress, adding microbial flocculant could increase the chlorophyll content, promote photosynthesis and plant growth of rice. The inhibition effect of Cd on rice growth was alleviated by adding microbial flocculant. The content of Cd in different organs of rice followed the order: root>stem>dead leaves>fresh leaves. The microbial flocculant inhibited the absorption of Cd2+ by rice root and the transportation of Cd from root to stem and leaf.
