Abstract:
In this paper, a pot culture experiment was conducted to study the effect of different concentration of nodule growth-promoting agent(NGPA) on the variation of dry weight(DW),nodule number,root vigor,nitrogenase activity and leghemoglobin in nodule of soybean(Glycine max L.)at seedling, flowering and podding stage. The results showed that moderate concentration of NGPA promoted various physiological indexes of soybean. Higher concentration of NGPA significantly inhibited soybean growth and development, nodulation and nutrition absorption function, etc.Among all the treatments, T3(0.143% v/v) of NGPA) performed best compared to the other four NGPA concentrations. T1(CK) and T4(0.286% of NGPA) had same effect on nitrogenase activity and leghemoglobin content. Proper application of NGPA demonstrated significant effects in the early growth stage of soybean. In order to reduce the use of chemical nitrogen fertilizer, protect the ecological environment and promote sustainable agricultural development, the establishment detection system of the NGPA on nodule growth-promoting would play an important role.
