Abstract:
The present study was carried out to explore the response of nitrogen and phosphorus fertilizer on nodulation and plant growth of soybean.Nodule number,nodule weight,shoot height,shoot biomass,root biomass and pod number of soybean were examined by pot experiment in green house under three nitrogen fertilizer(0,200 and 500 mg·kg-1)and three phosphorus fertilizer(0,200 and 500 mg·kg-1)usage.The result showed that the influence of nitrogen and phosphorus fertilizer on nodule number and weight was similar.Above 200 mg·kg-1 nitrogen fertilizer usage significantly inhibited nodulation.Phosphorus fertilizer promoted nodulation and relieved the inhibitory effect caused by nitrogen fertilizer.Plant growth of soybean was promoted by nitrogen and phosphorus fertilizer.Shoot biomass and pod number were greatly increased by combination of 200 mg·kg-1 phosphorus fertilizer and 500 mg·kg-1 nitrogen fertilizer.Root biomass of soybean was the highest by only 500 mg·kg-1 nitrogen fertilizer application.In a word,increasing phosphorus fertilizer could improve nodulation and plant growth of soybean simultaneously.While nitrogen fertilizer inhibited nodulation of soybean regardless of phosphorus usage modification.
