- Abstract:
- In order to use sewage to irrigate the farmland more scientifically and rationally,sewage from Shaying river was used to irrigate potted soybean with concentration of sewage at 100%，50%，33.3% and 25% respectively.The effects of different diluted sewage irrigation on some physiobiochemical characteristics of soybean seedling and microbes in soybean rhizosphere soil were studied.The results showed that the low concentration treatment of sewage could increase the contents of chlorophyll of soybean and activities of SOD and CAT,and promote the growth of nitrifying bacteria,nitrogenfixing bacteria and cellulose decomposing bacteria,while inhibit denitrifying bacteria and ammonifying bacteria.Sewage with higher concentration could decrease chlorophyll content and SOD,CAT activities,and inhibit the growth of nitrifying bacteria,nitrogen-fixing bacteria and cellulose decomposing bacteria,while stimulate the growth and propagation of denitrifying bacteria and ammonifying bacteria,and promote the accumulation of MDA and permeability of cytoplasm membrane.The promotion effect of sewage was obvious at concentration of 33.3%-50.0%.
