In view of the phenomenon of excessive fertilizer application with low efficacy in rice production, we conducted a trial of appling rice with Strongreen, which is a biomass micromolecule organic carbon fertilizer and can improving rhizosphere biodiversity, in reducing chemical fertilizer amounts and increasing fertilizers efficiency. The results showed that applying Strongreen and no reduced conventional fertilizer can increase rice yield by 7.8%, and applying Strongreen and reduced conventional fertilizer can obtain equivalent rice yield compared with the conventional fertilization, but it can avoid the waste of chemical fertilizer and slow down the agricultural nonpoint source pollution. Applying Strongreen in both cases can improve rice root activity and increase chlorophyll content and effective panicles.
