[Method] Four treatments including different types of fertilizers were set in the test. Growth, photosynthesis and chlorophyll fluorescence parameters at flowering stage such as plant height, stem diameter, shoot and root dry matter, net photosynthesis, light energy conversion effi- ciency (Fv/Fm) and SPAD value, were investigated. The effects of fertilizer treat-ments on the yield of rapeseed were evaluated as well. [Result] Both multi-functional fertilizer and controlled release fertilizer could improve plant height, stem diameter, shoot dry matter, SPAD value, net photosynthesis, non-photochemical quenching (NPQ), etc., which helped increase yield and stress resistance. [Conclusion] Both multi-functional fertilizer and controlled release fertilizer could improve yield significantly while multi-functional fertilizer (MFF) was better than controlled release fertilizer (CRF).展开更多
