Effects of commercial organic fertilizer combined with chemical fertilizer on the growth of Brassica napus and soil physical and chemical properties
In order to explore the effects of the combination of commercial organic fertilizer and chemical fertilizer on the growth of Brassica napus and soil physicochemical properties in Brassica napus production,this study conducted field experiments and analyzed the effects of different proportions of commercial organic fertilizer combined with chemical fertilizer on Brassica napus emergence,growth period,agronomic traits,yield,and soil physicochemical properties by setting up no fertilization treatment,full chemical fertilizer fertilization treatment,and 5 different proportions of commercial organic fertilizer replacing chemical fertilizer treatment.The results showed that compared with full chemical fertilizer application,different proportions of commercial organic fertilizer combined with chemical fertilizer were beneficial for promoting the growth of Brassica napus,increasing the number of mature plants by 7.41％to 37.04％,shortening the growth period by 7-17 days,performing better in agronomic traits,and increasing yield by 14.38％to 27.94％;The soil organic matter and available potassium content of different proportions of commercial organic fertilizers combined with chemical fertilizers have been improved compared to full chemical fertilizer fertilization,and the soil structure stability is better.Overall,the combination of 60％commercial organic fertilizer and 40％chemical fertilizer is beneficial for the growth of Brassica napus,improves soil fertility,and provides a reference for reducing and increasing the efficiency of chemical fertilizers in Brassica napus production.
