不同施肥模式对油菜产量及土壤肥力的影响OA

In order to explore the effects of different fertilization modes on rapeseed yield and soil fer-tility,this paper takes Brassica napus Oleifera Group cv.Youyanzao 18 as the main test material and set up seven'organic+inorganic'fertilization modes to analyze the changes in rapeseed yield and soil fertility under different fertilization modes.The experimental results showed that under the same experimental conditions,when the mixing ratio of organic fertilizer and inorganic fertilizer was 20:80,the yield of rapeseed was the best,and the total nitrogen,total phosphorus,and organic matter content in the soil were significantly higher than other fertilization modes.It can provide some refer-ence and inspiration for the optimization of rapeseed fertilization mode in China.
