Abstract: To study nutrient absorption and utilization of double-low hybrid rape new variety‘Fengyou No.10’ (Brassica napus L.), we conducted a field experiment in the main rapeseed producing area of Henan with ‘Fengyou No.10’as material, and examined the dry matter accumulation in the whole growth period and N, P, K, S and B absorption in different organs at mature stage. The results showed that dry matter accumulation of whole plant showed S-type curve with the growth process, presenting a trend of rapid growth from bolting period to flowering stage, as well as a parabolic relationship (R2=0.9798**) between grain yield and dry matter accumulation in the seedling stage, and a significant linear relationship between grain yield and net increase of dry matter accumulation from flowering stage to mature stage (R2=0.9879**). Both N and P were mostly distributed in grain, which was respectively 73.32% and 75.16% of the total uptake. K content was mainly distributed in stems and pods, and K content in grains took up only 21.31% of the total uptake, S content was mainly distributed in pods and grains, B content of stems and grains was higher, accounting for 69.89% of the total uptake. The amounts of N, P, K, S and B in root were the least, and the distribution ratios were the lowest. Dry matter accumulation both in the upper part and in the whole plant of‘Fengyou No.10’showed a“slowfast-slow”change curve with the growth process. Accumulation of N and P in roots and stems and leaves could be transferred to the grain after flowering. So, sufficient fertilizer supply before flowering stage is the guarantee of high yield.
