图1 氮肥用量对2019/2020和2020/2021年油菜籽粒氮含量的影响 N0、N90、N180、N270、N360表示氮肥施用量为0、90、180、270、360 kg N hm-2。图中小写字母表示相同年份不同氮肥处理间在0.05概率水平差异显著。**表示P < 0.01, ns表示无显著差异。N: 氮肥用量; Y: 不同年份; N×Y: 氮肥用量和年份的交互效应。

Fig. 1 Effects of N application rates on nitrogen content in rapeseed seeds in 2019/2020 and 2020/2021 season N0, N90, N180, N270, and N360 indicate that the N application rate are 0, 90, 180, 270, and 360 kg N hm-2, respectively. Lowercase letters in the same year mean no significant differences at P < 0.05 among the different N fertilizer treatments by LSR test. **: P < 0.01; ns: no significant difference. N: N fertilizer rate; Y: year; N×Y: the interaction of N fertilizer rate and year.
