图2 2018年和2019年“独秆”栽培模式下全程氮肥在分蘖中后期施用对旱直播水稻产量的影响 N1: 180 kg N hm-2; N2: 225 kg N hm-2; L6、L7、L8、L9、L10分别为六、七、八、九和十叶龄期5个追肥叶龄期。不同小写字母表示在0.05水平差异显著(LSD法)。

Fig. 2 Effects of nitrogen fertilizer in whole growth duration applied in the middle and late tillering stage on yield of dry direct seed rice under “solo-stalk” cultivation mode in 2018 and 2019 N1: 180 kg N hm-2; N2: 225 kg N hm-2; L6, L7, L8, L9, and L10 are the five topdressing leaf ages of 6, 7, 8, 9, and 10, respectively. Different lowercase letters indicate significant differences at the 0.05 probability level by LSD test.
