图1 不同氮肥管理下水稻不同时期的茎蘖数 图中不同字母表示在处理间存在显著差异（P<0.05）。图中横坐标上的MT、PI、HD和MA分别表示分蘖中期、穗分化始期、抽穗期和成熟期。下同

Fig. 1 Number of tillers under different nitrogen managements at different growth stages Different lowercase letters indicate significantly different among treatments at 0.05 probability level. MT, PI, HD, and MA stand for mid-tilling, panicle initial, heading, and maturity stages, respectively. The same as below
