图3 氮肥运筹对不同品种粳稻颖花量的影响(2016-2017) 图中所标注的字母为分化颖花数的显著性, 即实际颖花数、空瘪颖花数与退化颖花数之和。不同字母表示在0.05水平上差异显著。

Fig. 3 Effect of nitrogen application on the flower volume of japonica rice in cultivars (2016-2017) The letters marked in the figure are significant for the number of spikelets, which is the sum of the number of degradation glumous flower, empty glumous flower and practical glumous flower. Different letters above bars stand for significant differences at P < 0.05.
