图5 缓控释肥处理下水稻产量构成因素与剑叶碳氮代谢关键酶活的相关性分析 Y：产量，TNS：总颖花量，GW：粒重。7DAA、21DAA、35DAA分别表示花后7 d（灌浆前期）、21 d（灌浆中期）和35 d（灌浆后期）。

Fig.5 Correlation analysis between yield components and key enzyme activities of carbon and nitrogen metabolism in flag leaves of rice Y; yield, TNS: total number of spikelets, GW: grain weight. 7DAA, 21DAA, and 35DAA represent 7 (early grain filling), 21 (mid-grain filling), and 35 (late grain filling) days after anthesis, respectively. *: P < 0.05, **: P < 0.01.
