The results were showed as follows:panicle fertilizer was applied at 1.5 leaves from top(LFT),2.5 and 0.5 LFT,and 3.5,2.5 and 1.5 LFT could increase the chlorophyll and nitrogen content of higher effective leaves,and thus increased the rice yield.

• 结果表明 :倒 1 5叶 ,倒 2 5和 0 5叶 ,倒 3 5、 2 5和 1 5叶施肥提高了花后高效叶片叶绿素含量和含氮率。
