不同氮磷钾配比对长优2号水稻产量和经济性状的影响

Effect of N,P,K Ratio on Yield and Economic Characters of Changyou 2

采用"3414"方案设计试验,研究不同氮磷钾配比施肥对长优2号水稻产量及经济性状的影响。结果表明,氮、磷、钾肥对长优2号都有一定的增产效应,其中以氮肥的增产效应最为显著,磷肥与钾肥次之。初步得出本次试验最佳施肥量为纯N 243.45 kg/hm^2、P2O5126.90 kg/hm^2、K2O 240.90 kg/hm^2,N、P2O5、K2O比接近1.0∶0.5∶1.0水平。

The experiment of"3414"design was carried out to study the effect of different ratios of N,P and K fertilization on the yield and economic characters of Changyou 2.The results showed that N,P and K all had a certain yield-increasing effect on Changyou 2,among which,the effect of N was the most significant,followed by that of P and K.It is preliminarily concluded that the best fertilization amount in this experiment was N243.45 kg/hm^2,P2O5126.90 kg/hm^2,K2O 240.90 kg/hm^2,and ratio of N,P and K was close to 1.0∶0.5∶1.0.
