摘　　要：研究不同插秧期对禾田稻2号产量影响,结果表明,随着插秧时间的延迟,水稻生育期减少,水稻的总叶片数减少,产量构成因素有效穗数、每穗粒数及结实率表现降低的趋势;处理1实收产量最高,产量为667.0kg/667 m^(2),处理2产量次之,产量650.3 kg/667 m^(2),处理3产量最低,产量630.3 kg/667 m^(2)。The effect of different transplanting periods on the yield of Hetiandao-2 was studied.The results showed that with the delay of transplanting time,the growth period of rice decreased,the total number of leaves of rice decreased,and the effective panicle number,grain number per panicle and seed setting rate of yield components decreased.The yield of treatment 1 was the highest(667.0 kg/667 m^(2)),the yield of treatment 2 was the second(650.3 kg/667 m^(2)),and the yield of treatment 3 was the lowest(630.3 kg/667 m^(2)).
