摘要
为探明杂交早稻组合株两优4024和晚稻组合H优159作双季稻种植的适宜栽培方式,研究了抛秧和移栽2种栽培方式对其剑叶SPAD值、剑叶光合速率、产量及产量构成因素的影响。结果表明,抛栽方式有利于株两优4024和H优159增产;抛栽水稻齐穗后剑叶具有较高的叶绿素含量和光合速率,且下降较缓慢是其高产的生理基础。
To explore the high-yield cultivation methods of Zhuliangyou 4024 and H You 159 when planted as double-cropping rice,the effects of two cultivation methods,i. e.,seedling broadcasting（SB） and transplanting（T）,were studied on SPAD value,photosynthetic rate,grain yield and yield components. The results showed that the seedling broadcasting cultivation was conducive to Zhuliangyou 4024 and H You 159 to obtain higher yield. The higher chlorophyll content and photosynthetic rate and their slower desrease of flag leaf after full heading of the seedling broadcasting cultivation were thought to be the physiological basis of high yield.
