选择双季不同生育期的早、晚稻各8个品种，采用等行和宽窄行2种机插方式，探讨了2种机插方式下双季稻不同品种的产量和主要生理性状表现，旨在为双季稻机插的品种选择和适宜机插方式提供参考。结果表明，宽窄行机插处理较等行机插处理，早晚稻产量各提高2.90%和2.73%；宽窄行机插处理叶面积指数高于行机处理；宽窄行机插处理平均光合势高于等行机插处理，从分蘖盛期到成熟期各生育阶段，早稻分别提高了0.92%、3.99%、5.64%，晚稻分别提高了3.46%、7.09%、6.79%；宽窄行机插处的叶绿素 SPAD值、根系活力高于等行机插处理；宽窄行机插处的单穗枝梗和颖花分化数较高、退化率较低。同等机插条件下，早稻品种株两优819和晚稻品种丰源优299有明显的产量优势，此类品种可作为江西等双季稻区机插品种首选。

The research selected 16 rice varieties (8 early and 8 late double-cropping rice) by mechanical transplanting modes as per equivalent row and wide-narrow row to explore yield and physiological traits in order to provide references for selection of rice variety suitable for mechanical transplanting. The results showed that yields of early and late rice improved by 2.90% and 2.73% by mechanical transplanting as per equivalent row and wide-narrow row respectively. Besides, leaf area index in the treatment as per wide-narrow row was higher compared with the treatment as per equivalent row, as wel as average photosynthetic potential which grew by 0.92%, 3.99% and 5.64% of early from til ering-peak stage to mature stage and 3.46%, 7.09% and 6.79% of late rice. Furthermore, by mechanical transplanting as per wide-narrow row, SPAD value, and root activity performer higher, as wel as the number of differentiated branch and glumous flowers, but degradation rate showed lower. In addition, with mechanical transplanting the same, early rice Zhuliangyou 819 and late rice Fengyuanyou 299 took advantages in yield, which can be priori-ties for mechanical transplanting in double-cropping areas in Jiangxi Province.
