摘　　要：为探究再生稻头季不同收割方式对再生季产量的影响,2023年以福香占为试验材料,头季稻设置机割和手工割2个处理,于再生季成熟期调查穂茎比、农艺性状及产量。结果表明,头季稻采用手工割比机割具有较高的再生季产量和穗茎比,其原因在于手工割的再生季有较多的有效穗数、穗粒数;手工割的收割费用比机割高,经济效益比机割少。因此,头季采用机割不仅有利于减少农村劳动力不足的矛盾,而且能提高再生季的经济效益。In order to investigate the effect of different harvesting methods on the main-season yield of ratoon-crop rice,two treatments were set in 2023 using Fuxiangzhan as material:machine cutting and manual cutting.The number ratio of effective panicle to stubble stem(RPS),agronomic traits,and yield were investigated.The results showed that compared to machine cutting,manual cutting had higher average RPS and yield,because of manual cutting had more effective panicle number.Manual cutting also had higher harvesting cost and lower economic benefits than machine cutting.Therefore,machine cutting of main-crop season not only helped to reduce the contradiction of rural labor shortage,but also provided a scientific basis for the mechanized production of ratooning rice.
