摘要
为探明常规育苗、托盘育苗和漂浮育苗3种方式对水稻育苗及大田生长的影响,以‘南粳9108’为供试材料,比较相同播量下3种方式所育秧苗素质差异及对栽插质量、大田生长和产量的影响。结果表明:3种育苗方式成苗率在71.7%-75.0%,其中漂浮育苗最高,三者的地上部性状无显著差异,但常规育苗根系数量及长度较托盘育苗和漂浮育苗分别增加21.4%、16.1%和3.3%、9.8%;漂浮育苗的空穴率和伤秧率分别为0.39%、0.78%,栽插质量最优;漂浮育苗分蘖高峰期分蘖数较托盘育苗和常规育苗分别增加9.8%和24.0%,但单株生物量积累有所降低;漂浮育秧最终成穗数较托盘育苗、常规育苗增加7.2%和8.1%,但每穗实粒数降低4.9%、4.6%,在最终产量上三者之间无显著差异。综合来看,3种育苗方式都可育出健壮秧苗,并且栽插质量、大田生长和产量表现良好,在生产上可根据实际情况进行选择。
To investigate the effects of conventional seedling cultivation,tray seedling cultivation,and floating seedling cultivation on rice seedlings and field growth,Nanjing 9108'was used as the experimental material,and the differences in seedling quality and their effects on transplanting quality,field growth,and yield were compared among the three methods under the same sowing amount.The results showed that the seedling formation rates of the three seedling cultivation methods ranged from 71.7%to 75.0%,among which floating seedling had the highest rate.There was no significant difference in aboveground traits among the three methods.However,the number and length of roots in conventional seedling cultivation increased by 21.4%,16.1%and 3.3%,9.8%compared to tray seedling cultivation and floating seedling cultivation,respectively.The void rate and damaged seedling rate of floating seedling cultivation were 0.39%and 0.78%,respectively.During the peak tillering period of floating seedling cultivation,the number of tillers increased by 9.8%and 24.0%respectively compared to tray seedling cultivation and conventional seedling cultivation,but the accumulation of biomass perplant decreased.The final number of panicles in floating seedling cultivation increased by 7.2%and 8.1%compared to tray seedling cultivation and conventional seedling cultivation,but the number of grains per panicle decreased by 4.9%and 4.6%,respectively.There was no significant difference in final yield among the three seedling cultivations.Overall,all three seedling cultivation methods could produce robust seedlings,which were beneficial to improve the planting quality,field growth,and yield performance.In terms of production,suitable seedling cultivation methods could be selected according to their own conditions.
