摘要
以龙粳31为试验材料,通过毯式育秧方式,研究3种水稻壮秧剂对机插秧秧苗素质的影响。结果表明:“尼亚”、“机插宝”和“壮家宝”壮秧剂与对照相比,能够降低株高、增加茎基宽、增加白根数、增加地上重量、根系重量,提高秧苗充实度和出苗率。3种壮秧剂能够提高机插秧秧苗素质,延长秧龄,同时“机插宝”施用量和成本较低,值得推广应用。
The japonica rice Longgeng-31 was used to carry out the plot experiments of seedling breeding with blanket shaped seedling tray,and the effects of three kinds of seedling strengthen agents on the quality of the mechanically-transplanted rice seedlings were studied.The results showed that:in comparison with the control,the seedling strengthen agents"Niya","Zhuangjiabao"and"Jichabao"could reduce the seedling height,increase the basal stem width,the number of white roots,root weight,shoot weight,improve the rice plumpness and emergence rate.Three kinds of seedling strengthen agents could improve the quality of rice seedlings,and extend the seedling age,"Jichabao"seedling strengthen agent reduced the amount of application and cost,thus it was worthy of popularizing and applying.
