秧苗使用多效唑具有明显的矮化壮秧、早发争穗、增强抗性、防病抑草、增产增收等作用。但若使用不当,会造成秧苗过于矮化、生长停滞甚至死亡、贪青迟熟等不良后果。因此,必须合理使用,才能充分发挥多效唑的效果。1.在水稻育秧上应用多效唑的作用用多效唑培育秧苗,可以省种,一般每亩(1亩=667平方米,下同)杂交稻节省种子0.3~0.5千克;常规稻节省种子3~4千克。并且因多效唑对水稻恶苗病、纹枯病有很好的防治
The use of paclobutrazol seedlings have obvious dwarf strong seedling, early spike, enhance resistance, disease prevention and weeds, increase production and income and so on.

Therefore, we must make rational use of the effect of paclobutrazol. 1. Rice seedling application of paclobutrazol role with paclobutrazolam seedlings, you can save species, the general per acre (1 mu = 667 square meters, the same below) to save seed 0.3 to 0.5 kg of hybrid rice; conventional rice to save seeds 3 to 4 kg . And because of paclobutrazol rice Bakanae disease, sheath blight have a very good control
