进行了小麦起身期喷施矮壮丰、壮丰安的试验研究。结果表明:在小麦起身(期倒5叶)喷施矮壮丰750ml/hm2、壮丰安525ml/hm2,均可有效地抑制基部节间伸长,使植株矮化,茎基部粗硬,增强抗倒伏能力。喷施矮壮丰和壮丰安均有增产效应,其中喷施矮壮丰750 ml/hm2增产效果最好,增产达6.2%。揭示了矮壮丰、壮丰安对小麦群体质量的调控效应及防倒增产机理。 The wheat was sprayed during the onset of short Zhuang Feng, Zhuang Feng An experimental study. The results showed that when the wheat was up (down 5 leaves), the short and strong Feng 750ml / hm2 and the strong Feng’an 525ml / hm2 were sprayed, all of which could effectively inhibit the elongation of the basal internodes, dwarf the plants, Anti-lodging ability. Spraying short Zhuang Feng and Zhuang Feng Ann have the effect of increasing yield, of which spray Zhuang Zhuang Feng 750 ml / hm2 yield the best, yield up to 6.2%. Revealed the strong Zhuang Feng, Zhuang Fengan on the regulation of the quality of wheat population and the mechanism of down-to-increase production.
