摘　　要：为了提高谷子抗倒伏能力,研究矮化处理对谷子倒伏性状及产量的影响。结果表明:在拔节早期喷施矮壮剂能显著降低株高、鲜重,缩短节间长度,提高茎秆抗折力、根重及茎粗等指标,从而增加倒伏指数和倒伏系数,并且产量没有明显降低。矮化处理能显著提高谷子的抗倒伏能力。In order to improve the ability of lodging resistance of millet, the effect of dwarf treatment on yield and lodging resistance of millet was studied. The results showed that at the early jointing stage of millet, spra ying stocky agent could significantly reduce the height, fresh weight, and improve anti-fracture, root weight, stem diameter, thereby increase the lodging index and lodging coefficient, and no significant reduction in yield. Dwarfing treatment could significantly improve the ability of lodging resistance of millet.
