摘　　要：为评估灵滟、矮壮丰、爱久收、直播龙和劲丰谷德等5种不同化控产品对小麦抗倒伏性和产量的影响,选用济麦22在鄄城县大埝镇进行了田间试验,对不同处理组的小麦株高、穗长、穗粒数、千粒质量、第二节间抗折力、产量和倒伏率进行测定和比较。试验表明,处理组D表现出最佳的综合效果,不仅显著提高了小麦产量(9489.35 kg/hm^(2)),较对照组提高了2.38%,而且保持了良好的抗倒伏性能(第二节间抗折力为14.22 N,倒伏率为1.5%);处理组E同样表现出较高的产量(9375.82 kg/hm^(2)),较对照组提高了1.20%;处理组A和处理组B尽管在产量提升方面表现较弱,但在防止倒伏方面效果显著,其第二节间抗折力分别为17.51 N和15.97 N。The aim of this study was to evaluate the effects of 5 different chemical control products on lodging resistance and yield of wheat,in order to provide scientific basis for improving wheat planting management and production efficiency.The experiment was carried out in Danyan Town with the selection of wheat variety Jimai 22.The wheat plant height,spike length,grain number per spike,thousand grain mass,second node bending resistance,yield and lodging rate of different treatment groups were measured and compared by field experiment.The results showed that different chemical control products had significant effects on the growth index,lodging resistance and yield of wheat.Among them,treatment group D showed the best comprehensive effect,which not only significantly increased wheat yield by 2.38%compared with control group,but also maintained good lodging resistance.Treatment group E also showed higher yield,which increased by 1.20%compared with control group.Treatment groups A and B,although weak in terms of yield improvement,were effective in preventing lodging.The results showed that the effects of different chemical control products on wheat growth index,lodging resistance and yield were significantly different.
