麦巨金微乳剂对小麦抗倒伏性及产量形成的效应

为给化学调控剂麦巨金微乳剂的推广应用提供依据,以小麦品种郑州9023为试验材料,采用喷施和拌种两种处理方法,研究其对小麦形态、茎秆结构、光合作用及产量构成要素等指标的影响.结果表明,施用麦巨金微乳剂显著提高了小麦茎秆抗倒能力.施用麦巨金微乳剂后小麦基部节间长度降低,而基部节间单位长度重量增加.抽穗后化控处理的小麦旗叶净光合速率、光合有效辐射均比对照高,并且在灌浆时差异显著.喷施处理的产量与对照相比无显著差异,拌种处理的小麦产量明显高于对照.其中,以5 mL/10 kg拌种处理的效果最好,产量比对照高16.6%.

Effect of Maijujin Microemulsion on Lodging resistance and Yield Forming of Wheat

Field experiments were conducted using wheat Zhengzhou 9023 as the experiment material and applying the chemical control agent Maijujin Microemulsion.Through spraying and seed-dressing treatments, the experiment investigated the effect of Maijujin micvoemulsion on the form, stem structure, photosynthesis and yield of wheat. The results showed that the chemical control agent significantly improved the resistance of wheat stem to lodging. Compared with the control, all the basal internode lengths decreased. Photosynthetic rate and photosythetic active radiation were higher, with significant difference at grain-filling stage. Compared with the control ,the yield of seed-dressing treatments was significant higher, the yield of spraying was higher but no significant difference. The yield of B5 (5 mL/10 kg seed) treatment increased than the control by 16.6%.
