摘要: 以玉米品种郑单958、先玉335、豫单132、浚单20、联创808、鼎优163等为试验材料,研究了2种乙烯利复配剂对不同生态地区不同玉米品种抗倒能力及产量的影响。结果表明:施用2种化控剂后玉米的抗倒伏性能显著提高,施用苄氨基嘌呤(6-BA)·乙烯利(ETH)后,浚单20的倒伏率降低6.1百分点;施用胺鲜酯(DTA-6)·ETH后,郑单958的倒伏率降低了6.2百分点。在商丘地区施用DTA-6·ETH处理联创808后,其穗位系数降低9.8百分点,在驻马店地区施用6-BA·ETH处理鼎优163后,其穗位系数降低11.3 百分点。同时,2种乙烯利复配剂均能增强玉米的茎秆穿刺强度。同一玉米品种进行不同化控处理后的表型性状如穗长、穗粗、穗行数等差异不显著,但行粒数、千粒重和产量等性状在各处理和年份间存在显著性差异。此外,各地区玉米品种化控处理后的产量表现各异,鹤壁、周口、驻马店地区施用化控剂DTA-6·ETH的产量表现优于化控剂6-BA·ETH,三地使用DTA-6·ETH处理后较清水CK平均增产4.22%、8.41%、5.67%,而在商丘、南阳、长葛地区施用化控剂6-BA·ETH的产量表现优于化控剂DTA-6·ETH,6-BA·ETH处理较清水CK平均增产6.96%、7.54%、5.56%。

Abstract:

Taking Zhengdan 958, Xianyu 335, Yudan 132, Xundan 20, Lianchuang 808 and Dingyou 163 as materials, the effects of two ethephon compound agents on lodging resistance and yield of different maize varieties in different ecological regions were studied. The results showed that the lodging resistance is obviously improved after the application of the two chemicals. The lodging risk of Xundan 20 was reduced by 6.1 percentage points after applying 6-BA·ETH chemical control agent, and that of Zhengdan 958 was reduced by 6.2 percentage points after applying DTA-6·ETH chemical control agent. The ear position coefficient of Lianchuang 808 decreased by 9.8 percentage points after applying DTA-6·ETH in Shangqiu, and that of Dingyou 163 decreased by 11.3 percentage points after applying 6-BA·ETH in Zhumadian. At the same time, the puncture strength of the stem was enhanced. After different chemical control treatments, the phenotypic traits such as ear length, ear diameter and rows were not significantly different in the same variety, but the grain number per row, thousand kernel weight and yield were significantly different among treatments and years. In addition, the yield performance of maize varieties after chemical control treatment varied in different regions. The effect of applying chemical control agent DTA-6·ETH in Hebi, Zhoukou and Zhumadian was better than that of chemical control agent 6-BA·ETH, with an average increase of 4.22%, 8.41% and 5.67% compared with CK, and the effect of applying chemical control agent 6-BA·ETH in Shangqiu, Nanyang and Changge is better than that of chemical control agent DTA-6·ETH, with an average increase of 6.96%, 7.54% and 5.56% compared with CK.
