Abstract

Abstract:

【Objective】 By studying the effects of different growth regulators on stem characteristics and lodging resistance of winter wheat under drip irrigation, the most suitable exogenous growth regulators for winter wheat under drip irrigation were selected to provide theoretical basis for lodging resistance and control measures of Xinjiang drip irrigation wheat.【Methods】 Using Xindong 18 as the material, six treatments including clear water control (CK), calcium recyclate·enlobuzole (A), Aizhuangin (B), maggikin (C), antipour ester (D) and prelobuzole (E) were set up under field drip irrigation from 2021 to 2022 with different anti-lodging regulators as test factors.The effects of different treatments on plant height, center of gravity height, internode length, stem diameter, stem bending resistance and yield of winter wheat under drip irrigation were analyzed.【Results】 The results showed that the plant height, center of gravity height and basal internode length of wheat were decreased and the stem thickness of basal internode was increased in all treatments except C.Compared with CK (water control), five treatments, A, B, C, D and E, increased the bending resistance of the second internode of wheat base by 9.44%, 19.65%, 5.20%, 16.57% and 20.00%, respectively.In terms of yield, the number of grains per ear increased by 0.97%-3.53% in the treatment of spraying regulator.The increase of 1000-particle weight was not obvious, and the 1,000-particle weight under Aizhuangsu treatment was increased by 3.93% compared with CK treatment.In terms of yield, the wheat treated with the five regulators could increase the yield by 1.10%-14.39%, and the yield increase effect was B>C>A>D>E【Conclusion】 It was concluded that all the five exogenous growth regulators had different effects on lodging resistance traits in wheat.In addition to the improvement of plant caving resistance, in terms of yield, the effective panicle number and kernel number per panicle were increased more significantly by calcium alicyclate, enlobuzole and maggetin, and the effect of Aizonin on 1,000-grain weight was better.Compared with CK, different regulator treatments increased the yield by 1.10%-14.39%.The overall effect was better, followed by calcium tetracycline and enlobuzole.

摘要：

【目的】研究不同外源生长调节剂对滴灌冬小麦茎秆特征及其抗倒伏性状的影响,筛选滴灌冬小麦最适外源生长调节剂,为新疆滴灌小麦抗倒伏及其调控措施提供理论依据。【方法】以新冬18号为材料,于2021~2022年在大田滴灌条件下,以不同的抗倒伏调节剂为试验因子,设置清水对照(CK)、调环酸钙·烯效唑(A)、矮壮素(B)、麦巨金(C)、抗倒酯(D)、多效唑(E)共6个处理,分析不同处理对滴灌冬小麦株高、重心高度、节间长度、茎粗、茎秆抗折力以及产量的影响。【结果】除C处理外,其余处理滴灌冬小麦的株高、重心高度、基部节间长度均表现为不同程度的下降,基部茎秆抗折力均表现为不同程度上升,各处理滴灌冬小麦基部茎秆抗折力分别较CK提高了10.14%、16.11%、7.70%、14.22%和18.08%。与CK相比,A、C处理能明显提高滴灌冬小麦的有效穗数和穗粒数,不同调节剂处理下冬小麦籽粒产量表现为B>C>A>D>E,与CK相比,喷施调节剂处理下的滴灌冬小麦可增产1.10%~14.39%,其中A、B、C处理增产幅度均在10%以上。【结论】调环酸钙·烯效唑(A)和矮壮素(B)处理下,滴灌冬小麦株高相对适宜、茎秆抗倒伏性较好、籽粒增产幅度大。
