Abstract

Abstract:

【Objective】 To select the most suitable growth regulators and the application times of regulators in the hope of providing theoretical basis for lodging resistance and control measures of Xinjiang drip irrigation wheat. 【Methods】 Xinjong 18 were taken as the material, and different regulators as the main zones under the field drip irrigation conditions from 2021 to 2022: clear water control (CK), calcium modulate · Enodozole (A), nanocin (B), enodozole·methylpiperonium (C), antyloxyl ester (D), polylodozole (E), and in addition, the frequency of regulator application was used as the secondary zones: A total of 12 treatments were applied at rise stage (P₁) and rise stage + jointing stage (P₂) to analyze 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. 【Results】 The results showed that the plant height could be controlled effectively, the center of gravity height and internode length could be reduced, and the bending resistance of the basal stems could be improved. The bending resistance of the basal stems was increased by 8.97% and 14.89% in the treatment of one-time and twice spraying of regulator. BP₂ treatment could effectively increase the effective panicle number and 1000-grain weight, and the panicle number increased significantly under CP₂ treatment. Under the premise of spraying one regulator, the yield increased by more than 10% under AP₁, BP₁ and CP₁ treatments, and under the premise of spraying two regulators, the yield increased by more than 10% under AP₂, BP₂, CP₂ and DP₂ treatments. 【Conclusion】 The plant height of AP₂ and BP₂ are relatively suitable, the stem lodging resistance is better, and the grain yield is increased greatly.

摘要：

【目的】 研究不同外源生长调节剂及其喷施次数对滴灌冬小麦茎秆特征及其抗倒伏性的影响,筛选滴灌冬小麦最适的外源生长调节剂及调节剂喷施次数,为新疆滴灌冬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,采用裂区试验设计,以清水对照(CK)、调环酸钙·烯效唑(A)、矮壮素(B)、烯效·甲哌鎓(C)、抗倒酯(D)、多效唑(E)为主区,起身期喷施(P₁)、起身期+拔节期各喷施1次(P₂)为副区,共计12个处理。研究不同处理对滴灌冬小麦株高、重心高度、节间长度、茎秆抗折力以及产量的影响。【结果】 施用调节剂各处理均能有效抑制滴灌冬小麦株高,降低重心高度和节间长度,提高基部茎秆抗折力,喷施1次调节剂和喷施2次调节剂的处理基部茎秆抗折力平均提高了8.97%和14.89%。BP₂处理可有效提高滴灌冬小麦有效穗数和千粒重,CP₂处理下滴灌冬小麦穗数增加明显,喷施1次调节剂前提下,AP₁、BP₁、CP₁处理增产达到10%以上,喷施2次调节剂前提下,AP₂、BP₂、CP₂、DP₂处理增产均能达到10%以上。【结论】 在起身期和拔节期分别喷施1次调环酸钙·烯效唑(AP₂)和矮壮素(BP₂)株高相对适宜、茎秆抗倒伏性较好、籽粒增产幅度大。
