摘要:
为探索不同外源植物生长调节剂对大豆玉米带状复合种植模式下玉米和大豆茎秆抗倒伏性状及产量的影响,以江玉877和齐黄34为试验材料,采用玉米大豆“2+4”间作模式,设置3个调节剂处理,分别为喷施乙烯利700 mg/L(A)、喷施多效唑100 mg/L(B)、喷施乙烯利700 mg/L+多效唑100 mg/L(C),以喷施清水为对照(CK),研究在大豆玉米带状复合种植条件下外源植物生长调节剂对玉米和大豆茎秆形态、抗折力和产量等的影响。结果表明,乙烯利处理能显著降低玉米株高和穗位高、增加节间茎粗、提高基部节间抗折力,但对大豆茎秆的抗倒伏形态无显著影响；多效唑则相反,仅对大豆植株茎秆抗倒伏形态增强效果显著,对玉米植株抗倒伏形态无显著影响。乙烯利和多效唑复配处理兼具二者优点,与对照相比,乙烯利和多效唑复配处理能显著降低玉米和大豆株高,显著增加大豆和玉米抗折力和茎秆密度,显著提升玉米和大豆产量。综上,在大豆玉米复合种植模式下,乙烯利和多效唑复配剂对玉米和大豆抗倒伏能力的提升和产量的增加效果优于2种单剂,有利于提高作物抗倒伏能力,优化产量构成并增产。
Abstract:
To explore the effects of different exogenous plant growth regulators on stem lodging resistance and yield in a maize-soybean strip intercropping system, a study was conducted using Jiangyu 877 (maize) and Qihuang 34 (soybean) under a “2+4” intercropping pattern. Three plant growth regulator treatments were set, namely ethephon at 700 mg/L (A), paclobutrazol at 100 mg/L (B), and a combination of ethephon at 700 mg/L + paclobutrazol at 100 mg/L (C), with water spraying as the control (CK), to study their effects on stem morphology, breaking resistance, and yield. The results showed that ethephon treatment significantly reduced maize plant height and ear height, increased internode stem diameter, and improved basal internode breaking resistance, but had no significant effect on the lodging resistance morphology of soybean stems. In contrast, paclobutrazol significantly enhanced soybean stem lodging-resistant morphology, but did not significantly impact maize lodging and related traits. The combined ethephon and paclobutrazol treatment integrated the advantages of both regulators. Compared to the control, the combined treatment significantly reduced plant height in maize and soybean, increased the breaking resistance and stem density of both crops, and improved their yields. In conclusion, in a maize-soybean intercropping system, the combined ethephon and paclobutrazol treatment is more effective than single-regulator treatments in enhancing lodging resistance and increasing yields for both crops, which enhances crop lodging resistance, optimizes yield components, and ultimately leads to higher yields of both crops.
