摘要: 植物生长调节剂是天然或人工合成的化学物质, 它们不仅对作物的生长发育具有重要调节作用, 还能提高植物的抗逆性。为研究不同植物生长调节剂对盐碱胁迫下小麦(Triticum aestivum)生长发育的影响, 探索提高盐碱地作物产量的方法, 在2023-2024年间, 于黄河三角洲农业高新技术产业示范区的盐碱地开展小麦喷施试验。试验分为4组, 包括蒸馏水对照组、0.5%褐藻寡糖组、植物黄金组以及0.5%褐藻寡糖与植物黄金的混合喷施组, 分别于2024年3月28日、4月12日、4月28日和5月12日对小麦进行喷施。结果表明, 喷施褐藻寡糖与植物黄金的混合物后, 小麦的穗粒数和百粒重显著增加。特别是混合喷施组, 其盐碱地小麦的产量达每公顷1 174.5 kg, 较单独喷施褐藻寡糖组和植物黄金组分别提高了14.4%和46.9%。综上表明, 褐藻寡糖与植物黄金联合应用能显著提高小麦在盐碱地的适应性, 显示出其在盐碱地小麦生产中的重要应用潜力。

Abstract: INTRODUCTION:Plant growth regulators are natural or artificially synthesized chemical substances that play an important regulatory role in the growth and development of crops, and can enhance the resistance of plants to stress. RATIONALE To study the effects of different plant growth regulators on the growth and development of wheat under salt-alkali stress, and to explore methods to increase crop yield in saline-alkali land, we conducted spraying experiments on wheat in saline-alkali soil in the Yellow River Delta Agricultural High-tech Industry Demonstration Zone from 2023 to 2024. The experiment was divided into four groups: a distilled water control group, a 0.5% alginate aligosaccharide group, a Plant Gold group, and a mixed group of 0.5% alginate aligosaccharide and Plant Gold. The wheat was sprayed on March 28, April 12, April 28, and May 12, 2024. RESULTS: The results showed that after spraying alginate oligosaccharide and its mixture with Plant Gold, the number of grains per ear and the 100-grain weight of wheat significantly increased. In particular, the group that received the mixture of alginate oligosaccharide and Plant Gold achieved a theoretical yield of 1 174.5 kg·hm-2 for wheat in saline-alkali soil, which was an increase of 14.4% and 46.9% compared to the groups treated with only alginate oligosaccharide and Plant Gold, respectively. CONCLUSION: Therefore, the combined application of alginate oligosaccharide and Plant Gold can significantly enhance the adaptability of wheat in saline-alkali land, demonstrating its important application potential in wheat production in such environments. After selecting 1 m × 1 m sample plots within the experimental block and conducting spray tests with different plant growth regulators, the theoretical yields of different groups showed different changes. Among them, the yield of the mixed spray group was significantly higher than that of the control group.
