喷施不同植物生长调节剂对盐碱地小麦生长发育的影响
Effects of Different Plant Growth Regulators on Wheat Growth and Development in the Saline-alkali Land
摘要
Abstract
INTRODUCTION:Plant growth regulators are natural or artificially synthesized chemical substances that play an impor-tant 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.关键词
