目的:探讨叶面喷施不同浓度锌肥对万寿菊生长、生理、产量及品质的影响,为其锌肥施用提供依据。方法:采用单因素随机区组设计,以清水为对照,共设6个处理,测定万寿菊生长、生理、产量和品质指标。结果:锌肥浓度为800倍液时,株高、茎粗、...目的:探讨叶面喷施不同浓度锌肥对万寿菊生长、生理、产量及品质的影响,为其锌肥施用提供依据。方法:采用单因素随机区组设计,以清水为对照,共设6个处理,测定万寿菊生长、生理、产量和品质指标。结果:锌肥浓度为800倍液时,株高、茎粗、花径、产量、收益和CAT活性分别比对照提高6.72%、7.40%、7.27%、52.84%、57.37%和152.79%,三次采收万寿菊花的多酚、黄酮和叶黄素平均比对照增加28.87%、27.53%和33.13%。结论:叶面喷施锌肥对万寿菊生长、生理、产量和品质有显著影响。Objective: The effects of zinc fertilizer with different concentrations on the growth, physiology, yield and quality of marigold were studied to provide scientific basis for its fertilization and cultivation. Methods: A single factor random block design was used to determine the growth, physiology, yield and quality of marigold in 6 treatments with clean water as the control. Results: When the concentration of zinc fertilizer was 800 times liquid, all the indexes were better than other treatments. Among them, plant height, stem diameter, flower diameter, yield, yield and CAT activity were increased by 6.72%, 7.40%, 7.27%, 52.84%, 57.37% and 152.79%, respectively. The polyphenols, flavonoids and lutein in marigold harvested three times were increased by 28.87%, 27.53% and 33.13% compared with control. Conclusion: Spraying zinc fertilizer on the leaf surface of Marigold has significant effects on growth, physiology, yield and quality.展开更多
