氮磷肥对金银花生长发育及其有效成分含量的影响
Effects of Nitrogen and Phosphorus Fertilizers on Growth and Development of Lonicera japonica and Content of Its Effective Components
摘要
Abstract
This paper used pot culture method to study the effects of different nitrogen and phosphorus fertilizers application on the leaf area,100-leaf weight,1000-bud weight,photosynthetic pigment content,and effective component content of Lonicera japonica.The results showed that,based on the basic properties of the tested soil,the application of nitrogen fertilizer could significantly increase the content of photosynthetic pigments in Lonicera japonica leaves.When the nitrogen fertilizer application rate was 0-15 g/plant,the growth indicators of Lonicera japonica increased with the increase of nitrogen fertilizer application rate.Among them,the best growth indicators of Lonicera japonica were achieved when the nitrogen fertilizer application rate was 15 g/plant.When the nitrogen fertilizer application rate was 45 g/plant,the contents of chlorogenic acid and total flavonoids in Lonicera japonica reached the highest,both significantly higher than those in other treatments.The effects of different phosphorus fertilizer treatments on the growth of Lonicera japonica were not significant,but excessive application of phosphorus fertilizer was detrimental to the growth of Lonicera japonica.When phosphorus fertilizer application rate was 30 g/plant,the contents of chlorogenic acid and total flavonoids in Lonicera japonica reached their maximum values.When phosphorus fertilizer application rate exceeded 30 g/plant,the contents of chlorogenic acid and total flavonoids in Lonicera japonica significantly decreased.The best application rates for the growth,development,and quality of Lonicera japonica were 15-45 g/plant of nitrogen fertilizer and 10-30 g/plant of phosphorus fertilizer.关键词
