不同水肥组合对贵州金花茶生长和活性物质的影响OA

To explore the effects of different water and fertilizer coupling conditions on the growth and physiological and biochemical indicators of Camellia huana in Guizhou,plants with similar growth vigor were selected,and three irrigation volumes and four levels of fertility were set.At the end of the growing season,the biomass,plant height,ground diameter and other growth indicators were measured,and the contents of total flavonoids,total phenols,total sugars,total amino acids,malondialdehyde,proline,catalase and acid phosphatase in leaves were determined.The results showed that among various water and fertilizer coupling patterns,the W2F2 combination[irrigation volume of 800 mL/ind.,fertilizer application(N-P-K)1.6-1.0-1.0 g/ind.]was more conducive to the growth and accumulation of active components of C.huana,and multiple indicators such as aboveground biomass,total biomass,total phenols and total flavonoids reached their peaks.Therefore,it was recommended that when promoting the cultivation of C.huana,the water and fertilizer management measures of the W2F2 combination be adopted,which can promote the growth and secondary metabolite synthesis of C.huana,and significantly improve the stress adaptability and quality of the plants.
