不同施肥处理对青钱柳生长及叶片品质的影响
The Effect of Applying Different Types of Fertilizers on the Growth and Leaf Quality of Cyclocarya paliurus
摘要
Abstract
Taking 2-year-old Cyclocarya paliurus seedling as the test material,and the experiment was con-ducted in the field conditions,6 different fertilizers were set up,and the growth indicators,photosynthesis indicat-ors,mineral elements and secondary metabolites content of different treatments were measured at 2 leaf harvest-ing months in April and June,respectively.The differences between different fertilization treatments were com-pared by one-way ANOVA,and the best fertilization method was comprehensively evaluated by principal com-ponent analysis.The results show that compared with the CK,the application of different fertilizers promoted the growth of C.paliurus trees,and all indicators were the highest in T5 treatment;the net photosynthetic rate,tran-spiration rate and stomatal conductance of all treatment groups increased over time and were all significantly higher than those of CK,and the intercellular CO2 concentration of CK was the highest at 275.00 μmol/(m2·s);the calcium,potassium and phosphorus element contents of the leaves in T1 treatment were the highest,and the mag-nesium content of T4 treatment was the highest.Compared with April,the mass elements content in leaves except magnesium increased in June,and the contents of copper,zinc,nickel,and iron elements increased with the pro-gression of treatment time,with the highest zinc,nickel,and iron contents in T5.The water-soluble polysacchar-ides and total triterpenes content of T5 leaves were the highest,while the total flavonoids content of T4 leaves was the highest.The correlation analysis of various indicators showed that,except for magnesium and manganese ele-ments,the growth indicators of tree bodies,the photosynthesis indicators of leaves,and the contents of mineral elements and secondary metabolites were all significantly positively correlated.Principal component analysis evaluated that T5 had the best overall characteristics and ranked first.In conclusion,if the harvest time is set in April and June in the poor soil areas of Hunan Province,T5(compound fertilizer+water-soluble fertilizer contain-ing amino acids)fertilization treatment is more conducive to the growth and development of C.paliurus and the accumulation of mineral elements and secondary metabolites in leaves.关键词
