Effect of Matrix Composition on the Quality of Phoebe zhennan Container Seedlings
In order to investigate the effect of matrix composition on the quality of container Phoebe zhennan seedlings,the growth indexes and stress resistance indexes of container Phoebe zhennan seedlings under different treatments were observed and measured by setting 9 different matrix compositions.The results showed that substrate composition had significant effects on the growth and stress resistance of Phoebe zhennan container seedlings.Under the matrix composition C3,the growth rate of Phoebe zhennan con-tainer seedlings was the fastest,the leaf color was the greenest,and the leaf area was the largest.At the same time,the chlorophyll content of Phoebe zhennan container seedlings under this treatment was the highest,indicating that the plants had the strongest photo-synthetic capacity.The comprehensive analysis showed that matrix composition C3 was the most beneficial to the growth and stress resistance of Phoebe zhennan container seedlings.In order to improve the quality and stress resistance of containerized Phoebe zhen-nan seedlings,it is suggested that C3 should be adopted in the production practice.
