Abstract:

Abstract: It was studied that how the 11 kinds of chemical reagents influenced in the survival rate and growth of 10 varieties of Ping ou hybrid hazel. It shows that the reagents can significantly increase the survival rate of hazel seedlings planting, and promote root and grow part of branches and leaves . Gen te jia treatment makes the highest survival rate, it is up to 86%. WP and NEB treatment make good effect, survival rates are 84% and 82%, which is significantly higher than that of water control treatment (70%). It concluded that WP and the NEB is better than other treatments, since the root, branches and leaves . There is also much difference between the survival rate of Hazel seedling varieties (lines) and the growth of the plant. The survival rate of 86-104 is up to 95%, 84-310 is only 50.83%. In between the chemical treament and tested varieties, there exists interaction of the survival rate of the plants. few treatments of low average survival rate varieties among the treatments are up to 100%. few of treatments in low average survival rate among the varieties are up to 100%.
