| Abstract: | 【Objective】This study is to screen out the best retardant with the best concentration which might control the nutrition growth and increase the ratio of mixed buds of the walnut by using different concentrations of the three plant growth retardants: B9,CCC and PP333.【Method】Xinfeng walnut was used as the test material,the three plant growth retardants(B9,CCC and PP333) were set up with different concentrations at 500,1 000,1 500,2 000 mg/L and then they were sprayed on the leaves of walnut;the effects of the three plant retardants on the branching quantity,branch length,branch thickness,mixed buds quantity of walnut were analyzed.【Result】After B9 at 1 500 mg/L concentration being sprayed on walnut,the number of mixed buds and branches could be increased by 403%, and 66% respectively,while the branch length was decreased to 59% than that of the control group.It had no effect on branch thickness.【Conclusion】A basic conclusion can be drawn that by using B9 at 1 500 mg/L concentration,accompanied by fertilizer and water management on the low-yield Xinfeng walnut orchards,the walnut's branches can be controlled,thus leading to the increase of the ratio of mixed buds. |
