| Abstract: | The growth and fruiting features were invested consistently for five years in young precocious walnut, and then the indexes of tree structure for its highyield were pointed out. The regulating protocol to the indexes was studied by comparing the effect of fertilizer ratio, crop density, and pruning cut length on growth and fruiting. |
