摘　　要：通过连续5年对早实核桃幼树生长、结果形态指标的调查研究,分析提出了早实核桃幼树丰产的树相指标。通过比较不同肥料配比、不同留果量及枝条短截程度对生长、结果的影响,探讨了早实核桃幼树期树相指标调控的方法。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.
