摘　　要：作者从十多年的果树修剪实践经验中探索、总结出一套更深层次的剪枝理论——"增阻降流法"苹果早果、丰产、稳产修剪理论。该理论依据物理学的电路原理创新性地提出并定性论证了"根颈以上任何枝,疏则增阻(树阻),截则降阻(树阻)""疏除基部同枝轴低阻大型枝比高阻小型枝树阻增幅大""增阻降流修剪法可使苹果树实现早果、丰产、稳产"三大论点,并在试验园中得到成功应用,为我国果树修剪理论的深化增加了革命性的新篇章。Based on the experiences of fruit tree pruning over 10 years,the author summarized and explored a set of theory of pruning at a deeper level which used the method of increasing resistance and decreasing current of apple trees to achieve early fruiting,high and stable yield.In the theory the following three main arguments were addressed innovatively and proved qualitatively with the circuit principle in physics：1.Thinning any branch above rhizome would increase the resistance of tree,on the contrary,short cutting would decrease it;2.Thinning a large branch in basal part with low resistance would have a larger increase amplitude of tree resistance than a small branch with high resistance in the same shoot;3.The pruning method of increasing resistance and decreasing current of apple trees could make it early fruiting,high and stable yield.The theory was successfully applied in the experimental orchard,and it would write a new chapter in deepening the fruit tree pruning theory of our country.
