用主干渗注、喷叶、土施等方法以ＰＰ３３３处理２年生二花槽和红荷包２品种杏树，处理当年能明显降低干断面积、冠径、冠高、枝条长度和节间长度，增加了单位校长上的花芽数量，喷叶和土施与对照相比达到显著性差异水平，处理的第２年，增加了叶片厚度、百叶重量和单叶面积，显著地提高单果重量和单株产量，提早果实成熟５－７天；增加了叶片光合强度和叶绿素含量，降低了蒸腾强度，提高了气孔扩散阻力，但降低了根系活力，３种处理方法以喷叶和土施法含ＰＰ３３３较多，效果亦最明显。
The trunk infiltration, spraying leaves and soil application were used to treat 2-year-old Erhualian and Honghebao 2 apricot trees with PP333, which could significantly reduce the dry area, crown diameter, crown height, branch length and internode length, The number of flower buds per unit head increased, leaf spraying and soil application reached significant differences compared with the control, and in the second year of treatment, the leaf thickness, leaf weight and single leaf area were increased, Yield, premature mature fruit 5-7 days; increased leaf photosynthetic intensity and chlorophyll content, reduced transpiration, increased stomatal diffusion resistance, but reduced root activity, the three treatment methods to spray leaf and soil fertility with PP333 more , The effect is also the most obvious.
