| 将树干注射技术作为正常果树的一种施肥,地比树干注射加土壤施肥，树干注射施肥和常规的土壤施肥加叶面喷肥3种施肥处理的效果，结果表明，含有树干注射施肥的2个处理单叶面积分别增加了8.63％和6.11 cm2，比叶重增加了2.90和0.40 mg/cm2，叶绿体色素的含量也显著产加，其中总叶绿素增加了47.76％和42.13％，含树干注射施肥的2个处理使叶内营养元素含量较均衡，叶片净光合速率分别提高了36.30％和21.28％，单果重提高了17.8％和6.5％，单株产量增加了31.77％和18.26％，增加了座果率和成花率，并提高了花芽质量。 |

| Abstract: |
| Trunk injection as a normal fertilizing method was studied in this paper.Three fertilizing proactices,single trunk injection fertilizing,trunk injection fertilizing and soil fertilizing,soil fertilizing and foliar spray fertilizing,were evaluated.The results showed that the two trunk injection fertilizing practices could increase individual leaf area by 8.63 cm2 and 6.11 cm2,dry weight per cm2 by 2.90 mg/cm2 and 0.40 mg/cm2;the contents of leaf total chlorophyll by 47.76% and 42.13% respectively.The two practices could also balance leaf nutrient elements,raise the net photosynthetic rate by 36.30% and 21.28%,and increase setting percentage.Individual fruit weight increased by 17.8% and 6.5%.and yield per tree by 31.77% and 18.26%. |
