树形改造对苹果树枝叶分布结构与性能的影响
Effect of tree reconstruction on apple orchard canopy structure and performance
摘要
Abstract
Obj ective]In order to explore the dual effect of tree of technical transformation on the yield and quality of fruit trees in comprehensively improve,[Methods]the study chose Malus pumila Mill as the material,and based on tree structure transformation of old orchard to study the impact of apple orchard canopy structure and performance. [Results]The ratio of external bearing branch including long,middle and short changed from 3∶3∶3 to 2∶3∶5 ,while the ratio of internal bearing branch changed from 1∶3∶6 to 2∶3∶5,the leaf-fruit ratio raised by 20∶1 to 35∶1,the rela-tive light of internal canopy raised by 55.3% to 68.4%,the area of single leaf increased from 26.6 cm2 to 33.6 cm2 , significantly increased by 26.3%,compared to the CK,the difference of leaf chlorophyll content rate was extremely significant,respectively raised by 59.9 mg·m-2 to 93.3 mg·m-2 .But compared to the CK,the difference of the exter-nal relative light,single leaf area,and leaf chlorophyll content change were not significant.Photosynthetic rate change were not significant.[Conclusion]The study supplied effectively the theoretical basis and technical guidance of training and pruning to northern China adult apple orchard.关键词
