摘要:
 探讨省力密植栽培模式下库尔勒香梨枝条适宜的拉技角度，研究不同拉技角度（60°~75°、75°~90°、90°~105°、105°~120°）对香梨叶片营养物质含量、枝类特性和果实品质的影响。结果表明，不同拉枝角度处理均使叶片单叶鲜重、单叶干重、单叶面积和单叶厚度增加，60°~105°的拉枝处理使叶片叶绿素总量显著增加，拉枝75°~90°时，叶片氮素营养和钾素营养含量最高。不同拉枝角度处理均使香梨树的长果枝比例减小，中、短果枝比例增加，拉枝角度为75°~90°时，枝条抽生中、短果枝的比例高于其他处理。拉枝角度为75°~90°时，果实硬度、可溶性糖、可滴定酸、糖酸比、蛋白质、维生素C和石细胞含量等指标要优于其他处理，且果实单果质量最大。综合分析认为，库尔勒香梨省力密植栽培模式下树体适宜的拉枝角度为75°~90°。
Abstract:
 In order to select the suitable angles of branch bending for labor-saving and high-density cultivation of Korla fragrant pear tree,different bending angles were set up: 60°-75°,75°-90°,90°-105°,105°-120° to study its effects on the leaf nutrients,branch characters and fruit quality.The results showed that the branch bending could improve single leaf fresh weight,dry weight,area,and thickness.The chlorophyll content significantly increased when the branch angles were 60°-105°.Leaf potassium and nitrogen contents were the highest when the branch angles were 75°-90°.The ratio of long branches decreased and the ratios of middle and short branch increased after bending.The ratios of middle and short branches were higher than those of other angles when the bending angles were 75°-90°.When the angles were 75°-90°,the fruit firmness,soluble sugars content,titratable acidity content,protein content,sugar-acid ratio,vitamin C content and stone cell content were superior to other treatments,and the single fruit weight was the highest.Comprehensively considering the above indexes,the preferable branch bending angles for the pear were 75°-90° under dense system.
