拉枝角度对库尔勒香梨枝叶生长及果实品质的影响
Effects of Branch Bending Angle on the Branch and Leaf Growth and Fruit Quality of Korla Fragrant Pear
摘要
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.关键词
