不同树形对黄冠梨果实品质和产量及生产成本的影响
Effects of Different Tree Shapes on the Quality,Yield and Production Cost of Huangguan Pear Fruits
摘要
Abstract
To investigate the effects of different tree shapes on the fruit quality,yield,and economic benefits of Pyrus pyrifolia'Huangguan'so as to provide theoretical support for the scientific cultivation and management of pear trees and industrial upgrading,this study selected 3 typical tree shapes,namely double-arm parallel trellis system,high-density cylindrical,and spindle systems,as the research objects.Fruit traits and physiological and biochemical indices of Huangguan pear under different systems were deter-mined,and the costs of orchard establishment and cultivation management were statistically analyzed.Results showed that under the double-arm paralleltrellis system of Huangguan pears,the single fruit weight(341.51 g),fruit longitudinal diameter(82.36 mm),fruit transverse diameter(84.66 mm),soluble solids(122.6 g/kg),sucrose content(19.09 mg/g FW),and chlorophyll SPAD value(52.70)were all significantly better than those of other systems.In addition,this system achieved the highest net income,at 61 778 Yuan/ha,and the highest rate of return,at 61.53%,while showing the lowest cultivation and management cost,at 38 625 Yuan/ha,however,its orchard establishment cost was the highest.In summary,the double-arm paralleltrellis system can significantly improve the fruit quali-ty of Huangguan pears,whereasthe high-density cylindrical systme produces the highest yield,thereby increasing economic benefits.Nevertheless,the high orchard establishment cost should be carefully weighed,and its promotion and application are recommended in accordance with farmers'financial and technical conditions.关键词
