| 摘 要： | 以瑞蟠5号桃树为试材,研究了倾斜主干偏展形和“Y”字形两种树形的光分布与果实产量、品质的关系。结果表明:倾斜主干偏展形比“Y”字形树体的相对光照分布均匀,有效光照体积比率高,果实产量、品质随相对光照增强而提高。建立了品质因素与相对光照强度的回归方程,对方程求极值获得了果实品质因素最大的相对光照强度为:单果重量27.22%,可溶性固形物71.66%,果实着色83.45%;综合分析,相对光照强度在34%时,为瑞蟠5号桃优质生产的最低界限。

| Abstract: | Trees trained in Slanting Central Leader shape and“Y”system were used for observing the effects of light distri-bution on the yield and fruit quality.Results showed that light distribution,ratio of effective relative light intensity,produc-tion and fruit quality of the trees trained in Slanting Central Leader shape were better than those trained in the“Y”system.The mathematical method was used to set up regression equation about the relationship between the light intensity and yield and fruit quality.Analysis showed that34%of full sunlight was the minimum value for receiving good fruit quality and high yield of Ruipan5flat peach variety. |
