摘　　要：以避雨栽培“红阳”猕猴桃为试材,根据补光位置的差异开展试验,分析不同位置补光对猕猴桃果实营养生长、产量和品质的影响。连续两年的试验结果表明,顶部+底部(D+d)、顶部(D)和底部(d)补光均有促进猕猴桃果实纵、横径生长的作用,且D+d处理在快速膨大期的促进作用尤为明显;补光位置对果形指数的影响差异不显著。连续两年D+d处理的果实产量分别为对照的2.3和2.6倍,且D+d处理的果实维生素C和可溶性固形物含量均显著高于对照处理。相关性分析结果显示,产量和品质的多个指标间呈显著正相关,补光能促进猕猴桃产量和品质的同步提升。综上,D+d补光处理对保障猕猴桃产量、改善果实品质效果最好。本研究为避雨栽培补光体系的构建、补光技术在猕猴桃生产上的应用提供了理论依据。Use Hongyang kiwifruit cultivated under rain shelter as the experimental material,the impacts of different light supplement positions on vegetative growth,yield and quality of kiwifruit were analyzed.The results of two consecutive years of experiments showed that the treatments of top and bottom lighting(D+d),top(D),and bottom(d)lighting promoted the elongation of the longitudinal and transverse diameters of fruit,and the promotion effect of D+d treatment was particularly significant at rapid expansion period.However,there was no significant difference in the impact of lighting positions on the fruit shape index indicator.The fruit yield of D+d treatment for two consecutive years was 2.3 and 2.6 times of that of the control,respectively.The contents of vitamin C and soluble solids under D+d treatment were significantly higher than those of the control.The correlation analysis showed a significant positive correlation between multiple indicators of yield and quality.Supplementing light could improve the yield and quality of kiwifruit together.In summary,D+d supplement of light had the best effect on ensuring kiwifruit yield and improving quality.This study provides a theoretical basis for construction of a light supplement system under rain shelter cultivation and application of supplement light technology in kiwifruit production.
