有机肥和生物炭施用对猕猴桃果实品质的影响

以4年嫁接树龄的“贵长”猕猴桃为试验材料,采用田间试验的方法,共设置4个试验处理,测定了不同施肥处理下猕猴桃的产量和品质指标,研究了生物炭和有机肥混施以及单施处理下对猕猴桃产量以及品质指标的影响,以期为“贵长”猕猴桃果实品质和产量的提升提供参考依据。结果表明:与对照相比,各施肥处理极显著提高了果实的产量及单果质量、可溶性固形物、可溶性糖、可溶性蛋白质、糖酸比和维生素C含量,显著降低了可滴定酸含量;通过主成分分析得到各处理下的果实品质综合得分,表现为2种肥的混合配施效果优于单施,而单施优于对照。生物炭和有机肥的施入可以提升猕猴桃的果实品质和产量,其中生物炭肥和有机肥混合施肥的处理施肥效果最佳。

Effects of Organic Fertilizer and Biochar Application on Fruit Quality of Kiwifruit

The four-year-old‘Guichang’kiwifruit was used as the test material,and four test treatments were set up for field trials.The yield and quality indexes of kiwifruit under different fertilization treatments were measured,the effects of the mixed application of biochar and organic fertilizer and single application on the yield and quality of kiwifruit were studied,in order to provide a reference for the improvement of the quality and yield of‘Guichang’kiwifruit.The results showed that compared with the control,each fertilization treatment significantly increased the yield and quality of single fruit,soluble solids,soluble sugar,soluble protein,sugar-acid ratio,and vitamin C content,and significantly reduced the titratable acid content.The comprehensive score of fruit quality under each treatment was obtained by principal component analysis,which showed that the effect of mixed application of the two fertilizers were better than single application,and single application was better than the control.It showed that the application of biochar and organic fertilizer could improve the fruit quality and yield of kiwifruit,and the mixed fertilization of biochar and organic fertilizer had the best fertilization effect.
