摘要: 以巨峰葡萄为试验材料,采用硒肥树干注射的方式,研究了不同量的硒对巨峰葡萄硒含量和品质的影响。结果表明,树干注射不同浓度的硒肥显著提高了葡萄鲜果、叶片和茎中的硒含量,分别可达到0.035、1.466、1.476 mg/kg。树干注射硒肥明显增加了葡萄果实单果重、可溶性固形物、可溶性糖、酒石酸、维生素C、丙二酸和柠檬酸含量,降低了可滴定酸、草酸和琥珀酸含量,与硒肥用量相关性最显著的为草酸(-0.861)和丙二酸(0.832)。结果表明,树干注射硒肥能显著增加葡萄果实硒含量、提高果实品质、影响果实的有机酸含量,尤其是降低了草酸含量和增加了丙二酸含量,综合分析以50 mg/L处理效果最好。

Abstract: In order to study the effects of different amounts of selenium on selenium content and quality of Kyoho grape,selenium fertilizer was applied with trunk injection.The results showed that the selenium content of fresh fruits,leaves and main stems was significantly increased by injecting different concentrations of selenium fertilizer into the trunk,reaching 0.035,1.466 and 1.476 mg/kg,respectively.The single fruit weight and the content of soluble solid,soluble sugar,titratable acid,VC,citric acid and malonic acid increased,and the content of titratable acid,oxalic acid and succinic acid decreased by applying selenium fertilizer with trunk injection.The most significant correlation with the amount of selenium fertilizer was oxalic acid(-0.861) and malonic acid(0.832).It illustrated that the selenium content and the quality of grape fruits were significantly improved,and the content of organic acids in the fruits were affected,especially the content of oxalic acid and malonic acid by trunk injection of selenium fertilizer.According to comprehensive analysis,the trunk injection of 50 mg/L was the best treatment.
