Effects of Different Foliar Fertilizers on Growth,Development and Fruit Quality of'Pinot Noir'Grape
摘要
Abstract
To explore the effects of different foliar fertilizers on the growth,development and fruit quality of'Pinot Noir'grapes,5-year-old'Pinot Noir'grapevines were used as the experimental materials.6 types of foliar fertilizers,including inorganic nutrition type(T1),amino acid type(T2),hormone type(T3),water-soluble macronutrient type(T4),humic acid type(T5)and resistance induction type(T6)were sprayed,and clean water was sprayed as a control(CK).The changes of leaf area,new shoot base thickness,leaf SPAD value and mineral element content at different stages were analyzed,and the relevant indicators of fruit quality were determined at maturity stage.The results showed that the T5 treatment significantly increased the leaf area of grapes.At 15,30,45,60 and 75 d after flowering,the leaf areas were increased by 14.10%,12.34%,15.47%,15.27%and 15.70%,respectively,compared with that of CK.All treatments increased the new shoot base thickness of grape plants,with the T5 treatment showing the most significant effect.Compared with CK,each treatment increased the leaf SPAD values at different stages,but there was no significant difference between treatments.The mineral element content analysis showed that T1 treatment significantly increased the contents of macronutrients in leaves,among which K content was most significantly increased.T6 treatment had the best effect on the promotion of medium element content,while T5 treatment had a good effect on the accumulation of trace elements,and the accumulation of Cu was significantly increased at 60 and 75 d after flowering.In terms of fruit quality,T5 treatment significantly increased the anthocyanin,flavonoid,tannin and total phenolic content of grape fruits by 16.88%,38.38%,24.74%and 43.13%,respectively,compared with CK.Finally,principal component analysis of the fruit quality-related indicators at harvest showed that T5 treatment had the highest score.In conclusion,all 6 types of foliar fertilizers promoted the growth and fruit quality of'Pinot Noir'grape,with T5 treatment,a humic acid type foliar fertilizer,showing the best results and significantly enhancing fruit quality.Above results provided theoretical guidance for improving grape quality and yield.关键词
