Effects of Formulated Fertilization on Fruit Quality of'Shine Muscat'Grape under Rain-Shelter Cultivation in the Main Growing Season
摘要
Abstract
To develop an optimal theoretical fertilization strategy based on fruit quality indices,this study examined the relationship between different fertilizer ratios and the quality of'Shine Muscat'grape.Using'Shine Muscat'grown under rain-shelter cultivation in the main growing season,a"5416"formulated fertilization experiment was conducted.A series of fruit quality parameters were measured and a comprehensive quality index was calculated to explore the correlations between mineral element application rates and fruit quality.An incomplete orthogonal variance analysis method was employed to predict the optimal fertilization scheme for quality indicators and to propose subsequent optimization strategies.The results showed that nitrogen(N)application rate was highly correlated with berry weight and titratable acidity.Phosphorus(P)application rate exhibited strong correlations with ascorbic acid content,soluble solids content,and the quality index.Potassium(K)application rate was closely associated with the color index and ascorbic acid content.Calcium(Ca)application rate had the strongest correlation with the L* value and the quality index,while magnesium(Mg)application rate was highly correlated with the C* value and skin puncture firmness.Among these,the application rates of P,Mg,and N were identified as the most critical factors determining the fruit quality of'Shine Muscat'grape cultivated in rain-shelter facilities in Xichang during the main season.Soil calcium supply at the experimental site was adequate,so no additional calcium fertilizer is currently needed.The recommended application rates for N,P,K,Ca,and Mg are 133.58 kg·hm-2(expressed as N),123.43 kg·hm-2(as P2O5),220.30 kg·hm-2(as K2O),0 kg·hm-2(as CaO),and 44.33 kg·hm-2(as MgO),respectively.关键词
