草莓果实品质及其与土壤养分的相关性分析
Analysis on Fruit Quality of Strawberry and Its Correlation with Soil Nutrient
摘要
Abstract
In recent years,strawberry industry in our country has developed very fast.Dandong 99 Strawberry(Fragaria×ananassa Duch.),as the main strawberry variety in Liaoning Province,has high edible value and economic value.In order to understand the soil nutrient status and its influence on strawberry fruit quality in Liaoning Province,and explore the key soil factors affecting strawberry fruit quality,strawberry fruits and surface soil(0-20 cm)were collected from 40 strawberry farms in Dandong,Benxi and Shenyang,and the fruit quality indexes and soil physicochemical properties indexes were detected.The quality of strawberry fruit was evaluated by principal component analysis,and the comprehensive ranking was conducted by principal component score.The correlation between strawberry fruit nutrients and soil nutrients was explored by correlation analysis.The results showed that there was wide variation in fruit traits among individuals,with the coefficient of variation ranging from 4.67%to 56.02%,and the coefficient of variation of fructose was maximum.By principal component analysis,3 principal components were extracted,and the cumulative contribution rate was 60.25%.Twenty strawberry farms with higher comprehensive scores were selected.Generally,the soils of 40 strawberry farms were slightly acidic,with excess contents of Alkaline-N and Olsen-P,suitable contents of Organic matter,Available-K.The soil indexes for improving strawberry flavor were Alkaline-N,Olsen-P,Available-K and Available B.The soil indexes for improving appearance quality of strawberries were Organic matter,Exchangeable calcium and Exchangeable magnesium.关键词
