土壤养分对'富士'苹果品质的影响
Effects of soil nutrients on the quality of'Fuji'apple:Based on a survey of apple orchards in 6 counties in 3 provinces
摘要
Abstract
To study the effects of different soil nutrients on the quality of'Fuji'apples,seven quality indicators of'Fuji'apple and six indicators of soil nutrient factors in orchards were selected and measured by taking'Fuji'apples and soils from 46 mature orchards in Shandong,Shanxi and Shaanxi provinces as study materials.The correlation analysis,partial least squares and multiple linear regression were used to screen the most important soil nutrient factors affecting the quality of'Fuji'apples and establish a regression equation between soil nutrient factors and the quality of'Fuji'apples.The results showed that:1)Soil alkaline dissolved nitrogen content was significantly and positively correlated with coloring area,soluble solids content and acid-fixing ratio;Effective phosphorus content was significantly and positively correlated with fruit firmness and acid-fixing ratio;effective iron content was significantly and positively correlated with coloring area,soluble solids content,acid-fixing ratio and fruit shape index;pH was significantly and negatively correlated with coloring area,soluble solids and acid-fixing ratio,and highly and significantly correlated with titratable acid content.significant positive correlation with titratable acid content.2)The soil nutrient factors affecting apple quality(in descending order of impact)are as follows:Single fruit quality,pH and available calcium;Fruit shape index,available iron and pH;Coloring area,available iron,pH and alkali-hydrolyzed nitrogen;Fruit firmness,available phosphorus,available potassium and pH;Soluble solid content,available iron,pH and alkali-hydrolyzed nitrogen;Titratable acid content,pH,available iron and alkali-hydrolyzed nitrogen;Effects of solid acid ratio,pH,available iron and alkali-hydrolyzed nitrogen.On this basis,the regression equation of'Fuji'apple quality was established,and the positive and negative effects on fruit quality and the degree of influence could be obtained according to the regression coefficient of soil nutrient factors.关键词
