江苏丰县地区丰县"富士"苹果生产园叶片矿质营养元素适宜值的研究
Appropriate Content of Leaf Mineral Element in 'Fuji' Appleorchards of Fengxian,Jiangsu Province
摘要
Abstract
To establish a suitable method for the quality evaluation of 'Fuji' apple in Jiangsu Fengxian County area,and obtain the optimum content of leaf mineral elements in this area,a theoretical basis was pro-vided for leaf nutrition analysis,fertilization and construction of high quality apple orchard in the old course of the Yellow River in Jiangsu Province.In this experiment,the content of 9 mineral elements in leaves and 7 quality characteristics in fruits were analyzed.At the same time,the relationship between 'Fuji' leaf mineral elements and fruit quality of'Fuji' apple in Jiangsu Fengxian County area was explored by correlation analysis and principal component analysis.The results showed that the cumulative contribution rate of the first 4 princi-pal components reached 85.12%.The first principal component mainly reflected the hardness,soluble solids, and soluble sugar;the second principal component reflected the single fruit weight,fruit shape index,and titrat-able acid information;the third principal component mainly reflected the titratable acid,soluble sugar,and Vc information.The fourth principal component mainly reflected the fruit weight and fruit shape index information. The single fruit weight,titratable acid and Vc were very important in the quality evaluation of 'Fuji' apple, and the suitable values of mineral elements in the leaves of'Fuji' apple in Jiangsu were obtained:N(14.93-17.74 g/kg),P(0.77-1.02 g/kg),K(10.29-13.43 g/kg),Ca(12.45-17.88 g/kg),Mg(2.52-4.00 g/kg), Fe(274.15-493.68 mg/kg),Mn(40.82-98.85 mg/kg),Cu(85.36-354.26 mg/kg),Zn(39.55-83.76 mg/kg).关键词
