氮、磷、钾配比施肥对玉露香梨果实品质的影响
Effects of N, P and K proportioning fertilization of on the quality of Chinese pear ‘Yuluxiangli’
摘要
Abstract
[Objective]This study studied the effects of different proportion fertilization on fruit quality in order to provide scientific evidences for producing high quality pear'Yuluxiangli'.[Methods]Fruit quality index of'Yuluxiangli'were measured in 14 different fertilization modes.The data were analyzed using principal component with SPSS software.[Results]Compared with no fertilizer (treatment 14),different ratio of NPK fertilizer could effectively promote the pear vitamin C,soluble solids content and soluble sugar content.The principal component analysis (PCA) results showed that the cumulative contribution proportion of the former four principal components was 89.34％.They completely met the needs for analyses.By each eigenvector obtained,factors determining the size of the former four principal component were mainly soluble sugar,stone cells,hardness and soluble solids contents.Among 14 different fertilization modes,the comprehensive score of fruit quality from high to low ranking were treatment 4,1,6 2,8,9,5,11,7,10,12,3,13 and 14.[Conclusion]In brief,the best effect of different NPK fertilizer ratios was treatment 4 (N∶P∶K=1.0∶0.4∶0.6).关键词
