Effects Of Proportioning Fertilization Of N, P And K On The Quality And Mineral Elements Content Of ’YuluXiang’ Pear

This study taking’Yuluxiang’ Pear as the test materials studied the different ratios of fertilizers in order to provide scientific evidence for producing high-quality of this pear. It also had a significant meaning for promoting of ’Yuluxiang’Pear. The result of this study showed that the quality of the fruit was best when the ratios N, P and K were222:322:202. The content fruit of Fe and Mn was not affected by applying N, P and K. Applying the fertilizers of N, P and K were0kg,0kg and0kg, the fruit content of Zn reached its summit. Applying N, P and K were Okg,0.6kg and0.9kg when the fruit content of Ca reached its summit. Applying N, P and K were Okg,0.6kg and Okg when the fruit content of Mg reached its summit. The fruit content of Zn decreased by applying increasingly fertilizers of P and K. The fruit content of Ca decreased by applying increasingly the fertilizer of N. The fruit content of Mg increased by applying solely fertilizer of P. The effecting fertilizer of P on fruit content of Mg was decreased by applying increasingly the fertilizer of N, while the effecting fertilizer of k on fruit content of Mg was increased by applying increasingly the fertilizer of N.
