The Effect of Different Nitrogen Application Rates on the Yield and Quality of Peach Fruit
In order to explore the appropriate application rate of peach trees in Kaiyang county,and improve the comparative benefits per unit area,an experimental study was onducted on four fertiliza-tion treatments.Results showed that there was no significant difference in fruit yield among different treatments,and functional relationship between yield per unit area and nitrogen application amount Y=1 061.73+106.957 X-6.755 X2,R=0.882.There was a high correlation between fruit yield per unit area and nitrogen application amount,showing a peak function model,comply with the law of nutrient remuneration.With the increase of nitrogen fertilizer application,the total acidity of peach fruit increased,while the content of soluble sugar and soluble solids decreased.When 22 500 kg/hm2 green manure was returned to the field and 94.5 kg/hm2 pure nitrogen was applied to peach orchard,the yield of fruit was appropriate and the comprehensive quality was the best.
