摘　　要：为探索开阳县桃树适宜的施氮量,提高单位面积比较效益,本研究设置了4个不同的氮肥处理,探究不同施氮量对桃子产量以及品质的影响。结果表明,各处理间的果实产量差异不显著,单位面积产量与施氮量间的函数关系:Y=1061.73+106.957 X-6.755 X^(2),R=0.882,桃树单位面积果实产量与施氮量间存在高度相关性,呈峰型函数模型,符合养分报酬规律。随着氮肥施用量的增加,桃子果实中的总酸度呈增长趋势,而可溶性糖和可溶性固形物含量均呈下降趋势。桃园以22500 kg/hm^(2)绿肥还田,并施用纯氮94.5 kg/hm^(2)的条件下,果品产量适宜、综合品质最优。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 fertilization 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=1061.73+106.957 X-6.755 X^(2),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 22500 kg/hm^(2)green manure was returned to the field and 94.5 kg/hm^(2)pure nitrogen was applied to peach orchard,the yield of fruit was appropriate and the comprehensive quality was the best.
