摘　　要：为了提高樱桃的产量和品质,增加经济效益,研究了不同氮肥用量对中国樱桃生长和品质的影响。结果显示,不同氮肥用量均促进了中国樱桃叶片生长,其中0.50 kg/株氮肥处理较对照显著提高了花后2周叶片长、叶片宽和叶片SPAD值。0.50 kg/株氮肥处理显著提高了花后4周叶片重量。此外,0.50 kg/株氮肥处理对果实单果重、可溶性固形物含量、固酸比、VC含量起到促进作用。综合上述分析,确定0.50 kg/株氮肥是最佳氮肥施肥量。In order to improve the yield and quality of cherries and increase economic benefits,the effects of different nitrogen fertilizer application rates on the growth and quality of Chinese cherries were studied.The results showed that different nitrogen application rates all promoted the growth of Chinese cherry leaves,compared with the control,0.50 kg/plant nitrogen fertilizer treatment significantly increased leaf length,leaf width and leaf SPAD value at 2 weeks after flowering.The 0.50 kg/plant nitrogen fertilizer treatment significantly increased the leaf weight at 4 weeks after flowering.In addition,0.50 kg/plant nitrogen fertilizer treatment promoted the single fruit weight,soluble solids content,solid-acid ratio,and VC content of the fruit.Based on the above analysis,0.50 kg/plant nitrogen fertilizer was determined to be the best nitrogen fertilizer application rate.
