| 摘 要： | 研究了不同的氮素处理对设施条件下油桃叶片质量、果实品质的影响。试验结果表明：施用适量的氮素可以使桃树叶片变厚，比叶重提高，叶绿素含量及光合能力均有显著提高；适量的氮素会使果个增大，平均单果重增加，可溶性固形物含量及酸度提高。从产量及品质综合考虑，对于3—4年生油桃来讲，每年以株施尿素300—600克左右为宜。

| Abstract: | The trees of necfarine variety Shuguang were used as materials to study the hects of nitrogen application on the leaf auality and fruit deuelopment.The rescclts shoued that proper nitrogen applications could signiticantly increase the leaf thickeness specific leaf weight,chlorophyll contents and photosynthetic rate,The fruit size,mean single truit weight,soluble solid contents and total acid concentration ot fruits were also increased.Comprehensively considering the yield and quality of nectarine,300-600g each tree should be used for each tree per year. |
