摘  要:
本文研究了镜面柿果实膨大期追施尿素后叶片生理指标及果实品质的变化。研究发现追施尿素促进叶片中叶绿素、蛋白质及氨基酸含量的增加。其中400 g高氮施肥的效果表现最好。此外,施肥后果实可溶性糖、可溶性酸、Vc含量及单果重均有不同程度的提高。

摘  要:
Experiment was conducted to study the changes of leaf nitrogen metabolism and fruit quality after fertiliza-tion during the fruit swelling of Jingmian persimmon.The result showed that chlorophyll,protein contents and amino acid contents were increased after fertilization.The best result was obtained by nitrogen treatment of 400 g urea.Besides this,the treatment with fertilization increased the contents of the soluble sugar,the soluble acid and Vc,and increased the weight of single fruit in different degrees.
