摘　　要：以农大4号欧李植株为试材,对其新梢进行不同留枝量试验,分别设定留枝量为2个、4个、6个、8个、10个,以不修剪新梢作为对照,研究不同留枝量对欧李植株生长发育、叶绿素相对含量、果实品质和产量的影响。结果表明,留枝量为6个,枝条长度、枝条直径、果实可溶性固形物、果实维生素C含量、果实维生素D含量、单果重、百粒重、单株产量和单位面积产量均较高。综合对比各项指标,留枝量为6个的处理适合欧李枝条整形修剪。This study used the"Nongda No.4"Cerasus humilis plant as the test material to conduct different branch retention experiments on its new shoots.The branch retention amounts were set to 2,4,6,8,and 10,respectively.The effects of different branch retention amounts on the growth and development,relative chlorophyll content,quality,and yield of Cerasus humilis plants were studied with untrimmed new shoots as the control group.The results showed that when the number of branches was 6,the length,diameter,soluble solid content,vitamin C,vitamin D,single fruit weight,100 grain weight,yield per plant,and yield per unit area were all relatively higher.Based on a comprehensive comparison of various indicators,it was concluded that a treatment with 6 remaining branches is suitable for pruning and shaping the branches of Cerasus humilis.
