摘　　要：在新疆阿克苏地区,以3a生灰枣为试材,自5月10日至7月10日在枣树展叶期,对新生枣头进行7次摘心,研究摘心对枣树枝条生长及产量的影响。结果表明:每个当年新生枣头保留2～3个二次枝能使枣头一次枝粗度平均达到1.2cm,显著高于对照的0.9cm。吊果比达到0.96～0.99,株产达到0.40～0.46kg,比对照增加0.33～0.27kg。可见摘心于抑制枣树枝条加长生长,促进加粗生长,提高枣股质量,抽生木质化枣吊,形成大量花芽,提高坐果率和产量。With 3 years old ＇Huizao＇ as materials in Akesu,Xinjiang,from May 10 to July 10 in jujube leaf stage,studied 7 pinching on fresh branches on the influnce of jujube tree growth and yield.The results showed that retain two to three branches of secondary branches on present year grow branch could made primary branch reached 1.2 cm,significantly higher than the control of 0.9 cm.Hanging fruit ratio reached 0.96 to 0.99,plant yield reached 0.40-0.46 kg,compared with the control increased 0.33-0.27 kg.Pinching jujube tree branches inhibited longer growth,and promote thick growth,improved the quality of date stock,pumping lignification dates hanging,could form a large number of flower buds to improve fruit set and yield.
