调查以农十四师224团直播建园的骏枣为试材,采用圆柱形、小冠疏层形(永久株)、小冠疏层形(永久行)、三主枝中干形4种树形方式,研究了不同树形对枣树结构发育、果实产量构成和品质的影响。结果表明:4种树形树冠大小差异大,小冠疏层形树冠最大;不同树形的单株枣股数、枣吊数、每个枣吊枣数、枣果重有所差别,这些是构成产量 The investigation was conducted on jujube jujube cultivated with 224 farms of the Nongzhong Division by using the methods of cylindrical, small sparse layer (permanent), small sparse layer (permanent) and dry stem Tree shape, studied the different tree shape jujube tree structure development, fruit yield formation and quality. The results showed that there were big differences in crown size among the four kinds of tree crowns and the largest canopy sparse layer crown. The numbers of jujube, jujube, jujube and jujube in different tree forms were different Constitute the output
