根外施肥对中秋酥脆枣幼树营养生长的影响

摘要

In order to analyze the influences of different exoroot fertilization treatments on vegetative growth of Zhongqiusucui Jujube saplings,exoroot fertilization experiment of Zhongqiusucui Jujube saplings was carried out by 19 treatments of 2 methods and 3 fertilizers.The results indicate that appropriate exoroot fertilization treatment can significantly promote vegetative growth of plant.The better fertilization treatments in the experiment are smearing stem using 5％ KH2PO4,spraying foliage using 0.5％ urea,spraying foliage using 0.5％ amino acid fertilizer and spraying foliage using 0.5％ KH2PO4.%为了解不同根外施肥对中秋酥脆枣幼树营养生长的影响,采用2种方法、3种肥料共19个处理对中秋酥脆枣幼树进行了根外施肥试验.结果表明,适当的根外施肥可明显促进植株的营养生长,其中以涂干5％KH2PO4、喷叶0.5％尿素、喷叶0.5％氨基酸和喷叶0.5％ KH2PO4处理的综合肥效较好.
