| 摘 要： | 以滴灌为条件设置不同水肥处理,分析不同施肥、灌溉水平对灰枣果实中矿质元素含量的影响.结果表明:在灌水量中等水平条件下,增施氮肥能促进枣果对N、K素的吸收和积累,施入量过高则会抑制P素的吸收;在施入氮肥为中等水平条件下,增加土壤水分能促进枣果对P素的吸收和积累,抑制N、K素的吸收;增加土壤水分和氮素含量均可提高灰枣果实中矿质Fe、Zn、Cu、Ca和Mg的含量,Mn的含量随施入土壤中氮肥量的增加而减小.

| Abstract: | The different treatments of water and fertilizer under drip irrigation,were designed to analyze the content of mineral elements in fruit of Huizao under coupling of water and N.The results showed that,under the condition of moderate water,it could promote the fruit of Huizao to assimilate and accumulate N,K with fertilizer N increasing,but it could restrain assimilating P.Under the condition of moderate N it could promote the fruit of Huizao to assimilate and accumulate P with soil water increasing,but it c... |
