近年来，玉溪地区小麦生产上零星出现小麦“稳而不实”现象，通过采样测定分析，初步认为可能与缺乏某种微量元素有关。本文通过室内水培缺素对比试验，探讨小麦缺乏硼锌铜镜等4种营养元素对其生长的影响，同时诱发了小麦植株表现相应的缺素症，可为田间小麦缺素症的营养诊断提 In recent years, the phenomenon of “steady but not real” wheat sporadically appeared in the wheat production in Yuxi area. According to the sample analysis, it is preliminarily thought that it may be related to the lack of certain trace elements. In this paper, we compared the effects of four nutrient elements, including boron, zinc and copper mirror, on the growth of wheat plants by inducing the lack of boron, zinc and copper mirror in laboratory, and also induced the corresponding deficiency of wheat plants, which could provide nutrition diagnosis for the deficiency of wheat mention
