| 摘 要： | 取湖北省几个主要麦产区土壤盆栽，研究小麦施钼效果与土壤Ｎ、Ｍｏ水平的关系。结果表明：小麦施钼效果与施Ｎ水平和土壤钼值密切相关，而与土壤有效钼含量相关不显著。在高Ｎ水平下施钼小麦增产显著；低Ｎ下施钼增产不稳定。用钼值指导小麦施钼明显优于传统的有效钼法。由此提出施Ｎ水平和土壤钼值是小麦施钼的两个重要有效条件。

| Abstract: | Seven upland soils, which were collected from main wheat producing areas in Hubei Province, were utilized to investigate the efficiency of wheat Mo application and the relationship of soil N and Mo levels with pot culture method. The main results were as follows: there was a close relationship between the effect of Mo fertilizer application and N fertilizer levels, and Mo value. There was no significant correlation between the effect of Mo fertilizer and the content of soil available Mo. At high N level Mo fertilizer remarkably raised grain yield, while at low N fertilizer level, the response was instable. Soil Mo value was obviously superior to the traditional soil available Mo method in wheat Mo application. N fertilizer level and soil Mo value might be two important factors which would influence the effect of Mo fertilizer applying to wheat. |
