【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更多还原

【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.更多还原
