Effect of Molybdenum and Boron on increasing alfalfa seed yield

摘要

Although the content of microelements is low in plants, they play a role in translocation and energy exchange in metabolism, and have an important influence on crop yield (Guoxiao,etc.,2006 ;Chang Yao‐hong,2007 ; Hu Ai‐tang,2003).Different concentrations of borax and ammonium molybdate were sprayed at early florescence,squaring, and florescence of alfalfa in this study, and the effect of boron and molybdenum on yield of alfalfa seed was measured.
