不同施氮量对春玉米早衰的影响
Effects of N Application Rates on Early Senescence of Spring Maize
摘要
Abstract
This experiment was conducted to study the effect of different N application rates on early senescence of spring maize, Spring Maize was used as the tested crop in a pot experiment to study the effect of different N application rates on early senescence. The chlorophyll content was the lowest and membrane structures have been disintegrated in no N treatment and caused early senescence. When the proper increase of the N rates could enhance yields by more than 35.9% and the chloroplast ultrastructure was inproved. There was close relationship between early senescence and N nutrition. So the reasonable amount of nitrogen was the effective method to prevent early senescence and ensure that maize yields.关键词
