不同钼源对油菜和冬小麦光合作用和花粉发育的影响

发布时间：2021-03-23 16:49

　　钼是农作物的必需微量元素。中国钼缺乏耕地约4467万公顷,占耕地总面积的46.8%。近年来,含钼纳米材料在农业中的应用受到广泛关注。本文以普通钼酸钾和钼酸铵做为比较材料,研究了纳米钼酸钾对冬小麦和油菜光合作用及花粉发育的影响。得到的结果如下:1,叶片施用纳米钼酸钾和普通钼肥能增加冬小麦和油菜的钼含量,但叶面纳米钼酸钾具有更好的处理效果。与不施钼肥的对照相比,叶面纳米钼酸钾处理的冬小麦叶片,穗状花序和种子中的钼含量显着增加了637%,180和135%,钼的累积量增加了877%,239%和248%,而叶面施用普通钼酸钾处理使冬小麦叶片,穗状花序和种子中的钼含量增加了488%,137%和120%,钼的积累量增加了656%,151%和186%;与对照组相比,叶面纳米钼酸钾处理使油菜茎,颖花和种子的钼含量分别增加了114%,94%和210%,钼的积累量增加了130%,118%,叶面施用普通钼酸钾处理的油菜菜杆茎,颖花和种子分别增加94%,74%和153%,钼的积累分别增加102%,97%和223%。一般而言,叶面施用钼肥后,叶片钼含量以及积累的效果冬小麦要优于于油菜。2.叶片施用纳米钼酸钾和普通...
