不同鉬源對油菜和冬小麥光合作用和花粉發(fā)育的影響

  鉬是農(nóng)作物的必需微量元素。中國鉬缺乏耕地約4467萬公頃,占耕地總面積的46.8%。近年來,含鉬納米材料在農(nóng)業(yè)中的應(yīng)用受到廣泛關(guān)注。本文以普通鉬酸鉀和鉬酸銨做為比較材料,研究了納米鉬酸鉀對冬小麥和油菜光合作用及花粉發(fā)育的影響。得到的結(jié)果如下:1,葉片施用納米鉬酸鉀和普通鉬肥能增加冬小麥和油菜的鉬含量,但葉面納米鉬酸鉀具有更好的處理效果。與不施鉬肥的對照相比,葉面納米鉬酸鉀處理的冬小麥葉片,穗狀花序和種子中的鉬含量顯著增加了637%,180和135%,鉬的累積量增加了877%,239%和248%,而葉面施用普通鉬酸鉀處理使冬小麥葉片,穗狀花序和種子中的鉬含量增加了488%,137%和120%,鉬的積累量增加了656%,151%和186%;與對照組相比,葉面納米鉬酸鉀處理使油菜莖,穎花和種子的鉬含量分別增加了114%,94%和210%,鉬的積累量增加了130%,118%,葉面施用普通鉬酸鉀處理的油菜菜桿莖,穎花和種子分別增加94%,74%和153%,鉬的積累分別增加102%,97%和223%。一般而言,葉面施用鉬肥后,葉片鉬含量以及積累的效果冬小麥要優(yōu)于于油菜。2.葉片施用納米鉬酸鉀和普通...
