在水稻的优化配方施肥中,人们往往十分重视氮、磷、钾等大量元素肥料的施用,而忽视了硅、锌等元素的施用。事实上,水稻是吸收硅较多的作物,水稻体内硅酸含量约为氮的10倍、磷的20倍。水稻缺硅,容易导致茎杆软弱,倒伏和感染病害。前期缺硅,使水稻穗数减少,后期缺硅则小穗数减少。水稻优质高产没有保障。而给水稻 In the optimization of rice fertilization, people often attach great importance to the application of nitrogen, phosphorus, potassium and other large elements of fertilizers, while ignoring the silicon, zinc and other elements of the application. In fact, rice is a plant that absorbs more silicon. The content of silicic acid in rice is about 10 times that of nitrogen and 20 times that of phosphorus. Rice lack of silicon, easily lead to stalk weakness, lodging and infection disease. Si lack of early rice to reduce the number of panicles of rice, the latter lack of silicon is reduced spikelets. Rice is not guaranteed high quality and high yield. And give rice
