水稻生长不要冷落硅和锌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配合，而相应忽略了硅、锌等元素的施用。事实上水稻是吸收硅较多的作物，一般茎叶中含有二氧化硅１０％～２０％，水稻体内硅酸含量约为氮的１０倍，磷的２０倍左右。水稻缺硅，容... Do not leave the rice growth of silicon and zinc In formula optimization of rice fertilization, people often attach great importance to a large number of elements such as nitrogen and phosphorus fertilizers with, while ignoring the silicon, zinc and other elements of the application. In fact, rice is a plant that absorbs more silicon. Generally, stems and leaves contain 10% -20% of silica. The content of silicic acid in rice is about 10 times that of nitrogen and about 20 times of phosphorus. Rice lack of silicon, capacity ...
