一、锰在作物体内的含量、分布和生理作用作物干物质中含锰量为十万分之几至千分之几.不同器官中含锰量不同,一般是叶多于茎,茎多于种子,地上部多于根部.作物体内的光合作用、氮的转化、碳水化合物的转移以及一些氧化还原过程都与锰有关.铁锰之间的浓度比也很重要,据一些材料介绍,各种作物适宜的锰铁浓度比小麦为1:2.5,大豆1:1.5～3.5,
First, the content of manganese in the crop body, distribution and physiological role of dry matter in crops containing manganese content of a few thousandths to a few thousandths of different organs with different manganese content, usually leaves more than stems, stems more than The seeds, the aerial part is more than the root part.Photosynthesis, nitrogen transformation, carbohydrate transfer and some redox processes in the crop are related to manganese.The concentration ratio between Fe and Mn is also very important. According to some materials, Crop suitable ferromanganese concentration than wheat 1: 2.5, soybean 1: 1.5 ~ 3.5,
