原子能技术在农业上的另一个重要用处,是用放射性同位索作为示踪原子来帮助农业增产。其用处现在已有几千项之多,其中对北美农业有广泛影响的几项是:(一)示踪原子显示出肥料不仅可以从根部吸收,而且可以从叶和皮层吸收。从而创造了肥料喷撒到枝叶上新的施肥方法。(二)示踪原子显示,植物体内50%— Another important agricultural use of nuclear energy is the use of radiolabels as tracer atoms to help increase agricultural output. There are now thousands of its usefulness, of which several have a broad impact on North American agriculture are: (a) tracer atoms show that the fertilizer can not only absorb from the roots, but also from the leaves and cortex absorption. Thus creating a new fertilizing method of spraying fertilizer onto foliage. (B) tracer atom shows that plants in vivo 50% -
