Ion beam implantation technique, a biophysical technology, has the characteristics of slight phys- iology injury, wide mutation spectrum, high mutation frequency and so on. The interaction between ion beam and or- ganism is a biophysical technology possessing a independent copy-righted product in China, the Chinese scientists have discovered the biological effect of ion beam implantation in the 1980s, and applied this principle into plant muta- tion breeding. In this article, we mainly summarized the action principle of organisms by ion beam and its application, including on plant breeding, microorganism varieties improvement and genetic modification, in conclusion, we still sumed up the problems existing in this investigation field by
