【Abstract】 s:The wheat seeds are pretreated by means of super low energy ionic beams(500eV).Field planting and indoor trial raising as well as the electrophoreses analsis of isodynamic enzyme of the wheat have shown:isodynamic enzyme belt is changed,and the effective wheat ear numbers as well as the output per mu are also evidently increased. Maximum increase in production in small scale test can be up to 21 8%.更多还原
