用微波、恒温水浴、恒定直流磁场用结合的方法对水稻种子进行四因素二水平的正交试验，结果表明：微波热击、磁场处理相结合可显著提高种胚呼吸强度和种子活力，不同方法处理的发芽势芽长，与种胚呼吸强度呈显著正相关。
The results of orthogonal experiment of rice seeds using microwave, constant temperature water bath and constant DC magnetic field combined with four factors and two levels showed that microwave heat shock and magnetic field treatment could significantly improve the respiration rate and seed vigor of seed embryo. Different methods The length of germinated shoots treated was significantly and positively correlated with the respiration intensity of seed embryo.
