最后选用得到的最优参数配合对隆安优1号进行综合处理，并做发芽对比试验，结果表明综合处理后Ⅰ级种子的平均发芽率和幼苗平均生长高度与对照组（CK）对比分别提高了12.12%～15.58%和14.08%～25.51%，发芽指数和活力指数提高了18.28%～21.8%和35.74%～51.16%，且在 =0.05水平上存在显著性差异。

Finally selects the most superior parameter coordination which obtains to Long'anyou 1 to carry on synthesis processing, and does the germinates trial to comparatived, after finally indicates synthesis processing, The first level seed's average germination percentage and the seedling grew equally height and contrasting the control group (CK) enhanced 12.12%~15.58% and 14.08%~25.51% separately, germinated the index and the vitality index enhanced 18.28%~21.8% and 35.74%~51.16%, and At the 0.05 level, the population means are significantly different.Keywords: high voltage electric field; paddy rice seed;dielectric separation; germination test引言种子是农业生产中最基本的特殊生产资料，是农业发展的基础和先导。
