用Ｒ型浸种剂处理水稻种子，可提高种子及根系活力，提高幼苗移栽的成活率，增强根系对Ｎ、Ｐ、Ｋ等养分的吸收。幼苗的根系脱氢酶、植株过氧化氢酶活性明显提高，茎叶中叶绿素及游离氨基酸含量也比对照增加，使水稻的有效总数及穗位数分别比对照增加７．８％～２６．７％和２．３％～１０．６％，仔粒产量增长８．１６％～２２．３７％（盆栽）和１２．６％～１５．１％（大田）。３种浸种剂增产效应的顺序是：Ｒ＿１、＞Ｒ＿３＞Ｒ＿２。 Treatment of rice seeds with R-type soaking agent can improve seed and root activity, increase seedling transplanting survival rate, and enhance the root’s absorption of N, P, K and other nutrients. The root dehydrogenase and plant catalase activities of seedlings were significantly increased, and the content of chlorophyll and free amino acids in stems and leaves also increased compared with the control, which increased the effective total number of rice and ear position by 7.8% ~ 26.7 % And 2.3% ~ 10.6% respectively. The yields of earnails increased 8.16% ~ 22.37% (pots) and 12.6% ~ 15.1% (field). The order of increasing effect of three kinds of soaking agent is: R_1,> R_3> R_2.
