摘要
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。
The results of treating rice seed with R types seed soaking agent show that it can in- crease seed vigour and root system vigour promotes plant emergence , tiller and root systemgrowth,increase absorbtion of N、P、K , hydrogen peroxidase activity ,root system dehydro- genase activity,content of chlorophyll and amino acid in the rice were higher them that of CKthus unit area yield was increased,and mean increased by 8.16%~22.37%(pot experiment)and 12.6%~15.1%(field experiment)。
