以超级稻千重浪2号和普通稻秋光为试材，采用盆栽方法，模拟砷污染农田，设置4种砷胁迫质量浓度，即0，20，40，60 mg/kg。砷以Na3AsO4·12H2O的形式加入。试验结果表明：低质量浓度砷（20 mg/kg）在分蘖期对秋光生长有刺激作用，具体表现为株高、分蘖数和地上部分干质量高于对照；低砷处理在分蘖期对千重浪2号不存在刺激效应。同时砷胁迫对稻米的品质也产生了一定的影响，整精米率和蛋白质含量明显下降，碱消值增加，垩白米率、垩白度下降，直链淀粉含量无显著变化。

The experiment uses Qianchonglang 2 and Qiuguang as tested material .The two kinds of rice are grown in different pots,added four kinds of concentrations of Na 3AsO4· 12H2O (0,20,40,60 mg/kg),to simulate the paddy field contaminated by arsenic .The low concentration (20 mg/kg) of arsenic stimulates the plant growth of Qiuguang rice .The Qiuguang rice ,under the low arsenic stress ,has higher plant height ,more tillering and dry-matter than the contrast one .But the stimulation is not significant in Qianchonglang 2.The low arsenic concentration stress makes different effects between the ordinary rice and the super rice .The influences of arsenic on rice quality are tested.The contents of protein,head rice rate,chalky rice rate and chalkiness degree decreased and alkali sprea-ding value increased .The contents of amylase show no different .
