【目的】探明抗寒种衣剂包衣处理对常温和低温环境下水稻发芽和成苗的影响．【方法】以湘早籼31号（常规稻）和Y两优1号（超级杂交稻）为材料，在华南农业大学研制成功的多成分、多功能的“齐苗快”浸种剂的基础上，结合黑龙江垦区常用拌种剂，添加杀菌杀虫剂、粘合剂等物质配备成种衣剂，设置未包衣浸种催芽（ CK）、干种包衣（ A）和浸种包衣（ B）共3种处理方式，研究了抗寒种衣剂包衣处理对不同基因型水稻的发芽和成苗特性的影响．【结果和结论】结果表明：包衣处理后，在自然环境正常温度下，稻种发芽时间延长，但对种子发芽率有提高作用，对Y两优1号，干种包衣和浸种包衣处理分别比对照提高11.10％和16.55％，湘早籼31号分别提高了30.83％和37.68％；在低温环境下，稻种幼苗受到低温侵害后成苗率降低，但包衣处理相较于未包衣处理提高了稻种的成苗率，其中又以浸种包衣处理的成苗率最高，湘早籼31号和Y两优1号分别为54.95％、74.10％，相较于对照（ CK）分别提高了120.24％、127.30％．同时，种衣剂包衣处理（ A、B）提高了稻种秧苗受芽期低温侵害后的存活率，浸种包衣（ B）处理提高了“二叶一心”期低温侵害后稻种秧苗的存活率．

英文摘要：

[Objective]The experiment was conducted to study the influences of coating treatment with cold indicated seed-coating agents on the rice seed ’ s germination at a normal temperature and low tem-perature.[Method]No.31 Xiangzaoxian （conventional rice） and No.1 Y Liangyou （super hybrid rice） were chosen as the rice seed material using the soaking agent ‘Qimiaokuai ’ developed by South China Agricultural University , combined the seed dressing agents commonly used in Heilongjiang Reclamation , and added germicidal agents , pesticides , adhesives with other substances mixed as the seed coating a-gent.Three treatments included soaking and accelerating germination （CK）, coated without soaking（A） and coated after soaking （ B） .The effects of coating treatment on different genotypes rice seed ’ s germina-tion and seedling quality were studied in this paper .[Result and conclusion]The results showed that for coated treatment , at a normal temperature , the seed germination time lengthened , but germination rate＆amp;nbsp;increased.The germination rate of No .1 Y Liangyou coated without soaking and coated after soaking treatment respectively increased by 11.10%and 16.55%compared with control , and No.31 Xiangzaox-ian increased by 30.83%and 37.68%, respectively .Under low temperature conditions , the germination decreased because of the cold infestation .Coating treatment improved the seedling rate of rice , and the rice which were coated after soaking （ B） had the highest seedling rate , with No.31 Xiangzaoxian and No.1 Y Liangyou being 54.95% and 74.10%, respectively.Contrasted with control, those were im-proved by 120.24%and 127.30%, respectively.Coating treatment （ A, B） improved the survival rate of seedlings after low temperature treatment at the bud stage , and coated after soaking treatment （ B） im-proved the survival rate of seedlings after low temperature treatment at the two-leaf stage .
