| 摘 要： | 为明确小麦杀雄荆SQ-1喷施后遇雨及雨后复喷对小麦的杀雄效果及异交结实率的影响,采用人工模拟降雨冲洗SQ-1和重复喷药喷水处理，研究了不同处理对SQ-i的杀雄效果以及异交结实率的影响，结果表明：（1）杀雄荆SQ-1在雨前2h喷施便可以被植株吸收，达到良好的杀雄效果；（2）雨后复喷SQ-1可达到完全杀雄效果，但喷施次数越多异交结实率越低。

| Abstract: | To study the effect of CHA SQ-1 under the rainy day or the bad weather conditions,the seed sets rate of repeat spraying after raining in the functional effect of CHA SQ-1 and the ratio of open pollination in the simulated rainfall in different disposal and spraying CHA were analyzed in different treatment.The result was as follows:(1)SQ-1 was absorbed completely in 2 hours before the rain and have perfect effect of inducing male sterility.(2)SQ-1 harmed the vigor of pistil in dose of 5 kg/ha in some degree and the wheat self seed set rate decreased distinctly. |
