在水稻杂交技术中,目前普遍采用的是温汤去雄法。但是,这种方法要求父母本花时相遇时才能应用,也就是说,经温汤去雄后的母本稻穗要等到父本稻穗开花裂药时方能授粉。如果遇到不适宜水稻开花的天气,比如,天阴、低温、父本推迟开花时,授粉工作就难以进行。当天晴高温时,稻穗开花多而集中,利于杂交。然而.此时对田间操作的杂交工作者来说却十分辛苦,如果风大,还会影响花粉采集与授粉工作进行。怎样才能使温汤去雄法不受时间和天气的限制而应用得更有效更方便呢?这就要设法使父本稻穗在母本温汤去雄的同时开花。
In rice hybridization technology, currently used is warm soup to male method. However, this method requires parents to use the time to meet, that is to say, after the Wen Tang Tang male maternal rice to wait until the parent panicle blossom pollinating only pollination. If you encounter unfit for rice flowering weather, for example, overcast, low temperature, fertility delay when fertility parents, pollination difficult to carry out. The day when the temperature is high, the flowering of rice and more concentrated, conducive to hybridization. However, cross-fertilization workers in the field are very hard working at this time, and if the wind is too large, pollen collection and pollination will also be affected. How to make the warm soup to the male method is not subject to the limitations of time and weather and more effective and more convenient to apply it? This should try to make the male parent rice warm soup at the same time male and female flowers.
