乙烯利和三嗪二酮都是目前我国生产的较好的小麦杀雄剂,用乙烯利4000ppm+二酮4000ppm 混合液,从花粉母细胞形成-花粉双核期喷施,比单一药剂喷施药害较轻,有效喷药期长,不育率可达80～90%,雌芯受精能力亦不受影响。小麦与桥梁品种的杂种,经化学杀雄后在隔离区中与黑麦自然授粉,可获得大量的杂种。这不仅可节省人力和时间,而且还可利用化杀后保留的部份自交结实率,进行小麦与黑麦可杂交的新桥梁品系的选育。 Ethephon and triazine dione are currently produced in our country better maleicide, with ethephon 4000ppm + dione 4000ppm mixture from the pollen mother cells formed - pollen dual-core spray, spraying than single drug injury than Light, effective spraying period, the infertility rate of up to 80 ~ 90%, female fertilization ability is not affected. Hybrids of wheat and bridge breeds naturally pollinated with rye in the isolation area after chemical killing, yielding numerous hybrids. This not only saves manpower and time, but also makes use of some self-fertility rate retained after the killing to breed a new bridge line that wheat and rye can cross.
