现有的水稻杂交技术有多种。国内目前采用较多的是温汤杀雄法,在开花当日上午杀雄授粉。其缺点是工作时间短,田间工作环境差。IRRI采用剪颖真空去雄法,是在开花前一天剪颖,同时真空去雄,次日授粉。此法延长了工作时间,但速度仍有限,同时国内缺乏设备,使用尚不多。1981年江西宜春地区农科所试验了剪颖温汤去雄法, There are many existing hybrid rice technologies. At present, more commonly used is Wen Tang Kill male law, to kill male pollination in the morning on the flowering day. The disadvantage is the short working hours, poor working environment in the field. IRRI shears Ying-sheng vacuum method is cut the day before flowering Ying Ying, while the vacuum to male, the next pollination. This law extended working hours, but the speed is still limited, while the domestic lack of equipment, use is not much. In 1981, Jiangxi Yichun Agricultural Science Institute tested the shear Yingwen Tang to the male method,
