目前各地采用的水稻杂交方法,还存在一些问题,如用杀雄器或保温瓶等杀雄,杀雄效率不高,且易损伤植株;剪颖去雄常去雄不彻底和种子质量较差;田间去雄还受气候干扰,容易发生异花串粉,操作也不便,使杂交工作感到困难。为了适应当前育种工作迅速发展的要求,针对这些问题,作了以下一些改进: 一、稻株移入室内:我们从1966年开始采用稻株移入室内进行,沿用至今,感到此法操作方便简易,效果良好。具体作法是:在计划杂交的当日上午,至迟在水稻开花前1—2小时,从田间连根带泥掘起母本稻株,用长宽约1尺多的方形塑料薄膜,将带泥秧蔸包严,
At present, the methods of hybridization in rice all over the country still have some problems, such as killing the male by using the killing device or the thermos flask, killing the male is inefficient and easy to damage the plant; the clipping is not complete and the seed quality is poor ; Field to male also affected by climate interference, prone to cross-stringing powder, the operation is also inconvenient, so that cross-work difficult. In order to meet the current rapid development of breeding requirements, in response to these problems, made the following improvements: First, the rice plants moved into the room: We started from 1966 rice plants moved into the room, still in use, feel this method is easy and convenient operation, the effect good. The specific practice is: in the morning of the planned hybridization, 1-2 hours before the flowering of rice at least, digging from the field with root mud muddy paddy plant, with a length of about 1 foot square plastic film, the mud Yang seedlings strict package,
