低温敏两系核不育系春繁主要是通过冷水串灌技术。冷水串灌繁殖时需要把冷水从田块的一边灌进,从另一边排出,通过低温水的流动,使田间水温保持在不育系不育起点温度以下和生理不育下限温度以上的范围之内。为了解决低温敏两系核不育系在黄山繁殖中存在的问题,通过分期播种,冷水串灌技术,探讨不育系在黄山地区的春繁技术措施,为今后两系不育系在黄山春繁提供经验总结。 Low temperature-sensitive two-line nuclear spring sterile mainly through the cold water string irrigation technology. Chilled water when breeding need to pour cold water from one side of the plots, discharged from the other side, through the flow of low-temperature water, the field water temperature to maintain the sterile line below the starting point of infertility and the lower limit of the range of physiological infertility Inside. In order to solve the problem of low temperature sensitive two-line CMS in Huangshan breeding, this paper discussed the technical measures of spring propagation of sterile line in Huangshan by staging sowing and cold water string irrigation technology, Experience summary.
