一、选株整穗。无论采用何种去雄方法,正确地选株整穗是重要的基础。人工去雄每穗留30～50小穗,温水去雄可多留一些。所留小穗最好是能在出穗后第二天开花的,至少是第三天开花的。选株、整穗要选符合育种要求、穗顶部刚开花的健壮株。整穗时把刚开过花的小穗剪去,把紧靠开过花的1～3个长的饱满的小穗留下,其余 First, the selected strains whole body. Regardless of the method used to remove male, the correct selection of whole ears is an important foundation. Artificial to male stay 30 to 50 spikelets per spike, warm water to male may stay some. The remaining spikelets are best able to flower the next day after heading, at least on the third day of flowering. Select strains, the entire election to meet the breeding requirements of the whole ear, spike just the top flowering robust strains. The entire spikelet cut off the newly spikelets of flowers, leaving 1 to 3 long full spikelets close to the flowers, leaving the rest
