在杂交稻制种栽培中,提高母本结实率一直是夺取高产的关键环节。在措施上是以增加父本花粉量(如加强父本栽培、保证花期相遇等)和促进花粉传播(如喷920和割叶等)为中心;在认识上是基于充足的花粉是提高结实率的保证。这些无疑应当进一步加强。随着进一步的研究,
In the hybrid rice cultivation, raising the rate of female seed set has always been to capture the key to high yield. The measure is to increase the amount of male parent pollen (such as strengthening the paternal cultivation, to ensure that the flowering encounter, etc.) and to promote pollen transmission (such as spray 920 and cut leaves, etc.) as the center; in recognition is based on adequate pollen is to improve the seed setting rate The guarantee. These should undoubtedly be further strengthened. With further research,
