Embodiment Construction
[0040] Specific embodiments of the present invention will be described in detail below.
[0041] A millet hybrid seed production method for coordinating the flowering period and preserving seedlings in the field, specifically as follows:
[0042] Ⅰ. Planting and seed production: hybrid millet farming is used to cultivate seedlings according to the different staggered dates, different proportions and suitable time of the parents.
[0043] According to every 667m 2 (mu, the same below) The seedling field area is set at 10~20m 2 , where the seedling field area is divided into the female parent seedling field and the male parent seedling field, for example: Zhang Zagu No. 5, the female parent is: A 2 , the male parent is: Improved No. 21, the ratio of the area of the female parent's seedling field to the male parent's seedling field is 4:1, that is, the area of the female parent's seedling field is 8-16m2 per mu 2 , male seedling field area 2~4m 2 .
[0044] The seedling ...
