采取一圃制(原种圃)的方法繁育谷子良种,同样能起到过去采用二圃、三圃制的选优提纯效果,而其方法简单易行、功效高、效果好。据试验证明,谷子品种不需要使用二圃、三圃等复杂过程生产原种,也不必提倡年年种原种,一圃生产的原种可连续种2—3代,实行原种三年一更新,则可得到保持其优良种性,充分发挥其增产潜力。 Adopting a nursery (original nursery garden) method to breed advanced varieties of millet can also play the same excellent purification effect as that adopted by the two nurseries and three nurseries in the past. The method has the advantages of simple and easy operation, high efficacy and good effect. According to the experiment proved that the millet varieties do not need to use two nursery, three nursery and other complex process of production of original species, also do not have to promote annual seed species, a nursery stock species can be continuous 2-3 generations, the implementation of the original species three years Update, you can get to maintain its superior species, give full play to its potential yield.
