Therefore, the harvest of maize seeds to pay during the cross-breeding is the quality of the South catch one of the key links is to determine the germination rate, the main part of the net. What to do during this period, what are the key technologies in order to ensure the quality of the seeds. In this regard, talk about some opinions. 1 to ensure the rate of germination rate of the key technical measures 1.1 harvest time. Early harvest is the impact of germination rate, clarity
