Therefore, in production practice, production levels and should be different cultivation conditions, the growing of different high yield, the stability of the species, in order to exert its potential yield. .
Therefore, in the production practice, according to different production leveland and cultivation conditions, choose to plant different varieties of productivity, stability, in order to play its potential to increase production.
Therefore, in production practice, we should choose varieties with different high yield and stability according to different production levels and cultivation conditions, so as to give full play to their potential of increasing production..
