通过Ｒｉｃｈａｒｄｓ方程模拟，探讨了双增剂对籽粒胚乳细胞增殖及粒重变化的影响。结果表明，双增剂能通过提高胚乳细胞平均增殖速率来提高最终胚乳细胞数；通过提高籽粒平均灌浆速率和延长粒重活跃增长期来提高最终粒重，并且双增剂对粒重的效应表现为低肥处理大于高肥处理。
The Richards equation was used to simulate the effect of double-agent on the proliferation and grain weight of endosperm. The results showed that the dual augmenting agent could increase the final endosperm cell number by increasing the average proliferation rate of endosperm cells; increasing the final grain weight by increasing the average filling rate of grain and prolonging the active period of grain weight, and the effect of double increasing agent on grain weight For low fat treatment than high fat treatment.
