摘要
研究结果表明,水稻旱作条件下灌浆速率为单峰曲线,以强势粒灌浆为主;水作条件下灌浆速率为双峰曲线,强势粒和弱势粒灌浆并重,旱作条件下结实率较低是由于缺乏弱势粒的灌浆,所以应取相应的提高弱势粒灌浆速率的栽培措施来提高结实率。
The experimental results indicated that the grain filling rate fit a single peak curve and the strong tendency grain played an important role in yield under dry cultivation. Under aquatic cultivation the grain filling rate fit a double peak curve and the strong tendency grain and the weak tendency grain both played important roles in yield. The reason of lower filling rate was lack of filling of the weak tendency grain, and therefore we should take some corresponding culture measures to enhance the weak tendency grain filling and the filling spikelet rate.
