掌握作物籽粒灌浆规律有助于确定播期和追肥灌水时期,充分利用光热水气候资源,增加籽实产量。关于向日葵瘦果灌浆规律的研究已有报导。描述向日葵瘦果灌浆规律目前可供使用的模型是罗吉斯蒂(Logistic)方程,即“S”曲线。然而,我们在工作中却发现了它的不足之处。本文试图在此基础上对向日葵瘦果灌浆模型进行初步探讨。
Grasping the law of crop grain filling helps to determine the sowing date and top dressing and irrigation period, making full use of the hot and cold water climate resources and increasing seed yield. Research on the law of sunflower achenes grouting has been reported. Describing the law of sunflower achenes Grouting Currently available models are the Logistic equation, the “S” curve. However, we found its shortcomings in our work. Based on this, this paper attempts to preliminary study the sunflower achenes grouting model.
