甘薯的平均单产提高不大已成为降低成本的主要限制因素之一。此外,甘薯作为能源型作物也已为世人所瞩目。在这种情况下,提高生产力就显得尤为重要,而提高产量也是目前的重要研究课题。提高块根的贮存能力是提高甘薯生产力的先决条件。本文主要从生理学的侧面介绍提高 One of the major limiting factors in reducing costs is the small increase in sweet potato yields. In addition, sweet potato as an energy-based crop has also been the world’s attention. In this case, to increase productivity is particularly important, and to increase production is also an important research topic. Raising the storage capacity of roots is a prerequisite for increasing sweet potato productivity. This article introduces mainly from the side of physiology
