甜荣良种的繁殖,包括母根培育、母根窖藏和采种,这是三个不可分割的部分,而其中母根贮藏量大,管理较复杂,是决定工作成败的重要一环。往往由于管理不善,将会造成巨大的损失,如内蒙古1954—1955年度母根损失率高达79.7%,但管理得好其损失率仅为千分之几,这就说明了母根贮藏在甜荣 Breeding of Sweet Seed, including breeding of parent root, cellar of mother root and seed collection, are three inseparable parts. Among them, the large amount of mother root stock and the complicated management are an important part of determining the success or failure of a job. Often due to poor management, will result in huge losses, such as Inner Mongolia 1954-1955 years, the root loss rate as high as 79.7%, but well managed its loss rate of only a few thousandths, indicating that the mother of the roots stored in sweet
