许多国家正在研究获得马铃薯原始材料的技术,以保证在最合理的资金开支情况下,提高杂交种子生产率,增加单个块茎的产量以及提高块茎质量。这方面工作的成就,取决于对影响其栽培的因素的研究,如光周期、获得杂种实生苗的条件发、农业技术,水分保障率、营养水平和生长剂的加工制造等。国外进行的研究表明,为取得整齐的幼苗,从浆果中分离杂交种子的技术十分重要。在美国,把收集的浆果放在温室的专用容器里贮藏3～5周,使其软化成熟。以后把浆果打 Many countries are studying techniques for obtaining raw potato material to ensure increased hybrid seed productivity, increased individual tuber yield, and improved tuber quality at the most reasonable cost of capital. Achievements in this field depend on studies of the factors that affect their cultivation, such as the photoperiod, the conditions under which hybrid seedlings are obtained, agricultural techniques, moisture protection, nutritional levels, and the processing and manufacturing of growth agents. Research conducted abroad shows that it is important to isolate hybrid seeds from berries in order to obtain tidy seedlings. In the United States, the collected berries are stored in a dedicated container in the greenhouse for 3-5 weeks to soften and mature. After the berries hit
