(一)引言有关我国栽培植物起源,常常引起许多人的关心和兴趣,这是很自然的。因为它与一个国家农业起源和文化发展总是联系在一起的。我们在研究栽培植物起源时,除需要探讨有关古文献和考古学等方面的问题外,对于栽培植物野生种或者与它们有亲缘关系的野生植物分布的了解和标本种子的采集,是不可缺少的一个重要环节。特别是青藏高原,在那里酝藏着极为丰富的生物资源,其中植物资源不仅对国家经济建设和遗传选种提供重要材料,而且对论证我国是世界栽培值物起源的主要中心之一具有重要意义。在我国黄河、长江中下游的广大农区已经难以看到栽培植物野生种,而它们都有希望在青
(A) Introduction It is natural that the origin of cultivated plants in our country often draws many people’s interest and interest. Because it is always associated with a country’s agricultural origins and cultural development. In studying the origin of cultivated plants, apart from the need to explore issues related to ancient literature and archeology, it is indispensable to understand the distribution of wild plants of cultivated plants or their related wild plants and to collect samples of seeds An important part. Especially the Qinghai-Tibet Plateau, where extremely rich biological resources are brewed. Plant resources not only provide important materials for national economic construction and genetic selection, but also have important significance for demonstrating that our country is one of the major centers of origin of cultivated value in the world . In China’s Yellow River, the vast agricultural areas in the middle and lower reaches of the Yangtze River have been difficult to see the cultivation of plant wild species, and they have hope in the green
