桃是我国重要水果之一。尤其早熟品种,在水果淡季上市,对活跃市场,增加果农收益,有着重要意义。所以长期以来,早熟桃的育种和栽培,都为国内外所关注,竞争也十分激烈。就兰州而言,以往最早熟的“六月桃”在七月底上市。大部分桃集中在八、九月供应,形成“早熟缺、晚熟劣、中熟集中”的品种分布格局。前几年从北京引进一些早熟桃(如麦香、京红等),上市期提早到七月上、中旬,发展很快,有些果农由此而致富。但七月以前,仍无本地桃供应,外来桃经长途转运,损失严重,价格昂贵,每斤高达一元以上。
Peach is one of the important fruits in our country. In particular, precocious varieties, listed in the off-season fruit, the active market, increase the income of farmers, of great significance. Therefore, for a long time, the breeding and cultivation of early-maturing peach are both concerned at home and abroad, and the competition is fierce. For Lanzhou, the earliest known “June Peach” went public at the end of July. Most peaches concentrated in August and September supply, the formation of “precocious, late-maturing, concentrated in the middle” of the species distribution pattern. A few years ago from Beijing to introduce some early peach (such as wheat, Beijing Hong, etc.), the listing period early in July, mid-fast development, some fruit farmers thus become rich. However, before July, there was still no local peach supply. Exotics were transhipped via long distance transport. The loss was serious and the price was so high that they were as high as one yuan per catty.
