| 对2011-2016年云阳引种冬枣生长发育进行观察记载，分析与评价冬枣在云阳地区栽培适应性。结果表明：云阳气候条件能够满足冬枣植株和果实的生长发育，冬季0-7.2℃低温基本满足冬枣植株自然休眠的需冷量，但夏季高温（＞35℃）会对果实生长发育造成一定的不利影响。生长期内适宜的空气相对湿度和充沛的降水量为冬枣的花期、果实生长发育提供了良好的气象条件。冬枣萌芽期提前至3月上旬，成熟期提前至9月上旬，落叶期延后至11月中旬。果实生育期110-115天，年生长周期为240-270天，休眠期缩短。结论：冬枣可以在云阳地区海拔400-800m区域引种栽培和示范推广。 |

| Abstract: The growth of jujube introduced were observed and recorded in Yunyang region from 2011 to 2016 year, and it’s ecological adaptability was evaluated. The results showed that the climate conditions in Yunyang region was good for the plant and fruit growth of jujube, and 0-7.2 low temperature basically met the chilling requirement of jujube plant dormancy in winter, but high temperature (＞35 C) in summer would cause certain adverse effects on fruit growth and development. The suitable air relative humidity and abundant precipitation during the growth period of jujube were good climatic conditions for flowering and fruit growth. Germination period of Jujube advanced to early March, and fruit maturity was the early September, and defoliation postponed to mid November; The fruit growth period was about 110-115 days, Annual growth cycle was about 240-270 days, and the dormancy shortened. Conclusion: jujube could be introduced, cultivated and demonstrated at the altitude of 400-800m in Yunyang region. |
