| 摘 要： | 目的]定期调查红枣根系生长状况,同时结合对地上部枝、花、果实的调查,探讨地上部与根系生长相关性,以期为建立环塔里木盆地红枣栽培高效模式,协调红枣根、冠结构,为肥、水调控提供理论依据.方法]在环塔里木盆地干旱区中心地带阿克苏,以8年生灰枣为试材,利用根窖法研究栽培条件下其根系与地上部生长之间的相关性.结果]5月20日,玻璃观察界面上开始出现新根.7月5～31日是发根高峰期,发根量约占整个发根总量的3/5,此后新生根数量明显减少,此时地下20cm土壤温度为20.8℃.结论]根系与地上部分生长呈交替现象,且与开花和果实生长存在一定的竞争.

| Abstract: | 【Objective】The present study was set to investigate the roots growing condition of jujube,and observe the aboveground branches,flowers and fruits,discuss the relationship between root growth and aboveground growth,in order to provide theoretical basis for construction of culture high-efficient mode of jujube in Tarim Basin.【Method】The study aimed at the correlation between root system and aboveground growth by use of grey jujube grown for 8 years in the central zone of Tarim Basin as test materials.【Result】On May 20th,the white new roots started grow.A large number of new roots took place on July 5th to 31st,the period of rooting volume as a whole accounted for about rooting total of 3 / 5.The roots mainly focus on 15-50 cm depth underground and the new roots in different soil layers grew alternatively.【Conclusion】New roots and aboveground growth replaced aternatively,the competition growth bewteen root,blooming and fruit growth occurred. |
