摘　　要：在我国仅有新疆是单叶蔷薇自然分布区，根据试验观察发现单叶蔷薇的年生长发育期可划分5个不同阶段：萌芽期、展叶期、开花期、成熟期、落叶休眠期。单叶蔷薇对生境土壤的酸碱度适应范围广，在pH值6．5～9．5范围内均可生长，并可分布至轻度盐渍化土壤，能适应极端温度，极端高温42．8℃，极端低温-39．8℃，全年降水量156．7mm情况下也能生长良好。从生物学特性和生态特性的基本规律看，单叶蔷薇属于旱生植物。单叶蔷薇花期4～6月，此期间在新疆开花小灌木植物不多，这对具有特殊气候的新疆来说很有资源价值。Only Xinjiang was Hulthemia berberifolia natural distribution area in China. According to the experimental ob- servation of Hulthemia berberifolia annual growth and development cycle can be divided into five distinct stages： bud, leaf ex- pansion, blossom period, mature period, deciduous dormancy period. Hulthemia berberifolia on habitat soil pH to adapt to a wide range, the value of pH was 6.5-9.5, and could be distributed to mild saline soil. Adapt to extreme temperatures, ex- treme high temperature 42. 8℃, extreme low temperature-- 39. 8℃, annual precipitation 156. 7mm case also could grow good. From the basic laws of biological characteristics and ecological characteristics, Hulthemia berberifolia belong to xero- phytes. Hulthemia berberifolia florescence was April to June, this time in Xinjiang blossom small shrubby plants was not much, it was resource value of special climate of Xinjiang.
