摘　　要：在设施大棚内应用夜间补光、增温、营养等措施,诱导4个品种红肉火龙果Hylocereus polyrhizus植株抽生三个批次冬春花,观测其花果生长期状况,分析红肉火龙果花果生长期与温度的关系。结果表明,温度显著影响火龙果冬春花果生长期,两者之间极显著负相关。三个批次红肉火龙果花果生长期差异明显,棚内温度越高,花果生长期越短。冬春季花生长与果生长的最低临界温度差异较大,分别为9℃和15℃。The relationship of temperature and growing period of Hylocereus polyrhizus flower and fruit was studied under the condition of shed in winter and spring.The growth and development of red flesh pitaya flower and fruit was regulated by applying supplement light,increasing temperature and nutrition in the study.Four cultivars of red flesh pitaya were induced three batches winter-spring flowers.The growth conditions of red flesh pitaya flower and fruit during growing period were observed.The results showed that the flower and fruit growing period of red pitaya was affected significantly by temperature,and there was a significantly negative correlation between growing period and temperature.The results also showed that the red flesh pitaya growing periods of three batches were obvious difference.The growing period of flower and fruit was shortest while the temperature was highest in the shed.The minimum critical temperature was great different between flower-bud growth and fruit growth,which were 9℃ and 15℃ respectively.
