木瓜海棠控花技术研究

目的]研究木瓜海棠的花期调控,探讨其促成栽培技术。方法]对木瓜海棠生长温度、湿度及光照等进行科学合理的物理控制,通过生长调节剂等化学处理,使其打破休眠,提前开放。结果]结果表明,木瓜海棠在入温室前必须在室外接受一定的低温处理才能充分打破休眠,提前开花;木瓜海棠在经过充分的低温处理下,温度达到10~25℃即能提前开花。结论]影响木瓜海棠花期调控的诸多因素中温度是关键。

Research on the Blossom-control Technique of Chaenomeles cathayensis

Objective] The research aimed to study the flowering time regulator of Chaenomeles cathayensis and investigate its forcing culture technique.Method] The growth temperature,humidity,light of C.cathayensis was controlled reasonablely in physical method,and then treated with growth regulator,to break its dormancy and flower in advance.Result] The results showed that before planted in greenhouse,C.cathayensis must be treated with low temperature in order to break dormancy and flower in advance.After been treated with low temperature sufficiently,C.cathayensis could flower in advance when the temperature was 10-25 ℃.Conclusion] Among factors influenced the regulator of C.cathayensis,temperature was the key.
