北京奥运月季花期调控

月季花期调控和增加花量的研究是通过采用不同修剪强度、修剪时间、施肥水平等方式使北京城市栽培的月季于奥运会期间持续开花,同时增加花量。试验结果表明:修剪强度对月季花期调控和增加花量具有较大的效应,采用强修剪、中度修剪和弱修剪相结合的修剪方式有利于调控花期;修剪时间受气温、开花周期和修剪强度等多因素影响;施肥数量和施肥种类影响月季开花的质量、数量和抗逆性。温度是藤本月季花期调控的最大影响因子,不同品种受温度影响的程度存在差异。

Florescence Control of Roses During Beijing Olympic Games

The florescence control and the flowers increasing trial of roses was used the prune degree,the prune time and the fertilizer for the flowers in full bloom during the Beijing Olympiad Game.The results showed that the prune degree was of the upright effects in the florescence control and flowers increasing,which were integrated with the mass prune,middling prune and bit prune.The prune time was influenced by atmospheric temperature,the abloom periods and the prune degree.The bloom characters,the flower numbe...
