高山杜鹃施肥正交试验及温室栽培管理

Orthogonal Test of Fertilizer and Cultivation Management of Rhododenndron hybridum in Greenhouses

【目的】确定栽培高山杜鹃科学的施肥方法及掌握其温室栽培管理的关键技术。【方法】利用正交设计法研究不同施肥处理对高山杜鹃叶片叶绿素含量的影响。【结果】高山杜鹃叶绿素含量最佳的施肥方式是施肥浓度为500 mg/L,每15 d施肥一次,采用喷灌方式,高山杜鹃叶绿素含量达到161.39 mg/100 g,掌握其温室栽培管理的关键技术。【结论】高山杜鹃叶面施肥效果好,其温室栽培重点控制好水质和光照。

[ Objective] The purpose of this project was to confirm the scientific method of fertilization on Rhododendron hybridum and to grasp the key techniques of cultivation of it in greenhouses. [ Method ] The orthogonal design was used to study the effects of different fertilization on leaves chlorophyll content of Rhododendron hybridum. [ Result] The results showed that the largest concentration of fertilizer for chlorophyll of Rhododendron hybridum is 500 mg/L, and fertilizer could be used every 15 days. Spray irrigation method could make the chlorophyll content of Rhododendrons hybridum reach 161.39 mg/100 g. This was the key technique of cultivation to be grasped in greenhouses. [ Conclusion ] Fertilizing leaves had good effect, and controlling water and light was the key for Rhododenndron hybridum in greenhouses.
