金花茶1年多次抽梢栽培技术研究

Research on Cultivation Technique for Multiple Sprouting of Camellia petelotii in One Year

为获取高品质金花茶(Camellia petelotii)叶,以自研有机菌肥、普通有机肥和化肥为研究对象,探究不同施肥处理对金花茶抽梢率及植株和叶片生长的影响。结果表明,3—4月,自研有机菌肥与普通有机肥+追施化肥处理均可有效促进金花茶抽梢,使金花茶1年抽梢2次;2种处理的金花茶树高和冠幅均极显著高于其他处理。自研有机菌肥处理的金花茶叶长、叶宽、叶面积、叶片厚度和鲜叶重均显著高于其他处理,说明自研有机菌肥可提高金花茶叶产量和质量。

In order to obtain high quality leaves of Camellia petelotii,effects of different fertilization treatments on sprouting rate and growths of plants and leaves of C.petelotii were investigated by using self-developed organic bacterial fertilizer,normal organic fertilizer and chemical fertilizer.Results showed that treatment of selfdeveloped organic bacterial fertilizer and normal organic fertilizer+topdressing could promote sprouting of C.petelotii and make C.petelotii sprout twice a year.Plant heights and crown widths of C.petelotii in two treatments were extremely significantly higher than those of other treatments.Leaf length,leaf width,leaf area,leaf thickness and leaf fresh weight of C.petelotii using self-developed organic bacterial fertilizer were higher than those of other treatments,which indicated that self-developed organic bacterial fertilizer could improve yield and quality of C.petelotii leaves.
