盆栽一串红花期和株型控制研究

目的]确定一串红适宜的生产方案,为其优质生产栽培奠定基础。方法]先露地栽培一串红,之后改为盆栽养护,化学药剂控制其株型,摘心控制其花期,使一串红的栽培管理更加简便。结果]5月下旬~6月上旬开始繁殖一串红,7月上、中旬定植,9月中旬盆栽养护。若要一串红在国庆节开花,最终摘心日期在8月15日前后,同时叶面喷施多效唑。多效唑浓度为7501、000 mg/L时,一串红的株高分别为34.73、5.2 cm,冠径分别为46.34、5.6 cm,均为最佳观赏株型。叶面喷施多效唑可抑制一串红的高生长和横向生长,浓度越高其抑制作用越大。结论]采用露地栽培和盆栽相结合的方式栽培一串红,提高了一串红的观赏性和商品价值。

Study on Control Technology of Florescence and Plant Type for Pot Salvia splendens

Objective] The aim was to determine proper production scheme for Salvia splendens,and lay a foundation for its high quality production and cultivation.Method] The S.splenden was planted in open field first,and then was changed to pot maintenance,the plant type was controlled by chemical agent and its florescence controlled by pinching,so as to make cultured management of S.splenden easier and simpler.Result] S.splenden was begun to propagate from late May to early June,field planting in early and middle July,and pot maintenance in middle Sep.If the S.splenden should be flowering on National Day,the final pinching date was the pre-and post Aug.15,and foliage sprayed with paclobutrazol(pp333) as well.When the concn.of pp333 was 750,1 000 mg/L,the plant height of S.splenden were 34.7 and 35.2 cm resp.and crown diameter of 46.3 and 45.6 cm resp.,all were the best ornamental plant type.The pp333 for foliage spray could inhibit height growth and crossgrowth of S.splenden,the concn.was higher and the inhibition larger.Conclusion] The enjoyment and commodity value of S.splenden were enhanced by the pattern of combination of open and pot culture for S.splenden.
