建兰

 建兰的养殖方法       

1、土壤：建兰的根系发达且粗壮，建兰对土壤的透气性要求会比较高，所以可以选用泥炭土、腐叶土、草炭土、发酵过的花生壳、发酵过的锯末屑、发酵过的原木刨花以及腐熟的树皮等。2、浇水：盆栽建兰的土壤要保持湿润，但是不可以多浇水。一定不可以根部积水。夏季要向建兰的叶片多喷点水。3、阳光：建兰是比较喜欢光照充足的花卉物种，日常养护可将其放在兰架的最上面一层容易见光的地方，尽量少遮阴，不然的话不易起花，有些建兰品种日常养护还需要曝晒才可以开花。4、温度：建兰耐寒性差，越冬温度不低于3℃，否则冻害。在20°~28°之间生长旺盛并开花结果，温湿度适宜的情况下，大部分品种一年内可开花两次，某些品种可开花四次，不耐32°以上的高温，0°以下冻伤，植株发黑死亡。                                                                                                                                                                                                                                                                                            建兰的作用

凤仙花           凤仙花的花期         凤仙花的花期在6月上、中旬就可以开花了，花期可以保持两个月以上。播种前，应对凤仙花的苗床浇透水，让它保持湿润，凤的种子是比较小的，播种后不能立刻就浇水，以免把种子冲到外面去。再盖上大约3—4毫米的一层薄土且注意遮荫，大约10天后就可以出苗了。当小苗长出2-3片叶子时就要准备移植，以后就可以逐步定植或者上盆培育。
