‘上海之春’是上海市周圣希同志于1978年培育成功的月季新品种。花为浓艳的红橙色,50枚左右的花瓣,构成了平头满心而又带翘角状的整齐优美的花型,且颜色保持性好,耐开,在橙色系列月季中有其独到的优点。美中不足的是枝条不够挺拔,稍显笨拙。尤其是盆栽,不易形成匀称的棵型。如何克服这一不足呢?可抓住以下几个环节: 1.一定要用扦插苗(或高压苗):嫁接苗抽发新枝在土面以上嫁接点处,从土面到嫁接点的距离增加了植株高度,不易修剪成矮壮的棵型。而扦插苗能从土面以下不断萌发土生枝,这是修剪成型的基础,是植株不断更新的条件。 ’Spring of Shanghai’ is a new variety of rose cultivated successfully by Comrade Zhou Shengxi in Shanghai in 1978. The flowers are richly colored red-orange, with about 50 petals, forming a smooth and graceful flower pattern with a flat head and a curled corner. The color is well maintained and resistant to opening. Its orange-colored rose has its unique advantages. Fly in the ointment is the branches are not tall enough, slightly clumsy. In particular, potted plants, not easy to form a symmetrical tree type. How to overcome this deficiency? Can seize the following links: 1. Must use cutting seedlings (or high pressure seedlings): grafting seedlings new branches in the soil grafting above the grafting point, the distance from the soil to the grafting point increased The plant height, not easy to trim into a sturdy tree. The cutting seedlings from the soil surface below the continuous germination of native branches, which is the basis of pruning, is constantly updated plant conditions.
