切花玫瑰弓型整形栽培技术

切花玫瑰弓型整形（ア－ チング）栽培是目前日本切花玫瑰的最新栽培技术，被认为是玫瑰栽培划时代的技术革新。已嫁接上品种接穗的砧木直接扦插在小块岩棉（ロツクウ－ ル）上，每块上插２根。生根成活后移放到作为栽培床的大块ロツクウ－ ル上。植株最先发出的３～４根枝作为营养枝，摘去花蕾从基部扭伤弯曲，此后从基部发出的枝作为开花枝培养，切花时留１～２ｃｍ 从开花枝基部剪截。这种方法避免了因土壤带来的不良因素；弯曲的枝条作为稳定的营养源不会因为切花而对植株造成大的伤害，既使是夏季也能正常产花；因植株较矮，温室内植株之间光照影响几乎没有，而且整形修剪等操作变得简单；可以周年产出高品质切花。

Study on the arching Culture Technique of Rose Cut flower

The arching culture technique of cut flower rose was thought to be revolution in rose cultivation.The seedling were planted in a small lump of rockwool.After rooting,the small lump of rock wool with seedling was transferred to a big lump of rockwool(or another base).Usually,there were two plants and two drop tapes in every small lump of rockwool.The shoots were bent to be come arch shape after the flower buds were removed.The standing shoots developed from the base of the plant and were cultured as flower branches.This method avoided all harmful effects from the soil.The bent branches were both the stable resources of nutrition and unharmful to the plant when cut flower.In summer the cut flower can also be obtained.There was almost no influence each other on illumination in green house and pruning was very easy because the plants were short.The cut flower with high quality could be produced all the year round.
