供兰香的繁殖方法目前国内外均采用有性繁殖,但它有许多弊病,如周期长,变异性大,单株产花量不等,开花迟早不一,而且植株向高生长,不利于采花和抗风,因此对生产推广极为不利。据我所320株七年生依兰香实生树的调查,其株高达7米以上,开花株为120株,占调查株的37%。就开花树而言,每树年产花量也不等,高的可达2公斤以上,低的仅开数十朵花。 There are many disadvantages, such as long cycle, large variability, different flower yield per plant, the sooner or later flowering, and the growth of plant to high, which is unfavorable to Flowers and wind, so the promotion of production is extremely unfavorable. According to my survey of 320 seven-year-old Ylang-Ylang-Hong tree, the height of the plant was more than 7 meters and that of flowering plants was 120, accounting for 37% of the surveyed strains. In terms of flowering trees, the annual yield of each tree is not the same, high up to 2 kg or more, low dozens of flowers only open.
