夹竹桃植株比较高大,在南方地栽可达5～6米,在北方盆栽也可达3～4米,这样高的植株在楼房阳台上难以摆放。为此,笔者对其进行了矮化处理,经过10年的实践,效果很好,而且能促进提前开花。现将方法介绍于下: 1.水插育苗 3月初,从母株上剪取1～2年生成熟枝条,长15厘米左右,下部在节处用小刀劈开1厘米小缝,用200ppm生长素水溶液浸泡一昼夜,然后插入玻璃罐头瓶内,盛水3～4厘米,放于温暖处。保持水温20～25℃,
Oleander plants relatively tall, planted in the south up to 5 to 6 meters, up to 3 to 4 meters in the northern potted plants, so tall plants in the balcony of the building is difficult to display. To this end, the author dwarfed it, after 10 years of practice, the effect is very good, but also to promote early flowering. The method is introduced in the following: 1. Water inoculation nursery early March, from the parent plant cut 1 to 2 years to generate mature branches about 15 cm long, the lower part of the knives with a small split 1 cm slit with 200ppm auxin Aqueous solution soak for a whole day and night, and then insert the glass cans bottle, water 3 to 4 cm, placed in a warm place. Keep the water temperature 20 ~ 25 ℃,
