扦条准备。三角梅为难生根繁殖以扦插为主的花灌木。插条选1—2年生,完全木质化,条粗0.8—1.2厘米,条长12—15厘米,节间密,有侧芽4—5个的枝条。上剪口距芽眼0.5—1厘米处于剪,下剪口贴近芽眼处斜剪为马蹄形,不可在芽中段下剪,无芽眼处一般不生根。剪时摘除基部叶片,只带顶芽1—2片幼叶。插条按50—100枝为一捆,先浸入清水中,然后用ABT生根粉1号50ppm,浸条2—4小时,备用。插壤。用河砂作生根基质,河砂用20‰高锰酸钾水溶液消毒后装入塑料钵中使用,塑料钵底部应用1—3个排水孔。扦插时间。春天3—月,秋天8—9月为扦插育苗最佳时间。其余月份生根率偏低不宜大量育苗。温度。三角梅原产南美巴西,为亚热带强阳性植
Cuttings preparation. Bougainvillea Difficult rooting propagation to cuttings based flower shrubs. Cuttings selected 1-2 years, completely lignified, thick strips 0.8-1.2 cm, length 12-15 cm, internode dense, with 4-5 branches shoots. 0.5-1 cm from the eye on the cut eye cut in the mouth, under the cut close to the bud Eye oblique cut horseshoe-shaped, not cut in the middle of the bud, no eye generally do not root. Excision of the base cut leaves, with only 1-2 buds young leaves. Cuttings by 50-100 as a bundle, first immersed in water, and then ABT rooting powder No. 1 50ppm, dipping 2-4 hours, spare. Loose soil. River sand as rooting substrate, river sand with 20 ‰ of potassium permanganate aqueous solution after disinfection plastic bowls used in the application of plastic bowls 1-3 drainage holes at the bottom. Cutting time. Spring March-August, August-September autumn is the best time for cutting propagation. The rest of the month rooting rate is not suitable for large numbers of seedlings. temperature.
