米兰花怎么繁殖
米兰花怎么繁殖,米兰花的繁殖主要有扦插和高空压条等方法。
1、扦插繁殖
一般在6~8月份进行。插穗要选择当年生木质化的枝条,长10~15厘米,剪去下部叶子,仅在先端保留2~3片叶子。用利刀将插穗长度的1/2上面覆盖玻璃或塑料薄膜。要保持一定的温度和湿度,大约经过两个月后即可生根。如果用奈乙酸或吲哚丁酸水溶液浸蘸插穗,可以加速生根,提高成活率。
2、高空压条繁殖
选择一年生已木质化的健壮枝条,在距离茎部10~15厘米处进行环状剥皮,剥皮要深达木质部,宽度在2~3厘米。用酸性腐植土包敷在剥皮部位,再用塑料布包紧,经常浇水,保持湿润,约经3个月伤口部位即可生根,此时可以从母株上切取,栽于盆内。此法安全可靠,并可获得粗大植株。时间一般选择7、8月份,因为此时空气的温度、湿度都比较大,有利于保湿、生根。高空压条除环剥外,也可将枝条由下向上斜切一刀,劈开切口,将小石子等物夹在枝条劈开处,同时在伤口处涂上汁液B12,再敷上青苔或蛭石,然后用塑料布扎紧,经常保持湿润,待生根后从母株上剪下,就成为一株新的米兰,以上就是关于米兰花怎么繁殖的介绍。
