很多花木,如石榴、夹竹桃、扶桑、黄杨、女贞等,根颈部位易萌发蘖芽。一般养花者见到便把它抹掉,十分可惜。笔者繁殖花木一半用蘖芽扦插,成活率一般可达95％以上。 1.扦插基质选用河沙、珍珠岩、细炉渣(米粒大小)做基质,通透性好,不易积水烂根。 2.扦插时间和方法蘖芽萌发多在雨季,此时空气湿度大,扦插易发根成活。采芽时用刀贴根颈处切下,长5厘米以上的芽都可利用,切时带点马蹄形更好,顶尖要保留,下部叶子要去掉2/3,叶片大的要剪去一些。用筷子扎孔后,插入芽苗的1/3～1/2。随采芽,随扦插,随按实。插后浇一遍水。
A lot of flowers, such as pomegranate, oleander, hibiscus, boxwood, privet, etc., prone to germination of the root neck and tiller bud. It is a pity that ordinary flower seekers will erase it. I reproduce half with tiller bud cutting, the survival rate of up to 95%. 1. Cuttings matrix selection of sand, perlite, fine slag (grain size) as a matrix, good permeability, easy to water rotten roots. 2. Cutting time and methods Tiller bud germination in the rainy season, when the air humidity, cutting easy to root survival. Bud when the root of the neck with a knife cut off, 5 cm long buds are available, when cut a little better horseshoe shape, top to keep the lower part of the leaves to be removed 2/3, a large blade to cut some. After using the chopsticks to tie holes, insert sprout 1/3 ~ 1/2. With mining buds, with cutting, with the real. After pouring poured water again.
