南方酸性土花木如茶花、杜鹃、米兰、桅子等,在北方繁殖比较困难。经试验,采用药物处理和改变基质的方法效果较好。其要点如下: 基质 基质最好采用蛭石。因其色暗吸热多,疏松透气无杂菌,插条生很后上盆不易受损。要求基质厚15至20厘米,插前用5％高锰酸钾约液消毒,2至3天后再行扦插。 插条 插条须选当年生粗壮枝,长10至15厘米。枝上留3至4片叶,每叶剪去一半。插重切口要上平下斜,这样产生的愈合组织大,生根多。
Southern acidic soil and flowers such as Camellia, Rhododendron, Milan, gardenia, breeding in the north is more difficult. After testing, the use of drug treatment and change the matrix method is better. The main points are as follows: Matrix substrate is best to use vermiculite. Because of its color, dark heat, loose and breathable without bacteria, cuttings on the basin is not easy to damage. Requires matrix thickness of 15 to 20 cm, before plugging with 5% potassium permanganate solution disinfection, 2 to 3 days after the cuttings. Cuttings should be selected when robust stalks, length 10 to 15 cm. Leave 3 to 4 leaves on the branch, cut in half by each leaf. Heavy cut incision to ramp down, resulting in healing tissue, rooting and more.
