为美化环境,培育良种,加快名贵花木的繁殖,几年来,我们在室内进行了桂花、樱花、杜鹃等多种花木、果树的扦插繁殖,成苗率达95-100%。裁植后,生长快,分枝多,开花早,结果多。现将这种扦插繁殖技术简介如下:1.插箱与基质插箱用木板做成,长60厘米,宽40厘米,高40厘米,也可用基他容哭代替,但以木质为好,以便于移动。基质采用新鲜锯末40%,腐殖质土20%,河沙20%,家禽粪10%,磷肥2%,硫酸亚铁0.5%,浇适当的淘米水,经均匀混合腐熟后平铺在箱内,厚30厘米,压实。2.采穗与催芽室内扦插一年四季均可进行,但以秋末春初为好。采穗(条)应有粗壮无病虫害幼龄树上采集,选用当年生半木质化嫩枝,剪成长12-15厘米,每穗带芽3-4个(桂花、茶花、茶梅,两叶一顶芽)。在穗(条)基部,用单面刀片,向上纵切一刀,深1.5-2厘米,浸泡在500ppm葵乙酸溶液中,3-8秒钟,竖立和在装有锯末的愈合池中,上盖双层薄膜和草苫,湿度保持在60%,温度保持在27℃±2℃,催芽15-30天。
In order to beautify the environment, cultivate good varieties and speed up the breeding of valuable flowers and trees, we have conducted various types of flowers such as sweet-scented osmanthus, cherry, rhododendrons, and other flowers and trees in the interior. Propagation of fruit trees takes 95-100% of the seedlings. After cutting, fast growth, more branches, early flowering, the results and more. Now cuttage propagation technology is described as follows: 1. The box and matrix plug box made of wood, 60 cm long, 40 cm wide and 40 cm high, but also can be used to replace him, but the wood is better, so that To move. The substrate is made of fresh sawdust 40%, humus soil 20%, river sand 20%, poultry manure 10%, phosphate fertilizer 2%, ferrous sulfate 0.5%, pour appropriate Taomi Shui, Thick 30 cm, compacted. Cuttings and germination indoor cuttings can be carried out throughout the year, but in late autumn and spring as well. Spike (bar) should be sturdy disease-free pest collection of young trees, the selection of the current half-lignified shrubs, cut 12-15 cm long, 3-4 per spike buds (osmanthus, camellia, tea plum, A bud). Spike (bar) base, with a single blade, longitudinal slitting a knife, 1.5-2 cm deep, soaked in 500ppm Kwai solution, 3-8 seconds, erected and in the sawdust healing pond, cover Double-layered film and straw, humidity maintained at 60%, the temperature maintained at 27 ℃ ± 2 ℃, sprouting 15-30 days.
