培育观赏花木是农民脱贫致富的一条重要途经,而春季则是绝大部分花木进行扦插繁殖的最佳季节。春插育苗的优点在于:一是观赏植物在春季萌动后,分生组织细胞加速分裂,有利于插穗的愈合生根;二是春天雨水较多,空气湿度大,温度适中,对插穗切口的愈合和根系的分化尤为适宜;三是春插穗条生根后小苗有一段较长的生长时间,当年即可培育出符合一定规格的苗木。适于春季扦插繁殖的花木有二大类:一类是生根时间长、不易生根的灌木和常绿树,如雪松、龙柏、真柏、圆柏等类;另一类是易生根的花木,如石榴、月 Cultivation of ornamental flowers and trees is an important way for peasants to get rid of poverty and prosperity, while spring is the best season for the majority of flowers and trees for cutting propagation. The advantages of spring planting seedlings are: First, ornamental plants germinated in spring, the meristem cells accelerated division, is conducive to cutting heal the rooting; second spring more rain, air humidity, moderate temperature, the cutting incision heal and Root differentiation is particularly appropriate; Third, after the cuttings of spring cuttings have a longer period of growth time, that year can be nurtured to meet certain specifications of seedlings. Suitable for spring cutting propagation of flowers have two categories: one is rooting for a long time, not easy to root shrubs and evergreen trees, such as cedar, cypress, true cypress, Sabina, etc .; the other is easy to root the flowers , Such as pomegranate, month
