盆栽花卉倒盆方法
倒盆有三种情况:
一种情况是盆花经过一段时期的生长,株幅增大,造成株间拥挤,为了加大盆间距离,使之通风透光良好,植株生长健壮,并防止病虫危害和徒长,必须及时进行倒盆。另一种情况是在日光温室中,由于盆花放置的部位不同,光照、温度和通风等环境因子的影响也不同,盆花生长情况各异。为了使花卉产品生长均匀一致,要经常进行倒盆,将生长旺盛的植株移到条件较差的部位,而将较差部位的盆花移到条件较好的部位,以调整其生长。
第三种情况是在一栋温室里同时栽培有二种以上盆花时。为了获得生长发育良好的植株,就要考虑在温室里如何放置的问题。放置不当,不仅影响花卉的生长发育,而且对温室的利用亦极不经济。根据日光温室的性能和植物的生态习性,通常把喜光的花卉放在光线充足的温室前部和中部;
耐阴的和对光线要求不严格的花卉放在温室的后部或半阴处。把矮的花卉放在前面,高的放在后面。把喜温花卉放在近热源处,把较耐寒的强健花卉放在近门及近侧窗部位。休眠的植株对光线、温度要求不严格,可放在光照、温度条件较差处,密度可以加大;植株发芽后,移到有适宜光照的部位;随着植株生长,株幅不断扩大,应给予较大的空间。
