龟背竹的无土栽培方法
龟背竹的无土栽培方法,无土栽培龟背竹可用蛭石与珍珠岩按1:1的比例混合代替土壤栽植,渗水、保水能力都比土壤好。
在进行换盆时,将用土壤栽植的龟背竹从原盆脱出,置清水中轻洗,由于龟背竹须根较粗,不会因搓洗而断裂,要洗净根上残留泥土。若植株较大,可在盆面上盖一层约3厘米厚的碎石,以防植株倒伏。四季均可换盆,即使在生长季节也无妨。
换盆后,第1次浇液要浇足,使盆底托盘有渗出液为止。要使植株生长旺盛健壮,要浇灌1%的硫酸铵肥液,一般在换盆后10天浇1次;在生长旺季的5~7月间,要每周浇1次;春、秋两季,可半月浇1次;冬季则1个月浇1次。在基质稍干时浇灌,浇至盆内基质全部湿润为止。
在生长季节,每隔数天,用蘸有含氮液肥的湿布擦拭叶片,这样既能使叶片碧绿苍翠,还能起到根外追肥的作用,使龟背竹生.长更为健壮。龟背竹长大后,常呈匍匐状,需要立支架绑缚,以上就是关于龟背竹的无土栽培方法的介绍。
