石榴扦插技术
石榴扦插技术,石榴用种子繁殖,要近五年才能挂果;如用扦插、压条或切取根蘖等方法繁殖,一般也要2~3年才能开花挂果。
若要石榴当年开花挂果,可利用石榴扦插易活的习性,在6月中、下旬,当新生枝条呈半木质化,枝条上并有花蕾出现时,截取带有花蕾的枝梢,随即插于盛有砻糠灰的盆中,置荫蔽处养护2星期左右,当生有少量新根时,可移至盛有砻糠灰与培养土各半的盆中,先置阴凉处放2~3天,再转到半阴处过渡3~4天,最后放在阳光处直晒。
再过10~15天,当小苗生长健壮、根也长多了,可行定植,1株1盆,盆径以10~12厘米为宜,按盆栽石榴进行养护,到时间可开花挂果了。
由于插穗原本带有花蕾,若成活后,能与一般盆栽石榴同期开花挂果。一只小小的盆中,开出几朵红花儿,结上几只红果,小巧玲珑,甚是可爱,以上就是关于石榴扦插技术的介绍。
