6-Benzylaminopurine (6-BA) is a synthetic cytokinin inosimudzira kupatsanurwa kwesero, induces kupatsanurwa kwebud, uye kunonoka senescence, zvichiita kuti ive yakakodzera kukwidziridzwa kwebud mukuumbwa kwemaruva.
Kushandiswa: 6-BA inowanzoshandiswa mune soluble powder form. Inofanira kutanga yakanyungudutswa mudiki diki dilute acid (yakadai se 0.1 mol/L hydrochloric acid), yobva yanyungudutswa nemvura kune yaidiwa. Nekusimudzira kukura kwemaruva mumaruva, iyo yakakurudzirwa yekuisa mutsara ndeye 10-50 mg / L, inosiyana zvichienderana nemhando yemaruva. Semuyenzaniso, marozi anogona kurapwa ne 2% kugadzirwa yakadirwa ka200 (inenge 50 mg/L) nekunyika mhodzi kana kupfapfaidza. Azaleas inogona kupfapfaidzwa ne40-80 times dilution (inenge 25-50 mg/L) munguva yekukura kukurudzira lateral bud kukura. Paunenge uchipfira, mabhudzi kana nzvimbo dzekukura dzinofanira kuvharwa zvakaenzana, kudzivisa nguva dzepamusoro-tembiricha; inokurudzirwa kupfapfaidza mangwanani kana manheru. Migumisiro Yekushandisa: 6-BA inonyatso kuputsa bud dormancy, inokonzera kusiyanisa kwemaruva, uye inowedzera nhamba ye lateral buds, nekudaro inovandudza kusimba kwechirimwa uye maruva ekutumbuka. Semuenzaniso, kushandiswa kwayo pamiti yakadai semaapuro uye roses inogona kukurudzira lateral branch sprouting, iyo inobatsira pakuumba nekuchekerera. Nekudaro, zvinofanirwa kucherechedzwa kuti kushandisa zvakanyanya kunogona kukonzera kukura zvakanyanya kana kuremara. Inokurudzirwa kuitisa diki-diki kuyedza isati yatanga kushandiswa.
Chengetedzo: 6-BA ine kunonoka kufamba mukati mechirimwa uye inofanira kupfapfaidzwa yakananga panzvimbo yekushandisa. Kuibatanidza nemamwe maregulator akadai segibberellin (semuenzaniso, 100 mg/L 6-BA pamwe ne100 mg/L GA3) inogona kusimbisa bud-promoting effect. Chengetedza munzvimbo inotonhorera, yakaoma, kudzivisa zuva rakananga.
