Zikhula Kanjani Izimpande Ze-Fibrous?
Izinhlelo zezimpande zidlala indima ebalulekile ekukhuleni kwezitshalo; ngenxa yalokho, inqubo yokwakhiwa kwezimpande iyisihloko esibalulekile kwezolimo.
Amasistimu ezimpande zezitshalo ngokuvamile ahlukaniswa ngezinhlobo ezimbili ezinkulu: amasistimu we-taproot kanye nesistimu yezimpande ze-fibrous. Ukusuka eningizimu kuya ezifundeni ezisenyakatho, izitshalo eziyinhloko—njengokolweni, irayisi, nommbila—ngokuyinhloko zinezimpande ezinemicu.
Izimpande ezinama-fibrous zimelela i-root morphology evamile etholakala ezitshalweni ze-monocotyledonous. Ngokushesha ngemva kokuhluma kwembewu, impande yokuqala iba nokuwohloka; kamuva, izimpande ezifikayo ziyavela ngaphansi kwe-hypocotyl noma kusukela phansi kwesiqu esincane-lezi zaziwa ngokuthi izimpande ezine-fibrous. Sikhethe ummbila—isibonelo esimele isitshalo esinezimpande—ukuze sihlole ukusebenza kahle komkhiqizo ohamba phambili we-Pinsoa wokuthuthukisa ukukhula kwezimpande ezine-fibrous: INDOLE-3-BUTYRIC ACID POTASSIUM SALT (IBA-K).
Imiphumela elandela ukusetshenziswa kwe-IBA-K nge-fertigation ikhonjisiwe ngezansi:
1. Iqembu lokwelapha libonise uhlelo lwempande olubanzi kakhulu kanye nemicu yezimpande ezinde uma kuqhathaniswa neqembu lokulawula.
2. Eqenjini lokulawula, isisindo esisha sasingu-13.1 g, futhi impande isisindo esisha sasingu-6.5 g.
3. Eqenjini lokuhlola, isisindo esisha sasingu-17.2 g, kanti impande isisindo esisha sasingu-8.1 g.
Le miphumela ikhombisa ukuthi izithombo zommbila eziphathwe nge-IBA-K ziqine kakhulu, zineziqu ezijiyile kanye namahlamvu aluhlaza. Ngaphezu kwalokho, bakha uhlelo lwezimpande oluningi futhi olude, olunesisindo esiphelele sesitshalo kanye nesisindo sezimpande esisha ukwedlula ngokuphawulekayo lezo zeqembu lokulawula.
Mayelana ne-Pinsoa IBA-K
I-Pinsoa IBA-Kiveza njengokuqinile okucwebezelayo okumhlophe okuncibilika kalula emanzini futhi kuncibilika kuzincibilikisi zezinto eziphilayo njenge-acetone, i-ethanol, ne-diethyl ether. Ibonisa umsebenzi ophezulu wezinto eziphilayo kune-indole-3-butyric acid (IBA) ngokwayo; nokho, njengoba ibola kancane lapho ichayeke ekukhanyeni okunamandla, kunconywa ukugcinwa endaweni evikela ukukhanya. Lo mkhiqizo umunca kalula futhi usetshenziswe izitshalo, ugxile ikakhulukazi ezindaweni zokukhula ukuze ukhuthaze ukuhlukana kwamaseli. Ikhuthaza ngokuphumelelayo ukwakheka kwezimpande ze-adventitious, okuholela ohlelweni lwezimpande olubonakala ngobuningi obukhulu, ukukhula okuqondile, ukushuba okukhulayo, nobuningi bezinwele zezimpande. Izindlela ezijwayelekile zokufaka isicelo zifaka ukucwiliswa kwezimpande, ukucwiliswa emanzini, ukuvundisa, nokugqoka imbewu.
