Ukuhlelwa kwezithelo nokwandisa ukulawulwa kokukhula kwezitshalo - Thidiazuron (TDZ)
Izihlahla zezithelo ezinjengamagilebhisi, ama-apula, amapheya, amapentshisi, nama-cherries ngokuvamile zithinteka ngokushisa okuphansi kanye nesimo sezulu esibandayo, futhi inani elikhulu lezimbali nezithelo livame ukuwa, okuholela ekunciphiseni isivuno nokunciphisa izinzuzo zezomnotho. Ukwelashwa ngezilawuli zokukhula kwezitshalo akukwazi nje ukwandisa izinga lokumisa izithelo, kodwa futhi kukhuthaze ukukhulisa izithelo, ukwandisa isivuno kanye nekhwalithi, futhi kunciphise kakhulu amandla okusebenza kwabalimi bezithelo.
Yini i-Thidiazuron(TDZ)
I-Thidiazuron (TDZ) iyisilawuli sokukhula kwesitshalo se-urea. Ingasetshenziswa ngaphansi kwezimo eziphezulu zokuhlushwa ukotini, utamatisi ocutshungulwayo, upelepele nezinye izitshalo. Ngemva kokumuncwa amaqabunga ezitshalo, ingakhuthaza ukuchithwa kwamaqabunga ekuqaleni, okuwusizo ekuvuneni ngomshini. ; Isetshenziswa ngaphansi kwezimo eziphansi zokuhlushwa, inomsebenzi we-cytokinin futhi ingasetshenziswa kuma-apula, amapheya, amapentshisi, ama-cherry, amakhabe, amakhabe nezinye izitshalo ukwandisa izinga lokumisa izithelo, ukukhuthaza ukukhuliswa kwezithelo, nokwandisa isivuno kanye nekhwalithi.
Izici eziyinhloko ze-Thidiazuron(TDZ)
(1)I-Thidiazuron (TDZ) igcina izimbali nezithelo:
I-Thidiazuron (TDZ) iyi-cytokinin ekugxilweni okuphansi futhi inomsebenzi oqinile wezinto eziphilayo. Ingadala ukuhlukana kwamaseli ezitshalo kanye nezicubu ze-callus kangcono kunama-cytokinins ajwayelekile. Ngokuphindwe izikhathi ezingaphezu kwenkulungwane, lapho isetshenziswa phakathi nenkathi yokuqhakaza kwezihlahla zezithelo, ingenza i-parthenocarpy, ikhuthaze ukukhula kwe-ovary, ithuthukise ukuvundiswa kwempova, ivimbele ukwehla kwembali nezithelo, ngaleyo ndlela ikhulise kakhulu izinga lokumiswa kwezithelo.
(2) I-Thidiazuron (TDZ) ikhulisa izithelo:
I-Thidiazuron (TDZ) ingadala ukuhlukana kwamaseli ezitshalo futhi ikhuthaze ukuhlukana kwamaseli. Uma isetshenziswa esigabeni sezithelo ezincane, inomphumela obalulekile wokukhuthaza ekuhlukaniseni amaseli, futhi inokubili ukukhula okuvundlile nokuma mpo kwezitho. Ukukhuthaza umphumela, ngaleyo ndlela udlala indima yokukhulisa isithelo.
(3) I-Thidiazuron (TDZ) ivimbela ukuguga ngaphambi kwesikhathi:
Emazingeni aphansi, i-Thidiazuron (TDZ) yandisa i-photosynthesis, ikhuthaza ukuhlanganiswa kwe-chlorophyll emaqabunga, ikhuthaza umbala wamaqabunga ukuthi ujulise futhi uguquke ube luhlaza, yandisa isikhathi esiluhlaza, futhi ibambezela ukuguga kwamaqabunga.
(4)I-Thidiazuron (TDZ) Khulisa isivuno:
I-Thidiazuron (TDZ) yenza ukuhlukaniswa kwamaseli ezitshalo, ikhuthaze ukwanda okuqondile nokuvundlile kwezithelo ezisencane, ikhuthaze ukwanda ngokushesha kwezithelo ezincane, inciphise ingxenye yezithelo ezincane, futhi ikhulise kakhulu isivuno.
Ngakolunye uhlangothi, ingakhuthaza ukwakheka kwamaqabunga aluhlaza, ivimbele ukuguga kwamaqabunga ngaphambi kwesikhathi, ikhuthaze ukuthuthwa kwamaprotheni, ushukela nezinye izinto esithelweni, ikhulise ushukela esithelweni, ithuthukise ikhwalithi yesithelo, futhi ngcono ukudayiswa.
I-Thidiazuron(TDZ) izitshalo ezisebenzayo
I-Thidiazuron (TDZ) ingasetshenziswa kumagilebhisi, ama-apula, amapheya, amapentshisi, amadethi, amabhilikosi, ama-cherry nezinye izihlahla zezithelo, kanye nezitshalo zekhabe ezifana namakhabe namakhabe.
Ubuchwepheshe bokusebenzisa i-Thidiazuron(TDZ).
(1) Ukusetshenziswa kwe-Thidiazuron (TDZ) kumagilebhisi:
Yisebenzise okokuqala ezinsukwini eziyisi-5 ngemuva kokuqhakaza kwamagilebhisi, futhi uyisebenzise okwesibili ngokwehlukana kwezinsuku eziyi-10. Sebenzisa isixazululo samanzi esingu-0.1% we-Thidiazuron (TDZ) izikhathi eziyi-170 kuye kwezingama-250 (ixutshwe namanzi nge-10 ml ngayinye) 1.7 kuya ku-2.5 kg) fafaza ngokulinganayo, ugxile endlebeni, ungavimbela ngempumelelo ukuwohloka kwembali nezithelo, ukhuthaze ukukhula kwezithelo, futhi wenze izithelo ezingenambewu. . Isilinganiso sesisindo sohlamvu olulodwa sikhuphuka ngo-20%, isilinganiso sokuqukethwe okuqinile okuncibilikayo sifinyelela ku-18%, futhi isivuno singakhula size sifike ku-20%.
