Idumela Elihle Lomsebenzisi Lomlawuli Wokukhula Kwezitshalo RH-5849 (1,2-dibenzoyl-1-(t-butyl)hydrazine) 20%WP

I-Paclobutrazol (PBZ) iyi-antioxidant enamandla.Umlawuli Wokukhula KwezitshalofuthiUkubulala isikhunta.Kungumphikisi owaziwayo we-hormone yesitshalo i-gibberellin.Kuvimbela i-gibberellin biosynthesis, kunciphisa ukukhula kwama-internodial ukuze kunikezwe iziqu eziqinile, kwandisa ukukhula kwezimpande, kubangele ukuvela kwezithelo kusenesikhathi futhi kwandise ukuvela kwembewu ezitshalweni ezifana notamatisi nopelepele. I-PBZ isetshenziswa ngabalimi bezitshalo ukunciphisa ukukhula kwehlumela futhi iboniswe ukuthi inemiphumela emihle eyengeziwe emithini nasezihlahleni.Phakathi kwalezo kukhona ukumelana okuthuthukisiwe nokucindezeleka kwesomiso, amaqabunga aluhlaza okotshani, ukumelana okuphezulu nesikhunta namagciwane, kanye nokuthuthukiswa okuthuthukisiwe kwezimpande.Ukukhula kwe-cambial, kanye nokukhula kwehlumela, kuye kwabonakala kunciphisa kwezinye izinhlobo zezihlahla. Akukho Ubuthi Ezincelisayo.

Ukusetshenziswa

1. Ukutshala izithombo eziqinile elayisini: Isikhathi esihle kakhulu somuthi ngelayisi yiqabunga elilodwa, isikhathi senhliziyo eyodwa, esingezinsuku ezingu-5-7 ngemva kokuhlwanyela. Isilinganiso esifanele sokusetshenziswa yi-15% yempuphu ye-paclobutrazol emanzi, enamakhilogremu angu-3 ngehektha kanye namakhilogremu angu-1500 amanzi angeziwe.

Ukuvimbela ukuminyana kwelayisi: Ngesikhathi sokuhlangana kwelayisi (izinsuku ezingu-30 ngaphambi kokutshala), sebenzisa amakhilogremu angu-1.8 empuphu ye-paclobutrazol engu-15% ngehektha kanye namakhilogremu angu-900 amanzi.

2. Hlakulela izithombo eziqinile ze-rapeseed ngesikhathi sesigaba samaqabunga amathathu, usebenzisa amagremu angu-600-1200 e-15% paclobutrazol wettable powder ngehektha ngalinye kanye namakhilogremu angu-900 amanzi.

3. Ukuvimbela ubhontshisi ekukhuleni ngokweqile ngesikhathi sokuqala sokuqhakaza, sebenzisa amagremu angu-600-1200 empuphu ye-paclobutrazol engu-15% ngehektha ngalinye bese ufaka amakhilogremu angu-900 amanzi.

4. Ukulawulwa kokukhula kukakolweni kanye nokufakwa kwembewu okune-paclobutrazol ejulile efanele kunezithombo ezinamandla, ukukhula kwe-tillering, ukuphakama okunciphile, kanye nomphumela wesivuno okhuphukile kukolweni.

Ukunaka

1. I-Paclobutrazol iyisivimbeli sokukhula esinamandla esinokuphila okuyingxenye yeminyaka engu-0.5-1.0 enhlabathini ngaphansi kwezimo ezijwayelekile, kanye nesikhathi eside somphumela osele. Ngemva kokufutha ensimini noma esigabeni sokutshala izithombo zemifino, kuvame ukuthinta ukukhula kwezilimo ezilandelayo.

2. Lawula ngokuqinile umthamo womuthi. Nakuba ukuhlushwa komuthi kuphakeme, umphumela wokulawula ubude uba namandla, kodwa ukukhula nakho kuncipha. Uma ukukhula kuhamba kancane ngemva kokulawula ngokweqile, futhi umphumela wokulawula ubude ungatholakali ngesilinganiso esiphansi, inani elifanele lokufafaza kufanele lisetshenziswe ngokulinganayo.

3. Ukulawulwa kobude kanye nokulima kuyancipha ngokwanda kwenani lokutshala, kanti inani lokutshala irayisi elihlanganisiwe eliphuzile alidluli amakhilogremu angu-450/hekthare. Ukusebenzisa ama-tiller ukufaka esikhundleni sezithombo kusekelwe ekuhlwanyeleni okuncane. Gwema ukukhukhula kanye nokusetshenziswa ngokweqile komanyolo we-nitrogen ngemva kokusetshenziswa.

4. Umphumela wokukhulisa we-paclobutrazol, i-gibberellin, kanye ne-indoleacetic acid unomphumela wokuvimbela ukuphikisana. Uma umthamo uphezulu kakhulu futhi izithombo zivinjelwe ngokweqile, umanyolo we-nitrogen noma i-gibberellin ungangezwa ukuze uzisindise.

5. Umphumela we-paclobutrazol wokufiphaza ezinhlotsheni ezahlukene zelayisi nokolweni uyahlukahluka. Uma uyisebenzisa, kubalulekile ukwandisa noma ukunciphisa umthamo ngendlela efanele, futhi akufanele kusetshenziswe indlela yokwelapha inhlabathi.
