I-Paclobutrazol (PBZ) iyi-aIsilawuli Sokukhula KwezitshalofuthiIsikhunta.Ingumphikisi owaziwayo we-hormone yesitshalo i-gibberellin.Ivimbela i-gibberellin biosynthesis, inciphisa ukukhula kwe-internodial ukuze inikeze iziqu eziqinile, ikhulise ukukhula kwezimpande, ibangele i-fruitet yokuqala kanye nokwandisa imbewu ezitshalweni ezinjengotamatisi nopelepele. I-PBZ isetshenziswa abatshali bezihlahla ukuze banciphise ukukhula kwamahlumela futhi kuboniswe ukuthi kunemiphumela emihle eyengeziwe ezihlahleni nasezihlahleni.Phakathi kwalezo kubalwa ukumelana nengcindezi yesomiso, amaqabunga aluhlaza okotshani, ukumelana okuphezulu nesikhunta namagciwane, kanye nokukhula okuthuthukile kwezimpande.Ukukhula kwe-Cambial, kanye nokukhula kwamahlumela, kuboniswe ukuthi kuncishisiwe kwezinye izinhlobo zezihlahla Abukho Ubuthi Obumelene Nezilwane Ezincelisayo.

Ukusetshenziswa

1. Ukutshala izithombo ezinamandla erayisini: Isikhathi esingcono kakhulu somuthi werayisi yiqabunga elilodwa, isikhathi senhliziyo eyodwa, okuyizinsuku ezingu-5-7 ngemva kokuhlwanyela. Isilinganiso esifanele sokusetshenziswa yimpushana emanzi engu-15% ye-paclobutrazol, ene-3 kilograms ngehektha ngalinye kanye namakhilogremu angu-1500 wamanzi angeziwe.

Ukuvimbela indawo yokulala irayisi: Ngesikhathi sokuhlangana kwerayisi (izinsuku ezingu-30 ngaphambi kokuhamba), sebenzisa amakhilogremu angu-1.8 ka-15% we-paclobutrazol powder wettable ehektheleni kanye namakhilogremu angu-900 wamanzi.

2. Hlakula izithombo eziqinile ze-rapeseed phakathi nesigaba samaqabunga amathathu, usebenzisa amagremu angu-600-1200 ka-15% we-paclobutrazol powder wettable ehektheleni kanye namakhilogremu angu-900 wamanzi.

3. Ukuze uvimbele ubhontshisi wesoya ekukhuleni ngokweqile ngesikhathi sokuqhakaza kokuqala, sebenzisa amagremu angu-600-1200 ka-15% we-paclobutrazol powder wettable ehektheleni bese wengeza amakhilogremu angu-900 wamanzi.

4. Ukulawulwa kokukhula kukakolweni kanye nokugqoka kwembewu ngokujula okufanele kwe-paclobutrazol kunesithombo esiqinile, ukutshala okukhulayo, ukuphakama okuncishisiwe, kanye nokwanda kwesivuno sikakolweni.

Ukunakwa

1. I-Paclobutrazol iyi-inhibitor eqinile yokukhula ene-half-life yeminyaka engu-0.5-1.0 enhlabathini ngaphansi kwezimo ezijwayelekile, kanye nesikhathi eside somphumela osele. Ngemva kokufafaza ensimini noma esigabeni sezithombo zemifino, kuvame ukuba nomthelela ekukhuleni kwezitshalo ezilandelayo.

2. Lawula ngokuqinile umthamo womuthi. Nakuba ukuphakama kwezidakamizwa kuphezulu, umphumela wokulawula ubude unamandla, kodwa ukukhula nakho kuyehla. Uma ukukhula kuhamba kancane ngemva kokulawula ngokweqile, futhi umphumela wokulawula ubude awukwazi ukutholakala ngesilinganiso esiphansi, inani elifanele lesifutho kufanele lifakwe ngokulinganayo.

3. Ukulawulwa kobude nokuhlakula kuncipha ngokwanda kwenani lokuhlwanyela, futhi inani lokuhlwanyela lelayisi elihlanganisiwe eliphuzi alidluli amakhilogremu angama-450 ngehektha. Ukusebenzisa amathila esikhundleni sezithombo kusekelwe ekuhlwanyeleni okungatheni. Gwema izikhukhula nokusebenzisa ngokweqile umanyolo we-nitrogen ngemuva kokufakwa.

4. Umphumela okhuthaza ukukhula we-paclobutrazol, i-gibberellin, ne-indoleacetic acid unomphumela ovimbelayo ovimbelayo. Uma umthamo uphezulu kakhulu futhi izithombo zivinjelwe ngokweqile, umanyolo we-nitrogen noma i-gibberellin ungengezwa ukuze uzihlenge.

5. Umphumela omncane we-paclobutrazol ezinhlotsheni ezahlukene zelayisi nokolweni uyahlukahluka. Lapho uyisebenzisa, kuyadingeka ukwandisa ngokuguquguqukayo noma ukunciphisa umthamo ngendlela efanele, futhi indlela yomuthi womhlabathi akufanele isetshenziswe.
