I-Paclobutrazol iyisilawuli sokukhula kwezitshalo kanye ne-fungicide, i-retardant yezitshalo, ebizwa nangokuthi i-inhibitor. Ingakhuphula okuqukethwe kwe-chlorophyll, amaprotheni kanye ne-nucleic acid esitshalweni, inciphise okuqukethwe kwe-erythroxin ne-indole acetic acid, ikhulise ukukhululwa kwe-ethylene, ikhulise ukumelana nendawo yokulala, isomiso, amakhaza nezifo, ikhulise isivuno, ithuthukise ikhwalithi futhi Ithuthuke. ukusebenza kahle kwezomnotho. Inobuthi obuphansi kubantu, imfuyo, izinkukhu nezinhlanzi, futhi ukusetshenziswa kwayo ekukhiqizeni imifino kudlala indima ebalulekile ekwandiseni umkhiqizo kanye nokwenza ngcono izinga.
Ukusetshenziswa kwe-paclobutrazol kwezolimo
1. Hlakulela izithombo eziqinile
Lapho izithombo zama-eggplant, amakhabe neminye imifino ikhula imilenze, ungafafaza u-50-60 kg we-200-400ppm uketshezi ngehektare ngalinye esigabeni samaqabunga angama-2-4 ukuvimbela ukwakheka "kwezithombo ezinde" futhi uthuthukise izithombo ezimfushane neziqinile. . Isibonelo, lapho utshala izithombo zekhukhamba, ukuchela noma ukuchelela ngesisombululo se-paclobutrazol esingu-20 mg/L eqabungeni eli-1 kanye nesiteji senhliziyo esi-1 sezithombo kumathreyi epulaki kungathuthukisa ikhwalithi yezithombo futhi kukhiqize izithombo ezimfushane neziqinile.
Uma ukhulisa izithombo zikapelepele, fafaza uketshezi lwe-paclobutrazol ngo-5 kuya ku-25 mg/L esigabeni samaqabunga ama-3 ukuya kwangu-4 ukuze uhlakulele izithombo eziqinile. Uma ukhulisa izithombo zikatamatisi, fafaza uketshezi lwe-paclobutrazol ngo-10-50 mg/L lapho izithombo zisesigabeni samaqabunga angu-2-3 ukuze zinciphise izitshalo futhi zivikele ukuthi zingakhuli kakhulu.
Esigabeni samaqabunga ama-3 sikatamatisi wasekwindla, fafaza ngesisombululo se-paclobutrazol esingu-50-100 mg/L ukuze uhlakulele izithombo ezinamandla.
Ekutshalweni kwezithombo zepulaki likatamatisi, amaqabunga ama-3 nenhliziyo eyodwa kufafazwa ngesisombululo se-paclobutrazol esingu-10 mg/L.
Uma ukhulisa izithombo zesitshalo seqanda, fafaza isixazululo se-paclobutrazol esingu-10-20 mg/L emaqabungeni angu-5-6 ukuze unciphise izithombo futhi uzivikele ekukhuleni kakhulu.
Uma ukhulisa izithombo zeklabishi, fafaza i-paclobutrazol engu-50 kuya ku-75 mg/L emaqabunga ama-2 nenhliziyo eyodwa, okungenza izithombo zikhule ziqine futhi zikhule zibe izithombo ezifushane neziqinile.
2. Lawula ukukhula ngokweqile
Ngaphambi kokutshala, cwilisa izimpande zikapelepele ngesisombululo se-paclobutrazol esingu-100 mg/L imizuzu engu-15 ngaphambi kokutshala. Fafaza ngesisombululo se-paclobutrazol esingu-25 mg/L noma esingu-50 mg/L cishe ezinsukwini eziyi-7 ngemva kokutshala; uma isikhathi sokukhula siqine kakhulu, sebenzisa i-100~ Ukufafaza u-200 mg/L we-paclobutrazol liquid kungafinyelela umphumela wezitshalo ezincane futhi kuvimbele ukukhula kwemilenze.
Esigabeni sokuqala sokukhula kukabhontshisi oluhlaza, ukufafaza ngoketshezi lwe-paclobutrazol ngo-50 kuye ku-75 mg/L kungathuthukisa ukwakheka kwabantu, kuthuthukise i-photosynthesis, futhi kuvimbele ukukhula okunemilenze, ngaleyo ndlela kwandise inani lama-inflorescence esiqwini esikhulu ngo-5% kuye ku-10% futhi izinga lokusetha i-pod cishe ngama-20%.
Uma i-edamame inamaqabunga ama-5 kuya kwayi-6, yifafaze ngo-50 kuya ku-75 mg/L we-paclobutrazol liquid ukuze wenze iziqu ziqine, ufinyeze ama-internodes, ukhuthaze amagatsha, futhi ukhule kancane ngaphandle kokuba nemilenze.
Uma ubude besitshalo bungama-40 kuya ku-50 cm, fafaza u-300 mg/L we-paclobutrazol liquid kusukela ekuqaleni kuka-August kuya ekuqaleni kuka-September, kanye njalo ezinsukwini eziyi-10, bese ufutha izikhathi ezi-2 kuya kwezi-3 ngokuqhubekayo ukuze ulawule ukukhula.
Izithombo zikatamatisi kufanele zifafazwe ngesisombululo se-paclobutrazol esingu-25 mg/L cishe ezinsukwini eziyi-7 ngemuva kokufakelwa kabusha; Ukufafaza ngesisombululo se-paclobutrazol esingu-75 mg/L ngemva kokunciphisa izithombo kungavimbela ukukhula kwemilenze futhi kukhuthaze ukukhula kwezitshalo.
Esigabeni samaqabunga ama-3, ukufafaza ubulembu bokhula lwasolwandle ngo-200 mg/L we-paclobutrazol liquid kungalawula ukukhula ngokweqile futhi kwandise isivuno cishe ngama-26%.
3. Khulisa ukukhiqizwa
Esigabeni sezithombo noma esigabeni sokuchuma sezimpande, isiqu kanye nemifino yamaqabunga, ukufafaza amakhilogremu angama-50 we-200~300ppm isixazululo se-paclobutrazol ngehektare kungakhuthaza ukujiya kwamaqabunga emifino, ukufinyezwa kwama-internode, izitshalo ezinamandla, ikhwalithi ethuthukisiwe, nokwanda kwesivuno. Isibonelo, ngaphambi kokukha ukhukhamba, fafaza ngesisombululo se-paclobutrazol esingu-400 mg/L ukuze ukhuphule isivuno cishe ngo-20% kuya ku-25%.
Esigabeni samaqabunga ama-4 wamakhukhamba ekwindla ezindlini zokugcina izithombo, fafaza uketshezi lwe-paclobutrazol ngo-100 mg/L ukuze ufinyeze ama-internodes, uhlanganise ukuma kwesitshalo, futhi ujiye iziqu. Ukumelana ne-powdery mildew kanye ne-downy mildew kuyathuthukiswa, ukumelana nokubanda kuba ngcono, futhi izinga lokumisa izithelo liyakhula. , izinga lokukhuphuka kwesivuno lifinyelela cishe ku-20%.
Esigabeni samaqabunga ama-3-4 eklabishi laseShayina, ukufafaza izitshalo ngesisombululo se-paclobutrazol esingu-50-100 mg/L kungenza izitshalo zibe mncane futhi kwandise inani lembewu cishe ngo-10% -20%.
Uma isithombo sinamaqabunga eqiniso angu-3 kuya kwangu-4, fafaza ngesisombululo se-paclobutrazol esingu-45 mg/L ukuze uthuthukise ukumelana nokunciphisa ukwenzeka; ngesikhathi sesigaba sokwakheka kwezimpande ezinamanzi, yifafaze ngesisombululo se-paclobutrazol esingu-100 mg/L ukuvimbela ukukhula kwezitshalo. Ivimbela ukubopha, yenza isitshalo sishiye amaqabunga abe luhlaza, yenza amaqabunga abe mafishane futhi aqonde, ithuthukise i-photosynthesis, futhi ikhuthaze ukuthuthwa kwemikhiqizo ye-photosynthetic ezimpandeni eziyinyama, engakhuphula isivuno ngo-10% kuya ku-20%, ivimbele ama-bran cores, futhi ithuthukise ukudayiswa. .
Ukufafaza i-edamame ngoketshezi oluyi-100 kuya ku-200 mg/L lwe-paclobutrazol phakathi nesigaba sokuqala sokuqhakaza kwezimbali kungakhuphula amagatsha asebenzayo, inombolo ye-pod ephumelelayo nesisindo se-pod, futhi kwandise isivuno cishe ngo-20%. Uma imivini ikhuphukela phezulu eshalofini, fafaza i-yam ngoketshezi lwe-paclobutrazol oluyi-200 mg/L. Uma ukukhula kunamandla kakhulu, fafaza kanye njalo ezinsukwini ezi-5 kuya kweziyi-7, bese ufutha izikhathi ezi-2 kuya kwezi-3 ngokuqhubekayo ukuze uvimbele ukukhula kweziqu namaqabunga futhi ukhuthaze ukuhluma kwamagatsha aseceleni. Izimbali ziyakhula, izilimo eziyizigaxa ziyakhula, futhi isivuno sikhuphuka cishe ngo-10%.
4. Nyusa imiphumela yangaphambi kwesikhathi
Umanyolo we-nitrogen omningi usetshenziswa ensimini yemifino, noma imifino ifakwe umthunzi futhi ukukhanya akwanele, noma umswakama wemifino endaweni evikelekile uphezulu ebusuku, njll., okuvame ukudala isiqu semifino namaqabunga ukuba abe side, esithinta ukukhula kokuzala kanye nesimo sezithelo. Ungafafaza u-50 kg we-200ppm liquid ihektha ngalinye ukuze uvimbele Iziqu namaqabunga anemilenze, ekhuthaza ukukhula kokuzala kanye nokuthela ngokushesha. Ngesikhathi sokwakheka kwezimpande ezinamanzi, ukufafaza isixazululo se-paclobutrazol esingu-100-150 mg/L emaqabunga, amalitha angama-30-40 ngehektare ngalinye, kungalawula ukukhula kwezingxenye ezingenhla komhlaba futhi kukhuthaze i-hypertrophy yezimpande ezinomzimba. Naka ukugxila okunembile komuthi kanye nokufafaza okufanayo. Khuthaza ukuvuthwa kwezithelo. Ngemuva kwezithelo, fafaza ngesisombululo se-paclobutrazol esingu-500 mg/L ukuvimbela ukukhula kwezitshalo nokukhuthaza ukuvuthwa kwezithelo.
Izinyathelo zokuzivikela
Lawula ngokuqinile inani nesikhathi somuthi. Uma sonke isitshalo sifafazwa, ukuze kwandiswe ukunamathela koketshezi, engeza inani elifanele lempushana yokuwasha engathathi hlangothi oketshezini. Uma umthamo mkhulu kakhulu futhi ukugxila kuphezulu kakhulu, okwenza ukukhula kwezitshalo kuvinjelwe, ungakwazi ukwandisa ukufakwa komanyolo osebenza ngokushesha, noma usebenzise i-gibberellin (92O) ukuze udambise inkinga. Sebenzisa u-0.5 kuya ku-1 amagremu ihektare ngalinye bese ufafaza amanzi angamakhilogremu angama-30 kuye kwangama-40.
