Imisebenzi engu-7 emikhulu ye-gibberellin kanye nezinyathelo ezi-4 ezinkulu zokuqapha, abalimi kumele baqonde kusengaphambili ngaphambi kokusebenzisa

I-Gibberelliniyi-hormone yezitshalo etholakala kabanzi embusweni wezitshalo futhi ihileleke ezinkambisweni eziningi zezinto eziphilayo ezifana nokukhula nokukhula kwezitshalo.Ama-Gibberellins aqanjwa ngokuthi A1 (GA1) kuya ku-A126 (GA126) ngokohlelo lokutholwa.Inemisebenzi yokugqugquzela ukuhluma kwembewu nokukhula kwezitshalo, ukuqhakaza kwangaphambi kwesikhathi nokuthela izithelo, njll., futhi isetshenziswa kakhulu ezitshalweni zokudla ezihlukahlukene.

1. Umsebenzi wokuphila
I-Gibberelliniyinto ekhuthaza ukukhula kwezitshalo okunamandla kakhulu futhi jikelele.Ingakhuthaza ukwelulwa kwamaseli ezitshalo, ukunwebeka kwesiqu, ukunwetshwa kwamaqabunga, isheshise ukukhula nokuthuthuka, yenze izitshalo zivuthwe ngaphambi kwesikhathi, futhi yandise isivuno noma ithuthukise ikhwalithi;ingaphula i-dormancy, ikhuthaze ukuhluma;Isithelo sembewu;kungabuye kuguqule ubulili kanye nesilinganiso sezinye izitshalo, futhi kubangele ukuthi izitshalo ezithile ezihlala iminyaka emibili ziqhakaze kulo nyaka wamanje.

2. Ukusetshenziswa kwe-gibberellin ekukhiqizeni
(1) Khuthaza ukukhula, ukuvuthwa ngaphambi kwesikhathi kanye nokwandisa isivuno
Ukwelashwa kwemifino eminingi eluhlaza enamaqabunga nge-gibberellin kungasheshisa ukukhula futhi kwandise isivuno.Isilimo esidliwayo esinamagatsha anamanzi sifuthwa ngoketshezi oluyi-30~50mg/kg cishe uhhafu wenyanga ngemva kokuvuna, isivuno sikhuphuka ngamaphesenti angaphezu kuka-25%, iziqu namaqabunga ane-hypertrophic, futhi imakethe i-5~6d ekuseni.

(2) Phula i-dormancy futhi ukhuthaze ukuhluma
Ku-strawberry greenhouse kusizwa ukutshalwa kanye nokutshalwa kwe-semi-facilitative, emva kokumboza nokugcina ukushisa izinsuku ezintathu, okungukuthi, lapho kuvela ama-flower buds angaphezu kuka-30%, fafaza u-5 mL we-5 ~ 10 mg/kg ye-gibberellin isitshalo ngasinye, ugxile amaqabunga enhliziyo, angenza i-inflorescence ephezulu iqhakaze ngaphambi kwesikhathi., ukukhuthaza ukukhula kanye nokuvuthwa kusenesikhathi.
(3) Khuthaza ukukhula kwezithelo
Imifino yemelon kufanele ifuthwe ngoketshezi oluyi-2~3mg/kg ezithelweni ezisencane kanye esigabeni samakhabe amancane, okungakhuthaza ukukhula kwamakhabe amancane, kodwa ungafuthwanga amaqabunga ukuze ugweme ukwanda kwezimbali zesilisa.
(4) Nweba isikhathi sokugcina
Ukufafaza izithelo zamakhabe ngoketshezi oluyi-2.5~3.5mg/kg ngaphambi kokuvuna kungandisa isikhathi sokugcina.Ukufafaza isithelo ngoketshezi oluyi-50~60mg/kg ngaphambi kokuba ubhanana uvunwe kunomthelela othize ekwandiseni isikhathi sokugcina izithelo.I-Jujube, i-longan namanye ama-gibberellin nawo angabambezela ukuguga futhi andise isikhathi sokugcina.
(5) Shintsha isilinganiso sezimbali zesilisa nezinsikazi ukuze kwandiswe isivuno sembewu
Ukusebenzisa umugqa wekhukhamba wesifazane ekukhiqizeni imbewu, ukufafaza u-50-100 mg/kg woketshezi lapho izithombo zinamaqabunga eqiniso angama-2-6 kungenza ikhukhamba lensikazi libe yi-hermaphrodite, impova ephelele, futhi kwandise isivuno sembewu.
(6) Thuthukisa ukukhishwa kwesiqu nokuqhakaza, uthuthukise i-coefficient yokuzalanisa yezinhlobo eziphakeme
I-Gibberellin ingabangela ukuqhakaza kwemifino yezinsuku ezinde.Ukufafaza izitshalo noma izindawo zokukhula eziconsayo ngo-50 ~ 500mg/kg we-gibberellin kungenza izaqathe, iklabishi, ama-radishes, isilimo esidliwayo esinamagatsha anamanzi, iklabishi laseShayina nezinye izitshalo zokukhanya kwelanga ezikhula ngo-2a.Ukubhowula ngaphansi kwezimo zezinsuku ezifushane.
(7) Ukukhulula i-phytotoxicity ebangelwa amanye amahomoni
Ngemuva kokulimala kwemifino ngokweqile, ukwelashwa ngesisombululo se-2.5-5 mg/kg kungakhulula i-phytotoxicity ye-paclobutrazol ne-chlormethalin;Ukwelashwa ngesisombululo esingu-2 mg/kg kungadambisa i-phytotoxicity ye-ethylene.Utamatisi uyingozi ngenxa yokusetshenziswa ngokweqile kwe-anti-falling element, engakhululwa ngo-20mg/kg gibberellin.

3. Izindaba ezidinga ukunakwa
Inothi elisebenzayo:
1️⃣Landela ngokuqinile imithi yobuchwepheshe, futhi kuyadingeka ukuthola isikhathi esifanele, ukugxilisa ingqondo, indawo yokusetshenziswa, imvamisa, njll. yomuthi;
2️⃣Kuxhunyaniswe nezimo zangaphandle, ngenxa yokukhanya, izinga lokushisa, umswakama, izici zomhlabathi, kanye nezinyathelo ze-agronomic ezifana nezinhlobonhlobo, ukuvundisa, ukuminyana, njll., umuthi uzoba namazinga ahlukahlukene ethonya.Ukusetshenziswa kwezilawuli zokukhula kufanele kuhlanganiswe nezinyathelo ezivamile ze-agronomic;
3️⃣Ungasebenzisi kabi izilawuli zokukhula kwezitshalo.Isilawuli sokukhula kwesitshalo ngasinye sinesimiso saso sezinto eziphilayo, futhi umuthi ngamunye unemikhawulo ethile.Ungacabangi ukuthi kungakhathaliseki ukuthi hlobo luni lomuthi olusetshenziswayo, luzokwandisa ukukhiqizwa futhi lwandise ukusebenza kahle;
4️⃣Ungaxubani nezinto ezine-alkaline, i-gibberellin kulula ukuyinciphisa futhi yehluleke uma kukhona i-alkali.Kodwa ingaxutshwa nomanyolo oneasidi nengathathi hlangothi kanye nezibulala-zinambuzane, futhi ixutshwe ne-urea ukuze kwandiswe isivuno kangcono;
