Imisebenzi emikhulu engu-7 ye-gibberellin kanye nezinyathelo zokuqapha ezine ezinkulu, abalimi kumele baziqonde kusenesikhathi ngaphambi kokusebenzisa

I-Gibberelliniyi-hormone yezitshalo ekhona kabanzi embusweni wezitshalo futhi ihilelekile ezinqubweni eziningi zezinto eziphilayo njengokukhula nokuthuthukiswa kwezitshalo. Ama-Gibberellin abizwa ngokuthi i-A1 (GA1) kuya ku-A126 (GA126) ngokulandelana kokutholakala kwawo. Inemisebenzi yokukhuthaza ukuhluma kwembewu nokukhula kwezitshalo, ukuqhakaza kwezimbali nokukhiqiza izithelo, njll., futhi isetshenziswa kabanzi ezitshalweni zokudla ezahlukahlukene.

1. Umsebenzi we-physiological
I-Gibberelliniyisithako esinamandla kakhulu nesijwayelekile esikhuthaza ukukhula kwezitshalo. Ingakhuthaza ukwanda kwamaseli ezitshalo, ukwanda kwesiqu, ukwandiswa kwamaqabunga, isheshise ukukhula nentuthuko, yenze izitshalo zivuthwe kusenesikhathi, futhi yandise isivuno noma ithuthukise ikhwalithi; ingaphazamisa ukungavuki, ikhuthaze ukuhluma; Izithelo zembewu; ingashintsha futhi ubulili kanye nesilinganiso sezinye izitshalo, futhi ibangele ukuthi ezinye izitshalo ezikhula iminyaka emibili ziqhakaze onyakeni wamanje.

2. Ukusetshenziswa kwe-gibberellin ekukhiqizeni
(1) Khuthaza ukukhula, ukuvuthwa kusenesikhathi futhi wandise isivuno
Ukwelashwa kwemifino eminingi eluhlaza enamaqabunga nge-gibberellin kungasheshisa ukukhula futhi kwandise isivuno. I-celery ifuthwa ngoketshezi olungama-30~50mg/kg cishe ngemva kwengxenye yenyanga ngemva kokuvunwa, isivuno sanda ngaphezu kwama-25%, iziqu namaqabunga aqinile, kanti imakethe itholakala emahoreni angu-5~6 ekuseni.

(2) Hlukanisa ukungalali kahle futhi ukhuthaze ukuhluma kwembewu
Ekulimeni okusizwa yi-greenhouse yama-strawberry kanye nasekulimeni okusiza kancane, ngemva kokumboza nokugcina kufudumele izinsuku ezi-3, okungukuthi, lapho kuvela amahlumela ezimbali angaphezu kuka-30%, fafaza isixazululo se-gibberellin esingu-5 ~ 10 mg/kg ngesitshalo ngasinye, ugxile emaqabungeni enhliziyo, angenza i-inflorescence ephezulu iqhakaze kusenesikhathi. , ukukhuthaza ukukhula nokuvuthwa kwasekuqaleni.
(3) Khuthaza ukukhula kwezithelo
Imifino ye-melon kufanele ifuthwe ngo-2 ~ 3mg/kg woketshezi ezithelweni ezincane kanye esigabeni se-melon encane, okungakhuthaza ukukhula kwe-melon encane, kodwa ungafuthi amaqabunga ukuze ugweme ukwanda kwenani lezimbali zesilisa.
(4) Yandisa isikhathi sokugcina
Ukufutha izithelo zamakhabe ngoketshezi oluyi-2.5~3.5mg/kg ngaphambi kokuvuna kungandisa isikhathi sokugcina. Ukufutha izithelo ngoketshezi oluyi-50~60mg/kg ngaphambi kokuba ubhanana uvunwe kunomthelela othile ekwandiseni isikhathi sokugcina izithelo. I-Jujube, i-longan kanye nezinye i-gibberellin nakho kungabambezela ukuguga futhi kwandise isikhathi sokugcina.
(5) Shintsha isilinganiso sezimbali zesilisa nezesifazane ukuze kwandiswe isivuno sembewu
Ukusebenzisa umugqa wekhukhamba labesifazane ekukhiqizeni imbewu, ukufafaza u-50-100 mg/kg woketshezi lapho izithombo zinamaqabunga angempela angu-2-6 kungenza ikhukhamba labesifazane libe yi-hermaphrodite, kuqedele ukuvundisa impova, futhi kwandise isivuno sembewu.
(6) Khuthaza ukukhishwa kwesiqu nokuqhakaza, thuthukisa i-coefficient yokuzalanisa kwezinhlobo eziphezulu
I-Gibberellin ingadala ukuqhakaza kwemifino yosuku olude kusenesikhathi. Ukufutha izitshalo noma izindawo zokukhula eziconsayo nge-50~500mg/kg ye-gibberellin kungenza izaqathi, iklabishi, ama-radishes, i-celery, iklabishi yaseShayina kanye nezinye izitshalo ezikhula ngokukhanya kwelanga okuphindwe kabili. Ukuqhakaza ngaphansi kwezimo zezinsuku ezimfushane.
(7) Ukuqeda ubuthi obubangelwa amanye ama-hormone
Ngemva kokulimala kokusebenzisa imifino ngokweqile, ukwelashwa ngesisombululo esingu-2.5-5 mg/kg kunganciphisa ubuthi be-paclobutrazol kanye ne-chlormethalin; ukwelashwa ngesisombululo esingu-2 mg/kg kunganciphisa ubuthi be-ethylene. Utamatisi uyingozi ngenxa yokusetshenziswa ngokweqile kwe-anti-falling element, okungancishiswa yi-20 mg/kg gibberellin.

3. Izindaba ezidinga ukunakwa
Qaphela ekusebenzeni okungokoqobo:
1️⃣Landela ngokuqinile umuthi wezobuchwepheshe, futhi kuyadingeka ukuthola isikhathi esifanele, ukuhlushwa, indawo yokusetshenziswa, imvamisa, njll. yomuthi;
2️⃣Kuhambisana nezimo zangaphandle, ngenxa yokukhanya, izinga lokushisa, umswakama, izici zenhlabathi, kanye nezilinganiso zezolimo ezifana nokuhlukahluka, umanyolo, ubuningi, njll., umuthi uzoba nethonya elihlukahlukene. Ukusetshenziswa kwezilawuli zokukhula kufanele kuhlanganiswe nezinyathelo zezolimo ezivamile;
3️⃣Ungasebenzisi kabi abalawuli bokukhula kwezitshalo. Umlawuli ngamunye wokukhula kwezitshalo unesimiso sakhe sezinto eziphilayo sokusebenza, futhi umuthi ngamunye unemikhawulo ethile. Ungacabangi ukuthi kungakhathaliseki ukuthi uhlobo luni lomuthi olusetshenziswayo, luzokwandisa umkhiqizo futhi lukhulise ukusebenza kahle;
4️⃣Ungaxubani nezinto ze-alkaline, i-gibberellin kulula ukuyiqeda futhi yehluleke uma kukhona i-alkaline. Kodwa ingaxutshwa nomanyolo we-acidic kanye nowokungathathi hlangothi kanye nezibulala-zinambuzane, futhi ixutshwe ne-urea ukuze kwandiswe isivuno kangcono;
