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, ngemva kokumboza nokufudumala izinsuku ezintathu, okungukuthi, lapho kuvela ama-flower buds angaphezu kuka-30%, fafaza u-5 ml wesisombululo se-gibberellin esingu-5 ~ 10 mg/kg esitshalweni ngasinye, ugxile emaqabunga enhliziyo, angenza i-inflorescence ephezulu iqhume ngaphambili. , 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 eziconsisayo 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 ezimfushane.
(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 nethonya elihlukahlukene. 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;
