Imisebenzi esi-7 ephambili ye-gibberellin kunye neendlela ezi-4 zokuzikhusela, abalimi kufuneka baziqonde kwangaphambili ngaphambi kokuba basebenzise

IGibberellinyi-hormone yezityalo ekhoyo kakhulu kubukumkani bezityalo kwaye ibandakanyeka kwiinkqubo ezininzi zebhayoloji ezifana nokukhula nophuhliso lwezityalo. IiGibberellins zibizwa ngokuba yi-A1 (GA1) ukuya kwi-A126 (GA126) ngokwendlela ezifunyenwe ngayo. Inemisebenzi yokukhuthaza ukuhluma kwembewu nokukhula kwezityalo, ukudubula kwangethuba kunye nokuchuma, njl.njl., kwaye isetyenziswa kakhulu kwizityalo ezahlukeneyo zokutya.

1. Umsebenzi wefiziyoloji
IGibberellinyinto enamandla kakhulu kwaye ikhuthaza ukukhula kwezityalo ngokubanzi. Ingakhuthaza ukwanda kweeseli zezityalo, ukwanda kwesiqu, ukwanda kwamagqabi, ikhawulezise ukukhula nophuhliso, yenze izityalo zivuthwe kwangoko, kwaye yonyuse isivuno okanye iphucule umgangatho; ingaphazamisa ukungavuthi, ikhuthaze ukuhluma; Isiqhamo sembewu; ingatshintsha isini kunye nomlinganiselo wezinye izityalo, kwaye ibangele ukuba ezinye izityalo ezineminyaka emibini zidubule kunyaka okhoyo.

2. Ukusetyenziswa kwe-gibberellin kwimveliso
(1) Khuthaza ukukhula, ukuvuthwa kwangethuba kwaye wandise isivuno
Ukunyanga imifuno emininzi eluhlaza enamagqabi nge-gibberellin kunokukhawulezisa ukukhula kwaye kwandise isivuno. I-Celery itshizwa ngolwelo lwe-30~50mg/kg malunga nesiqingatha senyanga emva kokuvunwa, isivuno sinyuka ngaphezulu kwe-25%, iziqu kunye namagqabi axineneyo, kwaye imarike ithengiswa emva kweentsuku ezi-5~6 kusasa.

(2) Yaphula ukungalali kakuhle kwaye ukhuthaze ukuhluma kwembewu
Kwindawo yokulima encediswa yi-strawberry greenhouse kunye nokulima okuncedisayo, emva kokugquma nokugcina ubushushu iintsuku ezi-3, oko kukuthi, xa kuvela amahlumela eentyatyambo angaphezu kwama-30%, fafaza i-5 mL yesisombululo se-gibberellin esingu-5 ~ 10 mg/kg kwisityalo ngasinye, ugxile kumagqabi entliziyo, anokwenza i-inflorescence ephezulu idubule kwangethuba. , ukukhuthaza ukukhula kunye nokuvuthwa kwangethuba.
(3) Khuthaza ukukhula kweziqhamo
Imifuno yemelon kufuneka itshizwe nge-2~3mg/kg yolwelo kwiziqhamo eziselula kanye xa sele zisekwinqanaba lemelon, nto leyo enokukhuthaza ukukhula kwemelon eziselula, kodwa ungatshizi amagqabi ukuze ungakhuphi inani leentyatyambo zesilisa.
(4) Yandisa ixesha lokugcina
Ukutshiza iziqhamo zeevatala ngolwelo lwe-2.5~3.5mg/kg ngaphambi kokuba kuvunwe kunokwandisa ixesha lokugcina. Ukutshiza iziqhamo ngolwelo lwe-50~60mg/kg ngaphambi kokuba ibhanana ivunwe kunefuthe elithile ekwandiseni ixesha lokugcina iziqhamo. I-Jujube, i-longan kunye nezinye ii-gibberellins nazo zinokulibazisa ukuguga kwaye zikwandise ixesha lokugcina.
(5) Tshintsha umlinganiselo weentyatyambo zesilisa nezesifazana ukuze kwandiswe isivuno sembewu
Ukusebenzisa umgca wekhukhamba eliyimazi ukuvelisa imbewu, ukutshiza i-50-100 mg/kg yolwelo xa izithole zinamagqabi okwenyani ama-2-6 kunokuguqula ikhukhamba eliyimazi libe yi-hermaphrodite, kugqibezele ukuvundiswa kwembewu, kwaye kwandise isivuno sembewu.
(6) Khuthaza ukutsalwa kwesiqu kunye nokudubula kweentyatyambo, phucula umlinganiselo wokuzala kweentlobo ze-elite
IGibberellin inokubangela ukudubula kwemifuno kwangethuba. Ukutshiza izityalo okanye iindawo zokukhula ezivuzayo nge-50~500mg/kg yegibberellin kunokwenza iminqathe, ikhaphetshu, iiradishes, iseleri, ikhaphetshu yaseTshayina kunye nezinye izityalo ezikhula kwilanga eli-2a. Ukugquma phantsi kweemeko zeentsuku ezimbalwa.
(7) Ukunciphisa ubuthi be-phytotoxicity obubangelwa zezinye iihomoni
Emva kokuba imifuno isebenzise kakhulu, unyango ngesisombululo se-2.5-5 mg/kg lunokunciphisa ubuthi be-paclobutrazol kunye ne-chlormethalin; unyango ngesisombululo se-2 mg/kg lunokunciphisa ubuthi be-ethylene. Itamatisi iyingozi ngenxa yokusetyenziswa kakhulu kwe-anti-falling element, enokuncitshiswa yi-20mg/kg ye-gibberellin.

3. Imiba efuna ingqwalasela
Qaphela xa usenza oku:
1️⃣Landela ngokungqongqo amayeza obuchwephesha, kwaye kuyimfuneko ukufumanisa ixesha elifanelekileyo, uxinaniso, indawo yokusetyenziswa, amaxesha afanelekileyo amayeza, njl.njl.;
2️⃣Ihambelana neemeko zangaphandle, ngenxa yokukhanya, ubushushu, ukufuma, izinto zomhlaba, kunye neendlela zokulinganisa ukulima ezifana nokwahluka, ukuchumisa, ubuninzi, njl.njl., iyeza liya kuba nefuthe elahlukileyo. Ukusetyenziswa kwabalawuli bokukhula kufuneka kudityaniswe neendlela zokulinganisa ukulima eziqhelekileyo;
3️⃣Musa ukusebenzisa kakubi abalawuli bokukhula kwezityalo. Umlawuli ngamnye wokukhula kwezityalo unomgaqo wakhe webhayoloji wokusebenza, kwaye ichiza ngalinye linemida ethile. Musa ukucinga ukuba nokuba loluphi uhlobo lwechiza olusetyenziswayo, luya kwandisa imveliso kwaye lunyuse ukusebenza kakuhle;
4️⃣Musa ukuxuba nezinto ze-alkaline, i-gibberellin kulula ukuyicoca kwaye ingaphumeleli xa kukho i-alkaline. Kodwa ingaxutywa nezichumisi ezine-asidi kunye nezingathathi cala kunye nezibulali zinambuzane, kwaye ixutywe ne-urea ukuze ivelise ngcono;
