Imisebenzi ye-7 enkulu ye-gibberellin kunye nezilumkiso ezi-4 eziphambili, abalimi kufuneka baqonde kwangaphambili ngaphambi kokusebenzisa

Gibberellinihomoni yesityalo ekhoyo ngokubanzi kwizityalo kwaye ibandakanyeka kwiinkqubo ezininzi zebhayoloji ezifana nokukhula kwezityalo kunye nophuhliso.I-Gibberellins ibizwa ngokuba yi-A1 (GA1) ukuya kwi-A126 (GA126) ngokomyalelo wokufumanisa.Inemisebenzi yokukhuthaza ukuntshula kwembewu kunye nokukhula kwezityalo, ukudubula kwangethuba kunye neziqhamo, njalo njalo, kwaye isetyenziswa kakhulu kwizityalo zokutya ezahlukeneyo.

1. Umsebenzi womzimba
Gibberellinyinto enamandla kakhulu kwaye ikhuthaza ukukhula kwezityalo ngokubanzi.Inokukhuthaza ukolulwa kweeseli zesityalo, ukwanda kwesiqu, ukwanda kwamagqabi, ikhawulezise ukukhula nophuhliso, yenza izityalo zivuthwe kwangethuba, kwaye zandise isivuno okanye ziphucule umgangatho;inokuphula i-dormancy, ikhuthaze ukuhluma;Imbewu yesiqhamo;inokutshintsha kwakhona isini kunye nomlinganiselo wezityalo ezithile, kwaye ibangele ukuba ezinye izityalo ezineminyaka emibini zidubule kulo nyaka.

2. Ukusetyenziswa kwe-gibberellin kwimveliso
(1) Ukukhuthaza ukukhula, ukukhula kwangoko kunye nokwandisa isivuno
Unyango lwemifuno emininzi eluhlaza kunye ne-gibberellin inokukhawulezisa ukukhula kunye nokwandisa isivuno.I Celery itshizwa ngolwelo oluyi 30 ~ 50mg/kg malunga nesiqingatha senyanga emva kokuvuna, isivuno sonyuka ngaphezu kwe 25%, iziqu kunye namagqabi abe hypertrophic, kwaye imarike 5~6d ekuseni.

(2) Yaphula i-dormancy kwaye ikhuthaze ukuhluma
Kwindlu yequnube encedisa ukulinywa kunye nokulinywa kancinci, emva kokugquma nokugcina kushushu iintsuku ezi-3, oko kukuthi, xa kuvele ngaphezulu kwe-30% yeentyatyambo, fafaza i-5 mL ye-5 ~ 10 mg/kg yesisombululo segibberellin kwisityalo ngasinye, ugxininise amagqabi entliziyo, anokwenza i-inflorescence ephezulu iqhakaze ngaphambi kwexesha., ukukhuthaza ukukhula kunye nokuvuthwa kwangoko.
(3) Ukukhuthaza ukukhula kweziqhamo
Imifuno yevatala kufuneka itshizwe nge 2~3mg/kg yolwelo kwiziqhamo eziselula kanye kwinqanaba levatala eselula, nto leyo enokukhuthaza ukukhula kweevatala eziselula, kodwa ungatshizi amagqabi ukunqanda ukwanda kwenani leentyatyambo zobuduna.
(4) Yandisa ixesha lokugcina
Ukutshiza iziqhamo zeevatala ngolwelo oluyi 2.5 ~ 3.5mg/kg phambi kokuvuna kunokwandisa ixesha lokugcina.Ukutshiza isiqhamo ngolwelo oluyi 50 ~ 60mg/kg phambi kokuba ibhanana ivunwe kunempembelelo ethile ekwandiseni ixesha lokugcinwa kweziqhamo.IJujube, i-longan kunye nezinye iigibberellins zinokulibazisa ukuguga kunye nokwandisa ixesha lokugcina.
(5) Guqula umlinganiselo weentyatyambo zenkunzi nemazi ukuze kwandiswe isivuno sembewu
Ukusebenzisa umgca we cucumber wemazi kwimveliso yembewu, ukutshiza i50-100 mg/kg yolwelo xa izithole zinamagqabi okwenene ayi 2-6 kungajika ikhukhamba elimazi libe yi hermaphrodite, ipollin epheleleyo, kwaye yandise isivuno sembewu.
(6) Ukukhuthaza ukutsalwa kwesiqu kunye nokudumba kweentyatyambo, phucula i-coefficient yokuzalisa yeentlobo ezikhethekileyo
I-Gibberellin inokubangela iintyatyambo zokuqala zemifuno yeentsuku ezinde.Ukutshiza izityalo okanye iindawo zokukhula ezivuzayo kunye ne-50 ~ 500mg / kg ye-gibberellin inokwenza iminqathe, iklabishi, i-radishes, i-celery, iklabishi yaseTshayina kunye nezinye izityalo ze-2a ezikhulayo zokukhanya kwelanga.Ukufakwa kwebholiti phantsi kweemeko zeentsuku ezimfutshane.
(7) Ukuphelisa i-phytotoxicity ebangelwa ngamanye amahomoni
Emva kokuba i-overdose yemifuno yonzakele, unyango kunye ne-2.5-5 mg / kg isisombululo sinokukhulula i-phytotoxicity ye-paclobutrazol kunye ne-chlormethalin;unyango kunye nesisombululo se-2 mg/kg sinokukhulula i-phytotoxicity ye-ethylene.Utamatisi unobungozi ngenxa yokusetyenziswa ngokugqithiseleyo kwezinto ezichasayo, ezinokukhululeka nge-20mg / kg gibberellin.

3. Imiba efuna ingqalelo
Qaphela kwisicelo esisebenzayo:
1️⃣ Landela ngokuthe ngqo iyeza lobugcisa, kwaye kuyimfuneko ukufumanisa ixesha elifanelekileyo, ugxininiso, indawo yesicelo, ukuphindaphinda, njl. iyeza;
2️⃣Ukulungelelaniswa neemeko zangaphandle, ngenxa yokukhanya, ubushushu, ukufuma, izinto zomhlaba, kunye nemilinganiselo ye-agronomic efana neentlobo ezahlukeneyo, ukuchumisa, ukuxinana, njl., iyeza liya kuba neempembelelo ezahlukeneyo.Ukusetyenziswa kwabalawuli bokukhula kufuneka kudityaniswe namanyathelo aqhelekileyo ezolimo;
3️⃣Musa ukusebenzisa kakubi izilawuli zokukhula kwezityalo.Umlawuli ngamnye wokukhula kwesityalo unomgaqo wakhe webhayoloji wokusebenza, kwaye ichiza ngalinye linemida ethile.Musa ukucinga ukuba kungakhathaliseki ukuba luhlobo luni lwechiza olusetyenziswayo, luya kwandisa imveliso kunye nokwandisa ukusebenza kakuhle;
4️⃣Musa ukuxubana nezinto ze-alkaline, i-gibberellin kulula ukuyinciphisa kwaye ingaphumeleli phambi kwe-alkali.Kodwa inokuxutywa kunye nezichumisi ezinomuncu kunye nezingathathi hlangothi kunye nezitshabalalisi, kwaye zixutywe ne-urea ukwandisa isivuno esingcono;
