Imirimo 7 yingenzi ya gibberellin hamwe ningamba 4 zingenzi, abahinzi bagomba gusobanukirwa mbere yo gukoresha

Gibberellinni imisemburo y'ibimera ibaho cyane mubwami bwibimera kandi igira uruhare mubikorwa byinshi byibinyabuzima nko gukura kw'ibimera no gukura. Gibberellins yitwa A1 (GA1) kugeza A126 (GA126) ukurikije gahunda yo kuvumbura. Ifite imirimo yo guteza imbere kumera kwimbuto no gukura kwibihingwa, kurabya hakiri kare no kwera imbuto, nibindi, kandi bikoreshwa cyane mubihingwa bitandukanye byibiribwa.

1. Imikorere ya physiologiya
Gibberellinni imbaraga zikomeye kandi rusange zikura ziteza imbere ibintu. Irashobora guteza imbere kurambura ingirabuzimafatizo, kurambura uruti, kwagura amababi, kwihuta gukura no gutera imbere, gutuma ibihingwa bikura hakiri kare, kandi byongera umusaruro cyangwa kuzamura ubwiza; irashobora guca ibitotsi, guteza imbere kumera; Imbuto z'imbuto; irashobora kandi guhindura igitsina nigipimo cyibimera bimwe na bimwe, kandi bigatera ibimera byimyaka ibiri kumurabyo mumwaka urangiye.

2. Gukoresha gibberellin mubikorwa
(1) Guteza imbere gukura, gukura hakiri kare no kongera umusaruro
Kuvura imboga rwatsi nyinshi zifite amababi hamwe na gibberelline birashobora kwihuta gukura no kongera umusaruro. Seleri yatewe hamwe na 30 ~ 50mg / kg y'amazi hafi igice cy'ukwezi nyuma yo gusarura, umusaruro wiyongereyeho hejuru ya 25%, ibiti n'amababi ni hypertrophique, kandi isoko ni 5 ~ 6d mugitondo.

(2) Gabanya ibitotsi kandi uteze kumera
Muri parike ya strawberry yafashaga guhinga no guhinga byoroheje, nyuma yo gupfuka no gukomeza gushyuha iminsi 3, ni ukuvuga, mugihe hagaragaye ibiti birenga 30% byindabyo, shyira mL 5 ya 5 ~ 10 mg / kg umuti wa gibberellin kuri buri gihingwa, wibande. umutima ugenda, ushobora gutuma inflorescence yo hejuru irabya mbere yigihe. , guteza imbere gukura no gukura hakiri kare.
(3) Guteza imbere gukura kwimbuto
Imboga za melon zigomba guterwa hamwe na 2 ~ 3mg / kg y'amazi ku mbuto zikiri nto ku cyiciro cya melon ikiri nto, zishobora guteza imbere imikurire ikiri nto, ariko ntutere amababi kugirango wirinde kwiyongera k'indabyo z'abagabo.
(4) Ongera igihe cyo kubika
Gutera imbuto za melon hamwe na 2.5 ~ 3.5mg / kg y'amazi mbere yo gusarura bishobora kongera igihe cyo kubika. Gutera imbuto hamwe na 50 ~ 60mg / kg y'amazi mbere yuko igitoki gisarurwa gifite ingaruka runaka mukwongerera igihe cyo kubika imbuto. Jujube, longan hamwe na gibberelline irashobora kandi gutinza gusaza no kongera igihe cyo kubika.
(5) Hindura igipimo cyindabyo zumugabo nigitsina gore kugirango wongere imbuto
Gukoresha umurongo wimyumbati kugirango utange imbuto, gutera 50-100 mg / kg byamazi mugihe ingemwe zifite amababi yukuri 2-6 arashobora guhindura imyumbati yumugore muri hermafrodite, kwanduza byuzuye, no kongera umusaruro wimbuto.
(6) Guteza imbere gukuramo ururabyo no kurabyo, kunoza coefficient yubworozi bwubwoko bwiza
Gibberellin irashobora gutera indabyo hakiri kare imboga zigihe kirekire. Gutera ibimera cyangwa gutonyanga ingingo zikura hamwe na 50 ~ 500mg / kg ya gibberelline irashobora gukora karoti, imyumbati, radis, seleri, imyumbati yubushinwa nibindi bihingwa byizuba 2a bikura. Guhindagurika mugihe gito.
(7) Kuraho phytotoxicity iterwa nindi misemburo
Nyuma yo kunywa imboga zirenze urugero, kuvura umuti wa mg / kg 2,5-5 bishobora kugabanya phytotoxicity ya paclobutrazol na chlormethalin; kuvura hamwe na 2 mg / kg igisubizo gishobora kugabanya phytotoxicity ya Ethylene. Inyanya ni mbi kubera gukoresha cyane ibintu birwanya kugwa, bishobora koroherezwa na 20mg / kg gibberellin.

3. Ibintu bikeneye kwitabwaho
Icyitonderwa mubikorwa bifatika:
1️⃣Kurikiza byimazeyo imiti ya tekiniki, kandi birakenewe kumenya igihe cyiza, kwibanda, aho wasabye, inshuro, nibindi byimiti;
2️⃣ Bihujwe n’imiterere yo hanze, kubera urumuri, ubushyuhe, ubushuhe, ibintu byubutaka, hamwe ningamba zubuhinzi nkubwoko butandukanye, ifumbire, ubwinshi, nibindi, ibiyobyabwenge bizagira ingaruka zitandukanye. Ikoreshwa ryabashinzwe gukura bigomba guhuzwa ningamba zisanzwe zubuhinzi;
3️⃣Ntugakoreshe nabi ibimera bikura. Buri muteguro wo gukura kw'ibimera afite ihame ryibinyabuzima ryibikorwa, kandi buri muti ufite aho ugarukira. Ntutekereze ko niyo ibiyobyabwenge byakoreshwa gute, bizongera umusaruro kandi byongere imikorere;
4️⃣Ntukavange nibintu bya alkaline, gibberellin biroroshye kubogama no kunanirwa imbere ya alkali. Ariko irashobora kuvangwa nifumbire ya acide kandi idafite aho ibogamiye hamwe nudukoko twica udukoko, ikavangwa na urea kugirango umusaruro wiyongere;
