Imirimo 7 y'ingenzi ya gibberellin n'uburyo 4 bw'ingenzi bwo kwirinda, abahinzi bagomba gusobanukirwa mbere yo gukoresha

Gibberellinni imisemburo y'ibimera iboneka cyane mu bwami bw'ibimera kandi igira uruhare mu bikorwa byinshi by'ibinyabuzima nko gukura no gukura kw'ibimera. Gibberellins yitwa A1 (GA1) kuva kuri A126 (GA126) hakurikijwe uko ibintu bikurikirana. Ifite inshingano zo guteza imbere imikurire y'imbuto no gukura kw'ibimera, kurabya indabyo no kwera imbuto kare, nibindi, kandi ikoreshwa cyane mu bihingwa bitandukanye by'ibiribwa.

1. Imikorere y'umubiri
Gibberellinni ikintu gikomeye cyane kandi gitera gukura kw'ibimera muri rusange. Gishobora gutuma uturemangingo tw'ibimera turushaho kurekura, uburebure bw'igiti, kwaguka kw'amababi, kwihutisha gukura no gukura, gutuma ibihingwa byera vuba, kandi bikongera umusaruro cyangwa bikanoza ubwiza; gishobora guhagarika igihe cyo kumera, kigatuma ibimera bimera neza; Imbuto z'imbuto; gishobora kandi guhindura igitsina n'ikigereranyo cy'ibimera bimwe na bimwe, kandi kigatuma bimwe mu bimera bimara imyaka ibiri birabya mu mwaka ushize.

2. Gukoresha gibberellin mu gukora
(1) Guteza imbere iterambere, gukura vuba no kongera umusaruro
Gukoresha gibberellin mu kuvura imboga nyinshi z’icyatsi kibisi bishobora kwihutisha gukura no kongera umusaruro. Seleri iterwa amazi angana na 30 ~ 50mg / kg mu gihe cy'amezi atatu nyuma yo gusarurwa, umusaruro wiyongeraho ibirenze 25%, amashami n'amababi birakomeye cyane, kandi isoko riba amasaha 5 ~ 6 mu gitondo.

(2) Guhagarika igihe cyo kurara no guteza imbere kumera kw'imbuto
Mu buhinzi bw’imbuto z’ibimera bifasha mu guhinga no guhinga mu buryo bworoshye, nyuma yo gupfuka no kubika ubushyuhe mu minsi 3, ni ukuvuga ko iyo indabyo zisaga 30% zivutse, tera umuti wa gibberellin wa 5-10 mg/kg kuri buri gihingwa, wibanda ku mababi y’umutima, ashobora gutuma indabyo zo hejuru zitangira kurabya mbere y’igihe. , kugira ngo birusheho gukura no gukura vuba.
(3) Guteza imbere ikura ry'imbuto
Imboga za melon zigomba gusukwaho 2 ~ 3mg / kg y'amazi ku mbuto ntoya rimwe mu gihe cy'ikiruhuko cy'amahwa, ibi bishobora gutuma amahwa ntoya akura, ariko ntugatere amababi kugira ngo wirinde kwiyongera kw'indabo z'abagabo.
(4) Kongera igihe cyo kubika
Gutera imbuto z'amahumyo amazi angana na 2.5 ~ 3.5mg / kg mbere yo gusarura bishobora kongera igihe cyo kubika. Gutera imbuto amazi angana na 50 ~ 60mg / kg mbere yo gusarura igitoki bigira ingaruka ku kongera igihe cyo kubika imbuto. Jujube, longan n'izindi gibberellin nabyo bishobora gutinda gusaza no kongera igihe cyo kubika.
(5) Hindura igipimo cy'indabyo z'ingabo n'iz'ingore kugira ngo wongere umusaruro w'imbuto
Gukoresha umurongo w'inkeri mu gutanga imbuto, gutera 50-100 mg/kg by'amazi iyo ingemwe zifite amababi 2-6 nyayo bishobora guhindura inkeri y'inkeri ikaba iy'inyange, bigatuma imbuto zikura neza, kandi bikongera umusaruro w'imbuto.
(6) Guteza imbere gukuramo ibiti no kurabya indabyo, kunoza ingano y'ubwoko bwiza bwo kororoka
Gibberellin ishobora gutuma imboga zitangira kurabya vuba umunsi muremure. Gutera ibimera cyangwa gutonyanga uduce duto tw’ibyiza bya gibberellin 50-500mg/kg bishobora kuvamo karoti, amashu, radish, seleri, amashu y’Abashinwa n’ibindi bihingwa bikura ku zuba rya 2a. Gutera ibimera mu gihe cy’umunsi muto.
(7) Kugabanya uburozi bw'ibinyabuzima buterwa n'indi misemburo
Nyuma yo gukomeretsa imboga, kuvurwa hakoreshejwe umuti wa 2.5-5 mg/kg byashoboraga kugabanya uburozi bwa paclobutrazol na chlormethalin; kuvurwa hakoreshejwe umuti wa 2 mg/kg byashoboraga kugabanya uburozi bwa ethylene. Inyanya ni mbi bitewe no gukoresha cyane ikintu kirwanya kugwa, gishobora kugabanukaho 20 mg/kg ya gibberellin.

3. Ibintu bikeneye kwitabwaho
Icyitonderwa mu gushyira mu bikorwa:
1️⃣Kurikiza neza imiti ya tekiniki, kandi ni ngombwa kumenya igihe cyiza cyo kuyikoresha, urugero rwayo, aho ikoreshwa, inshuro ikoreshwa, nibindi;
2️⃣Uhujwe n'imiterere y'inyuma, bitewe n'urumuri, ubushyuhe, ubushuhe, ibintu by'ubutaka, ndetse n'ibipimo by'ubuhinzi nk'ubwoko butandukanye, ifumbire, ubucucike, n'ibindi, umuti uzagira ingaruka zitandukanye. Ikoreshwa ry'ibipimo by'imikurire rigomba guhuzwa n'ibipimo bisanzwe by'ubuhinzi;
3️⃣Ntugakoreshe nabi amabwiriza agenga imikurire y'ibimera. Buri tegeko rigenga imikurire y'ibimera rifite ihame ryaryo ry'imikorere, kandi buri muti ufite aho ugarukira. Ntugatekereze ko ubwoko bwose bw'umuti bukoreshwa, buzongera umusaruro kandi bukongera imikorere;
4️⃣Ntukavange n'ibintu bifite alkaline, gibberellin yoroshye kuyihindura no kuyinaniza iyo hari alkaline. Ariko ishobora kuvangwa n'ifumbire mvaruganda idafite aside n'iy'imiti yica udukoko, ikavangwa na urea kugira ngo wongere umusaruro mwiza;
