Iwo 7 mabasa makuru egibberellin uye 4 makuru ekudzivirira, varimi vanofanira kunzwisisa pachine nguva vasati vashandisa

Gibberellinihomoni yechirimwa inowanikwa zvakanyanya muumambo hwechirimwa uye inobatanidzwa mune zvakawanda zvipenyu zvipenyu zvakadai sekukura kwechirimwa uye kukura.Gibberellins anonzi A1 (GA1) kuA126 (GA126) maererano nehurongwa hwekuwanikwa.Iine mabasa ekusimudzira kumera kwembeu uye kukura kwezvirimwa, kutanga maruva nekubereka michero, nezvimwewo, uye inoshandiswa zvakanyanya muzvirimwa zvekudya zvakasiyana.

1. Physiological basa
Gibberellinchinhu chine simba zvikuru uye chakajairika chirimwa chinosimudzira zvinhu.Inogona kukurudzira kurebesa masero ezvirimwa, kurebesa dzinde, kuwedzera mashizha, kukurumidza kukura nekukura, kuita kuti zvirimwa zvikure kare, uye kuwedzera goho kana kuvandudza kunaka;inogona kuputsa dormancy, kukurudzira kumera;Muchero wembeu;inogonawo kushandura bonde uye reshiyo yezvimwe zvirimwa, uye kuita kuti zvimwe zvirimwa zviviri zvinotumbuka mugore razvino.

2. Kushandiswa kwegibberellin mukugadzirwa
(1) Kurudzira kukura, kukurumidza kukura uye kuwedzera goho
Kurapa kwemashizha akawanda emiti yakasvibirira negibberellin kunogona kukurumidza kukura uye kuwedzera goho.Sereri inopfapfaidzwa nemvura inokwana 30~50mg/kg panosvika hafu yemwedzi mushure mekukohwa, goho rinowedzerwa nezvikamu zvinopfuura 25%, madzinde nemashizha zvinova hypertrophic, uye misika inoita 5~6d mangwanani.

(2) Bvisa dormancy uye kukurudzira kumera
Mumastrawberry greenhouse anobatsira kurima nekurima semi-facilitative, mushure mekuvhara nekudziya kwemazuva matatu, kureva, kana maruva anodarika 30% aonekwa, pfapfaidza 5 mL ye5 ~ 10 mg/kg gibberellin solution pachirimwa, uchitarisa mwoyo mashizha, izvo zvinogona kuita kuti inflorescence yepamusoro ibude mberi kwenguva., kukurudzira kukura uye kukura kwekutanga.
(3) Kurudzira kukura kwezvibereko
Miriwo yemavise inofanira kupfapfaidzwa ne 2 ~ 3mg/kg yemvura pamichero midiki kamwe padiki padanho remavise, izvo zvinogona kukurudzira kukura kwemavise madiki, asi usapfapfaidza mashizha kudzivirira kuwedzera kwenhamba yemaruva echirume.
(4) Wedzera nguva yekuchengetedza
Kumwaya michero yemavise ne2.5 ~ 3.5mg/kg mvura isati yakohwewa inogona kurebesa nguva yekuchengeta.Kupfapfaidza muchero ne50 ~ 60mg/kg mvura yebhanana isati yakohwewa kune imwe mhedzisiro yekurebesa nguva yekuchengetedza michero.Jujube, longan uye mamwe magibberellins anogonawo kunonoka kukwegura uye kuwedzera nguva yekuchengetedza.
(5) Shandura chiyero chemaruva echirume neechikadzi kuti mbeu iwedzere goho
Kushandisa cucumber line yemunhukadzi pakugadzira mbeu, kumwaya 50-100 mg/kg yemvura kana madzinde ave nemashizha echokwadi 2-6 anogona kusandura cucumber remukadzi kuita hermaphrodite, kusvina nekukurisa, uye kuwedzera goho rembeu.
(6) Kurudzira kutorwa kwedzinde uye kutumbuka, kuvandudza kuberekana kwemhando dzemhando dzepamusoro
Gibberellin inogona kukurudzira kutanga maruva kwemiriwo yemazuva mazhinji.Kupfapfaidza zvirimwa kana kudonha mapeji ekukura ne50 ~ 500mg/kg yegibberellin kunogona kugadzira makarotsi, makabheji, radishes, celery, Chinese cabbage uye zvimwe 2a-kukura zvirimwa zvezuva.Bolting pasi pemazuva mapfupi mamiriro.
(7) Bvisa phytotoxicity inokonzerwa nemamwe mahomoni
Mushure mokunge mishonga yemiriwo yakakuvadzwa, kurapwa ne 2.5-5 mg / kg mhinduro inogona kubvisa phytotoxicity ye paclobutrazol uye chlormethalin;kurapwa ne 2 mg/kg mhinduro inogona kuderedza phytotoxicity ye ethylene.Tomato inokuvadza nekuda kwekushandisa zvakanyanya anti-falling element, iyo inogona kudzikiswa ne20mg/kg gibberellin.

3. Nyaya dzinoda kutarisirwa
Cherechedza mukushandiswa kunoshanda:
1️⃣Kunyatso tevera mushonga wehunyanzvi, uye zvinodikanwa kuti uone nguva yakakwana, kutarisisa, nzvimbo yekushandisa, frequency, nezvimwe zvemushonga;
2️⃣Yakabatanidzwa nemamiriro ekunze, nekuda kwechiedza, tembiricha, humidity, ivhu zvinhu, pamwe neagronomic matanho akadai akasiyana, fetiraiza, density, nezvimwewo, mushonga unenge uine madhigirii akasiyana.Kushandiswa kwezvigadziriso zvekukura kunofanirwa kusanganiswa nemaitiro akajairika agronomic zviyero;
3️⃣Usashungurudza zvinomera zvinokura.Imwe neimwe chirimwa kukura regulator ine yayo biological musimboti chiito, uye mumwe mushonga ane zvimwe zvausingakwanisi.Usafunga kuti chero rudzi rwemishonga inoshandiswa, ichawedzera kugadzirwa uye kuwedzera kushanda;
4️⃣Usasanganise nealkaline zvinhu, gibberellin iri nyore kuita neutralize uye kukundikana pamberi pealkali.Asi inogona kusanganiswa nemafetireza ane acidic uye asina kwayakarerekera nemishonga yezvipembenene, uye yakasanganiswa neurea kuti iwedzere goho zviri nani;
