Gibberellinke hormone ea limela e teng ka ho pharaletseng sebakeng sa limela 'me e ameha lits'ebetsong tse ngata tsa likokoana-hloko tse kang ho hōla ha limela le tsoelo-pele.Gibberellins e bitsoa A1 (GA1) ho ea ho A126 (GA126) ho latela tatellano ea ho sibolloa.E na le mesebetsi ea ho khothaletsa ho mela ha peo le kholo ea limela, lipalesa tsa pele le litholoana, joalo-joalo, 'me e sebelisoa haholo lijalong tse fapaneng tsa lijo.
1. Mosebetsi oa 'mele
Gibberellinke ntho e khothalletsang kholo ea semela ka kakaretso.E ka khothalletsa ho lelefatsa lisele tsa semela, ho lelefatsa kutu, katoloso ea makhasi, ea potlakisa kholo le nts'etsopele, ea etsa hore lijalo li hole kapele, le ho eketsa chai kapa ho ntlafatsa boleng;e ka senya dormancy, ea khothalletsa ho mela;Litholoana tsa peo;e ka boela ea fetola bong le karo-karolelano ea limela tse ling, 'me ea etsa hore limela tse ling tse peli li thunya selemong sa hona joale.
2. Kopo ea gibberellin tlhahiso
(1) Khothaletsa kholo, kholo ea pele le ho eketsa chai
Kalafo ea meroho e mengata e makhasi a matala ka gibberellin e ka potlakisa kholo le ho eketsa chai.Celery e fafatsoa ka mokelikeli oa 30 ~ 50mg/kg hoo e ka bang halofo ea khoeli ka mor'a kotulo, chai e eketseha ka ho feta 25%, stems le makhasi a hypertrophic, 'me 'maraka ke 5~6d hoseng.
(2) Tlosa boroko 'me u khothalletse ho mela
Ka strawberry greenhouse e thusa ho lema le ho lema ka mokhoa o bonolo, ka mor'a ho koahela le ho futhumala matsatsi a 3, ke hore, ha lipalesa tse fetang 30% li hlaha, fafatsa 5 ml ea 5 ~ 10 mg/kg ea tharollo ea gibberellin ka semela ka seng, u shebane le ho feta. makhasi a pelo, a ka etsang hore inflorescence e holimo e thunye pele ho nako., ho khothaletsa kholo le kholo ea pele.
(3) Khothalletsa khōlo ea litholoana
Meroho ea mahapu e lokela ho fafatsoa ka 2 ~ 3mg/kg ea mokelikeli litholoanang tse nyenyane hang ka sethaleng sa mahapu a manyenyane, a ka khothalletsang kholo ea mahapu a manyenyane, empa u se ke ua fafatsa makhasi ho qoba ho eketseha ha palo ea lipalesa tse tona.
(4) Eketsa nako ea polokelo
Ho fafatsa litholoana tsa mahapu ka metsi a 2.5 ~ 3.5mg/kg pele ho kotuloa ho ka lelefatsa nako ea polokelo.Ho fafatsa litholoana ka metsi a 50 ~ 60mg/kg pele panana e kotuloa ho na le phello e itseng ea ho lelefatsa nako ea polokelo ea litholoana.Jujube, longan le li-gibberellin tse ling le tsona li ka lieha ho tsofala le ho lelefatsa nako ea polokelo.
(5) Fetola karo-karolelano ea lipalesa tse tona le tse tšehali ho eketsa chai ea peo
Ho sebelisa mohala oa likomkomere oa basali bakeng sa tlhahiso ea peo, ho fafatsa 50-100 mg/kg ea metsi ha lipeo li na le makhasi a 'nete a 2-6 ho ka fetola cucumber ea basali hore e be hermaphrodite, ho tsamaisa peo e feletseng, le ho eketsa chai ea peo.
(6) Khothaletsa ho ntšoa ha kutu le lipalesa, ho ntlafatsa mofuta oa ho ikatisa oa mefuta e mengata ea maemo a holimo
Gibberellin e ka hlahisa lipalesa tsa pele tsa meroho ea matsatsi a malelele.Ho fafatsa limela kapa ho rotha lintlha tsa kholo ka 50 ~ 500mg / kg ea gibberellin ho ka etsa lihoete, k'habeche, radishes, celery, k'habeche ea Chaena le lijalo tse ling tsa 2a tse hōlang letsatsi.Bolting tlas'a maemo a nako e khutšoanyane.
(7) Fokotsa phytotoxicity e bakoang ke lihomone tse ling
Ka mor'a hore meroho e feteletseng e lematsoe, phekolo e nang le tharollo ea 2.5-5 mg / kg e ka imolla phytotoxicity ea paclobutrazol le chlormethalin;kalafo ka tharollo ea 2 mg/kg e ka imolla phytotoxicity ea ethylene.Tamati e kotsi ka lebaka la tšebeliso e feteletseng ea ntho e thibelang ho oa, e ka imolloang ka 20mg/kg gibberellin.
3. Litaba tse hlokang tlhokomelo
Ela hloko ts'ebetsong e sebetsang:
1️⃣ Latela ka tieo meriana ea tekheniki, 'me hoa hlokahala ho tseba nako e nepahetseng, mahloriso, sebaka sa ts'ebeliso, khafetsa, joalo-joalo.
2️⃣Ho hokahana le maemo a kantle, ka lebaka la khanya, mocheso, mongobo, lintlha tsa mobu, hammoho le mehato ea agronomic joalo ka mefuta e fapaneng, manyolo, letsoalo, joalo-joalo, sethethefatsi se tla ba le tšusumetso e fapaneng.Tšebeliso ea balaoli ba kholo e lokela ho kopanngoa le mehato e tloaelehileng ea agronomic;
3️⃣Se ke oa sebelisa taolo ea kholo ea limela hampe.Molaoli e mong le e mong oa kholo ea semela o na le molao-motheo oa ts'ebetso ea bioloji, 'me moriana ka mong o na le mefokolo e itseng.U se ke ua nahana hore ho sa tsotellehe hore na ho sebelisoa lithethefatsi tsa mofuta ofe, ho tla eketsa tlhahiso le ho eketsa katleho;
4️⃣Se ke oa tsoakana le lintho tsa alkaline, gibberellin e bonolo ho fokotsa le ho hloleha boteng ba alkali.Empa e ka kopanngoa le menontsha e nang le asiti le e sa nke lehlakore le chefo e bolaeang likokoanyana, 'me ea tsoakoa le urea ho eketsa chai hantle;
