Bophelong ba letsatsi le letsatsi, ethephon hangata e sebediswa ho butswa dibanana, ditamati, di-persimmons le ditholwana tse ding, empa mesebetsi e ikgethang ya ethephon ke efe? O ka e sebedisa jwang hantle?
Ethephon, e tšoanang le ethylene, haholo-holo e ntlafatsa bokhoni ba ho kopanya ribonucleic acid liseleng 'me e khothalletsa ho kopanya protheine. Sebakeng sa ho arohana ha limela, tse kang li-petioles, likutu tsa litholoana, le botlaaseng ba mahlaku a limela, ka lebaka la keketseho ea ho kopanya protheine, ho etsoa hape ha cellulase lera la ho arohana ha lisele hoa khothaletsoa, 'me ho thehoa ha lera la ho arohana ha lisele hoa potlakisoa, e leng se fellang ka ho tšoloha ha litho.
Ethephon e ka ntlafatsa ts'ebetso ea li-enzyme, 'me e ka boela ea kenya tšebetsong phosphatase le li-enzyme tse ling tse amanang le ho butsoa ha litholoana ha litholoana li butsoitse ho khothaletsa ho butsoa ha litholoana. Ethephon ke molaoli oa kholo ea limela oa boleng bo holimo le o sebetsang hantle. Molek'hule ea ethephon e ka lokolla molek'hule ea ethylene, e nang le litlamorao tsa ho khothaletsa ho butsoa ha litholoana, ho susumetsa phallo ea maqeba, le ho laola phetoho ea bong.
Tšebeliso e ka sehloohong ea ethephon e kenyelletsa: ho khothaletsa phapang ea lipalesa tse tšehali, ho khothalletsa ho butsoa ha litholoana, ho khothalletsa ho ba kgutshwanyane ha limela, le ho sitisa ho khutsa ha limela.
Mokhoa oa ho sebelisa ethephon ka katleho e ntle?
1. E sebelisetsoa ho butsoisa k'hothone:
Haeba k'hothone e na le matla a lekaneng, perekisi ea hoetla hangata e butsoa ka ethephon. Ho sebelisoa ha ethephon k'hothoneng ho hloka hore boholo ba libolo tsa k'hothone tšimong ea k'hothone li be le lilemo tse fetang 45, 'me mocheso oa letsatsi le letsatsi o lokela ho ba kaholimo ho likhato tse 20 ha ho sebelisoa ethephon.
Bakeng sa ho butsoa ha k'hothone, 40% ea ethephon e sebelisoa haholo ho nolofatsa metsi ka makhetlo a 300 ~ 500, le ho e fafatsa hoseng kapa ha mocheso o le holimo. Ka kakaretso, kamora ho sebelisa ethephon k'hothoneng, e ka potlakisa ho petsoha ha libolo tsa k'hothone, ea fokotsa ho thunya ha serame, ea ntlafatsa boleng ba k'hothone ka katleho, 'me kahoo ea eketsa chai ea k'hothone.
2. E sebelisetsoa hoetla ha jujube, hawthorn, mohloaare, ginkgo le litholoana tse ling:
Jujube: Ho tloha mohatong oa ho butsoa ha jujube e tšoeu ho isa mohatong oa ho butsoa ha jujube e hlabang, kapa matsatsi a 7 ho isa ho a 8 pele ho kotulo, ho tloaelehile ho fafatsa ethephon. Haeba e sebelisoa bakeng sa ho sebetsana le matsatsi a monate, nako ea ho fafatsa e ka ntlafatsoa ka nepo, 'me khatello ea ethephon e fafalitsoeng ke 0.0002%. ~0.0003% e ntle. Hobane lekhapetla la jujube le lesesaane haholo, haeba e le mofuta oa lijo tse tala, ha hoa lokela ho sebelisa ethephon ho e lahla.
Hawthorn: Ka kakaretso, tharollo ea ethephon ea 0.0005% ~ 0.0008% e fafatsoa matsatsi a 7 ~ 10 pele ho kotulo e tloaelehileng ea hawthorn.
Mehlwaare: Ka kakaretso, tharollo ea ethephon ea 0.0003% e fafatsoa ha mehlwaare e se e le haufi le ho butsoa.
Litholoana tse boletsoeng ka holimo li ka oa ka mor'a matsatsi a 3 ho isa ho a 4 ka mor'a ho fafatsa, sisinya makala a maholo.
3. Bakeng sa ho butsoa ha tamati:
Ka kakaretso, ho na le litsela tse peli tsa ho butsoisa tamati ka ethephon. E 'ngoe ke ho inela litholoana ka mor'a kotulo. Bakeng sa tamati tse holileng empa li e-so hole nakong ea "nako ea ho fetola 'mala", li kenye ka har'a tharollo ea ethephon ka khatello ea 0.001% ~ 0.002%., 'me ka mor'a matsatsi a' maloa a ho bokellana, tamati e tla ba khubelu 'me e butsoe.
Ea bobeli ke ho penta litholoana sefateng sa tamati. Tšela tharollo ea ethephon ea 0.002% ~ 0.004% holim'a litholoana tsa tamati nakong ea "nako ea ho fetola 'mala". Tamati e butsoitsoeng ka mokhoa ona e tšoana le litholoana tse butsoitseng ka tlhaho.
4. Bakeng sa khukhamba ho hohela lipalesa:
Ka kakaretso, ha dipeo tsa khukhampa di na le mahlaku a nnete a 1 ho isa ho a 3, tharollo ya ethephon e nang le mahloriso a 0.0001% ho isa ho 0.0002% e a fafatswa. Ka kakaretso, e sebediswa hanngwe feela.
Tšebeliso ea ethephon mohatong oa pele oa ho khetholla lithunthung tsa likomkomere ka lipalesa ho ka fetola mokhoa oa ho thunya, ho baka ho hlaha ha lipalesa tse tšehali le lipalesa tse nyane tsa banna, ka hona ho eketsa palo ea mahapu le palo ea mahapu.
5. Bakeng sa ho butsoa ha banana:
Ho butsoisa libanana ka ethephon, tharollo ea ethephon ea 0.0005% ~ 0.001% hangata e sebelisoa ho noesa kapa ho fafatsa libanana tse supileng kapa tse robeli tse butsoitseng. Ho hlokahala ho futhumatsa likhato tse 20. Libanana tse phekotsoeng ka ethephon li ka nolofala kapele 'me tsa fetoha mosehla, astringency ea nyamela, starch ea fokotseha, 'me tsoekere ea eketseha.
