Bophelong ba letsatsi le leng le le leng, ethephon e atisa ho sebelisoa ho butsoa libanana, tamati, persimmons le litholoana tse ling, empa mesebetsi e khethehileng ea ethephon ke efe?Joang ho e sebelisa hantle?
Ethephon, e tšoanang le ethylene, haholo-holo e ntlafatsa bokhoni ba ribonucleic acid synthesis liseleng le ho khothalletsa protheine synthesis.Sebakeng sa abscission sa limela, joalo ka li-petioles, mahlaka a litholoana, le motheo oa mahlaku, ka lebaka la keketseho ea protheine synthesis, resynthesis ea cellulase ka har'a lesela la abscission e ea khothaletsoa, 'me sebopeho sa sekhahla sa abscission se potlakisoa. , ho fella ka ho tsoa ha litho tsa 'mele.
Ethephon e ka ntlafatsa mosebetsi oa li-enzyme, hape e ka kenya phosphatase le li-enzyme tse ling tse amanang le ho butsoa ha litholoana ha litholoana li butsoitse ho khothalletsa ho butsoa ha litholoana.Ethephon ke taolo ea kholo ea limela ea boleng bo holimo le e sebetsang hantle.Molek'hule ea ethephon e ka lokolla molek'hule ea ethylene, e nang le liphello tsa ho khothalletsa ho butsoa ha litholoana, ho susumetsa phallo ea maqeba, le ho laola phetoho ea tekano.
Tšebeliso ea mantlha ea ethephon e kenyelletsa: ho khothaletsa phapang ea lipalesa tse tšehali, ho khothaletsa ho butsoa ha litholoana, ho etsa hore limela li fokotsehe, le ho roba borokho ba limela.
Mokhoa oa ho sebelisa ethephon ka phello e ntle?
1. E sebelisoa ho butsosa k'hothone:
Haeba k'hothone e na le matla a lekaneng, perekisi ea hoetla e atisa ho butsoa ka ethephon.Ho sebelisoa ha ethephon ho k'hothone ho hloka hore boholo ba libotlolo tsa k'hothone tšimong ea k'hothone li be le lilemo tse fetang matsatsi a 45, 'me mocheso oa letsatsi le letsatsi o lokela ho ba ka holimo ho likhato tse 20 ha o sebelisa ethephon.
Bakeng sa ho butsoa ha k'hothone, 40% ethephon e sebelisoa haholo-holo ho hlapolla makhetlo a 300 ~ 500 a metsi, ebe o e fafatsa hoseng kapa ha mocheso o le holimo.Ka kakaretso, ka mor'a ho sebelisoa ha ethephon ho k'hothone, e ka potlakisa ho phunyeha ha libotlolo tsa k'hothone, ho fokotsa ho thunya ka mor'a serame, ho ntlafatsa boleng ba k'hothone ka katleho, kahoo ho eketsa chai ea k'hothone.
2. E sebelisetsoa hoetla ha jujube, hawthorn, mohloaare, ginkgo le litholoana tse ling:
Jujube: Ho tloha boemong ba ho butsoa ha bosoeu ho isa boemong ba ho butsoa ha jujube, kapa matsatsi a 7 ho isa ho a 8 pele ho kotuloa, ho tloaelehile ho fafatsa ethephon.Haeba e sebelisetsoa ho sebetsana le matsatsi a candied, nako ea ho fafatsa e ka ba e tsoetseng pele hantle, 'me mahloriso a ethephon a fafalitsoeng ke 0.0002%.~ 0.0003% e ntle.Hobane lekhapetla la jujube le tšesaane haholo, haeba e le mofuta oa lijo tse tala, ha hoa lokela ho sebelisa ethephon ho e theola.
Hawthorn: Ka kakaretso, 0.0005% ~ 0.0008% tharollo ea ethephon ea mahloriso e fafatsoa matsatsi a 7 ~ 10 pele ho kotulo e tloaelehileng ea hawthorn.
Mehloaare: Ka kakaretso, tharollo ea ethephon ea 0.0003% e fafatsoa ha mohloaare o le haufi le ho hōla.
Litholoana tse 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 mekhoa e 'meli ea ho butsoa tamati ka ethephon.E 'ngoe ke ho inela litholoana ka mor'a kotulo.Bakeng sa tamati e seng e hōlile empa e e-s'o hōle "nakong ea ho fetola mebala", li kenye ka har'a tharollo ea ethephon ka motsoako oa 0.001% ~ 0.002%., 'me ka mor'a matsatsi a seng makae a stacking, tamati e tla fetoha e khubelu' me e hōlile.
Ea bobeli ke ho penta litholoana sefateng sa tamati.Sebelisa 0.002% ~ 0.004% tharollo ea ethephon holim'a tholoana ea tamati "nakong ea ho fetola mebala".Tamati e butsoitseng ka mokhoa ona e tšoana le tholoana e butsoitseng ka tlhaho.
4. Hore likomkomere li hohele lipalesa:
Ka kakaretso, ha lipeo tsa likomkomere li na le makhasi a 'nete a 1 ho isa ho a 3, tharollo ea ethephon e nang le motsoako oa 0.0001% ho ea ho 0.0002% e fafatsoa.Ka kakaretso, e sebelisoa hang feela.
Tšebeliso ea ethephon qalong ea phapang ea lipalesa tsa likomkomere e ka fetola mokhoa oa lipalesa, ea etsa hore ho be le lipalesa tse tšehali le lipalesa tse fokolang tsa banna, kahoo li eketsa palo ea mahapu le palo ea mahapu.
5. Bakeng sa ho butsoa ha banana:
Ho butsosa libanana ka ethephon, 0.0005% ~ 0.001% concentration ea ethephon solution hangata e sebelisoa ho emisa kapa ho fafatsa libanana tse supileng kapa tse robeli tse butsoitseng.Ho futhumatsa ho hlokahala ka likhato tse 20.Libanana tse tšoaroang ka ethephon li ka nolofatsa ka potlako 'me tsa fetoha mosehla, li-astringency lia nyamela, starch e fokotseha,' me tsoekere e eketseha.
