Muhupenyu hwezuva nezuva, ethephon inowanzoshandiswa kuibva mabhanana, matomatisi, persimmons nemimwe michero, asi ndeapi chaiwo mabasa ethephon?Nzira yekuishandisa sei zvakanaka?
Ethephon, yakafanana ne ethylene, inonyanya kuwedzera kukwanisa kwe ribonucleic acid synthesis mumasero uye inosimudzira mapuroteni synthesis.Munzvimbo yekubira yezvirimwa, senge petioles, mashanga emichero, uye hwaro hwemapetali, nekuda kwekuwedzera kweprotein synthesis, iyo resynthesis ye cellulase mu abscission layer inosimudzirwa, uye kuumbwa kweabscission layer inokwidziridzwa. , zvichiguma nokudeuka kwenhengo.
Ethephon inogona kuwedzera basa rema enzymes, uye inogonawo kuita phosphatase nemamwe ma enzymes ane chekuita nekuibva kwemichero kana muchero waibva kukurudzira kuibva.Ethephon ndeyepamusoro-mhando uye yepamusoro-soro yekukura kwechirimwa.Morekuru ye ethephon inogona kuburitsa molecule ye ethylene, ine mhedzisiro yekusimudzira kuibva kwemichero, kukurudzira kuyerera kwemaronda, uye kudzora shanduko yechikadzi.
Kushandiswa kukuru kwe ethephon kunosanganisira: kukurudzira kusiyaniswa kwemaruva echikadzi, kukurudzira kuibva kwemichero, kukurudzira kukura kwechirimwa, uye kuputsa dormancy yechirimwa.
Maitiro ekushandisa ethephon nemhedzisiro yakanaka?
1. Inoshandiswa kuibva donje:
Kana donje rine simba rakakwana, peach yevhuvhu inowanzoibva ne ethephon.Kushandiswa kwe ethephon kukotoni kunoda kuti mabhoti akawanda ekotoni mumunda wekotoni ane zera remazuva anopfuura 45, uye tembiricha yezuva nezuva inofanira kunge iri pamusoro pemadhigirii makumi maviri paunoshandisa ethephon.
Pakuibva kwedonje, 40% ethephon inonyanya kushandiswa kuderedza 300 ~ 500 nguva dzemvura, uye kupfapfaidza mangwanani kana tembiricha yakakwira.Kazhinji, mushure mekushandiswa kwe ethephon kukotoni, inogona kukurumidza kuputika kwekotoni mabhoro, kuderedza kutumbuka mushure mechando, kunyatsovandudza kunaka kwekotoni, uye nokudaro kuwedzera goho rekotoni.
2. Inoshandiswa pakudonha kwejujube, hawthorn, olive, ginkgo nemimwe michero:
Jujube: Kubva pakuibva kwachena kusvika pakuibva kwejujube, kana kuti mazuva manomwe kusvika masere tisati takohwewa, itsika yokupfapfaidza ethephon.Kana ikashandiswa kugadzira misi ye candied, nguva yekupfapfaidza inogona kufambiswa zvakanaka, uye yakapfapfaidzwa ethephon concentration i0.0002%.~ 0.0003% yakanaka.Nekuti ganda rejuju rakatetepa kwazvo, kana chiri chikafu chakabikwa chakasiyana, hazvina kukodzera kushandisa ethephon kudonha.
Hawthorn: Kazhinji, 0.0005% ~ 0.0008% concentration ethephon solution inopfapfaidzwa 7 ~ 10 mazuva asati asvika kukohwa kwehawthorn.
Maorivhi: Kazhinji, 0.0003% ethephon solution inopfapfaidzwa kana maorivhi ava pedyo nekukura.
Michero iri pamusoro inogona kudonha mushure memazuva matatu kusvika mana mushure mekupfapfaidza, zunza matavi makuru.
3. Zvekuibva kwemadomasi:
Kazhinji, kune nzira mbiri dzekuibva madomasi ne ethephon.Imwe ndeyekunyorovesa muchero mushure mekukohwa.Kune madomasi akakura asi asati akura mu "ruvara-kuchinja nguva", aise mumhinduro ye ethephon ine 0.001% ~ 0.002%., uye mushure memazuva mashomanana ekugadzirisa, tomate inoshanduka tsvuku uye yakakura.
Chechipiri ndechekupenda muchero pamuti wemadomasi.Isa 0.002% ~ 0.004% ethephon solution pamuchero wedomasi mu "ruvara-kuchinja nguva".Madomasi akaibva nenzira iyi akafanana nemuchero wakangoibva.
4. Kuti cucumber ikwezve maruva:
Kazhinji, kana madzinde emagaka ane 1 kusvika ku3 mashizha echokwadi, mhinduro ye ethephon ine mutsara we 0.0001% kusvika 0.0002% inopfapfaidzwa.Kazhinji, inoshandiswa kamwe chete.
Kushandiswa kwe ethephon muchikamu chekutanga chekusiyanisa maruva emagaka kunogona kuchinja tsika yemaruva, kukonzera kuitika kwemaruva echikadzi uye maruva mashoma echirume, nokudaro kuwedzera nhamba yemavise uye nhamba yemavise.
5. Pakuibva kwebhanana:
Kuibva mabhanana ne ethephon, 0.0005% ~ 0.001% concentration ye ethephon solution inowanzoshandiswa kuisa pamuviri kana kumwaya mabhanana manomwe kana masere akaibva.Kupisa kunodiwa pamadhigirii makumi maviri.Mabhanana anobatwa ne ethephon anogona kukurumidza kunyorova uye kushanduka yero, iyo astringency inonyangarika, starch inoderera, uye shuga inowedzera.
