Muhupenyu hwezuva nezuva, ethephon inowanzoshandiswa kuibva mabhanana, madomasi, persimmons nemimwe michero, asi ndeapi mabasa chaiwo eethephon? Ungaishandisa sei zvakanaka?
Ethephon, yakafanana ne ethylene, inonyanya kuwedzera kugona kwe ribonucleic acid mumasero uye inokurudzira kugadzirwa kweprotein. Munzvimbo yekubuda kwezvirimwa, senge petioles, madzinde emichero, uye hwaro hwemaruva, nekuda kwekuwedzera kwekugadzirwa kweprotein, kugadzirwazve kwe cellulase mu abscission layer kunokurudzirwa, uye kuumbwa kwe abscission layer kunokurumidza, zvichikonzera kubuda kwenhengo.
Ethephon inogona kuwedzera mashandiro ema enzymes, uye inogona zvakare kumutsa phosphatase nemamwe ma enzymes ane chekuita nekuibva kwemichero kana muchero waibva kuti ukurudzire kuibva kwemichero. Ethephon inodzora kukura kwezvirimwa zvemhando yepamusoro uye inoshanda zvakanaka. Morekuru we ethephon anogona kuburitsa molekuru we ethylene, iyo ine mhedzisiro yekukurudzira kuibva kwemichero, kukurudzira kuyerera kwemaronda, uye kudzora kushanduka kwevakadzi.
Mashandisirwo makuru e ethephon anosanganisira: kukurudzira kusiyana kwemaruva echikadzi, kukurudzira kuibva kwemichero, kukurudzira kukura kwemiti, uye kukanganisa kugara kwenguva refu kwemiti.
Nzira yekushandisa sei ethephon nemhedzisiro yakanaka?
1. Donje rinoshandiswa kuibva:
Kana donje riine simba rakakwana, peach yemwaka wechando inowanzoibva ne ethephon. Kuisa ethephon mudonje kunoda kuti madonje mazhinji ari mumunda wedonje ave nemakore anopfuura makumi mana nemashanu, uye tembiricha yezuva nezuva inofanira kunge iri pamusoro pemadhigirii makumi maviri pakushandisa ethephon.
Pakuibva kwedonje, 40% ethephon inonyanya kushandiswa kuderedza mvura ka300 ~ 500, uye kuipfapfaidza mangwanani kana tembiricha yakwira. Kazhinji, mushure mekushandisa ethephon mudonje, inogona kukurumidzisa kutsemuka kwebolls dzedonje, kuderedza kutumbuka mushure mechando, kuvandudza kunaka kwedonje, uye nokudaro kuwedzera goho redonje.
2. Inoshandiswa pakudonha kwejujube, hawthorn, olive, ginkgo nemimwe michero:
Jujube: Kubva padanho rekuibva jena kusvika padanho rekuibva rakapfava rejujube, kana mazuva manomwe kusvika masere usati wakohwa, zvinojairika kupfapfaidza ethephon. Kana ikashandiswa pakugadzira maswiti ane makeke, nguva yekupfapfaidza inogona kuwedzerwa zvakakodzera, uye huwandu hweethephon yakapfapfaidzwa ndeye 0.0002%. ~0.0003% hwakanaka. Nekuti ganda rejujube rakatetepa, kana riri rekudya risingagayiwe, hazvina kukodzera kushandisa ethephon kudonhedza.
Hawthorn: Kazhinji, mushonga we ethephon une huwandu hwe 0.0005% ~ 0.0008% unopfapfaidzwa mazuva 7 ~ 10 usati wakohwewa zvakanaka.
Maorivhi: Kazhinji, mushonga we 0.0003% ethephon unopfapfaidzwa kana maorivhi ava pedyo nekuibva.
Michero iri pamusoro apa inogona kudonha mushure memazuva matatu kusvika mana mushure mekupfapfaidza, zunzai matavi makuru.
3. Pakuibva kwematomatisi:
Kazhinji, kune nzira mbiri dzekuibva kwematomatisi ne ethephon. Imwe ndeyekunyika muchero mushure mekukohwa. Kune matomatisi akakura asi asati akura munguva yekuchinja kwemavara, aise mumushonga we ethephon une huwandu hwe 0.001% ~ 0.002%., uye mushure memazuva mashoma ekuunganidzwa, matomatisi anozotsvuka uye akura.
Chechipiri ndechekupenda muchero pamuti wematomatisi. Isa mushonga we ethephon we 0.002% ~ 0.004% pamuchero wematomatisi panguva yekuchinja kwemavara. Matomatisi anoibva nenzira iyi akafanana nemuchero wakakura.
4. Kuti cucumber ikwezve maruva:
Kazhinji, kana mbesa dzemacucumber dziine mashizha chaiwo 1 kusvika ku3, mushonga we ethephon une huwandu hwe 0.0001% kusvika 0.0002% unopfapfaidzwa. Kazhinji, unoshandiswa kamwe chete.
Kushandiswa kwe ethephon pakutanga kwekusiyana kwemagaka kunogona kuchinja maitiro ekutumbuka kwemaruva, kukonzera kuwanda kwemaruva echikadzi uye maruva echirume mashoma, nokudaro zvichiwedzera huwandu hwemavise nehuwandu hwemavise.
5. Pakuibva kwebhanana:
Kuti mabhanana aibva ne ethephon, mushonga we ethephon we 0.0005% ~ 0.001% unowanzo shandiswa kunyudza kana kupfapfaidza mabhanana manomwe kana masere akaibva. Kupisa kunodiwa pamadhigirii makumi maviri. Mabhanana anorapwa ne ethephon anogona kukurumidza kupfava uye kuita yero, astringency inonyangarika, starch inoderera, uye huwandu hweshuga hunowedzera.
