Yiziphi izilawuli zokukhula kwezitshalo ezingakhuthaza ukumiswa kwezithelo noma ukunciphisa izimbali nezithelo?

1-Naphthyl Acetic Acidingashukumisa ukuhlukana kwamaseli kanye nokwehlukana kwezicubu, yandise ukumiswa kwezithelo, ivimbele ukwehla kwezithelo, futhi yandise isivuno.
Ngesikhathi sokuqhakaza kukatamatisi, fafaza izimbali ngesisombululo samanzi se-1-Naphthyl Acetic Acid ekuhlanganiseni okusebenzayo kuka-10-12.5 mg/kg;
Fafaza ngokulinganayo sonke isitshalo ngaphambi kokuqhakaza kukakotini nangesikhathi sokusetha ibholi, okungadlala indima enhle ekulondolozweni kwezithelo namabholi.

I-Gibberellic Acid (GA3)isheshisa ukukhula kwamangqamuzana ubude, ikhuthaza ukukhula kwe-parthenocarpy nezithelo, futhi ifafaze amagilebhisi ngaphambi nangemva kokuqhakaza, okunomthelela omuhle ekunciphiseni ukuchithwa kwezimbali zamagilebhisi nezithelo;
Ngesikhathi sokuqhakaza ukotini, ukufutha, ukumbozwa kwamabala noma ukufafaza ngokulinganayo i-Gibberellic Acid (GA3) ekuhlanganiseni okuphumelelayo kuka-10-20 mg/kg nakho kungadlala indima ekulondolozweni kwebholi kakotini.

I-Forchlorfenuron (CPPU / KT-30)inomsebenzi we-cytokinin. Uma isetshenziswa kumakhabe nezithelo, ingakhuthaza ukuhlukaniswa kwezimbali, igcine izimbali nezithelo, ikhulise izinga lokumiswa kwezithelo, futhi ikhuthaze ukukhula kwezithelo.
Ngesikhathi sokuqhakaza kwamakhukhamba, sebenzisa i-Forchlorfenuron (CPPU / KT-30) ene-concentration esebenzayo ye-5-15 mg/kg ukucwilisa imibungu ye-melon;
Ngosuku lokuqhakaza kwekhabe noma ngayizolo, sebenzisa i-Forchlorfenuron (CPPU / KT-30) ene-concentration esebenzayo ye-10-20 mg/kg ukucwilisa imibungu ye-melon;
Ngosuku lokuqhakaza kwekhabe noma ngayizolo, sebenzisa i-Forchlorfenuron (CPPU / KT-30) ene-concentration esebenzayo engu-7.5-10 mg/kg ukuze uyifake esiqwini sesithelo, esinomphumela wokulondoloza izithelo.

I-Thidiazuron (TDZ)ingakhuthaza ukuhlukana kwamaseli, ikhulise inani lamaseli, futhi ikhulise isithelo.
Ngemuva kokuqhakaza kwamakhukhamba, sebenzisa ukugxila okusebenzayo kwe-4-5 mg/kg ukucwilisa imibungu ye-melon;
Ngosuku lokuqhakaza kwekhabe noma ngayizolo, sebenzisa i-Thidiazuron ene-concentration esebenzayo engu-4-6 mg/kg ukufafaza amanzi ngokulinganayo ukuze uthuthukise izinga lokumiswa kwezithelo.

I-Sodium Nitrophenolates (Atonik)iyisilawuli sokukhula kwesitshalo esigcina izithelo esingakhuthaza ukugeleza kwe-protoplasm yeseli, sithuthukise ubungqabavu bengqamuzana, sisheshise ukukhula nokuthuthuka kwezitshalo, sithuthukise ukumelana nokucindezeleka, futhi sikhuthaze ukuqhakaza futhi sivimbele ukuwa kwezimbali nezithelo. Isibonelo, ngesikhathi sokuhluma, ukuhluma, kanye nezigaba zokubeka izithelo zikatamatisi, sebenzisa i-Sodium Nitrophenolates (Atonik) ekuhlanganiseni okuphumelelayo kuka-6 kuya ku-9 mg/kg ukufutha ngokulinganayo eziqwini nasemaqabungeni ngamanzi. Kusukela esigabeni sokuqala sokuqhakaza kwamakhukhamba, fafaza i-Sodium Nitrophenolates (Atonik) ekuhlanganiseni okusebenzayo kuka-2 kuya ku-2.8 mg/kg njalo ezinsukwini ezingu-7 kuya kweziyi-10 ngezifutho ezi-3 ezilandelanayo, okunomphumela wokulondoloza izithelo nokwandisa isivuno. I-Triacontanol ingathuthukisa umsebenzi we-enzyme, amandla e-photosynthetic, futhi ikhuthaze ukumuncwa kwezitshalo kwezakhi zamaminerali, ezingakhuthaza ukuvuthwa kwangaphambi kwesikhathi futhi zilondoloze izimbali nezithelo. Phakathi nesigaba sokuqhakaza sikakotini kanye nesonto lesi-2 kuya kwelesi-3 ngemva kwalokho, ukufafaza amaqabunga nge-Triacontanol ekuhlanganiseni okuphumelelayo kuka-0.5 kuya ku-0.8 mg/kg kunomphumela wokulondoloza amabhola kanye nokwandisa isivuno.

Eminye imikhiqizo exubile nayo inomphumela wokulondoloza izimbali nezithelo.Njenge-Indole Acetic Acid (IAA), Brassinolide (BRs), njll.,ingenza kusebenze amangqamuzana ezitshalo, ikhuthaze ukuhlukana kwamangqamuzana nokukhula, futhi yandise okuqukethwe kwe-chlorophyll namaprotheni. Ngemva kokufafaza, kungakhuthaza ukukhula nokuba luhlaza kwamaqabunga esihlahla sezithelo, kulondoloze izimbali nezithelo, kukhuphule izinga lokumiswa kwezithelo, futhi ekugcineni kwandise isivuno futhi kuthuthukise izinga. Ekupheleni kokuhluma kwama-apula nangemuva kokuqhakaza, umthamo osebenzayo we-75-105 g/hectare usetshenziselwa ukufafaza amanzi ngokulinganayo ngaphambili nangemuva kwamaqabunga, okungagcina kakhulu izithelo futhi kwandise isivuno.

I-Naphthaleneacetic acidkungaphazamisa imetabolism kanye nokuthuthwa kwamahomoni ezitshalweni, ngaleyo ndlela kukhuthaze ukwakheka kwe-ethylene. Inomphumela wokuzaca kwezimbali nezithelo uma isetshenziswa ku-apula, ipheya, i-tangerine, nezihlahla ze-persimmon; I-6-benzylaminopurine, i-ethephon, njll nayo ibe nomthelela wokunciphisa izimbali nezithelo.
Uma usebenzisa izilawuli zokukhula kwezitshalo ezibalulwe ngenhla, kuyadingeka ukulawula ngokuqinile isikhathi sokufaka isicelo, ukugxilisa ingqondo, nokukhetha izitshalo nezinhlobonhlobo ezifanele.
