Ukukhuthaza ukuvuthwa kweziqhamo kwangoko kunye nokunyusa ukuqokelelwa kwezinto ezomileyo ezi ndidi zilandelayo zokulawula ukukhula kwezityalo zingakhethwa.

1. I-Ethephon

Umsebenzi:Ikhupha i-ethylene, ikhuthaza ngokuthe ngqo ukuvuthwa kweziqhamo, ukukhula kombala, kunye nokuthamba, ngaloo ndlela inciphisa kakhulu ixesha lokuvuthwa. Ngaxeshanye, iphucula ukuhanjiswa kweemveliso zephotosynthetic kwisiqhamo, ngokungathanga ngqo inyusa ukuqokelelwa kwento eyomileyo.

Izityalo ezisebenzayo: Iziqhamo zeClimacteric ezifana neebhanana, iitumato, iicitrus, iimango, iiloquats, njl.
Ugxininiso lwesicelo:** Isetyenziswa njengesisombululo se-0.1% -0.3% ngokutshizwa kweziqhamo okanye ukudipha; kufuneka kuthathelwe ingqalelo ukuphepha i-phytotoxicity (umzekelo, ukuhla kweziqhamo okanye ukugquma okubangelwa kugxininiso olugqithiseleyo).


2. I-Triacontanol

Umsebenzi: Yandisa ifotosynthesis, yonyusa umxholo wechlorophyll, kwaye yongeza umsebenzi we-amylase, ngaloo ndlela ikhuthaza ukuqokelelwa kwezinto ezomileyo kwaye ikhuthaza ukukhula kwezityalo kwangaphambili.
Indlela yesicelo: I-Foliar spray kwi-concentration ye-0.5 ppm (oko kukuthi, 0.5 mg / L). Ukuze ufumane iziphumo ezigqwesileyo, galela kube kanye ngexesha lenqanaba lokuqala lokuntshula kweentyatyambo kwaye kube kanye ngexesha lokudumba okupheleleyo.

3. I-Diethyl aminoethyl hexanoate (DA-6)

Umsebenzi: Yandisa amazinga e-photosynthetic, iphucula i-carbon kunye ne-nitrogen metabolism, kunye nokulibaziseka kwe-senescence; ikhuthaza ukuvuthwa kwangoko, ukwanda kwesivuno, kunye nokuphucula umgangatho. Ikulungele ukusetyenziswa kuwo wonke umjikelo wokukhula kwaye ihlala isebenza phantsi kweemeko zobushushu obuphantsi.
Ugxininiso olucetyiswayo: 10–20 mg/L; sebenzisa ngokutshiza amaxesha angama-2-3 ngexesha leziqhamo ezincinci kunye nenqanaba lokwandiswa kweziqhamo.

4. Brassinolide

Umsebenzi: Ukhuthaza ukwanda kweeseli kunye nokwahlulahlula, ukonyusa izinga lokumisela iziqhamo kunye nobunzima besiqhamo somntu ngamnye, kwaye kuphuculwe ukufana kweziqhamo nokuba nombala; ikhawulezisa ukukhula ngama-25%–40%.
Ixesha lokufaka isicelo: Faka ngokutshiza ngexesha lokuqala lokuntshula kweentyatyambo, iziqhamo ezitsha, kunye nenqanaba lokwandiswa kweziqhamo.


5. I-Forchlorfenuron (KT-30, CPPU)

Umsebenzi: Nangona isaziwa kakhulu ngokukhuthaza ukwandiswa kweziqhamo kunye nokugcina iintyatyambo neziqhamo, inokuxhasa ngokungathanga ngqo ukuvuthwa kwangethuba kunye nokuphuculwa komgangatho ngokuvuselela ukwahlukana kweeseli kunye nokuyalela ukwabiwa kwezinto ezomileyo. (Qaphela: Ukusetyenziswa okugqithisileyo kunokulibazisa uphuhliso lombala.)
