Imiphumela yokushisa yokushisa ekukhuleni kwezitshalo iyimbamba

Imiphumela yokungaphansi kokushisa kokukhula kwesitshalo yimbambana: Ibanga lokushisa elilinganiselayo lokushisa elincane (imvamisa 8-10 ° C) inyusa ukukhula kwezitshalo futhi ithuthukise ikhwalithi; Kodwa-ke, umehluko wokushisa ngokweqile noma ushintsho olwedlulele lungavimba ukukhula noma ngisho nokulimala. Lo mphumela uvela kubhalansi phakathi kwe-photosynthesis kanye nokuphefumula, futhi kuyahluka ngokuya ngohlobo lwesitshalo kanye nesigaba sokukhula.

Izinzuzo zokulinganisa okulinganiselayo umehluko wokushisa

1. Ikhuthaza ukunqwabelana kwento e-organic:
Amazinga okushisa aphezulu asemini athuthukisa izithombe, ukuhlanganisa izinto eziphilayo eziningi; Amazinga okushisa aphansi ebusuku avimbela ukuphefumula, ukunciphisa ukusetshenziswa futhi ngenxa yalokho kwandisa ukunqwabelana okuphelele, ukukhula okusekela kanye nezimbali.

2. Ithuthukisa ikhwalithi yomkhiqizo:
Ezindaweni ezinemihluko omkhulu wokushisa (njengezifunda zamagilebhisi nezama-apula), izithelo zinokuqukethwe okuphezulu koshukela kanye nezimbali zingumhlobiso owengeziwe. 2,5

Ukulawula Umjikelezo Wokukhula:
Ithinta ukuhluma kwembewu, umehluko wezimbali wezimbali, nokuqhakaza izimbali nezithelo.

Imiphumela emibi yokwehluka kokushisa ngokweqile: lapho umehluko wokushisa weqa ibanga lokubekezelela lesitshalo, kungaholela ekuvikeleni kokukhula noma ukulimala komzimba.

1. Ukukhula okunciphisiwe noma okuqinile:
Amazinga okushisa aphansi kakhulu ebusuku angadala ukuthi izitshalo zingene ezweni le-semi-durmant, okuholela ekubambezelweni kokuthuthukiswa okusha kwe-shoot kanye neziqu zawo.

Ukulimala kwamaselula kanye ne-metabolic:
Ukushintshashintsha kwamazinga okushisa okwedlulele kuphazamisa umsebenzi we-enzyme, kuphazamisa ibhalansi ye-metabolic, kanye nomonakalo wesithwathwa noma ukucindezelwa okuphezulu, okuthinta amanzi nokumunca amanzi kanye nezakhi zomzimba.

2. Ingozi eyandayo:
Izinguquko zokushisa ezingazelelwe zingaholela kalula ezifweni zokukhunta noma ukulimala ngokomzimba, njengokubola kwamaqabunga ngokuzungeza ngaphansi kwezinguquko ezenzeka emndelweni.

Endaweni enokwehluka kokushisa okukhulu, abalawuli bokukhula kwezitshalo abalandelayo bangasetshenziswa ukusiza izitshalo kangcono ukuzivumelanisa nezinguquko zemvelo futhi zithuthukise isivuno sezitshalo nekhwalithi:

Gibberellic acid (GA3):
I-GA3 ingumlawuli wokukhula kwesitshalo esibanzi esikhuthaza isitshalo se-cell cell, kwandisa ukuphakama kwezitshalo nosayizi wamaqabunga. I-GA3 nayo ingaphula i-doorminen yembewu, nezilimo eziyizigaxa nama-rhizomes, ithuthukise ukuhluma kwayo. Ngaphezu kwalokho, i-GA3 ingavusa ukukhula kwezithelo, yandisa isethi yezithelo, noma yakha izithelo ezingenasimo. Ngaphansi kwezimo zokungafani kokushisa okukhulu, i-gibberellic acid ingasiza izitshalo ukwenza izithombe zingcono, kukhulisa isivuno sezilimo.

Paclobutrazol:
I-Paclobutrazol (PP333) iyisitshalo sokukhula kwesitshalo esivimbela ngokuyinhloko ukukhula okusha kokudubula ngokucindezela ukucindezela kwe-gibbellin. Ilawula ukukhula kokudubula, ithuthukisa izimbali, ikhulisa isethi yezithelo, futhi ithuthukise ikhwalithi yezithelo. Ezindaweni ezinokushintshashintsha kwezinga lokushisa, i-paclobutrazol kungalawula ukukhula kwezitshalo, okwenza izitshalo ziqine futhi zithuthukise ukumelana nazo ekucindezelekeni nasezifo.

Brassinolide:
I-Brassinolide (BR) i-regulator yemvelo yokukhula yesitshalo esithuthukisa ukuhlukaniswa kwamaseli nokubumbana, ukuthuthukisa ukumelana kwezitshalo ekucindezelekeni. Kumibandela ekushintshashintsheni kwamazinga okushisa, i-Brassinolide isiza izitshalo kangcono ukuzivumelanisa nezinguquko zemvelo, ngcono isivuno sezitshalo kanye nekhwalithi.
