Ukuhamba ngaphaya kweNxunguphako yeHormone: Ukwenza ukuba iziLawuli zokuKhula kweZityalo zikhulise iNyaniso yezoLimo

I-Plant Growth Regulators (PGRs) ludidi lweekhompawundi-nokuba zenziwa ngokwekhemikhali okanye zikhutshwe kwimithombo yebhayoloji-ethi ngokwesakhiwo ifane kwaye isebenze ukulinganisa iihomoni zezityalo zendalo. Nangona kunjalo, zinobuchule obukhethekileyo bokulawula ngokuchanekileyo iinkqubo ezibalulekileyo zezityalo—ezifana nokuncothula, ukuntshula, ukuntshula kweentyatyambo, nokuqhama—kumhlaba obanzi. Ngaphambili, ngenxa yesicelo esingafanelekanga okanye ulwazi olulahlekisayo, igama elithi "ihomoni" lalidla ngokubhalwa ngokungafanelekanga njengegama elifanayo nelithi "ityhefu." Namhlanje, nangona kunjalo-xa isetyenziswe kwingqwalasela echanekileyo, ngexesha elifanelekileyo, kunye nokusebenzisa indlela efanelekileyo-aba balawuli basebenza "njengezandisi zemveliso" ezinamandla ezandleni zamafama.


1. IiHormones zeZityalo vs. IziLawuli zokuKhula kweZityalo: Umahluko wegama elinye, umahluko osisiseko

1.1 ◇ IiHormones zeZityalo: "Abathunywa" bangaphakathi
Ezi zizinto ezilandelwayo eziveliswa ngokwemvelo emzimbeni wesityalo-ezifana ne-auxins, gibberellins, kunye ne-abscisic acid. Idityaniswe kwiindawo ezithile, zithuthwa nge-phloem okanye umjelo we-transpiration ukuya kwii-tissue ezijoliswe kuzo, apho zisebenzisa iziphumo zazo zokulawula.

1.2 ◇ IziLawuli zokuKhula kweZityalo: "IiVava zokulawula" zangaphandle
Ezi zixhobo zokwenziwa okanye ezikhutshiweyo ezilinganisa iihomoni zezityalo. Iyakwazi ukusebenzisa i-wide-spectrum, i-high-concentration, kunye nemiphumo yokuqalisa ngokukhawuleza, baphumelele ngokufanelekileyo imida ye-hormone engapheliyo-oko kukuthi, ukunyanzeliswa kwabo ukuthotywa kunye namazinga abo okuthutha okucothayo. Zisebenza kakhulu njenge "central air conditioning system": zilungele ukuvulwa kwaye zilungelelaniswe kwindawo efunekayo nangawuphi na umzuzu.


2. "Isixhobo soMmangaliso" Xa sisetyenziswe ngokuchanekileyo; “Ityhefu” Xa Isetyenziswa Ngokungafanelekanga—Isilumkiso Semiphumo Emibini

2.1 ◇ Ugxininiso oluphantsi: Ukomeleza iSivuno kunye noMgangatho
Ukukhuthaza Ukumiswa Kweziqhamo: Xa iForchlorfenuron itshizwa kwiintyatyambo zetumata ngexesha leentyatyambo, izinga lokuwa kweentyatyambo liyehla nge-40%, kwaye ubunzima besiqhamo ngasinye bunyuka nge-10% -15%.

Ukwandisa i-Dormancy: Indibaniselwano ye-DA-6 kunye ne-Maleic Hydrazide ivumela iigabhu zetapile ukuba zigcinwe kwindawo yobushushu begumbi kangangenyanga eyongezelelweyo ngelixa zigcina izinga lokuntshula elingaphezulu kwe-85%.

Ukuphucula Ukuxhathisa Uxinzelelo kunye neSivuno: I-Paclobutrazol (i-Paclo) yehlisa ubude bezityalo kwaye iphucula amandla okufunxa kwenkqubo yeengcambu, okukhokelela ekunyusweni kwesivuno serayisi se-60 catties kwi-0.067 yeehektare).

2.2 ◇ Uzinziso oluPhezulu: Ukungahambi kakuhle kunye noHlumo oluBabekileyo
Imeko eqhelekileyo ene-2,4-D: Kwiindawo ezixineneyo ezingaphantsi kwe-30 mg/kg, yenza ukuthintela ukuwisa kwesiqhamo; nangona kunjalo, ekugxininiseni okungaphezulu kwe-500 mg/kg, ngokukhawuleza iguqula ibe yi-herbicide-ebangela ukuba amaqabunga e-tomato aphuhlise ukubonakala kwe-"fern-leaf" efana nosulelo lwentsholongwane, kwaye kubangele ukuhla ngokukhawuleza kwesivuno.

Ukusetyenziswa kwe-Ethephon egqithisileyo: Xa isetyenziselwa ukuvuthwa kweebhanana, ukugxila okungaphezulu kwe-2,000 mg/kg kubangela ukuba isiqhamo sibe mdaka, nto leyo eyenza ukuba singathengiswa ngokupheleleyo.

Ngokucacileyo, idosi ichaza isiphumo, kwaye ifestile yokhuseleko imxinwa kakhulu.


3. Izitshixo eziNtathu zokwenza ukuba iziLawuli zokuKhula kweZityalo zisebenze *Kuwe*
3.1 ◇ Qhagamshelana neLeyibhile, kodwa Nika Ingqalelo ekufutshane kwi "Temperament" yeSityalo
Izityalo ezahlukeneyo zibonisa uvakalelo olwahlukileyo kakhulu kwisithako esisebenzayo esifanayo. Ngokomzekelo, utamatisi ubonakala "uyamkela" i-gibberellins ngaphandle kwengxaki, kanti iikomkomere eziphathwe ngento efanayo zithandwa kakhulu ekuphuhliseni "iingcebiso ezicacileyo." Ngaphaya koko, nesityalo esinye sinokuba "guquguqukayo"-siphendule ngokwahlukileyo ngokuxhomekeke kwinqanaba elithile lokukhula. Ngoko ke, kufuneka uqale uqonde iqondo lobushushu elikhethekileyo lesityalo phambi kokuba wenze isigqibo sokutshiza okanye ukudipha, okanye nokuba ufake isilawuli sodwa okanye kumxube.

3.2 ◇ Jonga iMozulu, kodwa Gxininisa ngakumbi kwi "Efficacy Window"
Amaqondo obushushu aphezulu kunye nokukhanya okukhulu kwelanga kukhawulezisa ukubola kwezilawuli zokukhula, ngelixa amaqondo obushushu aphantsi adityaniswe nomswakama ophezulu angakhokelela ngokulula kwi-phytotoxicity (ukulimala kweekhemikhali). Ukufunxa kukhawuleza kakhulu xa i-stomata yamagqabi ivuleke ngokupheleleyo; ukuba ufaka isicelo phambi kwemvula, qiniseka ukuba wongeza i-agent agent. Khumbula esi sicengcelezo silula: "Emva kokuba umbethe wakusasa ukoma, ngaphambi kokuba ilanga litshone emva kwemini" -oku kwenza ifestile yesicelo esifanelekileyo kuninzi lwabalawuli bokukhula.

3.3 ◇ Yinkosi kwiTeknikhi, kwaye ubeke phambili "Ukunciphisa okwesibini"
Izisombululo zesitokhwe ezigxininiswe kakhulu *kufuneka* zingene kwidilution yesibini. Okokuqala, xuba ugxininiso kunye nomlinganiselo omncinci wamanzi ukuze wenze i-paste epholileyo; ke, yongeza amanzi aseleyo ukufikelela umthamo wokugqibela kwaye uqinisekise umxube isitshizi efanayo. Xa ulungiselela isisombululo, nxiba iiglavu zerabha kunye nezibuko zokukhusela ukukhusela ukudibanisa kwesikhumba kunye nokuphefumla. Impazamo ye-1% kuphela kwi-dilution ratio inokubangela ukuncipha kwe-10% ekusebenzeni kwemveliso.

4. Umbono wekamva: Ukuvumela iDatha "Ithethe" kuLawulo lokuKhula
Ngokuvuthwa kwetekhnoloji ye-biosensor kunye nesantya esiguquguqukayo sokutshiza nge-drones, ummiselo ochanekileyo-ukuya kufikelela kwinqanaba lezityalo okanye namagqabi athile-uye waba yinyani. Abalimi badinga kuphela igalelo leempawu zezityalo abazinqwenelayo kwi-app ephathwayo; inkqubo iya kuthi emva koko ibale ngokuzenzekelayo i-optimal concentration kunye ne-spray trajectory, eyenza "i-targeted replenishment" indlela-ukusebenzisa kanye oko kuyimfuneko, ngokuchanekileyo apho ifuneka khona. Oku akugcini nje ukunciphisa imingcipheko yokusingqongileyo ehambelana nokusetyenziswa kweekhemikhali ngokugqithisileyo kodwa iqinisekisa ukuba idola nganye etyaliwe iguqulela ngokuthe ngqo kwisivuno esibambekayo.

5. Ukuqukumbela: Yamkela iziLawuli zoHlumo ngokuQinisekisayo ukuQhuba ezoLimo ngokukhawuleza, ukuzinza, kunye nokuQobelelana
Izilawuli zokukhula kwezityalo azizozilo ziloyikekayo okanye unyango olungummangaliso. Amandla abo okwenene okunyusa izivuno anokuvulwa kuphela xa evavanywa ngaphakathi kwimeko ebanzi yomjikelo wokukhula kwezityalo zendalo kunye nokhuseleko lwendalo. Vumela idatha ithethe, vumela itekhnoloji inike isikhokelo, kwaye abalimi bavune izibonelelo-le yindlela yokwenyani eya kwikamva elisebenzayo nelizinzileyo kwezolimo.
