iindaba

Kwimeko yezolimo zanamhlanje ezitshintsha rhoqo, abalimi kunye neengcali zezolimo bahlala befuna izisombululo ezizinzileyo zokwandisa isivuno sezityalo ngelixa benciphisa impembelelo yokusingqongileyo. Phakathi kolu phando lokusebenza kakuhle, kukho into enye etshintshe umdlalo kwi-physiology yezityalo: i-DA-6, eyaziwa ngokwesayensi njengeI-2-Diethylaminoethyl hexanoate, kwaye idla ngokubizwa ngokuba yi-DA-6 kushishino. Ngokungafaniyo neehomoni zemveli ezinyanzela ukukhula ngenxa yokulahlekelwa yimpilo yezityalo, i-2-Diethylaminoethyl hexanoate isebenza njengomlawuli we-metabolic, ivula amandla emfuza ezityalo ukuze kuphunyezwe ukukhula okuqinileyo, ukumelana noxinzelelo oluphezulu, kunye nemveliso esemgangathweni ophezulu kakhulu.

I. Ukuqonda indlela esebenza ngayo i-DA-6 (2-Diethylaminoethyl hexanoate)

Kwisiseko sayo, i-DA-6 ngumlawuli wokukhula kwezityalo obanzi. Indlela yayo yokusebenza ephambili ibandakanya ukulawula ibhalansi yeehomoni zendalo ngaphakathi kwisityalo. Xa isetyenziswa, yonyusa umxholo we-chlorophyll, iproteni, kunye ne-nucleic acid kwizityalo. Oku kwandiswa kwe-biochemical kukhokelela kumazinga aphezulu e-photosynthesis—ahlala ewanyusa ngamanani amaninzi xa kuthelekiswa nezityalo ezinganyangwanga. Ngokukhawulezisa ukuguqulwa kwamandla okukhanya abe ngamandla eekhemikhali, i-DA-6 iqinisekisa ukuba isityalo sivelisa iicarbohydrate ezingaphezulu, ezithi emva koko zithuthwe ziye kwiziqhamo, imbewu, kunye neengcambu.

Ngaphezu koko,I-DA-6ivuselela umsebenzi wee-enzymes eziphambili ezifana ne-peroxidase kunye ne-nitrate reductase. Oku kusebenza kwe-enzyme kukhawulezisa ukwahlukana kweeseli kunye nokwandiswa kwazo, ngakumbi kwizicubu ze-meristematic (amanqaku okukhula). Isiphumo asikokuba zizityalo "ezinde" kuphela, kodwa zizityalo ezomeleleyo ngokwesakhiwo ezineziqu ezityebileyo namagqabi amakhulu, nto leyo eyenza isiseko esiqinileyo sesivuno esiphezulu.

II. Iimpawu eziphambili kunye neenzuzo

Into eyahlula i-DA-6 kubalawuli besizukulwana esidala abanjengo-gibberellins okanye i-auxins yiprofayili yayo yokhuseleko eyahlukileyo kunye nokuguquguquka kwayo.

Ukhuseleko kunye nokungatyhefi: Enye yezona nzuzo zibalulekileyo ze-DA-6 kukhuseleko lwayo. Ayinabungozi ebantwini nakwizilwanyana kwaye ayiqokeleli emhlabeni okanye kwiinkqubo zamanzi. Iyawohloka ngokwendalo, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo kwiinzame zokulima eziluhlaza kunye nezokwemvelo.

Umda woKhuseleko oluBanzi: Abalimi badla ngokuxhalaba malunga "netyhefu ye-phytotoxicity" (ukutsha kweekhemikhali) xa besebenzisa abalawuli bokukhula. I-DA-6 inoluhlu olubanzi kakhulu loxinzelelo lokhuseleko (ukusuka kwi-1 ppm ukuya kwi-100 ppm). Nokuba isetyenziswe kumanqanaba aphezulu kancinci kunokuba kucetyisiwe, ayifane ibangele ingozi, nto leyo enika ukhuseleko kwiimpazamo zokusetyenziswa.

Ukuhambelana: I-DA-6 ihambelana kakhulu nezinye iikhemikhali zezolimo. Ingaxutywa nezibulali zinambuzane ezine-asidi okanye ezingathathi cala, izibulali zinambuzane, kunye nezichumisi. Enyanisweni, ihlala isebenza njenge-synergist, iphucula ukufunxwa kunye nokusebenza kakuhle kwezi zinto zingeniswayo, ngaloo ndlela inciphisa inani lilonke leekhemikhali ezifunekayo.

Isiphumo Esihlala Ixesha Elide: Le khompawundi ibonisa uphawu "lokukhululwa kancinci" ngaphakathi kwizicubu zesityalo. Inxalenye yesithako esisebenzayo isebenza ngoko nangoko, ngelixa okuseleyo kugcinwa kwaye kukhululwa kancinci ngokuhamba kwexesha. Oku kuqinisekisa isiphumo esihlala ixesha elide kulo lonke umjikelo wokukhula kwesityalo, kuthintela "ukuqhekeka" okuhlala kubonakala ngeehomoni ezisebenza ngokukhawuleza.

III.Izicelo Kwiintlobo Ngeentlobo Zezityalo

Ukuguquguquka kwe-DA-6 kwenza ukuba isetyenziswe phantse kuzo zonke iintlobo zezityalo zezolimo.

1. Izityalo zasemasimini (Ingqolowa, Umbona, Irayisi): Ukufakwa ngexesha lokudibana okanye ukuqalisa kukhuthaza ukuhluma, kuthintela ukuhla (ukuwa), kwaye kwandisa inani leenkozo nge-spike nganye. Uvavanyo lwasemasimini luye lwabonisa ukunyuka kwesivuno okususela kwi-10% ukuya kwi-20%.

2. Imifuno kunye nemifuno eluhlaza: Kwizityalo ezifana nespinatshi, ilettuce, kunye nekhaphetshu, i-DA-6 (Diethyl Aminoethyl Hexanoate) ikhuthaza ukukhula ngokukhawuleza kwamagqabi kunye nokuqina. Iyalibazisa ukuguga (ukwaluphala), igcina imifuno itsha kwaye iluhlaza ixesha elide, nto leyo eyandisa ixesha lokuvuna kwaye iphucule ukuthengiswa.

3. Imithi yeziqhamo: Isetyenziswa ngexesha lokudubula nokubeka iziqhamo, inciphisa kakhulu ukuhla kweziqhamo. Ngexesha lokukhula kweziqhamo, ikhuthaza ubungakanani obufanayo kwaye iphucula ukuqokelelwa kweswekile, nto leyo ebangela iziqhamo ezimuncu nezinombala ongcono.

4. Izityalo zeengcambu (Iitapile, Iitapile ezimnandi): Inceda ekuthuthweni kwezondlo ukusuka emagqabini ukuya kwiingcambu ezingaphantsi komhlaba, nto leyo ekhokelela ekuvunweni okukhulu nokunzima.

IV. Ukuphucula Ukumelana Noxinzelelo

Utshintsho lwemozulu luzise iipateni zemozulu ezingaqikelelweyo, nto leyo eyenza ukuba ukuqina kwezityalo kube yinto ebaluleke kakhulu kunangaphambili. I-DA-6 idlala indima ebalulekileyo apha. Ngokulawula ukuvalwa kwesisu kunye nokuphucula ukulungiswa kwe-osmotic, inceda izityalo zigcine amanzi ngexesha lembalela. Ngokufanayo, inyusa imveliso yee-enzymes ezikhuselayo ezisusa ii-free radicals, zinceda izityalo ziphinde zilulame ngokukhawuleza emva komonakalo weqhwa okanye uxinzelelo lobushushu. Esi siphumo "somgaqo-nkqubo we-inshorensi" senza ukuba sibe luncedo kakhulu kwezolimo kwiindawo ezingaphelelanga.

V. Isiphelo

Njengoko inani labantu behlabathi likhula kwaye umhlaba olimekayo uncipha, uxinzelelo lokuvelisa ukutya okuninzi oluzinzileyo luyanda.I-DA-6 (iDiethyl Aminoethyl Hexanoate)Inika isisombululo sesayensi, esikhuselekileyo, nesisebenzayo kulo mceli mngeni. Ngokusebenzisa ngcono imetabolism yangaphakathi yesityalo endaweni yokunyanzela ukukhula okwenziwayo, ihambelana ngokugqibeleleyo neenjongo zolimo lwanamhlanje nolunobuhlobo nokusingqongileyo. Nokuba ulawula iihektare ezinkulu zengqolowa okanye igadi yeziqhamo ethambileyo, ukudibanisa iDiethyl Aminoethyl Hexanoate kwisicwangciso sakho solawulo lwezityalo linyathelo eliya kwimveliso ephezulu kunye nomgangatho ophezulu.
