Ukwandiswa kweeClay Clay njengezityalo ezikhula kwimithombo yeendaba
1. Igama lemveliso: Udongwe olwandisiweyo
I-LECA (iKhaphukhaphu eyandisiweyo yoCingo oluCocekileyo) ngumdibaniso owenziwe ngodongwe olwandisiweyo ngomyinge we-1200 ℃ kwikhiliti ejikelezayo,
I iigesi ezivelisayo ziyandiswa ngamawaka eebhubhu ezincinci ukuba nje obu bushushu buye buvele
ngabaninzi Iivawu kunye nobusi bezinyosi kule mida ejikeleze imilo xa izinto ezisinyibilikisayo zibanda.
I-LECA yenziwe dibanisa ezinokubakho izibonelelo ezininzi ngokuthelekiswa nendalo yokukhanya okulula kunye
ukusukela ngo-1917 usebenzise ngaphantsi igama lohlobo ezahlukeneyo eMelika naseYurophu amazwe.
Iibhola ze-2.Garden Clay:
Iiblukhwe eziLayitiweyo ezinobunzima obucekeceke yeyona ndawo ikhulayo kuzo zonke izityalo. Inika okona kulungileyo amanzi kunye nokugcinwa kokufuma.Yisebenzise njenge-mulch yokuhlobisa yezityalo embizeni, kwizityalo zomhlaba, njenge-an yongeza umxube kwizikhongozeli, kunye nesakhelo esingezantsi samanzi.Isetyenziswe ngokubanzi ekukhuleni kwe-hydroponic kwaye ayithathi cala. Iipores ezisematyeni zigcina amanzi kwaye zikhuphe amanzi xa kufuneka njalo ukubonelela okuhle indalo yokuphuhliswa kwengcambu. Ilungele iiroses, ii-orchid kunye nazo zonke iintlobo zeziqhamo kunye nemifuno.Ukudityaniswa kokukhanya kodongwe okuhlanganisiweyo, okubizwa njalo ngokuba "kukukhula ilitye", kulungele ukukhula ngaphakathi kwehydroponic ngenxa yobume bayo bokungathathi cala-Umbumba webumba lomdongwe awunazo iasidi okanye iimpawu zealkaline.
3. Inzuzo
I-LECA inenzuzo ezininzi kwezolimo nakwimihlaba yomhlaba, isetyenziswa njengendawo ekhulayo kwiinkqubo ze-Hydroponics, kwaye
zidityaniswe nezinye iindlela ezikhulayo ezinje ngomhlaba kunye ne-peat yokuphucula amanzi, ukugcina amanzi ngexesha lembalela,
faka iingcambu ngexesha lesithwathwa kwaye ubonelele ngeengcambu ngamanqanaba eoksijini akhuthaza ukukhula okunamandla kakhulu. I-LECA inokuxuba
ngomhlaba oqhelekileyo omnandi ukwenzela ukunciphisa ubunzima bezityalo kunye nemihlaba yomhlaba.
