Ukunwebeka Clay Okunwebekayo njengezitshalo ezikhulayo imidiya
1. Igama lomkhiqizo: Ubumba olunwetshiwe
I-LECA (i-Lightweight Expanded Clay Aggregate) siyisigaxa esenziwe ngobumba olwandisiwe ngokwesilinganiso se-1200 ℃ kwikhola elijikelezayo
le amageyimu wokukhiqiza anwebeka ngezinkulungwane zama-bubble amancane uma nje kuzovela la lokushisa nokuqina
ngabaningi imichilo nezinyosi zezinyosi kulezi zungeza ukwakheka kwendalo lapho izinto ezincibilikisiwe zibanda.
I-LECA yenziwe ukuhlanganisa okunezinzuzo eziningi kuqhathaniswa nemvelo engasindi esilula futhi
kusukela ngo-1917 usebenzise ngaphansi igama lomkhiqizo elihlukile emazweni ase-USA naseYurophu.
Amabhola we-2.Garden Clay:
Amatshe ayisiyaluyalu Onwebhulayo ongasindi, awukhula kahle phakathi kwazo zonke izitshalo. Inikeza okuhle kakhulu amanzi kanye nokugcinwa komswakama.Sebenzisa njenge-mulch yokuhlobisa yezitshalo ezibunjiwe, ezitshalweni zasemhlabathini, njenge-an engeza ukuxubeka ezitsheni, kanye nesendlalelo esingaphansi sedonsa.Ibuye isetshenziswe kabanzi ekukhuleni kwe-hydroponic futhi akuthathi hlangothi. Ama-pores asematsheni agcina amanzi futhi akhulule amanzi lapho kudingeka ngakho ukuhlinzeka okuhle imvelo yokuthuthukiswa kwezimpande. Ilungele ama-roses, ama-orchid kanye nazo zonke izinhlobo zezithelo nemifino.Isigaxa sobumba esinwetshiwe esikhanyayo, futhi esivame ukubizwa nge- "grow rock", silungele ukukhula ngaphakathi kwe-hydroponic ngenxa yezindawo ezingathathi hlangothi- Ingulube yobumba engadini ayinazimpawu ze-acid noma i-alkali.
3. Inzuzo
I-LECA inokusizakala okuningi kwezolimo nemvelo, isetshenziswa njengendawo ekhulayo ezinhlelweni zeHydroponics, futhi
kuxutshwe nezinye izindlela ezikhulayo ezinjengomhlabathi kanye ne-peat ukwenza ngcono ukugeleza, ukugcina amanzi ngezikhathi zesomiso,
faka izimpande ngesikhathi seqhwa futhi unikeze izimpande ngamazinga we-oksijini akhuthaza ukukhula okukhulu. I-LECA ingaxubana
nenhlabathi evamile emnandi ukuze kuncishiswe isisindo sezitshalo nenhlabathi enhlabathi.
