Yakawedzera Clay Mapepa semakwenzi anokura media
1. Chigadzirwa zita: Yakawedzera ivhu
LECA (Lightweight Yakawedzera Clay Aggregate) muunganidzwa wakagadzirwa nevhu rakawedzerwa paavhareji 1200 ℃ mune inotenderera kiln,
the goho rinoburitswa rinowedzerwa nezviuru zvenguva diki mabhureki sekureba uku tembiricha uye porosity ichaonekwa
nevakawanda voids nemazinga euchi kune aya anotenderera chimiro zvinosangana kana zvinyungudutswa zvikaita kutonhora.
LECA yakagadzirwa kuunganidza iyo ine zvakawanda zvakanakira kuenzanisa neyemusikirwo mhenyu uremu hwakaunganidzwa uye
kubva 1917 yakashandisa pasi rakasiyana zita zita mune USA uye Europe nyika.
2.Garden Clay Mabhora:
Isingaremi Yakawedzera Clay mabwe makuru akakura kati svikiro kune zvese zvirimwa. Inopa zvakanakisa kudhirowa pamwe nekuchengetedzeka kwehunyoro.Iishandise sechishongedza mulch yezvidyarwa muhari, mune zvidyarwa pasi, senge wedzera kusanganisa nemidziyo, uye pasi rakadirwa mvura.Inoshandiswawo zvakanyanya mu hydroponic inokura uye ndeye pH isina kwayakarerekera. Iyo pores iri mumabwe inochengetedza mvura uye inoburitsa mvura painenge ichidikanwa saka kupa zvakanakisa nharaunda yekukura midzi. Yakanakira maruva, orchids uye ese marudzi emichero uye miriwo.Chiedza chakawedzera dongo muunganidzwa, zvakare chinowanzonzi "kukura dombo", chakanakira mukati meimba hydroponic kukura nekuda kwezvinhu zvayo zvematongerwo enyika- Bindu revhu pebble harina asidhi kana alkaline maitiro.
3. Kubatsira
LECA ine mikana yakawanda yekurima uye masango, iyo inoshandiswa svikiro riri kukura muHydroponics system, uye
yakasanganiswa nemamwe masvikiro anokura sevhu uye peat kugadzirisa mvura, kuchengetedza mvura panguva yekusanaya kwemvura,
inodzika midzi panguva yechando uye inopa midzi ine huwandu hweakisijeni inosimudzira kukura kwakasimba kwazvo. LECA inogona kusanganisa
neyakajairika rinotapira ivhu kuitira kudzikisa huremu hwezvirimwa nevhu revhu revhu.
