Feteleza waufa nthawi zambiri amagwiritsidwa ntchito kupititsa patsogolo nthaka komanso kupereka michere pakukula kwa mbewu.Zitha kuwolanso mwachangu zikalowa m'nthaka, ndikutulutsa michere mwachangu.Chifukwa feteleza wa powdery solid organic amamwa pang'onopang'ono, feteleza wa ufa wopangidwa ndi organic amasungidwa nthawi yayitali kuposa feteleza wamadzimadzi.Kugwiritsa ntchito feteleza wachilengedwe kwachepetsa kwambiri kuwonongeka kwa mbewuyo komanso chilengedwe cha nthaka.
Feteleza wa organic amapereka organic zinthu kunthaka, motero amapereka zomera ndi zakudya zomwe zimafunikira kuti zithandize kumanga dothi labwino, osati kuwononga.Choncho feteleza wachilengedwe amakhala ndi mwayi waukulu wamabizinesi.Ndi zoletsa pang'onopang'ono komanso kuletsa kugwiritsa ntchito feteleza m'maiko ambiri ndi m'madipatimenti oyenera, kupanga feteleza wachilengedwe kudzakhala mwayi waukulu wabizinesi.
Zilizonse zopangira organic zitha kuwira mu kompositi.M'malo mwake, kompositi imaphwanyidwa ndikuwunikiridwa kuti ikhale feteleza wamtengo wapatali wogulitsidwa wa powdery organic.
1. Chimbudzi cha nyama: nkhuku, ndowe za nkhumba, ndowe za nkhosa, kuimba ng’ombe, manyowa a akavalo, manyowa a akalulu, ndi zina zotero.
2, zinyalala zamakampani: mphesa, viniga wosasa, zotsalira za chinangwa, zotsalira za shuga, zinyalala za biogas, zotsalira za ubweya, ndi zina zambiri.
3. Zinyalala zaulimi: udzu wa mbewu, ufa wa soya, ufa wa thonje, ndi zina zotero.
4. Zinyalala zapakhomo: zinyalala zakukhitchini.
5, matope: matope a m'tauni, matope a mitsinje, matope a fyuluta, ndi zina zotero.
Njira yopangira feteleza waufa monga ufa wa neem bread, cocoa peat powder, oyisitara ufa wa chipolopolo, ndowe zouma za ng'ombe, ndi zina zotere. Zimaphatikizanso kupanga kompositi, kuphwanya kompositi yomwe yatuluka, ndikuyesa ndikuyika.
Mzere wopangira feteleza wopangidwa ndi ufa uli ndi ukadaulo wosavuta, zida zotsika mtengo zogulira, komanso ntchito yosavuta.
Timapereka chithandizo chaukadaulo chaukadaulo, kukonzekera malinga ndi zosowa za makasitomala, zojambula zamapangidwe, malingaliro omanga patsamba, ndi zina zambiri.
Njira yopanga feteleza waufa: kompositi - kuphwanya - sieve - kuyika.
1. Kompositi
Organic zopangira nthawi zonse ikuchitika kudzera dumper.Pali magawo angapo omwe amakhudza kompositi, monga kukula kwa tinthu, chiŵerengero cha carbon-nitrogen, madzi, mpweya wa okosijeni ndi kutentha.Chidwi chiyenera kuperekedwa ku:
1. Ponyani zinthuzo kukhala tizigawo ting'onoting'ono;
2. Mpweya wa carbon-nitrogen wa 25-30:1 ndiye malo abwino kwambiri opangira manyowa abwino.Mitundu yambiri ya zipangizo zomwe zimalowa, mwayi waukulu wowonongeka bwino ndikusunga chiŵerengero choyenera cha C: N;
3. Chinyezi choyenera cha kompositi nthawi zambiri chimakhala 50% mpaka 60%, ndipo Ph imayendetsedwa pa 5.0-8.5;
4. Kupukuta kumamasula kutentha kwa mulu wa kompositi.Zinthu zikawonongeka bwino, kutentha kumachepa pang'ono ndi kugubuduza, ndiyeno kubwereranso ku mlingo wapitawo mkati mwa maola awiri kapena atatu.Ichi ndi chimodzi mwa ubwino wamphamvu wa dumper.
2. Kuphwanya
Chopukusira choyima chimagwiritsidwa ntchito kuphwanya kompositi.Pophwanya kapena kugaya, zinthu zotsekeka mu kompositi zitha kuwola kuti zipewe zovuta pakuyika ndikusokoneza mtundu wa feteleza wachilengedwe.
3. Sieve
Makina a sieve odzigudubuza samachotsa zonyansa zokha, komanso amasankha zinthu zosayenera, ndipo amanyamula kompositi ku makina a sieve kudzera pa conveyor lamba.Njirayi ndi yoyenera pamakina a sieve a ng'oma okhala ndi mabowo apakatikati a sieve.Sieving ndi yofunika kwambiri posungira, kugulitsa ndi kugwiritsa ntchito kompositi.Sieving imawongolera kapangidwe ka kompositi, imapangitsa kuti kompositi ikhale yabwino, ndipo imakhala yopindulitsa pakuyika ndi kunyamula.
4. Kuyika
Feteleza wosefayo amatumizidwa kumakina oyikamo kuti agulitse feteleza waufa yemwe angagulitsidwe mwachindunji kudzera mu sikelo, nthawi zambiri ndi 25 kg pa thumba kapena 50 kg pa thumba ngati voliyumu yapaketi imodzi.
