Feteleza akuphwanya zida zapadera
Zida zapadera zophwanyira feteleza zimagwiritsidwa ntchito pophwanya ndi kugaya mitundu yosiyanasiyana ya feteleza kukhala tinthu tating'onoting'ono, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira komanso zogwira mtima zikagwiritsidwa ntchito ku mbewu.Chidachi chimagwiritsidwa ntchito pomaliza kupanga feteleza, zinthu zitawumidwa ndikuzizidwa.
Mitundu ina yodziwika bwino ya zida zophwanyira feteleza ndi izi:
1.Mphero za khola: Mpherozi zimakhala ndi makola angapo kapena mipiringidzo yokonzedwa mozungulira shaft yapakati.Zinthu za feteleza zimadyetsedwa mu khola ndipo pang'onopang'ono zimachepetsedwa kukula ndi mipiringidzo yozungulira.Mphero za khola ndizoyenera kwambiri kuphwanya zinthu zowononga kapena zolimba.
2. Mphero za nyundo: Mpherozi zimagwiritsa ntchito nyundo zozungulira pogaya feteleza.Ndi oyenera kuphwanya zinthu zosiyanasiyana, kuphatikizapo mbewu, chakudya cha ziweto, ndi feteleza.
3. Mphero za tcheni: Zigayozi zimakhala ndi maunyolo angapo ozungulira omwe amaphwanya feteleza akamadutsa pamphero.Mphero zamaketani ndizoyenera kwambiri kuphwanya zinthu zafibrous kapena zolimba.
Kusankhidwa kwa zipangizo zophwanyira feteleza kumadalira zofuna zenizeni za wopanga feteleza, mtundu ndi kuchuluka kwa zipangizo zomwe zikuphwanyidwa, komanso kagawidwe ka kukula kwa tinthu.Kusankha bwino ndi kugwiritsa ntchito zipangizo zophwanyira feteleza kungathandize kuti feteleza azigwira ntchito bwino, zomwe zimabweretsa zokolola zabwino komanso nthaka yabwino.
