Kukura kwakanaka kwehuswa kunoenderana nekudya kwakasiyana-siyana. Kunyangwe kudya uku kwatovepo muvhu, kuchiri kuda "kuwedzerwa".
1. Sarudza fetereza yakakodzera. Nitrogen haisi chinhu chine huwandu hwakawanda muzvirimwa chete, asiwo chinhu chinovaka muviri chinoda kuwedzerwa zvakanyanya, chichiteverwa nepotassium nephosphorus. Zvinhu zvitatu izvi zvakakosha pakukura nekupora kwezvirimwa, asi kuwanda kana kushoma kwazvo kunokonzera matambudziko ekukura. Nguva, huwandu uye nzira yekuberekesa mbeu zvakanyatsonaka.
Nekuda kwekusiyana kwemamiriro ekunze, ivhu uye mhando dzehuswa, chirongwa chimwe chete chekuberekesa hachigone kushandiswa kune ese makwenzi, asi kuchine misimboti yakajairika. Semuenzaniso, mafetiraiza enitrogen anowanzo kamurwa kuita mafetiraiza enitrogen anoshanda nekukurumidza uye anononoka kuburitsa. Kana huwandu hwefetiraiza yenitrogen inoshanda nekukurumidza hwakanyanya, hunokonzera kukuvara kwefetiraiza. Kusiyana neizvi, kana mafetiraiza enitrogen anononoka kuburitsa chete akashandiswa, uswa hunogona kukura zvishoma nezvishoma mumamiriro ekukura akanaka, uye huchava panjodzi yekukuvadzwa munzvimbo dzisina kunaka nekuda kwekukura kwakashata. Naizvozvo, nzira yakanaka yekuberekesa ndeyekushandisa musanganiswa wefetiraiza yenitrogen inoshanda nekukurumidza uye inononoka kuburitsa. Yakanyanya kunakafetereza yehuswaine mhando mbiri dzefetereza yenitrogen dziri pamusoro apa, dzinogona kugutsa zvinodiwa nemiti zuva nezuva kwenguva yakareba (kazhinji mavhiki matanhatu kusvika gumi nemaviri). Chinyorwa chefetereza chinowanzo ratidza simba refetereza yechigadzirwa uye rudzi rwefetereza yenitrogen iri mairi. Kana usingakwanise kuwana ruzivo rwataurwa pamusoro apa pakurongedza kwechigadzirwa, usachitenge. Pamusoro pezvo, zvinofanira kucherechedzwa kuti mutengo wefetereza yenitrogen inoburitswa zvishoma nezvishoma wakakwira kupfuura wefetereza yenitrogen inoburitswa nekukurumidza.
2. Nguva yakanakisisa yekuisa fetereza Muchidimbu, uswa hunofanira kupfekedzwa fetereza kana huri kukura zvakanaka, zvikasadaro hahudi kupfekedzwa fetereza. Kana mamiriro ekunze (tembiricha, hunyoro nezuva) asina kunaka, fetereza haigone kuita kuti uswa hukure. Tembiricha yakanaka yekukura kweuswa hwemwaka unotonhorera iri pakati pe15.5℃-26.5℃. Mumamiriro ekunze ekuchamhembe, chitubu nematsutso kazhinji ndiyo nguva yekukura kwepamusoro, nepo kukura kwepakati pezhizha kuchinonoka. Uswa hwemwaka unodziya hunokura zvakanaka kana tembiricha iri pamusoro pe26.5℃, saka zvinokurudzirwa kuisa fetereza munguva yekukura kwepamusoro.
3. Kushandisa fetereza nemazvo Kusashandisa fetereza nemazvo hakugone kuvimbisa kuti fertilizer ichashanda zvakanaka. Saka, nzira chaiyo ndeyekuisa huwandu hwakakodzera hwefetereza panzvimbo chaiyo. Zvishandiso zvinonyanya kushandiswa zvekuisa fetereza zvinopfapfaidza, zvinoshandisa fetereza yemvura, uye zvinoshandisa fetereza zvinotenderera kana zvakapararira. Zvinopfapfaidza zviri nyore kushandisa, asi zvakaoma kuisa fetereza zvakaenzana. Zvinoshandisa fetereza yemvura zviri nyore pakuisa kumhanya, asi unofanirwa kuve nechokwadi chekuti uswa hwese hwakafukidzwa. Zvinoshandisa fetereza zvinotenderera pari zvino ndizvo zvinoshandisa fetereza zvakanyanya uye zvakarurama, uye zvinogona kukurumidza kuisa fetereza munzvimbo yakakura. Kuti uwane mhedzisiro yakanaka yekuisa fetereza, iva nechokwadi chekuteerera zvinotevera:
1. Tenga chigadzirwa chemhando yepamusoromuchina wekuparadzira fetereza, ziva mashandiro emuchina wekuparadzira mafetiraiza, chenesa muchina wekuparadzira mafetiraiza mushure mekuushandisa, tanga kufamba usati wabatidza muchina wekuparadzira mafetiraiza, uye dzima muchina wekuparadzira mafetiraiza usati wamira.
2. Isai fetereza kana uswa hwava kukura zvakanaka.
3. Isa muchina wekuparadzira fetireza zvichienderana nezvinodiwa papepa refetireza.
4. Masango ese anofanira kufefeterwa pasina kushaikwa.
5. Dzivisa kushandisa fetereza ine zvidimbu zvikuru kana uchishandisa chinhu chinotenderera chinoshandisa fetereza.
6. Kudiridza nekukasika mushure mekuisa fetereza kunogona kuwedzera kushanda zvakanaka kwefetereza. Zvakanaka kuisa fetereza mvura isati yanaya.
