Ndeipi pfungwa yekuchengetedzwa kwemiti?
Kudzivirirwa kwechirimwa kunoreva kushandiswa kwematanho akazara kuchengetedza hutano hwezvirimwa, kuvandudza goho nemhando, uye kuderedza kana kubvisa tumbuyu, zvirwere, sora nezvimwe zvipenyu zvisingadiwi. Kudzivirirwa kwechirimwa chikamu chakakosha chemaitiro ekugadzira zvekurima, nechinangwa chekuona kukura kwakajairwa uye kusimukira kwezvirimwa, kuvandudza goho nemhando yezvirimwa, uye kuchengetedza nharaunda uye hutano hwevanhu. Kudzivirirwa kwechirimwa kunosanganisira kudzivirira, kuongororwa, kurapwa, kutarisa uye manejimendi. Pakati pavo, kudzivirira ndiyo inonyanya kukosha yekubatanidza, kusanganisira kutora biological, muviri, makemikari uye dzimwe nzira kuderedza mukana wezvipembenene nezvirwere. Kuongorora (diagnosis) kuona nekuronga matambudziko akaita sezvirwere netumbuyu kuitira kutora matanho ekudzivirira nekudzora.
Kune nzira dzakawanda uye nzira dzekudzivirira chirimwa. Pamusoro pechinyakare chemakemikari emishonga yekuuraya zvipembenene uye yebiological nzira dzekudzora senge vavengi venyama, vanopikisa, misungo, nezvimwewo, kutonga kwemuviri uchishandisa mulch, chiedza, tembiricha uye mamwe matanho, uye agronomic kudzora nzira senge tillage system, intercropping. , kutenderera uye mamwe matanho. Nzira idzi dzose dzine chinangwa chekudzivirira chirimwa.
Pamusoro pekuchengetedza kukura nekusimukira kwezvirimwa, kuchengetedzwa kwezvirimwa kunogonawo kuchengetedza nharaunda yezvakatipoteredza uye hutano hwevanhu. Semuenzaniso, kushandiswa kwakanyanya kwemakemikari ekuuraya zvipembenene mukugadzirwa kwekurima kunokonzeresa kusvibiswa uye kukuvadza kune ivhu, zvitubu zvemvura, mweya, mhuka nezvirimwa, nepo biological control uye agronomic control zvine hushamwari kwezvakatipoteredza uye zvakagadzikana, uye zvinobatsira kuchengetedza nharaunda uye kuvandudzwa kwehutano hweecosystem.
Magadzirirwo edu ekukura kwezvirimwa anobatsira zvirimwa kukura zvine hutano, uye zvigadzirwa zvinenge zvakakwana,kusanganisira chirimwa kukura regulator, chirimwa kukura retardant, chirimwa kukura inhibitor uye zvimwe Featured zvigadzirwa.Kugamuchirwa kuti utarise runyorwa rwechigadzirwa chenhaurirano.
