Kufotokozera Kagwiritsidwe Ntchito Kazinthu
Muulimi wamkuwa wa sulphate, yankho la mkuwa lili ndi ntchito zambiri.Amagwiritsidwa ntchito kwambiri popewa komanso kuchiza matenda osiyanasiyana monga zipatso, nandolo, mbatata, etc., ndi zotsatira zabwino.Copper sulphate angagwiritsidwe ntchito kupha bowa.Amasakanizidwa ndi madzi a mandimu kuti apange kusakaniza kwa Bordeaux, komwe kumagwiritsidwa ntchito ngati njira yoletsa kubadwanso kuti ateteze bowa pa mandimu, mphesa ndi mbewu zina ndikuletsa madera ena owola.Feteleza wa microbial ndi mtundu wa feteleza wamtundu wina, womwe ukhoza kupititsa patsogolo mphamvu ya chlorophyll.Chlorophyll sidzawonongeka msanga, komanso ingagwiritsidwe ntchito kuchotsa algae m'minda ya mpunga.
Kusakaniza kwa copper sulfate ndi madzi a mandimu kumatchedwa "Bordeaux mix".Ndi mankhwala odziwika bwino opha bowa amene amatha kuletsa ndi kuletsa majeremusi a zomera zosiyanasiyana monga mitengo ya zipatso, mpunga, thonje, mbatata, fodya, kabichi, ndi nkhaka.Kusakaniza kwa Bordeaux ndi bactericide yoteteza, yomwe imalepheretsa kumera kwa spore kapena mycelial kukula kwa mabakiteriya a pathogenic potulutsa ayoni amkuwa osungunuka.Pansi pa acidic mikhalidwe, ma ayoni amkuwa akatulutsidwa mochulukirapo, ma cytoplasm a mabakiteriya oyambitsa matenda amathanso kulumikizidwa kuti achite bactericidal.Pankhani ya chinyezi chambiri komanso mame kapena filimu yamadzi pamasamba, mankhwala ake ndi abwino, koma n'zosavuta kutulutsa phytotoxicity kwa zomera zomwe sizilekerera mkuwa.Zili ndi zotsatira zokhalitsa ndipo zimagwiritsidwa ntchito kwambiri popewera ndi kulamulira matenda osiyanasiyana a masamba, mitengo ya zipatso, thonje, hemp, etc. Ndiwothandiza kwambiri polimbana ndi matenda a masamba monga downy mildew, anthracnose, ndi kuchedwa kwa mbatata.

Ndi kuyimitsidwa kwamtambo wabuluu wopangidwa ndi pafupifupi 500 magalamu a copper sulfate, 500 magalamu a quicklime ndi 50 kilogalamu ya madzi.Gawo la zosakaniza likhoza kuwonjezeredwa kapena kuchepetsedwa moyenera malinga ndi zosowa.Chiyerekezo cha copper sulfate ndi quicklime ndi kuchuluka kwa madzi omwe awonjezeredwa kuyenera kutengera kukhudzika kwa mtengo wa sulfate ndi laimu (copper sulfate imagwiritsidwa ntchito popanga copper-sensitive, ndipo laimu wochepera amagwiritsidwa ntchito ngati laimu- tcheru), komanso zinthu zowongolera, nyengo yogwiritsira ntchito ndi kutentha.Zimatengera kusiyana.Zomwe zimagwiritsidwa ntchito popanga madzi a Bordeaux popanga ndi: Bordeaux madzi laimu ofanana chilinganizo (copper sulfate: quicklime = 1: 1), angapo voliyumu (1: 2), theka voliyumu (1:0.5) ndi angapo voliyumu (1: 3-5) .Kumwa madzi nthawi zambiri kumakhala 160-240.Kukonzekera njira: Sungunulani mkuwa sulphate mu theka la kumwa madzi, ndi Sungunulani quicklime mu theka lina.Mukatha kusungunuka, pang'onopang'ono kutsanulira zonse mu chidebe chosungira nthawi imodzi, ndikuyambitsa nthawi zonse.Ndikothekanso kugwiritsa ntchito 10% -20% ya quicklime yosungunuka m'madzi ndi 80% -90% mkuwa wa sulphate wosungunuka m'madzi.Pambuyo posungunuka, pang'onopang'ono tsanulirani njira yothetsera mkuwa wa sulphate mu mkaka wa mandimu ndikugwedeza pamene mukutsanulira kuti mupeze Bordeaux madzi.Koma musathire mkaka wa laimu mu mkuwa wa sulphate yankho, apo ayi ubwino udzakhala wosauka ndipo zotsatira zake zidzakhala zoipa.
Kusamalitsa
Ziwiya zachitsulo zisagwiritsidwe ntchito pokonzekera, komanso zida zopoperazi ziyenera kutsukidwa munthawi yake kuti zisawonongeke.Sizingagwiritsidwe ntchito pamasiku amvula, masiku a chifunga, komanso pamene mame sauma m'mawa, kuti apewe phytotoxicity.Sizingasakanizidwe ndi mankhwala amchere monga laimu sulfure osakaniza.Nthawi pakati pa mankhwalawa ndi masiku 15-20.Siyani kugwiritsa ntchito masiku 20 zipatso zisanakololedwe.Mitundu ina ya maapulo (Golden Crown, etc.) imakhala ndi dzimbiri pambuyo popopera mankhwala osakaniza a Bordeaux, ndipo mankhwala ena ophera tizilombo angagwiritsidwe ntchito m'malo mwake.
