Foliar Fertilization uye Kushandisa Pesticide Inogona Kuitwa Panguva imwe chete

Mafetereza emakemikari nemishonga yezvipembenene zvinhu zvinonyanya kukosha kugadzira mukurima kwemazuva ano. Kuti goho riwedzere uye kunaka, varimi vari kuramba vachiisa fetereza yemakemikari kakawanda uye nemhando dzakasiyana. Foliar fertilization, nekuda kwekuderera kwayo kushandiswa kwefetereza uye kukurumidza kushanda, yave nzira inowanzoshandiswa kuvarimi, kunyanya varimi vemichero nemiriwo. Nekune rimwe divi, varimi vanogara vachimwaya mishonga yekuuraya zvipembenene nezvirwere. Vanhu vazhinji vanoedza kusanganisa mishonga yezvipembenene nefetereza pamwe chete kuti ishandiswe panguva imwe chete, vachivavarira kuchengetedza vashandi nekuvandudza kushanda zvakanaka.

Kiyi yekubudirira kusanganisa ndeyekuti fungicides uye zvipembenene, pamwe nemishonga yezvipembenene nemafetiraiza, haifanirwe kuita kemikari, uye haifanire kukanganisa maitiro ezvipembenene nefetiraiza, senge solubility, kumiswa, uye emulsification. Izvo hazvifanirwe kukanganisa kushanda kweumwe neumwe. Ehe, kusavapo kwekuita kwemakemikari kunodzivirirawo kuwedzera muchetura kuvanhu, mhuka, uye zvirimwa, uye kunodzivirira kuparara kwemishonga yezvipembenene nefetereza. Kubva pamaonero ekuchengetedza kushanda zvakanaka, isu tinotoziva kuti mamwe mishonga yezvipembenene haigone kusanganiswa nealkaline pesticides (lime sulfur, Bordeaux musanganiswa), senge tumbuyu seflufenoxuron, diflubenzuron, acetamiprid, uye tin makomisheni, uye fungicides senge mancozeb, aluminium trifoxfox, eth simbi, aluminium trifox, eth simbi Ketoconazole, epoxiconazole, iprodione, kasugamycin, polyoxin, uye nystatin. Nekuwedzera, haifanirwe kusanganiswa nealkaline kana kuti ine alkaline fetireza isina simba seammonium carbonate, wood ash, calcium magnesium phosphate, diammonium phosphate, borax, uye ammonium molybdate.

Mamwe magadzirirwo ekukura kwezvirimwa, akadai segibberellin, chlormequat, uye ethephon, haafaniriwo kusanganiswa nemishonga yezvipembenene yealkaline kana mafetireza, kana zvisina kudaro, anoora uye asingashande. Kana mishonga yesora ikashandiswa pakurapa ivhu, kazhinji haina njodzi, kunyanya kana imwe neimwe yakasanganiswa nevhu rakanyorova (kana mvura) isati yasanganiswa kuti ishandiswe. Nekudaro, kana yakashandiswa kune foliar application, kungwarira kwakanyanya kunodiwa. Kunyangwe madhasi akakwira zvishoma kana kushandiswa zvisina kuenzana kunogona kukonzera phytotoxicity, saka kazhinji haifanirwe kusanganiswa nefotereza. Kana kusanganiswa kuchidikanwa, mushonga wesora unofanira kutanga wagadzirirwa semushonga wemasheya, uye fetereza inofanirawo kunyungudutswa mumvura isati yasanganiswa nemhinduro yemasheya. Iko kusanganiswa kunofanira kugadzirirwa uye kushandiswa pakarepo. Biopesticides haifanirwe kusanganiswa nemakemikari fetiraiza kana fungicides, sezvo fetiraiza uye fungicides zvinogona kuuraya anobatsira tupukanana aainawo, zvichideredza kushanda kwawo. Pamusoro pezvo, kutariswa kunofanirwa kupihwa kune mirau chaiyo maererano nekusanganiswa kweimwe mishonga yezvipembenene. Semuenzaniso, fungicide inonzi chlorobromoisocyanuric acid, inogona kudzora fungal, bhakitiriya, uye kunyange zvirwere zvehutachiona, mushonga unokosha, asi une mutemo unoti "haufaniri kusanganiswa nemamwe mishonga." Nekuwedzera, haifanirwewo kusanganiswa nemafetireza.
