| Pesticide Chemistry | Inosarudza solubility, volatility, kugadzikana, uye kuderedza nzira. |
| Kunaya Kwemvura Uye Kudiridza | Kupesvedzera leaching, kumhanya, kutakura, uye kuwanikwa kwemishonga yezvipembenene. |
| Maitiro Okushandisa | Inogona kuwedzera kana kuderedza kushingirira, kufamba, uye kutakura. |
Mibvunzo Inonyanya Kubvunzwa Nezvezvinhu Zvinokonzera Kuparara Kwemushonga Muvhu
1. Ndezvipi zvinhu zvikuru zvinokonzeresa kuparara kwemishonga yezvipembenene?
Zvinhu zvikuru zvinosanganisira kuumbwa kwevhu, organic matter, pH, microorganisms, mwando, tembiricha, chiedza chezuva, kemisitiri yemishonga yezvipembenene, kunaya kwemvura, kudiridza, uye kushandisa maitiro.
2. Ivhu pH rinokanganisa kuramba kwemishonga yezvipembenene here?
Ehe. Ivhu pH rinogona kushandura pesticide adsorption, hydrolysis, solubility, microbial chiitiko, uye kugadzikana kwemakemikari, kunyangwe mhedzisiro yacho ichisiyana pakati pemapoka ezvipembenene.
3. Ko organic matter inowedzera mishonga yezvipembenene here?
Organic matter inogona kusunga mamorekuru emishonga yezvipembenene zvakasimba, zvichideredza kuwanikwa nekukasira dzimwe nguva zvichiwedzera nguva apo masarira anoramba akachengetwa mukati mevhu.
4. Hunyoro hunokanganisa sei kuparara kwemishonga yezvipembenene?
Kunyorova kwakaringana kunowanzo tsigira kuita kwemicrobial uye kuita kwemakemikari, nepo kuoma kwakanyanya kana zvakanyanya kuzara mamiriro anogona kushandura nzira dzekuora uye mitengo.
5. Tembiricha inogona kukanganisa kuputsika kwemishonga yezvipembenene?
Ehe. Mamiriro ekudziya anowanzo wedzera kemikari reaction rates uye microbial chiitiko, nepo inotonhorera inononoka maitiro aya uye inobvumira zvakasara kuti zvirambe zviripo.
6. Chiedza chezuva chinoderedza mishonga yezvipembenene muvhu here?
Chiedza chezuva chinogona kukanganisa mimwe mishonga inouraya zvipembenene kuburikidza nephotolysis, kunyangwe nzira iyi isinganyanyi kukosha mushure mekunge masara apinzwa mukati kana kuchengetedzwa nezvidimbu zvevhu.
7. Nei mishonga yezvipembenene ichigona kuramba iripo kwenguva refu mune dzimwe nzvimbo?
Misiyano yezvimiro zvevhu, mamiriro ekunze, nharaunda dzine utachiona, kemisitiri yemishonga yezvipembenene, mwando, nhoroondo yekushandiswa, uye maitiro ekutonga anogona kuburitsa nguva dzakasiyana dzekushingirira.
8. Varimi vangaderedza sei kutakura mishonga yezvipembenene?
Varimi vanokwanisa kuderedza kutakura zvinhu nekusarudza zvigadzirwa zvakakodzera, vachitevera mareiro emazita, kuongorora mamiriro ekunze, kugadzirisa madiridziro, kuchengetedza ivhu rine utano, nekucherechedza zvirango zvekuchinjanisa zvirimwa.
Iwe une chero mibvunzo, mazano, kana mipiro? Kana zvirizvo, ndapota inzwa wakasununguka kushandisa bhokisi rekutaura pazasi kugovera pfungwa dzako. Tinokukurudzirawo kuti ugoverane nomutsa mashoko aya nevamwe vangabatsirwa nawo. Sezvo tisingakwanisi kusvika munhu wose panguva imwe chete, tinoonga zvechokwadi rubatsiro rwenyu mukuparadzira shoko. Ndinokutendai zvikuru nerutsigiro rwenyu uye nokugoverana!
