Kukonzekera kwa Microencapsulated

M’zaka zaposachedwapa, ndi kufulumira kwa kukwera kwa mizinda ndi kufulumira kwa kusamutsira nthaka, ntchito za kumidzi zaunjikana kwambiri m’mizinda, ndipo kusowa kwa antchito kwakhala kokulirakulira, zomwe zikuchititsa kukwera mtengo kwa ntchito;ndipo chiwerengero cha amayi ogwira ntchito chikuwonjezeka chaka ndi chaka, ndipo anthu ogwira ntchito zachikhalidwe mankhwala akukumana ndi zovuta.Makamaka ndi kupititsa patsogolo kuchepetsa mankhwala ophera tizilombo komanso kuwonjezera mphamvu, kungathe kupititsa patsogolo kuchuluka kwa kagwiritsidwe ntchito ka mankhwala ophera tizilombo, kuchepetsa kuchuluka kwa ntchito, ndi kupereka mpata wabwino wopangira mankhwala opulumutsa anthu pogwiritsa ntchito njira zopepuka.Zokonzekera zopulumutsa ntchito komanso zopulumutsa ntchito monga madontho owaza, ma granules oyandama, mafuta opaka mafilimu, ma U granules, ndi ma microcapsules akhala malo opangira kafukufuku wamabizinesi m'zaka zaposachedwa, kubweretsa mwayi wabwino kwambiri wachitukuko.Kukula kwawo ndikugwiritsa ntchito kwawo kwatenga msika wawukulu m'minda ya paddy motsatizana, kuphatikiza mbewu zina zandalama, ndipo ziyembekezo zake ndizambiri. 

Kukula kwa kukonzekera kopulumutsa ntchito kukuyenda bwino 

M’zaka khumi zapitazi, luso la kupanga mankhwala ophera tizilombo m’dziko langa lakhala likutukuka mofulumira, ndipo kachitidwe kachitukuko kogwirizana ndi chilengedwe kakhala koonekeratu;kuwongolera magwiridwe antchito, kuyang'ana pachitetezo chobiriwira, ndikuchepetsa mlingo ndikuwonjezera magwiridwe antchito ndiyo njira yokhayo yopititsira patsogolo.

Zolemba zopulumutsa ntchito ndizopanga zatsopano zomwe zimatsata zomwe zikuchitika.Mwachindunji, kafukufuku wopulumutsa anthu pakupanga mankhwala ophera tizilombo amatanthauza kuti ogwiritsira ntchito amatha kupulumutsa maola ndi ntchito pogwiritsira ntchito mankhwala ophera tizilombo pogwiritsa ntchito njira ndi njira zosiyanasiyana, ndiko kuti, kuphunzira momwe angagwiritsire ntchito njira zopulumutsira anthu komanso zopulumutsa ntchito mwachangu. ndi molondola ntchito mankhwala yogwira zosakaniza.Ikani kudera lomwe mukufuna kubzala mbewu.

Padziko lonse lapansi, dziko la Japan ndi dziko lomwe likutukuka kwambiri paukadaulo wopulumutsira mankhwala ophera tizilombo, ndikutsatiridwa ndi South Korea.Kupanga mapangidwe opulumutsa ntchito kwadutsa njira zitatu zofufuzira ndi chitukuko kuchokera ku ma granules kupita ku ma granules akulu, ma effervescent formulations, flowable formulations, kenako mpaka kupanga mafuta ofalitsa mafilimu, ma granules oyandama, ndi ma U granules.

M'zaka khumi zapitazi, mankhwala opulumutsa ophera tizilombo adakulanso kwambiri m'dziko langa, ndipo chitukuko ndi luso la mitundu yofananira zalimbikitsidwanso ndikugwiritsidwa ntchito mu mbewu zoimiridwa ndi minda ya paddy.Pakali pano, mankhwala ophera tizilombo omwe amapulumutsa ntchito amaphatikizapo mafuta ofalitsa mafilimu, ma granules oyandama, ma granules a U, ma microcapsules, osungunula madzi pamwamba pa madzi, ma effervescent agents (mapiritsi), granules zazikulu, granules zodzaza kwambiri, osuta fodya, nyambo, ndi zina zotero. .wachifundo. 

M'zaka zaposachedwapa, chiwerengero cha kukonzekera ntchito yopulumutsa analembetsa m'dziko langa chawonjezeka chaka ndi chaka.Pofika pa Okutobala 26, 2021, China Pesticide Information Network ikuwonetsa kuti pali zinthu 24 zolembetsedwa zamagranules akulu m'dziko langa, zinthu 10 zamafuta ofalitsa mafilimu, chinthu chimodzi cholembetsedwa chamadzi otulutsa madzi, opangira utsi 146, othandizira 262 nyambo, ndi mapiritsi a effervescent.17 Mlingo ndi 303 microcapsule kukonzekera. 

Mingde Lida, Zhongbao Lunong, Xin'an Chemical, Shaanxi Thompson, Shandong Kesaiji Nong, Chengdu Xinchaoyang, Shaanxi Xiannong, Jiangxi Zhongxun, Shandong Xianda, Hunan Dafang, Anhui Huaxing Chemical, etc. onse ali panjira iyi.mtsogoleri. 

Zomwe zimagwiritsidwa ntchito kwambiri populumutsa antchito m'minda ya paddy 

Kunena kuti kukonzekera kopulumutsa ntchito kumagwiritsidwa ntchito kwambiri, ndipo dongosolo laukadaulo ndilokhwima, akadali munda wa paddy. 

Minda ya paddy ndi mbewu zomwe zimagwiritsidwa ntchito kwambiri pokonzekera zopulumutsa ntchito kunyumba ndi kunja.Pambuyo pa chitukuko m'zaka zaposachedwa, mitundu ya mlingo wa mankhwala opulumutsa ntchito omwe amagwiritsidwa ntchito m'minda ya paddy m'dziko langa ndi mafuta ofalitsa mafilimu, ma granules oyandama ndi ma granules obalalika m'madzi (U granules).Pakati pawo, mafuta ofalitsa mafilimu ndi omwe amagwiritsidwa ntchito kwambiri.

Mafuta ofalitsa filimu ndi mawonekedwe a mlingo umene mankhwala oyambirira amasungunuka mwachindunji mu mafuta.Mwachindunji, ndi mafuta opangidwa powonjezera kufalitsa ndi kufalikira kwapadera kwa mafuta wamba.Akagwiritsidwa ntchito, amaponyedwa mwachindunji m'munda wa mpunga kuti afalikire, ndipo atatha kufalikira, amafalikira pamadzi okha kuti agwiritse ntchito.Pakali pano, zoweta mankhwala monga 4% thifur·azoxystrobin filimu kufalitsa mafuta, 8% thiazide filimu kufalitsa mafuta, 1% spirulina ethanolamine mchere filimu kufalitsa mafuta, etc., ntchito ndi akudontha, amene ndi yabwino kwambiri .Mapangidwe a mafuta otambasula filimu amaphatikizapo zosakaniza zogwira ntchito, zowonongeka, ndi zosungunulira zamafuta, ndipo zizindikiro zake zowongolera khalidwe zimaphatikizirapo zinthu zomwe zimagwiritsidwa ntchito, pH range, kuthamanga kwa pamwamba, kusagwirizana kwapakati pa nkhope, chinyezi, kufalikira kwachangu, kufalikira kwa malo, kukhazikika kwa kutentha, kusungirako kutentha.bata. 

Ma granules oyandama ndi mtundu watsopano wa mankhwala ophera tizilombo omwe amayandama molunjika pamwamba pamadzi atayikidwa m'madzi, amafalikira mwachangu pamadzi onse, kenako amasweka ndikubalalika m'madzi.zigawo zake makamaka zikuphatikizapo mankhwala yogwira zosakaniza, zoyandama chonyamulira fillers, binders, disintegrated dispersants, etc. The zikuchokera granules akuyandama zikuphatikizapo yogwira zosakaniza, chonyamulira zoyandama, ndi disintegrating dispersant, ndi zizindikiro zake ulamuliro khalidwe monga maonekedwe, kupasuka nthawi, mlingo woyandama, kufalikira. mtunda, kuchuluka kwa zigawenga, ndi kupasuka. 

Ma granules amapangidwa ndi zinthu zogwira ntchito, zonyamulira, zomangira ndi zotulutsa.Akagwiritsidwa ntchito m'minda ya paddy, ma granules amakhazikika pansi kwakanthawi, kenako ma granules amabwerera kuti ayandama.Pomaliza, chogwiritsira ntchito chimasungunuka ndikufalikira mbali zonse pamadzi.Chitukuko choyambirira chinali kukonzekera kwa cypermethrin kuti aziwongolera madzi a mpunga.Kapangidwe ka U granules kumaphatikizapo zosakaniza zogwira ntchito, zonyamulira, zomangira, ndi ma diffusing agents, ndipo zizindikiro zake zowongolera khalidwe zimaphatikizapo maonekedwe, nthawi yoyambira kuyandama, nthawi yomaliza kuyandama, mtunda wa kufalikira, kuchuluka kwa kuwonongeka, ndi kupasuka.

Malinga ndi omwe ali mkati mwamakampani, Japan ndi South Korea zalimbikitsa kugwiritsa ntchito ma granules a U ndi ma granules oyandama pamlingo waukulu, koma pali maphunziro ochepa apakhomo, ndipo palibe zinthu zokhudzana nazo zomwe zayikidwa pamsika pano.Komabe, akukhulupirira kuti padzakhala zinthu zoyandama za granule pamsika ku China posachedwa.Panthawiyo, ma granules oyandama amadzi oyandama kapena mankhwala amapiritsi a effervescent amasinthidwa motsatizana ndi mankhwala akumunda wa mpunga, zomwe zipangitsa kuti zinthu zapaddy zapakhomo zizigwiritsidwa ntchito.Alimi amapindula ndi momwe amagwiritsidwira ntchito. 

Kukonzekera kwa Microencapsulated kumakhala mpikisano wotsatira wamakampani 

Pakati pa magulu omwe alipo okonzekera kupulumutsa ntchito, kukonzekera kwa microencapsulated kwakhala cholinga chachikulu chamakampani m'zaka zaposachedwa. 

Pesticide microcapsule suspension (CS) imatanthawuza kupanga mankhwala ophera tizilombo omwe amagwiritsa ntchito zida zopangira kapena zachilengedwe za polima kupanga kachipangizo kakang'ono ka zipolopolo, kumakwirira mankhwala ophera tizilombo, ndikuyimitsa m'madzi.Zimaphatikizapo magawo awiri, chipolopolo cha kapisozi ndi kapisozi core, kapisozi core ndi yogwira pophika mankhwala ophera tizilombo, ndi kapisozi chipolopolo ndi filimu kupanga polima zinthu.Tekinoloje ya Microencapsulation idagwiritsidwa ntchito koyamba kunja, kuphatikiza mankhwala ena ophera tizilombo ndi fungicides, omwe adagonjetsa zovuta zaukadaulo komanso zamtengo wapatali, ndipo adapangidwanso mwamphamvu ku China m'zaka zaposachedwa.Malinga ndi kafukufuku wa China Pesticide Information Network, pofika pa Okutobala 26, 2021, kuchuluka kwa zinthu zokonzekera zomwe zidalembetsedwa mdziko langa zidakwana 303, ndipo zolembedwa zolembetsedwa zidaphatikizapo kuyimitsidwa kwa ma microcapsule 245, kuyimitsidwa kwa ma microcapsule 33, komanso kuyimitsidwa kwamankhwala ambewu.11 granules, 8 mankhwala microcapsule kuyimitsidwa-kuyimitsidwa, 3 microcapsule ufa, 7 microcapsule granules, 1 microcapsule, ndi 1 microcapsule kuyimitsidwa-amadzimadzi emulsion.

Zitha kuwoneka kuti kuchuluka kwa kuyimitsidwa kwa ma microcapsule omwe amalembetsedwa m'nyumba zokonzekera za microcapsule ndikokulirapo, ndipo mitundu yamitundu yolembetsedwa yamankhwala ndi yaying'ono, kotero pali malo akulu otukuka.

Liu Runfeng, mkulu wa R&D Center ya Yunfa Biological Group, adati ma microcapsules ophera tizilombo, monga momwe amapangira zachilengedwe, ali ndi ubwino wokhala ndi nthawi yayitali, chitetezo ndi kuteteza chilengedwe.Chimodzi mwa izo ndi malo ochita kafukufuku m'zaka zaposachedwa, komanso ndi malo atsopano omwe opanga apikisane nawo.Pakadali pano, kafukufuku wapakhomo pa makapisozi amakhazikika kwambiri m'mayunivesite ndi mabungwe ofufuza zasayansi, ndipo kafukufuku woyambira wazongopeka ndi wokwanira.Chifukwa pali zopinga zingapo zaukadaulo popanga kukonzekera kwa microcapsule, zosakwana 100 ndizogulitsa, ndipo ku China kulibe zokonzekera za microcapsule.Zogulitsa za makapisozi ndi mabizinesi okonzekera mankhwala okhala ndi mpikisano waukulu.

Pampikisano wowopsa wa msika, kuwonjezera pa zomwe sizingawonongeke zamakampani akale akunja m'mitima ya anthu aku China, makampani opanga zoweta monga Mingde Lida, Hailier, Lier, ndi Guangxi Tianyuan amadalira mtundu kuti athyole mzindawo.Mwa iwo, Mingde Lida adasokoneza malingaliro akuti zinthu zaku China sizili bwino ngati makampani akunja panjira iyi. 

Liu Runfeng adalengeza kuti ukadaulo wa microencapsulation ndiye mpikisano waukulu wa Mindleader.Mindleader yapanga mankhwala monga beta-cyhalothrin, metolachlor, prochloraz, ndi abamectin: Pali zinthu zopitilira 20 zomwe zatsimikizika ndipo zikuimilira kuti zilembetse m'magulu anayi akuluakulu: fungicide microcapsule series, insecticide microcapsule series, herbicide microcapsule series, ndi mbewu ❖ kuyanika microcapsule mndandanda.Mbewu zosiyanasiyana zaphimbidwa, monga mpunga, zipatso za citrus, masamba, tirigu, maapulo, chimanga, maapulo, mphesa, mtedza, etc. 

Pakadali pano, zinthu zazing'ono za Mingde Lida zomwe zalembedwa kapena zatsala pang'ono kulembedwa ku China zikuphatikiza Delica® (25% beta-cyhalothrin ndi clothianidin microcapsule suspension-suspension agent), Lishan® (45% essence Metolachlor Microcapsule Suspension), Lizao® (30% Oxadiazone·Butachlor Microcapsule Suspension), Minggong® (30% Prochloraz Microcapsule Suspension), Jinggongfu ® (23% beta-cyhalothrin microcapsule suspension), Miaowanjin® (25% clothianidin·metalaxyl·fludiosuspsuleed microcapsule suspension ), Deliang® (5 % Abamectin Microcapsule Suspension), Mingdaoshou® (25% Prochloraz·Blastamide Microcapsule Suspension), ndi zina zotero.Ndikufika kwa olembetsa akunja, zinthu za Mingde Lida za microcapsule zidzakwezedwa pang'onopang'ono ndikugwiritsidwa ntchito padziko lonse lapansi.

Polankhula za kafukufuku wam'tsogolo komanso kakulidwe ka mankhwala ophera tizilombo m'tsogolomu, Liu Runfeng adawulula kuti padzakhala mayendedwe asanu otsatirawa: ① kuchoka pang'onopang'ono mpaka kumasulidwa kolamulidwa;② zida zoteteza zachilengedwe m'malo mwa zida zopangira khoma kuti zichepetse kutulutsa kwa "microplastics" m'chilengedwe;③ kutengera kamangidwe ka Fomula yamagwiritsidwe osiyanasiyana;④ Njira zokonzekera zotetezeka komanso zosawononga chilengedwe;⑤ Njira zowunikira zasayansi.Kupititsa patsogolo kukhazikika kwazinthu zoyimitsidwa za microcapsule kudzakhala cholinga cha mabizinesi omwe akuyimiridwa ndi Mingde Lida mtsogolomo. 

Mwachidule, ndi kupititsa patsogolo mozama kwa kuchepetsa mankhwala ophera tizilombo komanso kupititsa patsogolo mphamvu, kufunikira kwa msika ndi kuthekera kwa njira zopulumutsira anthu ogwira ntchito zidzasinthidwa ndikutulutsidwa, ndipo tsogolo lake lidzakhala lopanda malire.Zachidziwikire, padzakhalanso makampani okonzekera bwino kwambiri omwe adzatsanulire munjira iyi, ndipo mpikisano udzakhala wokulirapo.Choncho, anthu m’makampaniwa akupempha makampani ophera tizilombo m’nyumba kuti apitirize kulimbikitsa kafukufuku ndi chitukuko cha mankhwala ophera tizilombo, kuonjezera ndalama zofufuza zasayansi, kufufuza kagwiritsidwe ntchito kaukadaulo pokonza mankhwala ophera tizilombo, kulimbikitsa chitukuko cha njira zopulumutsira anthu ogwira ntchito, komanso kutumikira bwino ulimi.
