(Ububanzi bereferensi yesicelo 'ukusetshenziswa komkhiqizo')
① Ukwakheka, uhlamvu nokuqukethwe kwezakhi kuyafana, ukukhishwa kwezakhi kanye nemodi yokumuncwa kuyefana, futhi okuqukethwe kwamanzi, ubulukhuni, okuqukethwe kothuli kanye nokuthutha kanye nokumelana nesitoreji kwezinhlayiya kuhlukile.
② Izinga lokuqedwa, izinga lokukhululwa kwezakhi kanye nezinga likamanyolo wezinhlayiya kuhlukile, futhi izinga lokuqedwa kwezinhlayiya ezincane liyashesha futhi umphumela uyashesha; Ukuqedwa kwezinhlayiya ezinkulu kuhamba kancane futhi isikhathi sokuvundisa side.
③ Okuqukethwe kwe-urea biuret enkulu kuphansi kunezinhlayiya ezincane, ezisetshenziswa njengomanyolo oyisisekelo, noma izinhlayiya ezinkulu zisetshenziselwa ukukhiqizwa komanyolo ohlanganisiwe. Ukufaka i-topdressing, i-urea encane ye-granular isetshenziselwa ukufafaza kwamaqabunga, ukufaka imbobo, ukufaka umsele kanye nokuvundiswa kwe-strip, kanye nokuxutshwa kwamanzi.
④ I-urea enezinhlayiyana ezinkulu inothuli oluphansi uma iqhathaniswa nezinhlayiyana ezincane ze-urea, amandla acindezelayo aphezulu, uketshezi oluhle, ingathuthwa ngobuningi, akulula ukuphuka nokuphekwa, futhi ifanele ukuvundiswa ngomshini.
I-EVERBRIGHT® 'izophinda ihlinzeke ngendlela oyifisayo :okuqukethwe/ubumhlophe/usayizi wezinhlayiya/PHvalue/umbala/isitayela sokupakisha/ ukucaciswa kwephakheji neminye imikhiqizo eqondene nezimo zakho zokusebenzisa, futhi ikunikeze amasampula amahhala.

Ukusetshenziswa komkhiqizo
Ukulawula ukuvundisa
[Ukulungiswa kwenani lembali] Ukuze unqobe unyaka omkhulu noma omncane wensimu yama-apula, ukufafaza isixazululo se-urea esingu-0.5% ebusweni beqabunga emasontweni angama-5-6 ngemuva kokuqhakaza (isikhathi esibucayi sokuhlukaniswa kwezimbali ze-apula, ukukhula kwamahlumela amasha kuhamba kancane noma kuyama, futhi okuqukethwe kwe-nitrogen emaqabunga kubonisa ukwehla), ukufafaza kabili ngokulandelana, kungakhuphula okuqukethwe kwe-nitrogen celerate, amaqabunga amasha ahlumayo. umehluko, futhi wenze inani lembali lonyaka omkhulu lifanele.
[Flower and fruit thinning] Izitho zezimbali zepentshisi zizwela kakhulu ku-urea, kodwa ukusabela kuhamba kancane, ngakho-ke i-peach yangaphandle ngokuhlolwa kwe-urea, imiphumela ibonisa ukuthi imbali yepentshisi ne-nectarine nezithelo zokunciphisa, zidinga ukuhlushwa okukhulu (7.4%) ukukhombisa imiphumela emihle, ukuhlushwa okulungile kakhulu ku-8% -12%, amasonto angu-1-2 emva kokufafaza, ukufeza inhloso yokunciphisa imbali nezithelo.
[Ukukhiqizwa kwembewu yelayisi] Kubuchwepheshe bokukhiqiza imbewu yerayisi eyi-hybrid, ukuze kuthuthukiswe izinga lokuphuma kwabazali, ukuze kwandiswe inani lokukhiqizwa kwembewu yerayisi eliyingxube noma inani lokuzala lemigqa oyinyumba, ukuhlolwa kwenziwa nge-urea esikhundleni se-gibberellin, kanye nokusetshenziswa kwe-urea engu-1.5% kuya ku-2% esigabeni sokukhulelwa kanye nesigaba sokuqala sendlebe (ukukhethwa kwendlebe okungama-20%) kanye nomphumela ofanayo wokuzala ukwandisa ukuphakama kwesitshalo.
[Ukulawula izinambuzane] With urea, ukuwasha powder, amanzi 4:1:400, ngemva ukuxuba, kungavimbela izihlahla zezithelo, imifino, ukotini aphid, izicabucabu abomvu, izinambuzane iklabishi nezinye izinambuzane, umphumela insecticidal ezingaphezu kuka-90%. [Umanyolo wensimbi we-Urea] I-Urea yakha insimbi e-chelated ene-Fe2+ ngendlela eyinkimbinkimbi. Lolu hlobo lukamanyolo we-iron ophilayo lunezindleko eziphansi kanye nomphumela omuhle ekuvimbeleni ukuntuleka kwensimbi nokulahlekelwa okuluhlaza. Umphumela wokulawula we-chlorosis ungcono kunalowo we-0.3% ye-ferrous sulfate.
Ukuphrinta kwendwangu nokudaya
① Ingasetshenziswa njengenani elikhulu le-melamine, i-urea-formaldehyde resin, i-hydrazine hydrate, i-tetracycline, i-phenobarbital, i-caffeine, i-VAT ensundu BR, i-phthalocyanine B, i-phthalocyanine Bx, i-monosodium glutamate neminye imikhiqizo yokukhiqiza izinto zokusetshenziswa.
② Inomthelela okhanyayo ekupholiseni amakhemikhali ensimbi nensimbi engagqwali, futhi isetshenziswa njenge-corrosion inhibitor ekuqoqweni kwensimbi, futhi isetshenziselwa ukulungisa uketshezi lwe-palladium.
③ Embonini, iphinde isetshenziswe njengento eluhlaza ekwenzeni ama-urea-formaldehyde resins, polyurethanes kanye ne-melamine-formaldehyde resins.
④I-ejenti yokunciphisa ekhethiwe yokukhishwa kwegesi ekhishwayo evuthayo, kanye ne-automotive urea, eyakhiwe ngo-32.5% we-high-purity urea kanye no-67.5% wamanzi akhishiwe.
⑤ Ukuhlukanisa i-wax kapharafini (ngoba i-urea ingakha ama-clathrates), izinto eziphikisayo, izingxenye zikaphethiloli wenjini yokuvikela imvelo, izingxenye zemikhiqizo yamazinyo amhlophe, umanyolo wamakhemikhali, izinto ezisizayo ezibalulekile zokudaya nokuphrinta.
⑥ Imboni yendwangu iyi-ejenti ehle kakhulu yokuncibilikisa udayi/i-hygroscopic/i-viscose fiber enwebekayo, i-ejenti eqeda inhlaka, inokusetshenziswa okubanzi. Ukuqhathaniswa kwezakhiwo ze-hygroscopic ze-urea namanye ama-hygroscopic embonini yendwangu: isilinganiso nesisindo sayo.
Ibanga lezimonyo (isithako esithambisayo)
I-Dermatology isebenzisa ama-agent athile aqukethe i-urea ukwandisa umswakama wesikhumba. Ukugqoka okuvaliwe okusetshenziselwa izinzipho ezingasuswanga ngokuhlinzwa kuqukethe u-40% we-urea. I-Urea iyisithako esihle esithambisayo, ikhona ku-cuticle yesikhumba, iyisici esiyinhloko se-NMF sesikhumba esithambisa isikhumba.
