I. Txog tooj liab hydroxide
Tooj liab hydroxide, raws li cov khoom fungicide, yog thawj zaug tsim los ntawm Asmeskas lub tuam txhab hauv xyoo 1968, thiab muaj keeb kwm ntau dua 50 xyoo rau hnub tim. Nws yog ib qho ntawm cov feem ntau xa mus rau Copper {{}}}} {{{{{{}} specgrum tooj liab fungicide.
Lub tshuab ntawm kev ua ntawm tooj liab hydroxide yog tus tooj liab ions yog nqus tau los ntawm cov kab mob ntawm cov kab mob pathogenic. Thaum tau sau rau qee qhov kev xav tau, lawv coagulate cov protein hauv spore cov kab mob ntawm cov kab mob pathogenic ntawm cov kab mob spore thiab ua tiav cov nyhuv bactericidal. Nyob rau tib lub sijhawm, tooj liab tuaj yeem ua rau qee cov tshuaj enzyme hauv cov kab mob ntawm cov kab mob pathogenic, thiab yog li inhibit thiab tua cov kab mob. Qhov no yog dab tsi peb feem ntau xa mus rau ntau - Cov nyhuv ntawm cov nyhuv.
Ii. Cov yam ntxwv ntawm Copper Hydroxide
1. Hist daim ntawv thov ntau ntau. Tooj liab hydroxide tuaj yeem siv rau ntau cov qoob loo xws li dib, txiv lws suav, kua txob, qos yaj ywm, citrus, thiab mango. Nws yog tsuas yog siv los tswj ntau yam kab mob thiab cov kab mob fungal, suav nrog dib qaib angular nplooj ntoos thiab downy mildew; Lws suav so rot, canker, blight thaum ntxov, thiab blight lig; kua txob dawb nqaij, scab, thiab bilterial wilt; Lub txiv kab ntxwv txiv hmab txiv ntoo butter blotch, anthracnose, thiab vine blight; Luam yeeb phom sij; Thiab txiv hmab downy mildew thiab anthracnose. Ntxiv rau kev ua kom txau foliar, tooj liab hydroxide kuj tseem siv tau rau noob tau tua cov kab mob nqa los ntawm cov noob.
2. Raws li peb tau hais ua ntej hauv lub tshuab kev ua ntawm tooj liab hydroxide, nws yog mult {1} {ua yeeb yam fungicide. Yog li ntawd, nws tsis yooj yim los tsim cov yeeb tshuaj tsis kam muaj kev siv tshuaj tas li, uas yog vim li cas hom kev lom zem no tau nrov tau ntev.
3.Cov duab hydroxide yog cov tshuaj lom neeg tiv thaiv. Thaum siv ua ntej lossis thaum pib ntawm cov kab mob qoob loo thaum ntxov, nws tuaj yeem tsim cov teebmeem tam sim ntawd. Txawm li cas los xij, txij li tooj liab hydroxide tsis muaj qhov ua haujlwm tsis zoo, tsis yog nws yog qhov zoo tshaj plaws los ntawm cov fungicating los txhim kho cov nyhuv kev tswj hwm. Thaum siv ib leeg, nws raug nquahu kom thov nws txuas ntxiv ntau dua ob zaug ntawm cov sij hawm ntawm 7-10 hnub, nyob ntawm qhov xwm txheej. Yog tias siv nyob rau theem lig ntawm tus kab mob, cov kev tswj hwm kev tswj hwm yuav tsis zoo tagnrho. Tsis tas li ntawd, cov dej nag tom qab daim ntawv thov yuav tseem cuam tshuam rau kev tswj hwm kev tswj hwm.
III. Daim Ntawv Thov thiab Kev Ua Si
1. Raws li hom tooj liab -}} hydroxide, thiab sib xyaw nrog lwm cov tshuaj tua kab yuav tsum zam kom ntau li ntau tau. Tshwj xeeb, nws yuav tsum tsis txhob sib xyaw nrog cov muaj zog acids, thiab lwm yam chiv, calcium sulfizers, magnes}}} aluminium lossis ntau tus neeg tuaj thiab cov neeg nkag. Rau thawj {-} cov neeg siv lub sijhawm, nws raug nquahu los sab laj cov neeg uas tau siv nws ua ntej lossis ua kev ntsuas me me}.
2. Rau qee cov qoob loo rhiab rau tooj liab, xws li txiv duaj, plums, apricots, cherries, thiab lwm yam, tooj liab hydroxide yuav tsum tsis siv. Thaum tswj cov kab mob ntawm lwm cov qoob loo, kom nws nyob deb ntawm cov qoob loo rhiab li sai tau. Tooj liab hydroxide yuav tsum tsis txhob siv rau ntawm cov txiv hmab txiv ntoo zoo li txiv hmab txiv ntoo thiab pears thaum lub sijhawm tawg paj. Thaum siv nws ntawm cov citrus, lub siab yuav tsum tau tswj hwm; Txwv tsis pub, phytotoxicity feem ntau yuav tshwm sim.
3.Thaum cov tooj liab hydroxide sib xyaw nrog lwm cov tshuaj tua kab lossis cov foliar fertilizers, nws yog qhov zoo tshaj plaws los kuaj cov dilution. Ua ntej, maj mam ntxiv tooj liab hydroxide rau lub thawv ntim nrog dej tshuaj tua kab lossis tshuaj foliar fertilizers kom sib xyaw thaum nplawm. Zam kev ua kua ncaj qha rau hauv lub taub lim hlau ntawm cov tshuaj tsuag dej ntawm cov tshuaj txau lossis mus rau hauv cov tshuaj txau lossis lwm yam nws yooj yim los ua cov qog ua tshuaj tua kab. Txau yuav tsum tau zam rau hauv qhov kub; Thaum qhov kub tau siab dua 35 degree, siv yuav tsum tau raug tshem tawm. Cov tshuaj tsuag thiab cov thoob uas tau siv rau kev txau tooj liab hydrocide yuav tsum tau ntxuav hauv lub sijhawm tom qab siv, thiab nws yog qhov zoo tshaj plaws los yaug lawv ua ntej rov siv dua.
