1. Taw qhia

Aluminium phosphide feem ntau yog siv los ua cov tshuaj tua kab dav dav, uas feem ntau yog siv los fumigate thiab tua cov kab tsuag ntawm cov khoom, ntau yam kab tsuag hauv qhov chaw, cov qoob loo khaws cov kab tsuag, cov noob qoob loo khaws cov kab tsuag, cov nas sab nraum zoov hauv qhov tsua, thiab lwm yam.

1. Daim ntawv thov

Nyob rau hauv lub tsev khaws khoom kaw los yog ntim, nws tuaj yeem tua tau txhua yam ntawm cov kab tsuag thiab nas nyob hauv lub tsev khaws khoom.Yog tias muaj kab tsuag hauv granary, nws kuj tuaj yeem raug tua zoo.Phosphine tuaj yeem siv tau thaum cov kab tsuag, ntshauv, cov khaub ncaws tawv thiab cov kab hauv tsev thiab cov khw muag khoom noj, lossis tsis txhob muaj kab tsuag.Thaum siv nyob rau hauv kaw tsev cog khoom, iav tsev thiab yas tsev cog khoom, nws muaj peev xwm ncaj qha tua tag nrho cov underground thiab saum toj no kab tsuag thiab nas, thiab nkag mus rau hauv cov nroj tsuag kom tua boring kab thiab paus nematodes.Cov hnab yas kaw thiab cov tsev cog khoom nrog cov tuab tuab tuaj yeem siv los cuam tshuam nrog qhib paj hauv paus thiab xa tawm paj paj, thiab tua nematodes hauv av thiab hauv cov nroj tsuag thiab ntau yam kab tsuag ntawm cov nroj tsuag.

Dosage thiab siv
1. 3 ~ 8 daim ib tuj ntawm khaws cia nplej lossis khoom;2 ~ 5 pieces ib cubic meter;1-4 pieces ib cubic meter ntawm qhov chaw fumigation.

2. Tom qab steaming, qhib daim ntaub los yog yas zaj duab xis, qhib lub qhov rooj thiab qhov rais los yog lub qhov rooj qhov cua, thiab siv tej yam ntuj tso los yog mechanical qhov cua kom tag nrho disperse cov pa thiab tso pa tawm cov pa phem.

3. Thaum nkag mus rau hauv lub tsev rau khoom, siv cov ntawv xeem uas tau ntim rau hauv 5% ~ 10% silver nitrate tov los kuaj cov pa roj.Tsuas yog thaum tsis muaj phosphine roj tuaj yeem nkag mus rau hauv lub tsev khaws khoom.

4. Lub sijhawm fumigation nyob ntawm qhov kub thiab av noo.Fumigation tsis haum hauv qab 5℃;5℃~ 9℃tsis pub tsawg tshaj 14 hnub;10℃~ 16℃tsis pub tsawg tshaj 7 hnub;16℃~ 25℃tsis pub tsawg tshaj 4 hnub;Tsis pub tsawg tshaj 3 hnub saum 25℃.Haus luam yeeb thiab tua voles, 1 ~ 2 ntsiav tshuaj ib lub qhov nas.

1. Nta thiab cov nyhuv

1. Kev sib cuag ncaj qha nrog cov reagent yog nruj me ntsis txwv.

2. Kev siv tus neeg sawv cev no yuav tsum ua raws li cov kev cai cuam tshuam thiab kev nyab xeeb ntawm aluminium phosphide fumigation.Fumigation ntawm tus neeg sawv cev no yuav tsum tau coj los ntawm cov kws tshaj lij lossis cov neeg ua haujlwm paub txog.Nws yog txwv tsis pub ua haujlwm ib leeg.Nws yuav tsum tau nqa tawm nyob rau hauv tshav ntuj huab cua, tsis yog hmo ntuj.

3. Lub thoob tshuaj yuav tsum qhib sab nraum zoov.Ib txoj kab ceeb toom kev phom sij yuav tsum tau teem ib ncig ntawm qhov chaw fumigation.Lub qhov muag thiab lub ntsej muag yuav tsum tsis txhob ncaj nraim rau ntawm lub qhov ncauj.Cov tshuaj yuav tsum tau muab tshuaj rau 24 teev, thiab ib tus neeg tshwj xeeb yuav tsum tau teem sijhawm los xyuas seb puas muaj cua nkag thiab hluav taws.

4. Phosphine yog corrosive heev rau tooj liab.Cov khoom siv tooj liab xws li hluav taws xob hloov hluav taws xob thiab lub teeb lub hau yog coated nrog cov roj cav lossis kaw thiab tiv thaiv nrog cov yeeb yaj kiab yas.Cov khoom siv hlau hauv qhov chaw fumigation tuaj yeem raug tshem tawm ib ntus.

5. Tom qab dispersing cov roj, sau cov seem ntawm lub hnab tshuaj tag nrho.Nyob rau hauv qhov chaw qhib nyob deb ntawm qhov chaw nyob, muab lub hnab seem rau hauv lub thoob hlau uas muaj dej thiab tsau nws tag nrho, kom cov seem ntawm txhuas phosphide tuaj yeem decomposed tag nrho (txog thaum tsis muaj npuas ntawm cov kua dej).Qhov tsis zoo slag slurry tuaj yeem muab pov tseg rau hauv qhov chaw pov tseg slag pov tseg uas tau tso cai los ntawm ib puag ncig tiv thaiv kev tswj hwm.

6. Kev kho mob ntawm phosphine absorbent hnab: tom qab lub hnab ntim tau yooj yim yog unpacked, ib lub hnab me me absorbent txuas rau lub hnab yuav tsum tau sau thiab muab faus rau hauv lub tshav pob.

7. Cov thawv ntim khoom siv yuav tsum tsis txhob siv rau lwm lub hom phiaj thiab yuav tsum muab pov tseg rau lub sijhawm.

8. Cov khoom no yog tshuaj lom rau muv, ntses thiab silkworm.Tsis txhob cuam tshuam rau thaj tsam ib puag ncig thaum thov.Nws yog txwv tsis pub siv nyob rau hauv silkworm chav.

9. Thaum siv tshuaj, hnav lub npog ntsej muag uas tsim nyog, hnav khaub ncaws ua haujlwm thiab hnab looj tes tshwj xeeb.Tsis haus luam yeeb lossis noj.Ntxuav tes thiab ntsej muag lossis da dej tom qab thov.

1. Kev khaws cia thiab kev thauj mus los

Nyob rau hauv cov txheej txheem ntawm kev thauj khoom, tshem tawm thiab kev thauj mus los, cov khoom npaj yuav tsum tau ua tib zoo saib xyuas, thiab yuav tsum nruj me ntsis tiv thaiv los ntawm cov av noo, kub lossis tshav ntuj.Cov khoom no yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo ventilated.Nws yuav tsum tau muab cia rau hauv qhov chaw kaw.Cia kom deb ntawm cov tsiaj nyeg thiab nqaij qaib thiab khaws cia rau hauv kev saib xyuas tshwj xeeb.Cov foob pob hluav taws raug txwv nruj rau hauv lub tsev rau khoom.Thaum lub sijhawm khaws cia, thaum siv tshuaj tua hluav taws, tsis txhob siv dej los yog acidic tshuaj tua hluav taws.Cov pa roj carbon dioxide lossis cov xuab zeb qhuav tuaj yeem siv los tua hluav taws.Khaws kom deb ntawm menyuam yaus thiab tsis txhob khaws thiab thauj khoom noj, dej haus, nplej, pub thiab lwm yam khoom tib lub sijhawm.
