Thawj txheej txheem ntawm Radiata Pine ua thiab txheej kab
Aug 12, 2022
Muaj tag nrho ntawm 7 txheej txheem nyob rau hauv cov txheej txheem pem hauv ntej ntawmradiata Pine uathiab txheej kab. Cov hauv qab no yog cov ncauj lus kom ntxaws txog cov txheej txheem 7 no.
1. Log slicing: Lub cav yog hlais, tev, thiab cov khoom puas (roj ntoo) raug xaiv, uas yuav tsum tau txiav raws li qhov loj ntawm qhov kev txiav txim.
2. Kev ziab: Muab cov ntoo ntoo rau hauv lub thawv kom qhuav kom lub cev qhuav dej thiab degreasing, thiab kho qhov kub thiab txias raws li qhov hloov ntawm cov dej noo ntawm cov ntoo. Qhov kub thiab txias yuav qis dua, thiab feem ntau nws yuav siv li 7 hnub kom qhuav. (Cov dej noo nce mus txog 6 feem pua --8 feem pua , thiab nws tuaj yeem tawm ntawm lub qhov cub.)
3. Kev txuag kev noj qab haus huv: Cov ntoo yog zoo huv si thiab sib npaug rau hauv lub qhov cua thiab qhuav carport rau natural resurgence. Lub sijhawm tiv thaiv kev noj qab haus huv feem ntau yog kwv yees li 20-30 hnub. Lub sijhawm txuag kev noj qab haus huv muaj qee yam kev sib raug zoo nrog cov khoom siv thiab lub caij nyoog ntawm cov ntoo. (Thaum kawg ntawm kev txuag kev noj qab haus huv) Tom qab cov dej noo yog li 8 feem pua -13 feem pua .)
4. Kev xaiv cov khoom siv: txiav cov ntoo noj qab haus huv raws li qhov kev txiav txim loj, txiav tawm cov tawv ntoo, lub plawv rotten, ntoo rotten, tawg cov khoom puas, nti, thiab roj.
5. Kev sib txuas ntiv tes: Txhuam ob qhov kawg ntawm cov ntoo uas tau xaiv (daim duab), txhuam ib kawg ntawm cov zuag nrog cov kua nplaum sib npaug, thiab tom qab ntawd ntiv tes koom nrog lwm cov zuag uas tsis tau txhuam nrog cov kua nplaum.
6. Splicing: Siv lub tshuab kom plam sab ntawm lub rooj tsavxwm, thiab nws yuav tsum ua kom tiaj tus thiab du, thiab tom qab ntawd muab cov kua nplaum sib npaug ntawm sab, thiab sib txuas rau sab.
7. Kev sib sau: Cov ntoo strips tom qab ntiv tes sib koom ua ke yog tsim los ntawm lub tshuab tsim. Cov duab ntawm txhua yam khoom sib txawv, thiab cov duab ntawm cov khoom tsim kuj yuav txawv. Koj yuav tsum tau ua tib zoo saib xyuas seb cov khoom npaj yog tib yam li daim duab xaj los ntawm tus neeg siv khoom. (Qhov loj ntawm cov khoom tsim dawb embryo yuav tsum me dua cov khoom tiav los ntawm 0.4-0.5MM)
