Yuav Ua Li Cas Txiav Txim Qhov Zoo Ntawm Cov Dej Dej Siv Dej

Drip irrigation siv yog cov cuab yeej ua liaj ua teb uas siv los ntawm cov neeg ua liaj ua teb thiab ua lub luag haujlwm tseem ceeb hauv kev ua liaj ua teb. Txawm li cas los xij, nyob rau xyoo tas los no, ntau lub tuam txhab me me - nplai tau tshwm sim hauv kev ua lag luam, thiab qee cov tuam txhab lag luam tsis tau ua raws li cov kev xav tau ntawm cov txheej txheem, thiab tsis ua raws li cov qauv hauv lub tebchaws, ua rau muaj qhov zoo. ntawm cov khoom siv dropper tsim tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Yog li ntawd, cov neeg siv yuav tsum paub qee yam kev txawj thaum yuav cov khoom siv no, thiab yuav tsum muaj peev xwm paub qhov txawv ntawm cov khoom zoo thiab tsis zoo. Nov yog qee cov lus qhia qhia rau koj:

1. Txheeb xyuas tias cov drip irrigation tsis muaj daim ntawv pov thawj thiab cov lus qhia tshwj xeeb thiab cov ntawv cim qauv.

2. Choose a good product through "Three points of external inspection, seven items of index inspection":

Saib peb lub ntsiab lus:

(1) Xim, feem ntau yog xim dub, zoo ib yam;

(2) Saib ntawm qhov chaw, nws yog du thiab tiaj tus, tsis muaj npuas, dai kab, nruj blocks, impurities, thiab lwm yam .;

(3) Saib ntawm lub labyrinth khiav, molding yog tag nrho thiab tsis muaj deformation.

Xya yam khoom xeem:

(1) Dripper txaus tus nqi: Hauv peb cheeb tsam, tus dripper txaus tus nqi yuav tsum yog 1.8-2.6L / h. Yog hais tias tus dripper txaus tus nqi yog loj, nws yuav ua rau ib tug loj npaum li cas ntawm cov dej siv;

(2) Dripper spacing: feem ntau 300-400mm yog qhov tsim nyog, thiab nws yog ib qho nyuaj rau lav qhov uniformity ntawm cov kab ke dav dav nrog qhov sib nrug hauv qab 200mm;

(3) Flow Performance index: labyrinth drip irrigation siv feem ntau yog 0.5-0.6, qhov me dua qhov zoo;

(4) Flow uniformity coefficient (CV): tsawg dua 5 feem pua ​​yog tsim nyog;

(5) Kev tiv thaiv-kev ua haujlwm txhaws: Kev tiv thaiv-kev ua haujlwm txhaws feem ntau yog nyob ntawm cov qauv ntws ntws, qhov loj thiab qhov nrawm nrawm hauv cov dej ntws ntawm cov kav dej. Lub zigzag ntws channel qauv zoo dua li Great Wall hom labyrinth ntws channel;

(6) Tensile zog: Tensile zog feem ntau muaj feem xyuam rau qhov piv ntawm cov ntaub ntawv tshiab. Cov ntaub ntawv tshiab dua, qhov zoo dua qhov tensile zog. Cov khoom tensile dav dav ntawm drip irrigation tapes uas siv cov khoom siv rov ua dua yog feem ntau tsis tsim nyog;

(7) Kev tiv thaiv- kev laus kev ua haujlwm yog hais txog lub sijhawm los xyuas kom meej qhov kev siv ntawm cov dej drip irrigation siv, feem ntau yog saib seb puas muaj cov pa roj carbon dub thiab cov tshuaj antioxidants ntxiv.

Thaum qhov kev yuav khoom tiag tiag, peb tuaj yeem paub qhov txawv ntawm nws qhov zoo ntawm qhov pom thiab qhov ntsuas ntawm txoj siv drip irrigation, thiab sim yuav cov khoom siv dripper siab - zoo thiab pheej yig.
