Kodi nsalu za PP spunbond zosalukidwa zimagwira ntchito yanji pazaulimi?

PP spunbond sanali nsalu nsaluzimachokera ku chitetezo cha chilengedwe, ili ndi makhalidwe a degradability, UV kukana ndi mpweya wabwino permeability.

Basic ntchito zaPP spunbond yopanda nsalumulch:

1. Kutentha ndi kutentha kumalimbikitsa kuwonongeka ndi kumasulidwa kwa michere ya nthaka.

2. Moisturizing, kusintha mlingo wa kupulumuka.Kupatula ulimi wothirira, gwero lalikulu la chinyezi m'nthaka ndi mvula.The mulching filimu akhoza bwino kuletsa kuchepetsa nthaka madzi nthunzi, ndi imfa ndi wosakwiya;ndipo madontho amadzi amapangidwa mufilimuyo kenako amagwera pamtunda, kuchepetsa kutaya kwa madzi a nthaka ndikuchita nawo ntchito yosunga madzi a nthaka.Kumbali ina, mulch ukhozanso kulepheretsa madzi a mvula kulowa m'mphepete mwa mvula pamene mvula yachuluka, zomwe zingathandize kuti madzi asapitirire.

3. Limbikitsani kukula ndi chitukuko.Kugwiritsa ntchito mulch wa filimu ya pulasitiki kumawonjezera kutentha ndi chinyezi cha nthaka, zomwe zimathandizira kukula koyambirira komanso kukula mwachangu komanso kulimbikitsa kukula ndi kukula kwa mbewu.Nthawi ya kukula kwa filimuyi imafupikitsidwa pafupifupi sabata imodzi kuposa momwe zimakhalira popanda filimu.

4. Chepetsani kuwonongeka kwa udzu ndi nsabwe za m'masamba.Pulasitiki filimu mulching zingalepheretse kukula kwa namsongole.Nthawi zambiri, namsongole wokhala ndi mulching filimu amachepetsedwa ndi gawo limodzi mwa magawo atatu kuposa omwe alibe mulching.Mukaphatikizidwa ndi mankhwala ophera udzu, zotsatira za kuwononga udzu zimawonekera kwambiri.Pambuyo kupopera mankhwala a herbicides, namsongole wophimbidwa ndi filimuyo amatha kuchepetsedwa ndi 89.4-94.8% poyerekeza ndi namsongole popanda filimuyo.Filimu ya mulch imakhala ndi kuwala kowunikira, ndipo imathanso kuthamangitsa nsabwe za m'masamba pang'ono, kulepheretsa kuswana ndi kubereka kwa nsabwe za m'masamba, komanso kuchepetsa kuwonongeka ndi kufalitsa matenda.

Chifukwa chake, kuphatikiza ndi lingaliro lachitukuko la sayansi la chitetezo cha chilengedwe chobiriwira, kupanga kwenikweni kwa mbewu, zabwino ndi zovuta zimapewedwa, ndipo ukadaulo wopanga filimu wa mulching umapangidwa kuti ugwiritse ntchito mokwanira udindo wa mulching filimu ndikuchepetsa kuipitsidwa kwa chilengedwe. .
