Tom qab ntau tshaj li ib xyoos ntawm kev siv, "Inner Mongolia Pilot Demonstration of Water Seepage Plastic Film Dry Farming Technology" project ua los ntawm Inner Mongolia Agricultural University tau ua tiav cov txiaj ntsig. Tam sim no, ntau qhov kev tshawb fawb txog kev ua tiav tau hloov pauv thiab siv hauv qee lub nroog koom nrog hauv cheeb tsam.
Seepage mulch qhuav ua liaj ua teb tshuab yog ib qho cuab yeej siv rau hauv cov cheeb tsam ib nrab arid hauv kuv lub teb chaws los daws cov teeb meem ntawm cov pa phem dawb hauv thaj av ua liaj ua teb, siv cov peev txheej ntuj los nag, thiab txhim kho qoob loo hauv av qhuav. Qhov tseem ceeb. Xyoo 2021, Lub Tsev Haujlwm Saib Xyuas Kev Ncaj Ncees ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb thiab thev naus laus zis yuav nthuav dav thaj chaw ua qauv qhia rau 8 lub xeev thiab thaj chaw tswj hwm tus kheej suav nrog Hebei, Shanxi, Inner Mongolia, Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang thiab Xinjiang Kev Tsim Kho thiab Kev Tsim Kho Corps raws li. kev tshawb fawb thiab kev txhawb nqa ua qauv qhia tau ua nyob rau theem pib.
Kev tshawb fawb thev naus laus zis tseem ceeb ntawm kev ua liaj ua teb qhuav yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm kev tshawb fawb thiab thev naus laus zis rau kev txhawb nqa nyob deb nroog thiab kev loj hlob. Txhawm rau pab txhim kho qhov zoo thiab ua haujlwm ntawm kev ua liaj ua teb qhuav qhuav, hauv 2022, Inner Mongolia Agricultural University thiab Inner Mongolia Zhongqing Agricultural Development Co., Ltd., nrog kev txhawb nqa los ntawm Autonomous Region Science thiab Technology Department, Los ntawm kev lag luam-university- kev tshawb fawb kev koom tes, qhov project ntawm "Kev hloov pauv thiab kev siv cov kev ua tiav ntawm Seepage yas zaj duab xis thiab qhuav ua liaj ua teb cog qoob loo" yog siv. Lub phiaj xwm tau ua tiav qhov kev hloov pauv thiab siv cov cuab yeej ua ke cog qoob loo ua tiav ntawm biodegradable dej seepage mulch, kev ua liaj ua teb qhuav thiab lub qhov tshuab seeding tshuab, aiming ntawm cov teeb meem ntawm kev nyuaj rov qab ntawm yas zaj duab xis mulching, loj seem thiab ib puag ncig muaj kuab paug. Pab neeg no tau koom ua ke oat, millet thiab millet infiltration mulching zaj duab xis qhuav ua liaj ua teb hauv xyoo 2021, nrog rau cov bred "Mengnong Dayan" series ntawm oat tshiab, qhia "Baiyan" series thiab "Bayou" series thiab lwm yam tshiab oat ntau yam. . , Kev taw qhia thiab kev tshuaj xyuas ntawm cov millet tshiab xws li cov nplej daj daj thiab cov nplej dawb, thiab cov nplej tshiab xws li Xiaoxiangmi thiab Jingu No. 21 tau hloov pauv, thiab cov kev cai sib xws tau tsim los ntawm kev tsim qauv ua qauv qhia.
Raws li Liu Jinghui, tus thawj coj ntawm pawg neeg tsim khoom lag luam ntawm Inner Mongolia Demonstration Area ntawm seepage mulching technology thiab ib tug xibfwb ntawm Inner Mongolia Agricultural University: "Qhov project tau ua nyob rau hauv Jiucaizhuang, Honghe Town, Wuliang Taixiang thiab Gaomao Spring. hauv Qingshuihe County, Hohhot City. 1000 mu ntawm cov qoob loo qhuav xws li noob, taum pauv, pob kws thiab lwm yam 1,000 mu ntawm cov qoob loo qhuav nrog dej seepage biodegradable yas zaj duab xis, ib zaj duab xis thiab tsib kab ntawm micro-furrow sowing, ib zaj duab xis thiab ob kab ntawm micro-furrow sowing, seepage PE yas zaj duab xis, ib zaj duab xis, tsib-kab micro-furrow sowing thiab lwm yam technologies. Qhov kev sib piv qhia tau hais tias kev ua liaj ua teb qhuav ntawm cov yas zaj duab xis tuaj yeem txhim kho qhov tshwm sim ntawm cov qoob loo thiab cov av cov ntsiab lus ntawm cov yub, txhawb kev loj hlob ntawm cov qoob loo, thiab cov nyhuv degradation ntawm yas zaj duab xis kuj tau mus txog lub hom phiaj xav tau. Qhov tshwm sim ntawm cov noob qoob loo yog 6.25%. Cov dej-permeable yas zaj duab xis thiab cov dej-degradable yas zaj duab xis tau nce cov av cov ntsiab lus ntawm cov millet seedling theem thiab 0-40cm av txheej ntawm theem sib koom los ntawm 12.1% -87.4% thiab 7% -38% raws li, uas yog kev txhawb nqa loj ntawm cov cuab yeej tom ntej. Daim ntawv thov tso lub hauv paus. "
