Tom qab ntau tshaj ib xyoos ntawm kev siv, qhov project "Inner Mongolia Pilot Demonstration of Water Seepage Plastic Film Dry Farming Technology" uas tau ua los ntawm Inner Mongolia Agricultural University tau ua tiav cov txiaj ntsig theem. Tam sim no, ntau qhov kev tshawb fawb tau hloov pauv thiab siv rau hauv qee lub nroog koom tes hauv cheeb tsam.
Kev siv tshuab ua liaj ua teb qhuav siv cov av qhuav yog ib txoj kev siv tshuab uas feem ntau siv rau hauv thaj chaw qhuav hauv kuv lub tebchaws los daws qhov teeb meem ntawm kev ua qias tuaj dawb hauv thaj chaw ua liaj ua teb, siv cov peev txheej ntuj tsim kom zoo, thiab txhim kho cov qoob loo hauv thaj av qhuav. Tseem ceeb heev. Xyoo 2021, Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb thiab Tshuab yuav nthuav dav thaj chaw ua qauv qhia mus rau 8 lub xeev thiab thaj chaw ywj pheej suav nrog Hebei, Shanxi, Inner Mongolia, Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang thiab Xinjiang Production thiab Construction Corps raws li kev tshawb fawb thiab kev txhawb nqa kev ua haujlwm ua thaum ntxov.
Kev tshawb fawb txog thev naus laus zis tseem ceeb ntawm kev ua liaj ua teb qhuav yog ib qho tseem ceeb ntawm kev txhawb nqa kev tshawb fawb thiab thev naus laus zis rau kev txhim kho thiab kev txhim kho hauv nroog. Txhawm rau pab txhim kho qhov zoo thiab kev ua haujlwm ntawm kev ua liaj ua teb qhuav, xyoo 2022, Inner Mongolia Agricultural University thiab Inner Mongolia Zhongqing Agricultural Development Co., Ltd., nrog kev txhawb nqa ntawm Autonomous Region Science thiab Technology Department, Los ntawm kev koom tes ntawm kev lag luam-tsev kawm ntawv-kev tshawb fawb, qhov project ntawm "Kev Hloov Pauv thiab Kev Siv Cov Txuj Ci ntawm Cov Yeeb Yaj Kiab Yas Seepage thiab Kev Ua Liaj Ua Teb Qhuav" tau siv. Qhov project tau ua tiav kev hloov pauv thiab kev siv cov txheej txheem cog qoob loo ua ke ntawm cov dej biodegradable seepage mulch, kev ua liaj ua teb qhuav thiab cov tshuab noob qhov, tsom mus rau cov teeb meem ntawm kev rov qab nyuaj ntawm cov yeeb yaj kiab yas mulching, cov khoom seem ntau thiab kev ua qias tuaj ib puag ncig. Pab pawg project tau koom ua ke oat, millet thiab millet infiltration mulching zaj duab xis qhuav ua liaj ua teb hauv xyoo 2021, nrog rau cov "Mengnong Dayan" series ntawm cov hom oat tshiab, cov "Baiyan" series thiab "Bayou" series thiab lwm yam hom oat tshiab. , Kev qhia thiab kev tshuaj ntsuam ntawm cov noob millet tshiab xws li noob millet daj thiab noob millet dawb, thiab cov noob millet tshiab xws li Xiaoxiangmi thiab Jingu No. 21 tau raug hloov pauv, thiab cov kev cai lij choj sib xws tau tsim los ntawm kev tsim cov hauv paus ua qauv qhia.
Raws li Liu Jinghui, tus thawj coj ntawm pawg neeg lag luam ntawm Inner Mongolia Demonstration Area ntawm seepage mulching technology thiab ib tug xibfwb ntawm Inner Mongolia Agricultural University: "Qhov project tau ua tiav 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 thev naus laus zis. Qhov kev xeem sib piv qhia tau hais tias cov thev naus laus zis ua liaj ua teb qhuav ntawm seepage yas zaj duab xis tuaj yeem txhim kho qhov tshwm sim ntawm cov qoob loo thiab cov dej hauv av ntawm theem noob, 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. Tus nqi tshwm sim ntawm cov noob millet yog 6.25%. Cov yas zaj duab xis dej-permeable thiab cov yas zaj duab xis dej-degradable tau ua rau cov av ntau dua Cov dej ntawm cov noob millet thiab cov av txheej 0-40cm ntawm theem sib koom ua ke los ntawm 12.1% -87.4% thiab 7% -38% feem, uas yog kev txhawb nqa loj ntawm cov thev naus laus zis tom ntej. Daim ntawv thov tso lub hauv paus.
