高標(biāo)準(zhǔn)農(nóng)田一般是指田塊平整、集中連片、設(shè)施完善、節(jié)水高效、農(nóng)電配套、宜機(jī)作業(yè)、土壤肥沃、生態(tài)友好、抗災(zāi)能力強(qiáng),且能與現(xiàn)代農(nóng)業(yè)生產(chǎn)和經(jīng)營(yíng)方式相適應(yīng)的旱澇保收、穩(wěn)產(chǎn)高產(chǎn)的耕地。在高標(biāo)準(zhǔn)農(nóng)田建設(shè)過程中,通過建設(shè)改造農(nóng)田基礎(chǔ)設(shè)施、整治土地、改良土壤等措施,形成“田成方、林成網(wǎng)、渠相連、路相通、旱能澆、澇能排、產(chǎn)量高\(yùn)"的格局,努力提高糧食產(chǎn)能、改善土壤質(zhì)量、建設(shè)生態(tài)友好型的高質(zhì)量耕地,減少農(nóng)業(yè)面源污染,降低碳排放等農(nóng)業(yè)非期望產(chǎn)出,提高農(nóng)業(yè)生產(chǎn)能力及產(chǎn)值等期望產(chǎn)出[1-2]。高標(biāo)準(zhǔn)農(nóng)田示范區(qū)是在前期高標(biāo)準(zhǔn)農(nóng)田建設(shè)經(jīng)驗(yàn)的基礎(chǔ)上,進(jìn)一步建設(shè)高標(biāo)準(zhǔn)農(nóng)田的升級(jí)版,其目的在于提升耕地地力、提高農(nóng)業(yè)灌溉效率、改善農(nóng)田生態(tài)環(huán)境等,達(dá)到全方位夯實(shí)糧食穩(wěn)產(chǎn)增產(chǎn)根基,落實(shí)“藏糧于地、藏糧于技\"戰(zhàn)略目的,發(fā)展新時(shí)代農(nóng)業(yè)領(lǐng)域新質(zhì)生產(chǎn)力,實(shí)現(xiàn)農(nóng)業(yè)的可持續(xù)發(fā)展[3-5]。河南是全國(guó)重要的農(nóng)業(yè)大省,在農(nóng)業(yè)強(qiáng)國(guó)建設(shè)中肩負(fù)著重要使命,截至2023年,河南累計(jì)建成高標(biāo)準(zhǔn)農(nóng)田8585萬畝(1畝 =1/15 hm2 ,下同),2022年9月,河南省發(fā)布了《河南省高標(biāo)準(zhǔn)農(nóng)田示范區(qū)建設(shè)實(shí)施方案》,提出到2025年建設(shè)1500萬畝高標(biāo)準(zhǔn)農(nóng)田示范區(qū)的目標(biāo),以持續(xù)提升農(nóng)業(yè)綜合生產(chǎn)能力。持續(xù)推進(jìn)高標(biāo)準(zhǔn)農(nóng)田建設(shè)、提升耕地地力,是鞏固和提高糧食生產(chǎn)能力、保障國(guó)家糧食安全的關(guān)鍵舉措,是實(shí)施鄉(xiāng)村振興戰(zhàn)略的重要支撐。
