保護(hù)黑土地,國家再出臺重磅文件,這幾種農(nóng)機(jī)迎來利好!

導(dǎo)讀:我國一直實(shí)施嚴(yán)格的耕地保護(hù)制度,做到“像保護(hù)大熊貓一樣保護(hù)耕地”,而黑土地就是“耕地中的大熊貓”。

  【農(nóng)機(jī)網(wǎng) 政策導(dǎo)讀】 眾所周知,黑土地是地球上珍貴的土壤資源,是一種性狀好、肥力高、適宜農(nóng)耕的優(yōu)質(zhì)土地。自然黑土是千萬年前在砂礫和黏土層上發(fā)育的土壤,在雨熱同季的氣候下,形成了茂密的植被層,經(jīng)過幾千年的時(shí)間演變,才變成了深厚肥沃的黑土層。北半球擁有三塊著名的黑土地:一塊在美洲——美國的密西西比河流域;一塊在歐洲——烏克蘭的第聶伯河流域;一塊在亞洲——中國的東北平原。
 
  基于肥沃的黑土地,東北產(chǎn)糧區(qū)的年糧食產(chǎn)量占全國1/4,商品量占全國的1/4,調(diào)出量占全國的1/3,是不折不扣的“壓艙石”、“穩(wěn)壓器”。然而,這一珍貴的土壤資源卻正在面臨著退化甚至消失的風(fēng)險(xiǎn)。自20世紀(jì)開墾以來,東北地區(qū)的黑土層平均厚度由50厘米至60厘米下降到30厘米左右,土壤耕層的有機(jī)質(zhì)含量下降了50%至60%,年均下降速率約為5‰。
 
  我國一直實(shí)施嚴(yán)格的耕地保護(hù)制度,做到“像保護(hù)大熊貓一樣保護(hù)耕地”,而黑土地就是“耕地中的大熊貓”。
 
  雖然近些年來一系列保護(hù)、治理措施初見成效,但是黑土耕地退化趨勢尚未得到有效遏制。已經(jīng)實(shí)施綜合性治理措施的黑土耕地面積占比較低,坡耕地水土流失仍較重,耕作層變薄和侵蝕溝問題仍然突出,土壤有機(jī)質(zhì)含量下降趨勢仍未扭轉(zhuǎn),局部酸化、鹽漬化問題仍然存在。要長久保護(hù)黑土地,還需要多措并舉,持續(xù)推進(jìn),久久為功。
 
  多年來,國家出臺多項(xiàng)制度保護(hù)黑土地。2017 年,原農(nóng)業(yè)部、發(fā)展改革委等 6 部門印發(fā)了《東北黑土地保護(hù)規(guī)劃綱要(2017—2030 年)》,明確到2030 年在東北典型黑土區(qū)實(shí)施 2.5 億畝黑土耕地保護(hù)任務(wù)。2020 年,農(nóng)業(yè)農(nóng)村部和財(cái)政部印發(fā)《東北黑土地保護(hù)性耕作行動計(jì)劃(2020—2025 年)》,明確到 2025年在東北地區(qū)適宜區(qū)域?qū)嵤┮悦飧俑斩捀采w還田為主要內(nèi)容的保護(hù)性耕作 1.4 億畝。
 
  在此基礎(chǔ)上,今年6月,農(nóng)業(yè)農(nóng)村部、國家發(fā)展和改革委員會、財(cái)政部、水利部、科學(xué)技術(shù)部、中國科學(xué)院、國家林業(yè)和草原局等7部門又印發(fā)了《國家黑土地保護(hù)工程實(shí)施方案 (2021—2025年)》(以下簡稱《方案》),針對黑土耕地出現(xiàn)的“薄、瘦、硬”問題,著重實(shí)施土壤侵蝕治理,農(nóng)田基礎(chǔ)設(shè)施建設(shè),肥沃耕作層培育等措施。
 
  《方案》明確,2021—2025 年,實(shí)施黑土耕地保護(hù)利用面積 1 億畝(含標(biāo)準(zhǔn)化示范面積 1800 萬畝)。其中,建設(shè)高標(biāo)準(zhǔn)農(nóng)田 5000 萬畝、治理侵蝕溝 7000 條,實(shí)施免耕少耕秸稈覆蓋還田、秸稈綜合利用碎混翻壓還田等保護(hù)性耕作5 億畝次(1 億畝耕地每年全覆蓋重疊 1 次)、有機(jī)肥深翻還田 1 億畝。到“十四五”末,黑土地保護(hù)區(qū)耕地質(zhì)量明顯提升,旱地耕作層達(dá)到 30 厘米、水田耕作層達(dá)到 20—25 厘米,土壤有機(jī)質(zhì)含量平均提高 10%以上,有效遏制黑土耕地“變薄、變瘦、變硬”退化趨勢,防治水土流失,基本構(gòu)建形成持續(xù)推進(jìn)黑土地保護(hù)利用的長效機(jī)制。
 
  《方案》指出,實(shí)施保護(hù)性耕作。優(yōu)化耕作制度,推廣應(yīng)用少耕免耕秸稈覆蓋還田、秸稈碎混翻壓還田等不同方式的保護(hù)性耕作。在適宜地區(qū)重點(diǎn)推廣免耕和少耕秸稈覆蓋還田技術(shù)類型的“梨樹模式”,增加秸稈覆蓋還田比例。其余地區(qū),改春整地為秋整地,旱地采取在秋季收獲后實(shí)施秸稈機(jī)械粉碎翻壓或碎混還田。
 

 

  實(shí)施有機(jī)肥還田。秋季根據(jù)當(dāng)?shù)赝寥阑A(chǔ)條件和降雨量特點(diǎn),推行深松(深耕)整地,以漸進(jìn)打破犁底層為原則,疏松深層土壤。利用大中型動力機(jī)械,結(jié)合秸稈粉碎還田、有機(jī)肥拋撒,開展深翻整地。在糞肥豐富的地區(qū)建設(shè)糞污貯存發(fā)酵堆漚設(shè)施,以畜禽糞便為主要原料堆漚有機(jī)肥并施用。
 
  結(jié)語:可以看出,免耕播種、深松整地、秸稈粉碎還田、有機(jī)肥拋撒、畜禽糞污處理處理等相關(guān)農(nóng)機(jī)裝備是黑土地保護(hù)中的主要機(jī)械,這幾類農(nóng)機(jī)將迎來重要發(fā)展機(jī)遇。
