湖北：機(jī)械化施肥優(yōu)化方式突出“智”

2023-08-23 09:30:43 來(lái)源：湖北省農(nóng)業(yè)農(nóng)村廳 閱讀量：18813 評(píng)論

導(dǎo)讀：截至目前，湖北省推廣種肥同播、側(cè)深施肥等“三新”技術(shù)面積455.3萬(wàn)畝，引導(dǎo)農(nóng)民科學(xué)施肥，優(yōu)化施肥方式，“智”字少不了。

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】今年以來(lái)，春耕夏收，化肥減量增效不斷推進(jìn)。截至目前，湖北省推廣種肥同播、側(cè)深施肥等“三新”技術(shù)面積455.3萬(wàn)畝，引導(dǎo)農(nóng)民科學(xué)施肥，優(yōu)化施肥方式，“智”字少不了。
 
　　水稻機(jī)械測(cè)深施肥，“智”在長(zhǎng)效
 
　　水稻機(jī)械化測(cè)深施肥通過(guò)水稻插秧與側(cè)深施肥同步技術(shù)手段，一次性將肥料施在秧苗根部側(cè)下方的泥土中。深施選用的緩釋肥，養(yǎng)分釋放緩慢，水稻生長(zhǎng)期可不用追肥。肥料深施在稻根旁，不易流失，方便水稻通過(guò)根系吸收養(yǎng)分，可顯著提高肥料的利用率。同時(shí)避免了大量溶解在水中而隨雨水流入河流，對(duì)河流水質(zhì)帶來(lái)污染少。2023年，荊州區(qū)農(nóng)業(yè)科技服務(wù)中心在川店、馬山、八嶺山等鎮(zhèn)示范帶動(dòng)水稻機(jī)插秧同步側(cè)深施肥技術(shù)2.4萬(wàn)畝，技術(shù)推廣面積連續(xù)三年超過(guò)2萬(wàn)畝，利用水稻側(cè)深施肥技術(shù)后增產(chǎn)6.21-12.43%，畝增產(chǎn)達(dá)44-100公斤，農(nóng)戶(hù)增收效果明顯。
 

 
       油菜無(wú)人機(jī)種肥同播，“智”在快速
 
　　油菜免耕飛播技術(shù)是將肥料與一定量的種子均勻拌和，然后通過(guò)無(wú)人機(jī)空中進(jìn)行撒施播種。依據(jù)油菜播種時(shí)間，在水稻收獲前后用農(nóng)用無(wú)人機(jī)油菜種肥同播，可節(jié)約人工勞動(dòng)成本，播種均勻，充分發(fā)揮谷林環(huán)境，利用土壤墑情，提前出苗，并降低草害。通過(guò)無(wú)人機(jī)增加播幅，提高耕地利用率。荊州區(qū)去年油菜免耕油菜飛播示范5000畝，無(wú)人機(jī)可一次飛施油菜專(zhuān)用肥40千克，畝播種量350克，播種速度可達(dá)5米/秒，每小時(shí)可播種30-50畝，作業(yè)效率明顯提高。
 

 
       機(jī)械化秸稈還田，“智”在減量
 
　　在小麥、水稻、油菜等作物收割季，聯(lián)合收割機(jī)裝配粉碎裝置下田，在收割農(nóng)作物時(shí)對(duì)拋出的秸稈，落地前實(shí)施切碎處理，均勻拋撒還田，解決了大量秸稈還田處理困難的問(wèn)題，有助于秸稈還田工作的順利進(jìn)行。武穴市大力推廣油菜、水稻等大宗作物秸稈還田技術(shù)，常年累計(jì)應(yīng)用面積達(dá)50余萬(wàn)畝，在武穴市大金鎮(zhèn)周干畈田間調(diào)查統(tǒng)計(jì)顯示，秸稈還田對(duì)農(nóng)作物產(chǎn)量、土壤有機(jī)質(zhì)含量、耕作層容重、農(nóng)作物抗逆性等都有明顯影響，秸稈還田比不還田的土壤有機(jī)質(zhì)含量提升2.63g/kg，全氮含量增加0.15g/kg，有效磷增加0.32mg/kg，速效鉀增加27.29mg/kg，緩效鉀增加35.13mg/kg，秸稈還田的田塊較不還田耕作層增厚10cm以上。耕地質(zhì)量明顯提升，化肥施用量明顯減少。
 
　　藏糧于地，藏糧于技。地由肥養(yǎng)，肥由技施，將施肥技術(shù)機(jī)械化、智能化，推進(jìn)化肥減量增效，實(shí)現(xiàn)綠色發(fā)展，讓作物“吃飽喝足”，糧食量多質(zhì)高。
