襄陽(yáng)市農(nóng)機(jī)中心開(kāi)展水稻單產(chǎn)提升技術(shù)指導(dǎo)

2024-08-08 09:14:43 來(lái)源：湖北省襄陽(yáng)市農(nóng)機(jī)技術(shù)推廣服務(wù)中心 南漳縣武安鎮(zhèn)農(nóng)業(yè)機(jī)械服務(wù)中心 閱讀量：12103 評(píng)論

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】 目前，湖北省襄陽(yáng)市300余萬(wàn)畝水稻逐步進(jìn)入孕穗期，為了確保水稻穗大粒飽，穩(wěn)高產(chǎn)，科學(xué)精準(zhǔn)追施水稻穗肥至關(guān)重要。8月1日，襄陽(yáng)市農(nóng)機(jī)技術(shù)推廣服務(wù)中心、南漳縣武安鎮(zhèn)農(nóng)業(yè)機(jī)械服務(wù)中心專業(yè)技術(shù)人員一行到南漳縣武安鎮(zhèn)陳家集村水稻單產(chǎn)提升農(nóng)機(jī)裝備與農(nóng)藝技術(shù)集成示范點(diǎn)指導(dǎo)農(nóng)用無(wú)人機(jī)追施水稻穗肥。
 
　　湖北陳家集農(nóng)業(yè)發(fā)展有限公司負(fù)責(zé)人彭友輝介紹：“用無(wú)人機(jī)施肥效率很高，三名工人一天可追施穗肥800余畝。”
 
　　市農(nóng)機(jī)中心提醒指導(dǎo)廣大合作社把握“三個(gè)技術(shù)要點(diǎn)”巧用農(nóng)用無(wú)人機(jī)高效追施水稻穂肥：
 
　　—、精準(zhǔn)把控施肥時(shí)間。在水稻主莖桿拔節(jié)圓桿后，葉色正常變淺變黃，撥開(kāi)主莖的葉片，生長(zhǎng)點(diǎn)呈小水泡狀或現(xiàn)少量的絨毛，即幼穗分化進(jìn)入第二期，此時(shí)開(kāi)始追施穗肥時(shí)間適宜。
 
　　二、以鉀肥為主，合理配方。根據(jù)水稻生長(zhǎng)情況適量追加氮、磷等元素肥料或復(fù)合肥。
 
　　三、安全飛控，規(guī)范操縱無(wú)人機(jī)。提前保養(yǎng)維護(hù)好農(nóng)用無(wú)人機(jī)，設(shè)置規(guī)劃好避障點(diǎn)及工作高度，根據(jù)適時(shí)天氣狀況及風(fēng)力等級(jí)合理配置工作載荷。

上一篇： 臨夏舉辦油菜全程機(jī)械化操作技術(shù)現(xiàn)場(chǎng)示范演示活動(dòng)

下一篇：木子店鎮(zhèn)召開(kāi)2024年水稻病蟲(chóng)害綠色防控及統(tǒng)防統(tǒng)治現(xiàn)場(chǎng)會(huì)
