導(dǎo)讀： 俗話說“一年之計(jì)在于春”，柑橘春季植保是柑橘整年的命根子。關(guān)鍵時(shí)期不抓好，就會(huì)發(fā)育不良，后期病蟲害增多，后導(dǎo)致產(chǎn)量跳水。

　　【農(nóng)機(jī)網(wǎng) 明星企業(yè)】 俗話說“一年之計(jì)在于春”，柑橘春季植保是柑橘整年的命根子。關(guān)鍵時(shí)期不抓好，就會(huì)發(fā)育不良，后期病蟲害增多，后導(dǎo)致產(chǎn)量跳水。

　　那么如何進(jìn)行春季柑橘植保，主要分為三步：第一、春季柑橘園面臨紅蜘蛛、蚜蟲、木虱等蟲害以及瘡痂病、沙皮病等病害，需要進(jìn)行病蟲害防治。第二、春季柑橘開始開花結(jié)果，需要使用一些葉面肥促花促果。第三、對(duì)于春梢生長(zhǎng)旺盛的品種，還應(yīng)當(dāng)使用一些化學(xué)藥劑抑制春梢生長(zhǎng)，防止柑橘徒長(zhǎng)。

　　隨著果樹飛防的普及，今年春天的柑橘園中隨處可見大疆植保機(jī)的身影。下面就來看一下大疆植保機(jī)是怎樣在柑橘春季植保中發(fā)揮作用的吧！
 
　　福建福鼎：千畝柚子黃龍病防治
 
　　四季柚是福建省福鼎市前岐鎮(zhèn)的支柱產(chǎn)業(yè)，全鎮(zhèn)種植面積約 10050 畝，年總產(chǎn)值 9000 多萬元。然而當(dāng)?shù)厮募捐终艿近S龍病的威脅。柑橘黃龍病是由細(xì)菌引起的毀滅性病害，柑橘得病后無藥可治，因此被稱為“柑橘的癌癥”。柑橘黃龍病主要有柑橘木虱傳播，因此有效控制柑橘木虱數(shù)量即可抑制黃龍病爆發(fā)。

四季柚
 
　　2020 年 3 月中旬，應(yīng)當(dāng)?shù)卣?qǐng)，福建鼎飛科技有限公司植保隊(duì)出動(dòng)兩架 1P ，兩架 T16 對(duì)前岐鎮(zhèn) 1400 畝柚子進(jìn)行木虱的防治，用4天時(shí)間完成了防治任務(wù)。

　　作業(yè)參數(shù)

　　參數(shù)解讀：作業(yè)總面積大，地塊分散，需要快速機(jī)動(dòng)的作業(yè)方式。因此采用手動(dòng)作業(yè)模式，節(jié)省了規(guī)劃地塊的時(shí)間。前岐鎮(zhèn)的四季柚采用矮化種植方式，冠層較薄，葉片較少，對(duì)藥液穿透性的要求較低，采用4米的飛行速度可提高作業(yè)效率。4升的畝用量保證了藥液的覆蓋度。
 
用藥信息

柑橘木虱
 
　　此次用藥的目的是防治木虱。聯(lián)苯菊酯是高效廣譜的殺蟲劑，具有觸殺和胃毒作用，可防治各種鱗翅目和同翅目害蟲。螺蟲乙酯具有很強(qiáng)的內(nèi)吸傳導(dǎo)性，可防治刺吸式口器害蟲。兩種藥劑的復(fù)配對(duì)木虱的殺蟲活性高，并且能維持很長(zhǎng)的持效期。
 
　　廣西融安：砂糖橘蚜蟲防治
 
　　2020 年 3 月下旬，春意正濃。廣西融安縣大良鎮(zhèn)的柑橘到了發(fā)春梢、開花的季節(jié)。然而幼嫩的春梢正在遭受蚜蟲的危害，由于連日的陰雨，加上氣溫偏高，柑橘發(fā)生病害的風(fēng)險(xiǎn)大。3 月 21 日，多日的降雨終于停止，當(dāng)?shù)啬彻麍@趕緊抓緊時(shí)間，對(duì) 100 多畝果樹進(jìn)行了病蟲害防治。

砂糖橘
 
　　作業(yè)參數(shù)

　　參數(shù)解讀：果園處在丘陵地帶，地勢(shì)不平，因此先用 P4R 對(duì)地塊進(jìn)行測(cè)繪，用大疆智圖進(jìn)行建圖并生成航線。將飛行速度降低到2米可提高藥液的穿透性。畝用藥量用 4.5 升可保證藥液的覆蓋度。
 
　　用藥信息

　　此次用藥的目的是防治蚜蟲并預(yù)防病害。高效氯氰菊酯是一種高效廣譜的擬除蟲菊酯類殺蟲劑，具有觸殺和胃毒作用，可防治鱗翅目和半翅目的害蟲。
 
　　吡蟲啉具有內(nèi)吸活性，主要用于防治刺吸式口器害蟲，可有效防治蚜蟲。苯醚甲環(huán)唑和吡唑醚菌酯均為內(nèi)吸性殺菌，具保護(hù)和治療作用。兩者在真菌中的作用位點(diǎn)不同，因此兩者復(fù)配可提升病害的防治效果。

　　江西贛州：臍橙保花保果
 
　　2020 年 3 月 11 日，江西省贛州市崇義縣四季橙園家庭農(nóng)場(chǎng)在拿到新買的 T20 之后，迫不及待地在自己的果園中進(jìn)行試用。四季橙園面積達(dá) 500 畝，種植了各種品種的橙子。不同品種的橙子在不同時(shí)間成熟，因此園中一年四季都能收獲橙子。此次作業(yè)植保機(jī)教員的指導(dǎo)下，對(duì) 30 畝的夏橙和紐荷爾臍橙進(jìn)行殺蟲和?；ū９鳂I(yè)。

用戶喜提 T20 新機(jī)
 
　　作業(yè)參數(shù)

　　參數(shù)解讀：果園由耕地改造而來，地形較為平坦。因此選擇用遙控器上的 RTK 模塊對(duì)地塊直接進(jìn)行航線規(guī)劃，可達(dá)到厘米級(jí)的規(guī)劃精度。為保證作業(yè)效果，將飛行速度降低到 2.5 米，畝用藥量提高到 5 升，以提高藥液的穿透性和覆蓋度。
 

用藥信息
 

　　此次用藥的目的是防治田中零星發(fā)生的蟲害并促進(jìn)開花和果實(shí)膨大。高效氯氰菊酯是一種廣譜的擬除蟲菊酯類殺蟲劑，可防治鱗翅目和半翅目的害蟲。啶蟲脒具有內(nèi)吸活性，主要用于防治刺吸式口器害蟲，在柑橘中主要用于防治蚜蟲和薊馬。
 

　　螺蟲乙酯具有很強(qiáng)的內(nèi)吸傳導(dǎo)性，在柑橘中可防治蚜蟲、薊馬、蚧殼蟲和紅蜘蛛等，是一款很適合柑橘飛防的藥劑。打硼肥有利于促進(jìn)開花和果實(shí)膨大。添加飛防助劑有利于促進(jìn)藥液在果樹葉片上的擴(kuò)散以及果樹對(duì)藥液的吸收。

　　大疆植保無人機(jī)的出現(xiàn)翻開了果樹植保的新篇章。靈活多變的作業(yè)模式，強(qiáng)大的風(fēng)場(chǎng)和超大的流量保障了作業(yè)效果，使大疆植保機(jī)成為果樹飛防的得力助手。即將發(fā)布的果樹模式 3.0賦予了大疆植保機(jī)更強(qiáng)大的果樹作業(yè)能力，讓我們共同期待。
