綠葉蔬菜是大眾喜食的蔬菜之一,但由于其生長(zhǎng)周期短,很容易受到農(nóng)藥的污染,蔬菜防蟲網(wǎng)覆蓋技術(shù)的誕生,為大幅度減少農(nóng)藥使用量和使用次數(shù),生產(chǎn)出無(少)農(nóng)藥污染的綠色蔬菜。但應(yīng)用防蟲網(wǎng)覆蓋栽培技術(shù)時(shí)還應(yīng)注意以下幾點(diǎn)，西雙版納防蟲網(wǎng)哪家便宜。 1)應(yīng)依據(jù)防蟲網(wǎng)的使用季節(jié)合理選用不同透光率的防蟲網(wǎng)品種。春季和秋季選用透光率較好的防蟲網(wǎng),夏季可選用遮陽(yáng)效果較好的防蟲網(wǎng)。 2)應(yīng)根據(jù)作物對(duì)光照的需求特點(diǎn)選用防蟲網(wǎng)品種。需光性較強(qiáng)的,應(yīng)選擇透光率較高的防蟲網(wǎng),反之,可選用具有遮陽(yáng)效果的防蟲網(wǎng)。 3)提倡采用單棟管棚側(cè)邊覆蓋防蟲網(wǎng),頂部用頂膜加遮陽(yáng)網(wǎng)的覆蓋方式。這種覆蓋方式可根據(jù)蔬菜栽培季節(jié)光照的強(qiáng)弱和作物的需光要求,及時(shí)揭蓋遮陽(yáng)網(wǎng),解決防蟲網(wǎng)覆蓋不能因氣候條件變化和蔬菜生長(zhǎng)需求來及時(shí)調(diào)節(jié)透光的矛盾,降低病害及爛菜的發(fā)生。 4)為改善網(wǎng)內(nèi)的通風(fēng)條件,又要確保防蟲網(wǎng)的防蟲效果，西雙版納防蟲網(wǎng)哪家便宜,全網(wǎng)覆蓋的側(cè)邊應(yīng)選用22目防蟲網(wǎng)。 5)蓋網(wǎng)前要進(jìn)行土壤消毒和化學(xué)除草，西雙版納防蟲網(wǎng)哪家便宜,以殺死殘留在土壤中的病原菌和蟲卵、雜草等,控制蟲口基數(shù),阻斷害蟲的傳播途徑。這是防蟲網(wǎng)覆蓋。防蟲網(wǎng)覆蓋栽培是一項(xiàng)增產(chǎn)實(shí)用的環(huán)保型農(nóng)業(yè)新技術(shù).西雙版納防蟲網(wǎng)哪家便宜</p><div

2)茄果類。此類蔬菜在夏、秋季節(jié)易發(fā)生***病，防蟲網(wǎng)阻斷害蟲傳毒途經(jīng)，減少了***病的傳染。同時(shí)隔離了棉鈴蟲、斜紋夜蛾、二十八星瓢蟲、茄黃螟等，減少了爛果。 3)瓜類。主要用于甜瓜、南瓜、西瓜等，有利于減輕***病的發(fā)生和黃守瓜、瓜絹螟等的為害。 4)豆類。防蟲網(wǎng)對(duì)豆莢螟、美洲斑潛蠅的控制效果達(dá)95％以上，還可以增加葉綠素含量，增加葉面積，增強(qiáng)根系活動(dòng)。 5)育苗。每年6-8月是秋季蔬菜育苗的季節(jié)，正值高溫、暴雨、蟲害頻發(fā)期，育苗難度大。使用防蟲網(wǎng)后，蔬菜出苗率高，成活率高，秋苗素質(zhì)好而贏得秋冬蔬菜生產(chǎn)的主動(dòng)權(quán)。 6)蔬菜制種繁種。防蟲網(wǎng)可防止因昆蟲活動(dòng)造成的品種間雜交，從而導(dǎo)致的種子混雜退化?？蓮V應(yīng)用于蔬菜的制種繁種。大理防蟲網(wǎng)哪家好防蟲網(wǎng)需要正確保管壽命才能久.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

防蟲網(wǎng)的應(yīng)用越來越廣，所以為了將防蟲網(wǎng)的作用發(fā)揮得更加完美，和防蟲網(wǎng)相關(guān)的知識(shí)也就一定要了解于心，一、防蟲網(wǎng)規(guī)格防蟲網(wǎng)常用單位是“目”，指的是每平方英寸上的網(wǎng)孔數(shù)目，30目就是有30個(gè)孔。而“φ”是指網(wǎng)孔的直徑為，接近于20目，而“4*4”就是4mm平方的方形孔了。二、防蟲網(wǎng)使用季節(jié)在農(nóng)業(yè)生產(chǎn)中防蟲網(wǎng)除了阻擋害蟲進(jìn)棚，還有其它一些功能，按照菜農(nóng)的話來說，防蟲網(wǎng)并不是夏季**，一年四季都用得上，只不過使用的目的不同。三、防蟲網(wǎng)分類依材質(zhì)：尼龍防蟲網(wǎng)、全新料防蟲網(wǎng)等；依作用對(duì)象：臍橙防蟲網(wǎng)、蔬菜防蟲網(wǎng)等；依使用范圍：溫室大棚防蟲網(wǎng)、農(nóng)業(yè)防蟲網(wǎng)、汽車防蟲網(wǎng)等。 </p><p>在農(nóng)業(yè)生產(chǎn)中，溫室大棚防蟲網(wǎng)除了阻擋害蟲進(jìn)棚，還能夠調(diào)節(jié)氣溫、土溫以及濕度。在選購(gòu)大棚防蟲網(wǎng)的過程中，要注意以下兩點(diǎn)。 1、在大棚防蟲網(wǎng)的選擇上，要考慮紗網(wǎng)的目數(shù)、顏色和幅寬等。如果目數(shù)太少，網(wǎng)眼偏大，則起不到應(yīng)有的防蟲效果；而且目數(shù)若是過多，網(wǎng)眼太小，雖能防蟲，但通風(fēng)不良，導(dǎo)致溫度偏高，遮光過多，則不利于作物生長(zhǎng)。但是對(duì)于棚外雜草較多，粉虱較多的，要根據(jù)粉虱體型的大小，防止其從防蟲網(wǎng)的孔眼中進(jìn)入，建議菜農(nóng)使用較密的防蟲網(wǎng)，如40-60目的。過密的通風(fēng)不好，定植后棚室里夜間降溫困難。但是，目前紗網(wǎng)市場(chǎng)生產(chǎn)出的紗網(wǎng)網(wǎng)孔是長(zhǎng)方形的，40目紗網(wǎng)的網(wǎng)孔窄邊可達(dá)30多目，寬邊往往只有20多目，達(dá)不到阻擋煙粉虱的要求，所以只能使用50～60目的紗網(wǎng)阻擋煙粉虱。春秋季節(jié)溫度較低，光照較弱，宜選用白色防蟲網(wǎng)。夏季為了兼顧遮陽(yáng)、降溫，宜選用黑色或銀灰色防蟲網(wǎng)。在蚜蟲和***病發(fā)生嚴(yán)重的地區(qū)，為了驅(qū)避蚜蟲、預(yù)防***病，宜選用銀灰色防蟲網(wǎng)。 2、選用防蟲網(wǎng)時(shí)，還要注意檢查防蟲網(wǎng)是否完整。有些菜農(nóng)反映不少剛買的防蟲網(wǎng)都存在破孔現(xiàn)象，因此提醒菜農(nóng)，在購(gòu)買時(shí)應(yīng)該將防蟲網(wǎng)展開，檢查防蟲網(wǎng)是否存在破孔現(xiàn)象。防蟲網(wǎng)在使用要注意什么？</p><div

大棚蔬菜想要長(zhǎng)得好，病蟲害防治是一定要有的。河北博眾絲網(wǎng)公司是專業(yè)的溫室大棚防蟲網(wǎng)廠家，下面小編給大家介紹幾點(diǎn)大棚蔬菜病蟲害防治策略。 </p> <p> <br /> </p> <p> 1生態(tài)防治 </p> <p> 因?yàn)榇笈锢锏氖卟艘话闵L(zhǎng)溫度和濕度都較高，還容易出現(xiàn)通風(fēng)不良等問題，尤其是當(dāng)土壤的pH值偏向于酸性的時(shí)候，就容易引發(fā)病蟲害。要有效避免這種情況的出現(xiàn)，需要根據(jù)實(shí)際情況采取有效的生態(tài)防治措施： </p> <p> 一是在晴朗的日子，對(duì)大棚進(jìn)行通風(fēng)工作，保證大棚內(nèi)部的空氣自由流通，可以有效防止病蟲害發(fā)生； </p> <p> 二是要求工作人員對(duì)大棚環(huán)境充分熟悉，盡量利用天然條件防治蟲害，減少人工干預(yù)，這樣，可以保證蔬菜免受人為因素的影響； </p> <p> 三是做好對(duì)大棚蔬菜的嚴(yán)格監(jiān)督控制工作，一旦發(fā)現(xiàn)異常情況，要找到問題源頭，制定有效解決方案，使問題控制在可以解決的范圍之內(nèi)。防蟲網(wǎng)遮光不多,不需日揭夜蓋或晴蓋陰揭.西雙版納防蟲網(wǎng)哪家便宜</p><p style="text-indent:25px">防蟲網(wǎng)的優(yōu)點(diǎn)是廢棄物易處理.西雙版納防蟲網(wǎng)哪家便宜</p><p> <strong>防蟲網(wǎng)的使用：</strong> </p> <p> <br /> </p> <p> 1.大棚覆蓋:將防蟲網(wǎng)直接覆蓋在大棚架上，四周用土或磚壓嚴(yán)壓實(shí)。棚頂壓線要繃緊，以防夏季強(qiáng)風(fēng)掀開。留正門揭蓋，方便出入。平時(shí)進(jìn)出要隨手關(guān)門，以防蝶蛾飛人棚內(nèi)產(chǎn)卵。同時(shí)還要經(jīng)常檢查防蟲網(wǎng)有無撕裂口(特別是使用年限較長(zhǎng)的)，一旦發(fā)現(xiàn)應(yīng)及時(shí)修補(bǔ)，確保網(wǎng)室內(nèi)無害蟲侵入。 </p> <p> 2.小拱棚覆蓋:以竹片或鋼筋彎成拱棚插于大田畦面，將防蟲網(wǎng)覆蓋于拱架上，以后澆水直接澆在網(wǎng)上，一直到采收都不揭網(wǎng)，實(shí)行全封閉覆蓋。 </p> <p> <br /> </p> <p> 根據(jù)**有關(guān)組織統(tǒng)計(jì)，全世界每年有七十五萬人發(fā)生農(nóng)藥中毒，其中近二萬人喪生。而我國(guó)近幾年據(jù)農(nóng)業(yè)部、衛(wèi)生部統(tǒng)計(jì)，每年發(fā)生農(nóng)藥中毒人數(shù)均超過十萬人。所有這些中毒大多是因蔬菜殘留農(nóng)藥引起的食物中毒!這是多么的觸目驚心。從蔬菜農(nóng)藥污染的嚴(yán)重使我們看到了推廣使用防蟲網(wǎng)的緊迫性。
