導(dǎo)讀：為防范和減輕災(zāi)害影響，農(nóng)業(yè)農(nóng)村部種植業(yè)管理司會同全國農(nóng)業(yè)技術(shù)推廣服務(wù)中心、農(nóng)業(yè)農(nóng)村部蔬菜專家指導(dǎo)組，提出蔬菜應(yīng)對臺風(fēng)暴雨生產(chǎn)技術(shù)指導(dǎo)意見。

　　【農(nóng)機網(wǎng) 熱點關(guān)注】 根據(jù)氣象部門預(yù)報，今年第3號臺風(fēng)“格美”將于7月25日在福建中部到浙江南部一帶沿海登陸，最強可達強臺風(fēng)級或超強臺風(fēng)級。臺風(fēng)影響區(qū)域會出現(xiàn)強風(fēng)暴雨，給蔬菜生產(chǎn)帶來不利影響。為防范和減輕災(zāi)害影響，農(nóng)業(yè)農(nóng)村部種植業(yè)管理司會同全國農(nóng)業(yè)技術(shù)推廣服務(wù)中心、農(nóng)業(yè)農(nóng)村部蔬菜專家指導(dǎo)組，提出蔬菜應(yīng)對臺風(fēng)暴雨生產(chǎn)技術(shù)指導(dǎo)意見。
 
　　提前落實預(yù)防措施
 
　　一是加固設(shè)施。蔬菜基地應(yīng)在臺風(fēng)來襲方向設(shè)置風(fēng)障等臨時性保護措施，防止或減輕臺風(fēng)危害。以老舊設(shè)施為重點，抓緊檢修加固大棚、溫室，提高設(shè)施抗風(fēng)雨能力。對于已拉秧或空閑設(shè)施，在臺風(fēng)來襲之前，撤掉棚膜，保護設(shè)施骨架結(jié)構(gòu)不被強風(fēng)損壞。
 
　　二是固定植株。培土以防倒伏，并適當控水，促根下扎，防止徒長。加固瓜類、豆類等搭架栽培的高桿蔬菜，用簡易覆蓋物覆蓋矮生植株，防止受風(fēng)搖動。
 
　　三是疏通溝渠。臺風(fēng)來臨前做好田間溝渠清理，確保排水順暢，尤其地勢較低的菜田要在四周搶挖圍溝、腰溝，提升排水能力。
 
　　及時開展減災(zāi)救災(zāi)
 
　　一是排澇降漬。受災(zāi)地塊要爭分奪秒清理田間溝系，加快排除積水。積水嚴重的地塊，盡快抽排積水，降低田間水位，防止長時間積水和雨水倒灌造成蔬菜植株爛根。
 
　　二是查損檢修。及時查看作物倒伏和設(shè)施損壞情況。對倒伏蔬菜要及時扶正、理順和綁定瓜果藤蔓，避免損傷根系，并適時培土壅根，促進新根快發(fā)。受損設(shè)施要及時整修加固，避免次生災(zāi)害。排查檢修棚膜、避雨、遮陽及防蟲等設(shè)施設(shè)備，修復(fù)破損薄膜，卡緊棚膜，拉緊壓膜線，確保安全。
 
　　三是搶收補肥。尚有上市價值的受災(zāi)蔬菜，要及時采收、抓緊上市，減少災(zāi)害損失。受害不嚴重的蔬菜，可通過噴施葉面肥，緩解根系受淹導(dǎo)致的生長障礙，促進恢復(fù)生產(chǎn)。
 
　　四是補種改種。強化蔬菜集約化育苗場生產(chǎn)調(diào)度和地區(qū)間調(diào)劑，保障受災(zāi)地區(qū)種苗供應(yīng)。對一些受災(zāi)嚴重甚至絕收的菜地，根據(jù)不同情況及時補種改種小白菜、蕹菜、生菜、甘藍、青花菜、蘿卜等速生蔬菜?；謴?fù)生產(chǎn)的設(shè)施，盡快安排種植秋延后茄果類、瓜類蔬菜。
 
　　五是防控病蟲。臺風(fēng)過境后，及時清理田間病株、病枝、病葉，通過控制田間濕度、噴施廣譜性殺菌劑等預(yù)防病害發(fā)生，必要時合理應(yīng)用高效低殘留農(nóng)藥進行病害防治。用藥時要注意交替用藥，遵守農(nóng)藥使用安全間隔期。
