導讀：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)村部糖料專家指導組，研究提出甘蔗臺風災(zāi)后恢復生產(chǎn)技術(shù)指導意見。

　　【農(nóng)機網(wǎng) 科技創(chuàng)新】 近日，受超強臺風“摩羯”影響，海南、廣東和廣西南部蔗區(qū)出現(xiàn)強風雨，局地甘蔗受災(zāi)較重。為指導受災(zāi)蔗區(qū)科學開展災(zāi)后恢復生產(chǎn)，最大限度減輕災(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)村部糖料專家指導組，研究提出甘蔗臺風災(zāi)后恢復生產(chǎn)技術(shù)指導意見。

及時排水降漬
 
　　臺風帶來強降雨，低洼蔗地易受雨水浸泡，應(yīng)立即開挖排水溝，及時排除田間積水，減少土壤水分，促進蔗根扎穩(wěn)扎深，避免浸泡時間過長，造成甘蔗根系缺氧爛根死亡。

扶正培土補肥
 
　　及時扶正倒伏甘蔗，可將兩行甘蔗交叉捆扎成“人”字形，踩實泥土壓實蔗根，必要時用木棍輔助支撐。通過高培土促進蔗株穩(wěn)扎根，減輕產(chǎn)量損失。扶正的蔗株恢復生長15天后，可松綁促進蔗株正常生長。結(jié)合扶正培土，增施1次速效肥料，以防脫肥，促進蔗株恢復生長。可增施尿素10公斤和鉀肥5公斤。

防治病蟲鼠害
 
　　甘蔗倒伏、破損傷口多，易發(fā)生病蟲鼠害。要加強田間巡查，甘蔗葉部病害、綿蚜、螟蟲和鼠害等發(fā)生較重的蔗區(qū)，應(yīng)及時組織噴施殺菌、殺蟲和滅鼠藥物，開展統(tǒng)一防治。
