導(dǎo)讀：19日至21日，我省中北部有大雨暴雨局部大暴雨。省農(nóng)技推廣中心提醒廣大農(nóng)民，要做好以下技術(shù)管理措施。

　　【農(nóng)機網(wǎng) 熱點關(guān)注】當(dāng)前，我省早稻進入抽穗揚花期，單季晚稻進行田間移栽，部分早播早栽的已進入分蘗盛期。秋季茄果類、草莓等處于播種育苗期，山地蔬菜處于采收上市期，楊梅、桃等水果處于成熟采收期，鮮食玉米、鮮食大豆處于成熟上市期，食用菌、中藥材、花卉等也處于生產(chǎn)重要時期。
 
　　根據(jù)省氣象臺信息，昨天麗水、溫州南部、衢州南部等地出現(xiàn)大雨暴雨，局部大暴雨。19日至21日，我省中北部有大雨暴雨局部大暴雨。省農(nóng)技推廣中心提醒廣大農(nóng)民，要做好以下技術(shù)管理措施。
 
　　一是及時清溝排水，加固設(shè)施。及時清理排水溝，疏通排水渠道，排除田間積水，防止?jié)n害發(fā)生。必要時可用抽水機進行搶排。若遭遇較強降雨，要加固大棚等設(shè)施，及時封閉大棚。視降雨情況，及時轉(zhuǎn)移大棚設(shè)施內(nèi)的食用菌、中藥材、花卉等作物。加強茶園、桑園等巡視維護工作。
 
　　二是及早搶收成熟作物，合理安排下茬作物。搶收成熟或近成熟的瓜菜、易受淹田地和不耐澇品種蔬菜。抓住晴好天氣，及時分級采摘成熟果實。對尚有上市價值的受災(zāi)中藥材，積極采收，減少損失。對受災(zāi)嚴重或絕產(chǎn)田塊，天晴后要及時補種改種，合理安排下茬作物。
 
　　三是加強田間管理，重點防治病蟲害。強降雨過后要及時做好水稻查苗補苗，排水露苗。要及時扶理植株，摘除殘枝病葉，中耕施肥，薄肥勤施，促進作物恢復(fù)生長；強降雨過后田間濕度增大，有利于各種病蟲害發(fā)生流行，要做好病蟲監(jiān)測和防治工作，針對不同品種、危害程度，選擇安全對口藥劑搶晴用藥。
