　　【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】當(dāng)前，我省早稻進(jìn)入抽穗揚(yáng)花期，單季晚稻進(jìn)行田間移栽，部分早播早栽的已進(jìn)入分蘗盛期。秋季茄果類(lèi)、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(shí)期。
 
　　根據(jù)省氣象臺(tái)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(shí)清溝排水，加固設(shè)施。及時(shí)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(shí)可用抽水機(jī)進(jìn)行搶排。若遭遇較強(qiáng)降雨，要加固大棚等設(shè)施，及時(shí)封閉大棚。視降雨情況，及時(shí)轉(zhuǎn)移大棚設(shè)施內(nèi)的食用菌、中藥材、花卉等作物。加強(qiáng)茶園、桑園等巡視維護(hù)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(shí)分級(jí)采摘成熟果實(shí)。對(duì)尚有上市價(jià)值的受災(zāi)中藥材，積極采收，減少損失。對(duì)受災(zāi)嚴(yán)重或絕產(chǎn)田塊，天晴后要及時(shí)補(bǔ)種改種，合理安排下茬作物。
 
　　三是加強(qiáng)田間管理，重點(diǎn)防治病蟲(chóng)害。強(qiáng)降雨過(guò)后要及時(shí)做好水稻查苗補(bǔ)苗，排水露苗。要及時(shí)扶理植株，摘除殘枝病葉，中耕施肥，薄肥勤施，促進(jìn)作物恢復(fù)生長(zhǎng)；強(qiáng)降雨過(guò)后田間濕度增大，有利于各種病蟲(chóng)害發(fā)生流行，要做好病蟲(chóng)監(jiān)測(cè)和防治工作，針對(duì)不同品種、危害程度，選擇安全對(duì)口藥劑搶晴用藥。
