玉米吃上“营养餐” “一喷多促”助增产_我的网站

一 |     A powerful Monday morning earthquake has killed at least 111 and injured 87 in the west part of Colombia.         Colombia's President Abelardo de la Espriella, who came to office just three days before the earthquake, declared a state of emergency to expedite funding for the quake recovery with a plan to visit the disaster zone.    "I am at the forefront of the situation. It pains me deeply what the families and affected regions are going through," he posted on X.    According to information provided by Colombian officials by mid-afternoon, the destruction included 1,575 damaged homes, 37 homes completely destroyed, 61 collapsed buildings, scores of damaged centers of health, education and community, as well as 18 damaged roads and six airports.    Airports in Pereira, Manizales, Quibdo, Armenia, Cartago and Buenaventura suffered structural damage, and their flight operations were suspended, according to Colombia's Civil Aviation Authority.    The tremor was felt in Colombia's capital Bogota, which is about 400 kilometers from the epicenter, setting off alarms that prompted people to evacuate many buildings as a precaution.    "At this time there are no reports of injuries or structural damage, only some cracks in buildings," Bogota Mayor Carlos Galan posted on X.    The earthquake damaged the region's major cities including Pereira, Quibdo, Manizales and Cali.    Nubia Carolina Cordoba-Curi, governor of the Choco region, posted on X on Monday morning that "in the capital Quibdo there are injuries and severe damage to buildings".    She posted an update at 2 pm that 12 people were confirmed dead and 84 injured in Choco.    Other local authorities reported at least 40 deaths in the Risaralda region and 27 deaths in the Valle del Cauca region.    Rescue efforts to save people buried under the debris is ongoing.    According to the Colombia Geological Service, the earthquake epicenter was in San Jose del Palmar, Choco. It had a magnitude of 7.4 and a depth of approximately 103 km, making it the strongest earthquake recorded in Colombia in the last decade.    The earthquake was felt by neighboring countries Venezuela, Ecuador and Panama. It was followed by several aftershocks with magnitudes between 2.8 and 4.8, according to the agency.    The agency said that it's common for this region to experience earthquakes of considerable magnitudes due to activities associated with the subduction of the Nazca Plate beneath the South American Plate.    Near the end of June, Venezuela was struck by two earthquakes — with magnitudes of 7.2 and 7.5 — that were only 39 seconds apart. More than 6,000 people were killed, and tens of thousands of people remain missing under the debris.                    。    8月16日，在邢台市南和区大郝村的玉米地里，一株株玉米挺拔整齐，种粮大户韩坤杰使用植保无人机对玉米进行“一喷多促”作业。“一架无人机一天能喷五六百亩地，我这2000亩地，两架无人机两三天就能喷完，省时省工省力。”韩坤杰说，以往人工喷施农药、叶面肥，存在喷洒不均匀、作业效率低等难题。现在植保无人机搭载精准雾化喷洒系统，将杀虫杀菌剂、叶面营养调节剂均匀喷施在玉米植株上，一次性完成防病虫、防早衰、促灌浆多重作业，让玉米吃上了一顿“营养餐”。眼下，南和区的玉米进入了灌浆期，这是产量形成的重要时期，也是病虫害集中发生期。“一喷多促”是玉米稳产增产的关键技术，通过一次喷施实现防病虫、促灌浆、增粒重、提单产的多重效果。为防治病虫害、促进秋粮生长，当地农技人员深入田间地头，为农户传授玉米病虫害防治方法，讲解水肥一体化灌溉技术要点。“我们开展‘一喷多促’技术推广，确保玉米稳产增产措施有效落地，全力以赴夺取秋粮丰收。

二 | ”邢台市南和区农业农村局农技推广研究员温春爽说，作为粮食生产的关键技术，“一喷多促”将病虫统防、增重促灌、抗逆防衰、壮秆抗倒等多重功效集于一次喷施。同时配合施用磷酸二氢钾与氨基酸叶面肥，可延长叶片光合功能期，促进作物生长，提升单产水平。秋粮产量占我省全年粮食总产量的六成以上，病虫害防治是实现粮食稳产增产的关键。我省持续推进“虫口夺粮”行动，开展秋粮病虫防治，加密病虫监测网点，常态化开展田间拉网式普查，及时发布病虫预警信息。紧盯玉米螟、南方锈病等病虫害防控关键窗口期，各地大力发展统防统治、绿色防控，严防重大病虫害区域性暴发流行。作为传统农业大县，武邑县今年整合12家规模化飞防组织，投入专业植保无人机120余架，并依据乡镇耕地规模与服务半径，搭建起“县级统筹+村级对接+组织作业”的一体化植保网络，全面推进“一喷多促”统防统治作业。田管跟得上，丰收有底气。我省以“提单产、保丰收”为目标，把夏播玉米作为主攻方向，组织专家制定夏玉米肥水管理、病虫害防控技术方案。聚焦34个玉米、2个大豆整建制推进县和邯郸市整建制推进市、14个玉米单产提升工程县，打造一批千亩方、万亩片，树立高产典型。同时，省组织省级产业体系专家、农技人员进村入户，开展蹲点包片指导，重点落实科学肥水调控、病虫害防治等措施，持续挖掘单产潜力。用好中央资金和省级玉米“一喷多促”专项经费，落实“一县一策”，推动高产技术直达田间地头。（日报记者 郝东伟）。
