一 | Investigators said Friday they found hydraulic fluid leaking from a hose in the landing gear system of a FedEx plane that was forced to make an emergency landing this month in Chattanooga, Tennessee.The National Transportation Safety Board said that investigators also found a “discontinuity” in the wiring of an alternate system for lowering the landing gear.Video captured by emergency responders showed sparks flying after the Boeing 757 touched down on Oct. 4 with the left landing gear not fully extended. The plane ran off the end of the runway, but none of the three crew members were injured.The pilots reported that after taking off from Chattanooga, they got a warning about low fluid level and a lack of pressure in one of the hydraulic systems, and they decided to return to the airport. After getting an alert about the landing gear, the pilots declared an emergency. They did a low fly-by that allowed people in the airport tower to confirm that the left landing gear was not extended. The pilots circled and landed with the crippled gear. They were able to keep the plane going straight but couldn't stop until 830 feet beyond the end of the runway, the NTSB said in a preliminary report. Pilots used a slide to get out of the plane.The NTSB said an examination showed that a hose tied to a component used to activate the landing gear was leaking hydraulic fluid.The NTSB said it is continuing to investigate the incident.。 中国小康网讯 记者张玉荣 实习记者郑佩瑜 4月19日上午,三亚市“8590”青年干部读书班(第二期)组织50名学员来到育才生态区榴莲种植基地参观调研。活动现场 一下车,大家三五成群地围住育才生态区榴莲种植基地工作人员频频发问。在基地小广场上,瞬间形成了几个小方队,一问一答,热闹非凡。山间小路上,曾经到访过的学员同其他学员分享着考察经验。不一会,大家来到基地水肥一体化智能灌溉系统管理设备点。

二 | “榴莲树喜湿怕涝。能否成活关键在于精准灌溉。”基地工作人员介绍说,他们对多个榴莲品种适应区域的光照、温度、湿度等气候因素开展了数字化比对研究,找出各自的优劣势,以便更好地破解三亚榴莲种植的短板。“基地安装了28套土壤墒情监测仪,根据数据反馈情况,按照榴莲树生长环境设定用水量并通过智能灌溉机实现精准灌溉。” 基地工作人员一边介绍,一边带领大家来到一处仪器站。“目前,基地安装了虫情测报仪、环境检测气象站等,采集基地环境数据,再通过数据指挥中心实现数字化、智能化种植。”“利用现代光、电、数控等技术,实现害虫诱捕、虫体远红外自动处理,并实时将虫害情况上传云平台对害虫种类、数量、趋势进行分析,若分析结果异常会实时报警通知,实现虫情变化的监测及预防。”在1台虫情测报仪前,几名学员仔细研究,探讨基地数字化、智能化防治虫情的新技术。 太阳能振频杀虫灯、环境监测气象站、土壤墒情监测站、太阳能虫情测报仪、智能灌溉主机及水位监测、孢子捕捉仪……榴莲种植各种“保植”大数据,不断在学员们眼前呈现。 在参观调研中,学员们对“新质生产力赋能热带特色高效农业发展”的概念逐渐明晰。“每一株茂盛的榴莲树,每一个饱满的果实,都似乎在诉说着现代农业与科技的融合故事。”读书班学员陈奇益表示,新质生产力如何改变和重塑热带特色高效农业,三亚榴莲是一个典范实践。 “育才生态区榴莲基地为我们打开了一个全新的视野。

三 | 无论是精准施肥、智能灌溉,还是病虫害防治,都体现出一种前所未有的精准和高效。

四 | 与此同时,智能化管理手段的应用,也使得榴莲的生长过程得到了全程监控和调度,确保了产量和品质的双重提升。

五 | ”陈奇益表示,新质生产力的注入将推动农业向数字化、智能化、绿色化方向发展,形成独特的农业王牌力量。三亚的热带特色高效农业也必将迎来更加广阔的发展空间和无限可能。编辑:麦婉华。
