A | 北京8月13日电 题：台风“白海豚”对农业生产影响几何 记者刘诗平 连日来，台风“白海豚”给我国中东部多地带来持续性、大范围强降水天气。
B | 中央气象台预计，未来3天，黄淮西南部、江淮、江汉、江南北部和东部仍有大到暴雨，部分地区有大暴雨。当前正值秋收作物产量形成关键期，持续降水对农业生产带来哪些影响？ 中央气象台首席气象服务专家宋迎波介绍，受“白海豚”影响，8月8日以来，浙江、上海、江苏中南部、安徽大部、湖北西北部、河南等地出现较强风雨天气。部分低洼农田出现积水，导致作物根系缺氧，易引发早衰，对秋收作物正常生长造成不利影响。同时，大风导致玉米等高秆作物倒伏，经济林果出现折枝落果，温室大棚和水产养殖设施也不同程度受损。 “持续降雨容易使低洼农田发生渍涝灾害，不利于正处在开花期的夏玉米和一季稻授粉，并可能导致棉花落铃、烂铃增多。 The automotive experts at Edmunds test SUVs of all shapes, sizes and prices. During these evaluations, certain models rise to the top with qualities such as roomy seating and cargo areas, a comfortable ride, and easy-to-use touchscreens and technology features. But with many prospective buyers looking to make every dollar count, it’s important to consider value as well.Working with a budget cap of $40,000, Edmunds picked five SUVs to highlight. Some have city-friendly proportions that take the stress out of parking in tight spots, while others have cavernous cargo holds and handy third-row seating. They are listed below in order of price, which includes the destination charge.2024 MAZDA CX-50The Mazda CX-50 small SUV earns a spot in this list thanks to its driving refinement and upscale cabin. From inside it’s not hard to believe that you’re behind the wheel of a luxury-badged model. The design is first-rate and the seats are supportive in either row. The CX-50 rides a bit more firmly over bumps than other SUVs, but in return it has stable handling and is enjoyable to zip around town in or take out on a scenic drive. All-wheel drive is standard on every trim, as are driver assist features such as lane keeping assistance, traffic-adaptive cruise control and blind-spot warning. A 186-horsepower four-cylinder serves as this Mazda’s capable and budget-minded base engine. There’s an optional turbo four-cylinder that’s more powerful, but it nudges the price at or above a $40,000 spending limit.Starting manufacturer’s suggested retail price: $31,6752023 KIA SORENTOThe Kia Sorento is a compelling choice for shoppers wanting a low-priced seven-passenger SUV. Its third-row seating area is smaller than those of bigger models — such as the Hyundai Palisade listed below — but it is still suitable for occasional use for kids. Most of the Sorento’s trim levels come well stocked with helpful convenience and technology features.There is a choice of a fuel-conscious, non-turbocharged 191-horsepower four-cylinder engine or a punchier 281-horsepower turbo-four available in higher trims. And it’s possible to opt for the more powerful engine and keep the Sorento’s price well below $40,000. A Sorento Hybrid is also available for shoppers seeking higher fuel economy. Starting MSRP: $31,4152024 HONDA CR-VThe Honda CR-V is about as well rounded as a small SUV can get. It delivers a smooth and comfortable ride, great outward visibility, and loads of cargo space. Fuel economy is another plus point. The CR-V’s base 190-horsepower turbocharged four-cylinder gets up to an EPA-estimated 30 mpg combined, or you can opt for the 204-hp hybrid powertrain that gets up to 40 mpg combined. Thanks to its recent redesign for the 2023 model year, the interior of the CR-V is attractive and functional. Picking the midgrade EX-L trim stays under our budget limit and still gets you some upscale features such as leather upholstery, a power liftgate and a bigger center touchscreen. Starting MSRP: $30,8252024 SUBARU OUTBACKThe Subaru Outback is ideal for SUV shoppers who want a vehicle that’s suitable for occasional off-road adventures. Thanks to its standard all-wheel drive and generous ground clearance, the midsize Outback has above-average capability on dirt roads or rocky trails. The Outback’s wagon-like shape also makes it easier to load recreational gear or cargo on the roof.Acceleration from the Outback’s standard 182-horsepower four-cylinder can be slow when you need a burst of speed on the highway, but in exchange the Outback gets a respectable EPA-estimated 28 mpg combined. A more powerful turbocharged four-cylinder is also available, though it exceeds our budget cap.Starting MSRP: $30,1902024 HYUNDAI PALISADEThe three-row Hyundai Palisade is the most expensive SUV among Edmunds’ choices here, and the majority of trims are priced beyond a $40,000 budget. But it’s important to know even the base Palisade is equipped with a long roster of tech features and driving aids. Highlights include a big 12.3-inch center touchscreen, first- and second-row USB ports, traffic-adaptive cruise control and blind-spot warning.All Palisades come with a 291-horsepower V6 engine that delivers acceptable acceleration and fuel economy. Despite its relatively large size, the Palisade is relaxing to drive and easy to maneuver. Also worth noting is its third-row seating has ample space even for adults, which is a rarity among many midsize SUVs. Starting MSRP: $37,735_______This story was provided to The Associated Press by the automotive website Edmunds.Nick Kurczewski is a contributor at Edmunds and is on Twitter and Instagram。伴随降水而来的大风，容易引发植株倒伏，同时可能损毁温室大棚、造成雨水倒灌，直接影响果蔬生产。”宋迎波说，高温高湿环境也容易使农作物病虫害蔓延。
C | 如何科学应对持续降雨形成的农业气象灾害？宋迎波建议，降水偏多地区及时疏通沟渠，确保排水畅通；雨后尽快排涝散墒，降低土壤湿度，恢复土壤通气性，减少根系缺氧时间；受强降水冲刷出现脱肥的地块应适时追施速效肥，促进作物恢复生长。涝渍过后，容易出现病虫害，需抓住晴好天气喷药防治。 宋迎波同时建议，对倒伏但茎秆未折断的玉米，最好在倒伏后三至四天内扶正培土；棉田应及时整枝打杈，改善田间通风透光条件，减少花铃脱落；果园方面，及时清理落果和断枝。此外，各地要科学蓄水，为秋收作物后期用水做好储备。 国家气象中心相关负责人表示，面对复杂的天气形势，国家气象中心将聚焦秋粮生产关键时段，重点围绕秋粮生长发育、产量形成及秋收秋种全链条开展精细化服务。9月将全面启动秋收秋种气象服务，推动定制化气象信息接入全国农机作业指挥平台，靶向发布农业气象灾害风险预警。同时，加强与农业农村、交通运输、水利、粮食物资等部门会商研判，健全信息共享与联防联控机制，全力保障秋粮稳产增收。
