去年春耕，杨福财以每亩11元的价格，完成150亩农田打药作业，预计今年能覆盖500亩。“单靠人工打药，每人每天最多打5亩，人工费一天至少150元，无人机半天就能打30亩，怎么算都值。”
At its “Awe Dropping” event in September, Apple introduced the AirPods Pro 3. In addition to improved ANC and sound, the third-gen earbuds include a built-in heart rate sensor that syncs with the iPhone Fitness app, allowing you to track your pulse and calories burned across more than 50 workout types. They’re also more comfortable and secure than their predecessor, thanks to a redesigned, angled fit and five ear tip sizes — including a new XXS option. Additionally, they carry a more robust IP57 rating and support Apple’s new live translation feature, which, in our testing, generally conveys the gist well but still can’t beat a human interpreter.
