眼镜市场防蓝光近视防控镜片需求增

财源广进

眼镜市场防蓝光近视防控镜片需求增【7xP8mbQ9vR】5月21日，“国际茶日”，一个属于小小茶叶的节日。

茶之源，始于华夏；茶之路，连通四海。茶是世界三大饮品之一，全球产茶国和地区达60多个，饮茶人口超过20亿。从古代丝绸之路、茶马古道、茶船古道，到今天丝绸之路经济带、21世纪海上丝绸之路，茶穿越历史、跨越国界，深受世界各国人民喜爱。

一片叶子带富一方百姓，科技加持下，茶香绵延中，茶文化、茶产业绘就一幅传承中创新发展的美丽画卷。

我国是茶叶生产和消费大国。中国茶叶流通协会数据显示，我国拥有超5000万亩茶园，去年茶叶产量超360万吨，总产值超3000亿元。

从“看天吃饭”到“看屏种茶”，茶园有了越来越多科技元素。

走进广西横州市的茉莉花种植区，“数字茉莉”种植大棚里几乎看不到花农的身影。取而代之的是24小时运转的物联网传感器和智能摄像头。它们实时捕捉土壤温湿度、光照、养分等数据，自动调控水肥灌溉系统。

“以前种花全凭经验，现在看手机就行。”横州市花农老黄说，自从接入“数字茉莉”平台，他家的花田实现了按需供水供肥，花期延长了一个多月，节水节肥超30%，每亩多挣3600元。

随着物联网、5G、无人机等技术的广泛应用，越来越多茶园装上了“数字大脑”。
