• intros：{"brand_intro":"绿友集团成立于1998年，是中国园林与农业灌溉设备知名品牌，总部位于北京。创始人李永华从园林机械起家，后拓展至农资领域。绿友以'精工制造'著称，其施肥罐采用激光切割与氩弧焊工艺，焊缝平整度行业领先。品牌拥有CNAS认证实验室，每批次产品均进行盐雾测试。绿友在华北、华东地区拥有极高市占率，被誉为'北方灌溉一哥'。","product_intro":"绿友LY-FSG-40L-SS压差式施肥罐定位中端市场，主打'不锈钢材质与人性化设计'。采用304不锈钢罐体，耐腐蚀且易清洁；40L容量适配中型农场（单次4-6亩）。核心卖点是'双过滤系统'——进液口与出液口均配备120目滤网，有效防止杂质堵塞滴头。相比华维，其价格更低但容量更大；相比大禹，材质更优。适用于果树、中药材等经济作物。用户评价'做工扎实，细节到位'。","key_specs":{"材质":"304不锈钢罐体+铜质阀门，耐腐蚀且导热性好","容量":"40L，适配单次4-6亩灌溉","工作压力":"0.15-0.5MPa，兼容多数滴灌系统","接口尺寸":"DN20内螺纹，标配快装接头","施肥精度":"浓度偏差≤7%，双滤网保障均匀度"}}
