• intros：{"brand_intro":"海状元是青岛海大生物集团旗下核心品牌，依托中国海洋大学科研背景，成立于2000年。集团拥有'海洋生物资源开发'国家重点实验室，是国内海藻肥行业标准制定单位之一。创始人单俊伟教授是中国海藻酸应用领域的权威专家。海状元以'科技兴农，蓝色粮仓'为使命，拥有从海藻养殖到终端肥料的全产业链优势。其'双海藻'（海藻+海藻渣）发酵技术获得国家发明专利。品牌连续十年入选'中国农民最信赖的农资品牌'，在北方大田和经济作物区拥有极高渗透率。","product_intro":"海状元海藻钾（颗粒型）是一款缓释型海藻有机钾肥，定位为底肥或追肥两用型产品，特别适合大田作物（水稻、玉米、小麦）及果树基施。核心卖点是'双效合一'：既含海藻酸（≥12%）改良土壤，又含有机钾（≥8%）缓慢释放，肥效长达90天。颗粒坚硬、机械化撒施不扬尘。相比雷力等液体肥，海状元颗粒肥更经济实惠，且适合大型农场机械化作业。适用场景包括果树秋施基肥、蔬菜移栽前底肥、大田作物返青期追肥。竞品对比中，其性价比突出，但速效性略逊于液体肥。","key_specs":{"海藻酸含量":"≥12%，采用酶解+发酵双工艺","有机钾含量":"≥8%，天然海藻钾+矿物钾复配","有机质含量":"≥45%，富含海藻渣发酵物","颗粒规格":"2-4mm圆颗粒，抗压强度高","适用作物":"大田作物、果树、蔬菜、花卉","规格":"20kg/袋"}}
