The Challenge: 80% Crop Waste to Market Breakthrough

困境突围：从 80% 烂在地里到永辉超市定点采购

When Zhan Xingjian switched from construction to agriculture in 2013, he never imagined his 220-acre sweet potato leaves (苕尖) farm in Taihe Town, Hechuan District would face 80% spoilage rates. “In 2020, over 40,000kg of tender shoots rotted unsold,” recalls the founder of Chongqing Yangjian Agricultural Development Co., Ltd.

2013 年，詹兴建在合川太和镇流转 100 亩土地种植苕尖，却遭遇严重滞销。”2020 年超 4 万斤苕尖烂在地里”，这位重庆阳建农业总经理坦言初期困境。

Game-Changing Strategy: Circular Agriculture Model

破局关键：养猪 – 沼气 – 有机肥绿色循环系统

In 2021, Zhan invested ¥3.6M to build:

• 1,000㎡ smart pig farm with 300-head capacity
• Biogas system covering 80% energy needs
• Organic fertilizer production replacing 75% chemicals

Results:
✅ Annual fertilizer costs reduced from ¥65,600 to ¥16,400
✅ Yield increased 40% to 50,000kg/year
✅ Achieved EU-Organic Equivalent Certification

2021 年，詹兴建耗资 360 万元打造种养循环体系：

• 千头规模智能化养猪场
• 沼气系统满足 80% 能源需求
• 有机肥替代 75% 化肥使用
  成效：
  ✅ 肥料成本从 6.56 万降至 1.64 万 / 年
  ✅ 年产量提升 40% 至 5 万公斤
  ✅ 获得欧盟有机等效认证
