Abstract
Relying on chemical fertilizers, pesticides and other technical means, agricultural output has been increased, but followed by many externality problems, such as food security, health risk, environmental pollution and disruption of ecological balance. The new rice-turtle comprehensive symbolic agricultural system in Deqing, Zhejiang province has achieved good effect. On the one hand, the farmers have realized a win-win situation on the high output of fish and rice without using chemical fertilizers and pesticides, obtaining good economic benefits. On the other hand, the externality problems of food security, non-point pollution has been cured without interfering the natural rules. The balance of farmland ecosystem has also been recovered. The promotion of the rice-turtle symbolic agricultural system model, or the wisdom and basic ideas of this model, will expand positive externality, promoting agricultural sustainable development. The exploring of rice-turtle comprehensive symbiotic agriculture prided us the road to modern agricultural development, combined with local tradition and modern technology, which was efficient, safe and towards the harmony of human and nature.

Key words: comprehensive agriculture; rice-turtle symbolic agriculture; non-point pollution; food security; grain security

不治而治复合共生农业的探索及其效果

摘要:依赖于化肥、农药等技术手段的农业,虽然产量增加却造成了食品安全、健康风险、环境污染及生态系统失衡等一系列外部性问题。浙江德清探索的稻鳖共生新型复合农业生产模式,在不使用农药、化肥的情况下,实现了“百斤鱼、千斤粮、万元产值”的目标,在生产商获得良好经济效益的同时,也实现了稳定粮食产量、确保食品安全和消除面源污染、维持农田生态系统平衡等目标,对外部性顽疾具有“不治而治”的效果。稻鳖共生模式的推广或其基本理念的扩散,可以扩大其正外部性效应,促进农业可持续发展。此类探索回应了地域传统如何与现代技术结合,探索出切合当地实际的高效、安全、人与自然和谐的现代农业发展之路。
