水稻、小龙虾连作和共作模式,是指在水稻田里通过田间工程改造,合理套养一定数量的小龙虾,发挥小龙虾除草和排泄物增肥等功效,实现水稻、小龙虾共生,以取得生态环保、高产高效的目的。这种模式可实现“田面种稻,水体养虾,虾粪肥田,稻虾共生”的效果,是一种把种植业和水产养殖业有机结合的立体生态农业生产方式,符合资源节约、环境友好和循环高效的农业经济发展要求。该模 Continuous farming and co-production of rice and crayfish refers to the effect of paddy lobster shrimp weeding and excrement fertilizing to realize the symbiosis of rice and crayfish through field engineering reformation in the paddy field and properly raising a certain amount of crayfish To obtain the purpose of ecological protection, high yield and high efficiency. This model can achieve the effect of “field planting rice, water shrimp, shrimp manure, rice shrimp symbiosis”, which is a three-dimensional eco-agricultural production mode that integrates planting and aquaculture organically and is in line with resource conservation, Environmental Friendly and Recycling-efficient Agricultural Economic Development Requirements.
