A method of circular cultivation of lobster in paddy field is introduced, which includes excavation of circular lobster pond, leveling of middle planting area, excavation of circular lobster pond with width of not less than 2 meters and depth of not less than 1 meter along the edge of paddy field. In the middle of the circular lobster pond, there is a flat planting area; crop planting, fake seedling of water chestnut in early and middle April, transplanting to planting area before July 15, and harvesting after winter solstice. The water chestnut planted hollow cabbage or empty field in the planting area from March to June of the second year; lobster seedlings were put into the planting area in August and September after the cultivation of water chestnut. When the lobster seedlings were put into the ring lobster pond, the water level of the ring lobster pond was not higher than that of the water chestnut planting area, so that all the shrimp seedlings were put into the ring pond; the special feed for small lobster was put into the next March, and the special feed for small lobster was put into the end when the water chestnut was planted in July of the second year. The invention has the advantages that the crayfish can loosen soil, remove insects, weeds and fertilize water, purify aquaculture water, provide living and shelter places for crayfish, and improve the quality of crayfish breeding.

一种稻田种荸荠养龙虾方法
本专利技术专利涉及一种稻田养龙虾的方法,特别涉及利用稻田里套种空心菜、荸荠及养龙虾的方法。
技术介绍
现有技术中,是利用稻田一边种植水稻一边养龙虾,此方法虽好,但形式过于单一,不利开展多种作物的混合经营,同时,为防止水稻虫害需要大量使用农药,农药落入水中,又会造成龙虾体内农药超标。
技术实现思路
本专利技术提供一种稻田养龙虾的循环种植方法,龙虾为空心菜、荸荠松土去虫除草追肥,双莲荸荠净化养殖水体、还为小龙虾提供了生活和遮蔽场所,为小龙虾创造了良好的生长环境,减少了农药的用量,提高小龙虾养殖品质。实现本专利技术的技术方案是,一种稻田养龙虾的循环种植方法包括稻田改造、作物种植、小龙虾养殖;所述稻田改造,包括环形龙虾池开挖、中间种植区平整,沿稻田边沿开挖宽不小于2米的、深不小于1米的环形龙虾池,在所述环形龙虾池中间设有平整的种植区;所述作物种植,荸荠4月上中旬假植育苗,7月15日前移栽至种植区、冬至后收获荸荠,第二年3月至第二年6月在种植区种植空心菜或空田;所述小龙虾养殖,荸荠种植后,8-9月份投放龙虾虾苗,投放时,环形龙虾池水位不高于荸荠种植区, ...
