摘要：【中文】本申请提供了一种生态水循环盐碱地改善方法，在稻田中设计一种水循环生态养殖系统，实现以渔治碱，来改善稻田盐碱问题。通过稻田水循环系统，将粪汇集粪便池中，通过水泵分散到每一块稻田中，被水稻吸收和改良土壤，降解盐碱地危害，通过养殖鱼和蟹，利用生物特殊的生理器官和排泄物，可降解盐碱含量。通过生态水循环技术的实施，不但可以洗盐、降盐，又可以改良盐碱地突然环境，提高土壤有机质，实现水稻品质和产量的双丰收。 【EN】The application provides an ecological water circulation saline-alkali soil improvement method, a water circulation ecological breeding system is designed in a rice field, and the purpose of controlling alkali by fishing is achieved to improve the saline-alkali problem of the rice field. Through paddy field water circulation system, collect excrement urinal with the excrement, in dispersing each paddy field through the water pump, absorbed and improved soil by the rice, degradation saline and alkaline land harm, through breeding fish and crab, utilize biological special physiology organ and excrement, degradable saline and alkaline content. By implementing the ecological water circulation technology, salt can be washed and reduced, the sudden environment of the saline-alkali soil can be improved, the organic matter of the soil is improved, and the double harvest of the quality and the yield of the rice is realized.
