本发明公开了一种秋季繁育虾苗的方法和应用，包括稻田选择与改造、水草栽培与养护、亲本虾的选择与培育、水位与水质管理、幼虾培育共5个步骤。本发明针对现有的小龙虾幼苗繁育主要在春季，而秋季苗种繁育存在出苗晚、成活率低问题，限制了小龙虾早春上市的技术问题，根据秋季繁育的特殊性，对繁育过程中的水草选择与种植、亲本选择与培育、水位水质调控以及幼虾投食等多个关键技术上进行摸索创新，从而显著提高了秋季繁育的虾苗的产量、规格和品质，且繁育方法简单易行，生态高效，相比于春季育苗周期更短且成活率高，弥补了秋季虾苗空缺和冬季供虾不足的问题。 The invention discloses a method for breeding shrimp seeds in autumn and application. The method comprises five steps of rice field selection and transformation, aquatic plant cultivation and maintenance, parent shrimp selection and cultivation, water level and water quality management and juvenile shrimp cultivation. According to the method for breeding the shrimp seeds in autumn and application, the technical problems that existing crayfish fry breeding is mainly conducted in spring, late seedling emergence and low survival rate exist in autumn fry breeding, and the crayfish is limited to appear on a market in early spring are solved. Multiple key technologies such as the aquatic plant selection and planting, the parent selection and cultivation, wat
