【摘要】 根据多年的调研和试验资料，利用非线性积温模型，模拟了对虾幼体各发育阶段所需天数与水温的关系。在此基础上研究确定了亲虾产卵孵化期的气候决策模式；并应用模式计算出了我市亲虾产卵孵化的适宜时段。为亲虾适宜产卵孵化期的决策提供了科学方法更多还原

【Abstract】 The relations between the days required for the development of various young stages of prawn and the water temperature were studied by simulation using non linear accumulated temperature models and experimental data. Climatic decision model for selecting spawning and hatching time was developed. Appropriate period for spawning and hatching of prawn in Yancheng, Jiangsu Province, was calculated by this model, which provides scientific basis for arranging activities in young prawn raising.更多还原
