河蟹育苗池塘底质管理技术的初步研讨

Preliminary Studies on Management Technology of Bottom Quality in Breeding-ponds of Eriocheir sinensis

结合河蟹土池育苗实际,对育苗池塘底质的演变规律及其对育苗生产的主要影响进行了分析研讨。据此提出了强化产前准备措施、控制外源有机物入池量、消减池内沉积废物和灵活调节池水深度等实用技术要点,为有效管理苗池底质及水质提供参考。

Changing rules of bottom quality in earth-ponds of breeding Eriocheir sinensis and its basic effects on breeding production are analysed and discussed respectively based on breeding practice in details. According to these facts some practical technical keys to bottom quality management are suggested such as thorough pond preparations before breeding production, strict control of exogenous organic matter into pond, reducing and eliminating waste matter accumulated in pond timely and regulating pond water levels flexibly, etc. which provide references to adjusting and improving the bottom quality and water quality efficiently.
