在有机养殖模式和常规养殖条件下,笔者对扣蟹养殖池水环境的变化进行了比较研究。研究发现,温度、溶解氧、PH值无明显变化,CODMn、无机氮、磷酸盐和硫化氢含量方面有机养殖池均比常规养殖池有不同程度的降低。有机养殖在提高养殖品种品质的同时,还降低了水环境污染,是今后解决水产养殖对农业面源污染的有效途径之一。
In the organic farming mode and conventional farming conditions, the author conducted a comparative study on the changes in the water environment of the crab farming ponds. The results showed that there was no obvious change in temperature, dissolved oxygen and pH, and the organic culture ponds of CODMn, inorganic nitrogen, phosphate and hydrogen sulfide decreased to some extent than conventional culture ponds. Organic farming to improve the quality of cultured species at the same time, but also reduce the water pollution, aquaculture is to solve future agricultural non-point source pollution is one of the effective ways.
