本文从鱼种产量,经济效益,能量利用率,氮素利用率,鱼种的肉质等诸方面对主施沼液和主施鸡粪培育鱼种与套养蚌种进行比较研究。结果表明,主施沼液者佳,主施鸡粪者差。作者在试验过程中对肥饵和水质定期进行了测定,指出主施沼液培育鱼种是一条简单易行,成活率高,质量好,成本低,效益高的途径。 In this paper, the main biogas slurry and host chicken manure cultivated species and reared mussel species were comparatively studied in terms of fish production, economic benefits, energy utilization rate, nitrogen utilization rate and meat quality of fish species. The results show that the main biogas slurry is good, the main facilities are poor chicken manure. During the experiment, the authors measured the fertilizer bait and water quality on a regular basis. It is pointed out that the cultivation of fish species by the host biogas slurry is a simple and feasible method with high survival rate, good quality, low cost and high benefit.
