水库施渔用复合肥 ,确保鱼类易消化的藻类大量繁殖生长 ,并始终处于优势种群 ,为滤食性鱼提供充足的饵料。要求渔用复合肥中的氮、磷比例科学 ,施用量合理 ,施肥方法先进 ,才能实现降低养鱼成本、增加库鱼产量和实现生态效益、经济效益双丰收的目的 The fisheries use compound fertilizers in reservoirs to ensure that large numbers of algae that are easily digestible in fish breed and grow, and are always in the dominant population to provide adequate feed for filter-feeding fish. In order to achieve the purpose of reducing the cost of fish farming, increasing the output of fish stocks and realizing ecological benefits and double-harvesting the economic benefits, it is required that the proportion of nitrogen and phosphorus in the fishery fertilizer be scientific, the dosage should be reasonable and the method of fertilization be advanced
