摘要: 采用模拟试验研究了在不同水深和施用量下,奶牛粪污降解产物对养殖水体水质的影响。结果表明,奶牛粪污降解产物对水质的影响主要表现在对总磷、可溶性磷和溶解氧的影响上,而对总氮、氨氮、影响并不规律。水体中总磷及可溶性磷的浓度与施肥量呈正相关,与水深呈负相关,且两个因素之间具有显著的交互作用。

关键词: 奶牛粪污降解产物, 氮, 磷, 水深, 施肥量

Abstract: Simulation experiment was conducted to study the effects of cow dung degradation products on aquaculture water quality at different water depths and fertilization amount.The results showed that the effect of cow dung degradation products on water quality was mainly reflected in the effects on total phosphorus,soluble phosphorus and dissolved oxygen,but not on total nitrogen,ammonia nitrogen.The concentration of total phosphorus and soluble phosphorus in water was positively correlated with the amount of fertilizer,and negatively correlated with water depth,and there was a significant interaction between the two factors.

Key words: cow dung degradation products, nitrogen, phosphorus, water depth, fertilization amount
