高效鱼肥精在0.1、0.2、0.4ppm浓度下,分别比对照组(0.0ppm):水体DO平均高出0.70、1.50、1.76mg/1;24h水体初级毛生产量增加8.38、16.38、24.97mg/1·d;实验前期24h水体净生产量分别增加3.89、37.99、53.57mg/1·d,同时,实验期第2天,试验组透明度比对照组明显下降。
At the concentration of 0.1, 0.2 and 0.4ppm, the efficiency of fish fat fertilizer was 0.70,1.50 and 1.76mg / 1 higher than that of the control group (DO: 0.0ppm) The primary gross production increased 8.38,16.38,24.97mg / 1 · d; the net production of water body increased by 3.89, 37.99 and 53.57mg / 1 · d respectively in the early pre-experiment period, and at the same time, On the second day, the transparency of the experimental group was significantly lower than that of the control group.
