摘要:
水作为动物赖以生存的基本要素，对动物健康非常重要。本实验旨在通过对动物生活区的水质进行监测，进而为动物饲喂管理提供科学依据。经过对苑区内5处采样点pH、总磷(TP)、总氮(TN)、细菌总数(TVC)及粪大肠菌群(COLI)等水质指标进行监测，发现6月份氮磷含量为三个月中最高，平均值分别达到1.19 μg/mL与0.36 μg/mL，这主要是因为6月份时水中溶解氧降低，大量水生植物与鱼类死亡，植物分解时，会产生大量的氮磷；5月份的细菌总数和粪大肠菌群为三个月中最高，5月份细菌总数的含量是4600个/mL；5月份的粪大肠菌群含量231,500个/L，这主要是因为6、7月份雨水增加，对水中的细菌总数与粪大肠菌群数量起到了稀释作用。
As the basic element for maintaining life, water is very important for keeping animal healthy. The test was held in the Milu Park core-protection area. There are 5 sampling sties have been selected, and the 5 indexes included pH, TP, TN, TVC and COLI have been assayed. The result shows the lower dissolved oxygen lead abundant hydrophyte and fish died, that lead the TP and TN raised up to the top with 1.19 μg/mL and 0.36 μg/mL respectively in the June. The TVC and COLI were peaked on May, with 4600 in per mL and 231,500 in per mL respectively for the natural rainfall increase dilute above 2 indexes.
