摘要/Abstract

摘要： 用黑白瓶测氧法对盐碱池塘浮游植物初级生产力的日变化进行了研究.结果表明,盐碱池塘浮游植物初级生产力存在着明显的日变化,其分布规律与光照、温度、浮游植物现存量等环境因子的变化是相关的.用黑白瓶法连续曝光24h测定初级生产力结果大大偏低于每次曝光2h的全天累积结果.对养鱼池而言,在10:00～14:00时曝光4h再推算全天的初级生产力较为适当.

Abstract: Daily change of the primary productivity of phytoplankton in saline alkaline ponds in Zhaodian Fishery Farm, Gaoqing County, Shandong Province, were estimated by means of dark and light bottle method, at the season of fish growth from April to September in1997. The results showed that the primary productivity of phytoplankton in saline alkaline ponds presents significant change during a day. And their distribution were correlated with some environmental factors such as light intensity, water temperature, the chlorophyll a concentration etc. The measured values of primary production in continual exposure for 24 hour with dark and light bottle methods were greatly lower than the accumulated values of exposure for 2 hour. It is proposed that diurnal production calculated by the results of exposure for 4 hour between10:00 and 14:00 was suitable in fish culture ponds.
