摘要
本文通过对水体中氮素营养条件的研究,分析了水体中不同氮素对水葫芦生长的影响,从而为福建省水葫芦的综合治理提供科学依据。结果表明:在水体氮浓度为25~30mg·L^1的范围内,水葫芦生长情况最佳,高于或低于这个范围,水葫芦的生长发育均受到不同程度的抑制。
This study investigated both the distribution of and the relationship between status and water quality in infestations of malignant water hyacinth. The effects of different nitrogen levels on water hyacinth were measured and used as a solid scientific base to develop an integrated control system for water hyacinth in Fujian Province. The water hyacinth grew best in water with a nitrogen concentration between 25 -30 mg L^-1. The growth of water hyacinth declined if the concentration was higher or lower than this range.
