Aquaculture Water Quality Improvement by Ecological Remediation Integration Technology in Ecological Agriculture District
摘要
Abstract
The current ecological situation of aquaculture water quality in Wushe (Songjiang District,Shanghai City) district is not upto mark.In the present study,characteristics and basic information of ecological agricultural park were first investigated.Ecological remediation integration technology,including aquatic plant purification and aquatic economic crops floating bed were used to improve the aquaculture water quality in this district.After operating for a period of defined time,effect of the integration technology on quality improvement of aquaculture water was estimated.The results showed significant improvement in the aquaculture water quality at experimental site with removal rates of CODCr TN and TP were 73.5％,24.9％ and 67.4％,respectively.In addition,the purification effects of ecological remediation integration technology and individual technology were compared.The results indicated that the integration technology was better than individual technology,as removed TN,TP,Nitrite nitrogen and CODCr at the rate of 13.7％,40.1％,78.7％ and 114.4％,respectively,higher than that of individual technology.In addition,water spinach which was grown on aquatic economic crops floating bed was harvested at regular time intervals.The total harvest weight of water spinach was 11 907 kg,which could achieve good economic benefits.A small parts of the water spinach were transplanted to crab ponds.The transplanted water spinach could not only serve as food source for crab,but also purify the water quality in crab ponds,which could maintain the biological diversity in aquacultural ponds and coincidence with production mode of circulation ecological agriculture.关键词
