在水源紧张、水质盐度高、碱度大的池塘中,采用合理混养,适度密养与延长鱼类生长期相结合,有机肥、无机肥与投饵相结合,传统养殖技术与现代化养殖手段相结合的综合养殖技术措施,使池塘单产量增加4.5倍以上,产值增加10倍以上,在我区首次突破千亩池塘平均亩净产250公斤的大关。天津市南郊区地处九河下稍,属退海地,池塘氯化物含量常年在1-3‰之间,pH值多在8-9之间,枯水季节高达9以上。由于水质差,一些养殖单位又缺乏科学的放养和管理技术,加之饵、肥紧缺,致使池塘单产很低,多年徘徊在40-90公斤之
In water stress, water salinity, alkalinity of large ponds, the use of reasonable polyculture, moderate maintenance and prolonged fish growth phase combination of organic manure, inorganic fertilizer and feeding combination of traditional farming techniques and modern culture Means a combination of integrated aquaculture technology and measures to make the pond more than 4.5 times the single output increased more than 10 times the output value in the region for the first time exceeded acres of acres of a net net profit of 250 kilograms mark. Located in the southern outskirts of Tianjin, Jiuhe River is a little back to the sea, the pond chloride content of perennial 1-3 ‰, pH value of more than 8-9, dry season up to 9 or more. Due to poor water quality, some breeding units lack scientific stocking and management techniques. In addition, bait and fertilizer are in short supply, resulting in very low yield of ponds and hovering at 40-90 kg for many years
