苏鲁两省芦苇荡养鱼技术的调查研究

AN INVESTIGATION OF FISH-FARM TECHNIQUE IN REED MARSHES IN JIANGSU AND SHANDONG PROVINCES

调查了苏鲁两省芦荡养鱼的部分单位。采用科学的管理,灌水和施肥措施,在芦荡内养鱼,芦苇和鱼都获丰收。一、年年获得丰收。由于在芦苇荡内养鱼能充分利用土地、光、热资源、鱼、芦年年获得丰收。二、芦苇荡内养鱼增产原因。 1.有水的芦苇荡是鱼栖息的好场所。 2.芦苇叶是鱼的好饲料。 3.鱼类是芦苇的好肥料。 4.通过挖养鱼沟改善了芦苇荡内的光照、温度和通风条件。三、芦苇荡内养鱼的技术。 1.挖集鱼沟。 2.选择鱼种。选草鱼、鳊、鲤、鲫、鲻、鲢等。 4.科学挖水。春天湿、夏天浅、秋天满、冬天干。

We have made an investigation into the fish-farm technique in reed marshes of institutions and units in Jiangsu and Shandong Provinces. It is found that the yield of both fish and reed can be rich with scientific management, adequate irrigation and fertilization. Growing fish in reed marshes can make full use of land, sunlight and heat. Reed leaves are good feed for fish, and fish manure is a good fertilizer for the reed. The main measures are:(1) digging ditches, which can improve illumination, temperature and ventilation of the marshes;(2) selecting suitable fishes, such as grass carp, the crucian and bream; and(3) water controll, i. e., the marshes are wet in spring, with shallow water in summer, full in autumn, and dry in winter.
