草桨养鱼,能提高水陆草料的利用率,起到投饵施肥的双重作用,但措施须得法,否则不利鱼类生长。(一)草浆制作法:使用高速打浆机(每分钟4500—5000转)打浆。先将原料投入打浆机内,然后加水(水为草重的40%),尽量将草浆打得细些,以延长草浆在水中的悬浮时间,增加鱼类摄食的机会,防止草浆在水中过量沉积,败坏水质。各种水草加工前均用漂白粉液浸泡消毒。水花生含皂甙毒素,须在草浆中加入2%—5%的食盐消除毒性,并于加盐两小时后方
Straw paddy fish, can improve the utilization of water and land forage, play a dual role of feeding and fertilization, but the measures must be law, or detrimental fish growth. (A) straw production method: the use of high-speed beater (4500-5000 rpm per minute) beating. Put the raw material into the beater first, then add water (40% of the grass weight), try to beat the straw pulp to prolong the suspended time of the straw pulp in the water and increase the chance of the fish feeding to prevent the straw Excessive sedimentation in water, corrupting water quality. All kinds of aquatic plants are bleached and disinfected before bleaching. Peanut containing saponin toxin, to be added to the straw 2% -5% salt to eliminate toxicity, and two hours after the salt
