在主施氯化铵的混养池塘中鲢、鳙生长的研究

THE GROWTH OF SILVER CARP AND BIGHEADIN POLYCULTURE PONDS FERTILIZED MAINLY WITH AMMONIUM CHLORIDE

  • 摘要: 以鲢、鳙为主养鱼类的混养池塘中,在各种条件基本相同的情况下,设计了4种以氯化铵为氮源、1种以碳铵和尿素为氮源、1种以有机肥为肥源的追肥处理,旨在查明6种追肥处理对鲢、鳙生长的影响.试验结果表明;氯化铵能促进鲢、鳙快速生长;N与P2O5,的比为2:1时生长最佳.分析讨论了6种追肥处理池塘中鲢、鳙在不同养殖阶段的生长特点,并提出了进一步增产的措施.

     

    Abstract: Growth of the silver carp(Hypophthalmichthys molitrix)and bighead(Aristichthys nobilis)were studied in polyculture ponds with the two fishes as main cuIture species.Six fer-tilization regimes were employed among which four used ammonium chloride one usedammonium bicarbonate and urea,and one used organic manure as nitrogen source.The daily absolute growth,daily growth rate, instantaneous growth rate, relative growth rate inlength and weight, and condition factor were detennined for different periods of the growthseason,The resuIts indicated that ammonium chloride was a pond fertilizer with good quality and promoted the growth of the silver carp and bighead.Best growth was achieved whenthe ratio of N/ P2O5 in the fertilizer was about 2.Supplemental application of potassiumfertilizer did not improve the growth of the two fishes.
