摘 要:通过对36个饲草品种适应性栽培技术,营养分析、饵料系数、喂鱼效果及鱼食后其残渣和鱼的排浅物沉入塘底,提高塘泥养分,用塘泥垩田改土曾产作用等方面的研究比较。筛选出产草量高,营养好,鱼喜食的4种适宜沿海农区的主体品种(多花黑麦草,杂交狼尾草,苏丹,紫花苜蓿)和四个搭配品种(白三叶,小米草、黑麦、细绿萍)。提出周年供草的品种搭配模式,品种种植比例,以及草和鱼塘面积的比例。从而得出一套较完整的周年供青模式和相应的高产栽培、换茬接种技术。Adaptability, cultivation, and nutrition of 36 species or varieties of forages were studied. Their bait food coefficient, effects on feeding fish and crop yield after applying fishpond sludg to the fields were also evaluated. Lonlium multilorum, a hybrid of penisetum americanum and P. purpureum, Sorghum sudanense and Medicago sativa showed high yield and nutrition, good palatability for fish, and adapted widely in the coastal area. Trifolium repens, E.chinochlou, Secale cereale and Azolla filiculoides grew well with the above species in the mixed pasture. Sowing rates, establishment and management for each species were presented, Forage budget for the fish through a year was recommended.
