把传统的施肥、投饵、调节水质和防病技术有机结合,并加以改进和完善,才能提高综合防治鱼病的效果。1 改进投饵施肥技术 逐步推广冬季清塘、冬季投种、冬季施足基肥。在常规“四定”(定点、定时、定质、定量)投饵的同时,做到以草养鱼和推广配合饲料,以青代精,精粗结合。精饲料以饼、糠麸混合或交替使用,以饼类为主;青饲料以苏丹草、黑麦草为主。投饵方法实行“两头精、中间青”。精饲料为摄食性鱼体重的5％左右,青饲料为草鱼、团头 The traditional fertilization, feeding, regulating water quality and disease prevention technology organic combination, and to improve and perfect in order to improve the comprehensive prevention and treatment of fish disease. An improved feed fertilization technology Gradual promotion of winter clear pond, winter cast, winter enough to apply base fertilizer. In the conventional “four fixed” (fixed-point, timing, qualitative, quantitative) feeding at the same time, so that fish and grass to promote grass compound feed, green fine, fine combination. Concentrated feed to cakes, bran mixed or used interchangeably to the main cakes; green feed to sudangrass, mainly ryegrass. Feeding practice “two fine, middle green.” Concentrated feed is about 5% of the body weight of ingested fish, grass fodder is grass carp, head
