利用地埂,池坡、空闲鱼池和饲料地种植青饲料;用青饲料养鱼、养猪,草多、猪多、肥多、鱼多。种草养鱼、以草换鱼在开辟饵饲来源,增大鱼种规格,提高成鱼产量上发挥着越来越大的作用。一、资源丰富,产量较高。目前各地种植的青饲科主要有宿根黑麦草、苏丹草、稗草、爱国草、苦卖菜、各种瓜类、豆类、蔬菜等,种植技术比较简单,管理容易,产量较高。稗草亩产一般可达8,000—10,000斤,宿根黑麦草亩产1.5—1.8万斤,下半年再种苏丹草,亩产又有1万斤左右,产量高的可达2万斤。二、常年收获,四季不断。青饲料种植可以合理安排生产茬口,冬种宿根黑麦和绿肥,春种稗草和苦卖 Use of land 埂, slope, free fish ponds and feed to grow green feed; with green feed fish, pigs, grass and more pigs, more fat, more fish. Planting grass to fish, grass to change the fish to open up bait sources, increase species size, improve adult fish production play an increasing role. First, resource-rich, high yield. At present, there are perennial ryegrass, sudangrass, barnyardgrass, patriotic grass, bitter vegetables, various melons, beans and vegetables grown in various places. The cultivation techniques are relatively simple, easy to manage and high in yield. Barnyard grass per mu generally up to 8,000-10,000 pounds, perennial ryegrass mu produce 1.5-1.8 kg, in the second half of another sudangrass, there are about 1 kilogram per mu yield of up to 2 kg. Second, perennial harvest, perennial. Green fodder planting can reasonably arrange the production stubble, winter planting perennial rye and green manure, spring barnyard grass and miscarriage
