黑麦草营养丰富,适口性好,且易种植,抗逆性强,适应性广,一般每亩可产鲜草5000—7500公斤左右,是目前淡水鱼类养殖的主要青饲料。生产中若按每亩水面产150公斤草鱼计算,则需用6000公斤草料,如不考虑其它陆草、水草的供给,基本上就等于1亩水面养鱼,就要1亩地面种植黑麦草,才能保证草鱼生长的青饲料来源。而且草鱼吃草量一年之中每个月需要量各不相同,还要要求黑麦草每月的生产量能与其相适应。为了减少种草面积,协调黑
Rich in ryegrass, palatability, and easy to plant, strong resistance, wide adaptability, generally produce about 5000-7500 kg of fresh grass per mu, is currently the main freshwater fish farming green feed. If the production of 150 kg of grass carp per mu of water production calculation, you need to use 6000 kg fodder, without considering the other land grasses, aquatic supplies, basically equal to 1 mu of surface water fish, we must 1 rye ground planted ryegrass, In order to ensure that grass fishes grow green feed sources. And grass carp grazing needs vary from one month to the next year, but also requires the monthly production of ryegrass to adapt to them. In order to reduce the area of grass, coordination black
