随着养鱼业的发展,鱼类饲料价格日益增长,广大养鱼户迫切需要引进高产优质饲料作物,以达到由草代料,降低饲料成本之效。近年来我国科研单位引进试验成功一些养鱼饲料,现介绍如下: (1)松香草,又名四季青。原产日本、美国以及沿海地区,属多年生宿草本植物,1990年引入我国,并试验成功,陆续推广全国各地。该草具有生长快、适应性强、耐热耐寒,产草量高且富含营养成分等特点,经湖南、四川、安徽、山东等种植试验证明,这是一种很有发展前途的新型饲草。
With the development of fish farming, the price of fish feed is increasing day by day. The majority of fish farmers urgently need to introduce high-yield and high-quality forage crops in order to reduce the cost of feed by using grass substitutes. In recent years, our country’s scientific research units to introduce some of the successful trial of fish feed, are described below: (1) pine herbs, also known as Sijiqing. Originated in Japan, the United States and the coastal areas, is a perennial herb, introduced to China in 1990, and the successful trial, one after another to promote all over the country. The grass has the characteristics of fast growth, strong adaptability, heat-resistant and cold-tolerant, high-yielding grass and rich in nutrients. The planting experiments in Hunan, Sichuan, Anhui and Shandong prove that this grass is a promising new feed grass.
