新银合欢是一种速生乔木豆科树种,是热带优良的饲料、燃料、木料及肥料等多种用途的植物。我院于1961年从中美洲引进,1965年在华南各地试种推广。经多年试验认为:它适应性强、耐割、嫩茎叶产量高,每亩达3000～4000公斤。据美国夏威夷大学研究,认为新银合欢的饲料蛋白质营养价值高,其氨基酸含量优于苜蓿,并富含胡萝卜素及维生素。为了解新银合欢在华南地区栽培条件下的营差价值,我们从1982年起,对其营养成分进行初步的分析研究。一、分析内容 (1)不同营养器官的营养成分分析 Acacia is a fast-growing tree legume species, is a tropical tropical feed, fuel, wood and fertilizer and other purposes plants. Our hospital was introduced from Central America in 1961, and was popularized in all over South China in 1965. After many years of experiments that: it is adaptable, cut-resistant, high yield of tender stems and leaves, up to 3000 ~ 4000 kg per mu. According to the University of Hawaii, the research shows that the feed protein of New Acacia is of high nutritional value, has better amino acid content than alfalfa, and is rich in carotene and vitamins. In order to understand the malpractice value of New Acacia cultivated in South China, we have conducted a preliminary analysis of its nutritional components since 1982. First, the analysis content (1) Nutritional components of different vegetative organs analysis
