二年生白花草木樨(Melilotus alba Desr)是一种耐瘠、耐旱、抗寒的绿肥及饲料作物,适应性很强,春、夏、秋均可种植栽培,适用于间、混、套、复种。它在我国已有悠久的栽培历史,建国以来,发展很快,目前已成为我国重要的绿肥(牧草);美、苏等国亦广为种植,苏联近年来并有较大的发展。 早在1926年美国伊利诺州农业试验站的A.L.Whiting和Richnond已详细地分析了二年生白花草木樨不同生育时期,各器官的养分含量。但其系统的生物学特性,特别是氮素的积累与运转规律的研究,国内尚无报导,国外资科亦未见到。
The perennial Melilotus alba Desr is a barren, drought-tolerant and cold-resistant green manure and feed crop with strong adaptability. It can be planted and cultivated in spring, summer and autumn. . It has a long history of cultivation in our country. Since the founding of the People’s Republic of China, it has developed rapidly and has now become an important green manure (forage) in China. The United States, the Soviet Union and other countries are also widely planted. The Soviet Union has made great strides in recent years. As early as 1926, A.L.Whiting and Richnond of the Illinois Agricultural Experiment Station in the United States had analyzed in detail the nutrient contents of organs of two-year-old white mulberry trees at different growth stages. However, the biological characteristics of the system, especially the research on the law of accumulation and operation of nitrogen, have not been reported domestically yet.
