大麦耐瘠、耐盐碱,适应性强,全国分布面广。江苏省种植面积约占全国大麦面积的五分之一,是栽培面积最大的一个省份。前些年,生产上由于以小麦栽培措施指挥大麦生产,使产量不如小麦提高快,部分县、社就压缩大麦发展小麦。但小麦成熟晚,影响后茬棉花、玉米。近几年已有所觉察,同时随着啤酒工业的发展,大麦面积又有所扩大。我所自1972年开始进行大麦生物学特性与高产栽培技术的研究,通过十余年来的工作,逐步认识了大麦的生育特性及高产规律,现作简要归纳如下:
Barley barren, salt, adaptability, the country is widely distributed. The planting area in Jiangsu Province accounts for about one fifth of the total area of barley in the country and is the largest province in cultivation. In previous years, the production of barley produced as a direct result of wheat cultivation has led to a yield increase faster than that of wheat. Some counties and townships have contracted barley to develop wheat. However, the late maturity of wheat, cotton, corn after the impact. In recent years have been aware of, at the same time with the development of beer industry, barley area has expanded. Since 1972, we have conducted research on the biological characteristics of barley and high-yielding cultivation techniques. Through more than ten years of work, we have come to understand barley’s reproductive characteristics and high-yielding laws. The brief summary is as follows:
