玉米是重要的粮食和饲料作物之一,在全世界有着广泛的种植。随着我国改革开放的进展以及入世在即,国外品种已陆续进入我国。由于气候条件、栽培方法以及用途不同,每个国家和地区的玉米品种也有着各自的特点。多年来,对欧洲和美国部分玉米品种(主要是粮饲兼用型品种)进行了多点试验(见图表)。 Corn is one of the most important food and feed crops and is widely grown throughout the world. With the progress of China’s reform and opening up and accession to the WTO, foreign varieties have gradually entered our country. Due to climatic conditions, cultivation methods and uses, maize varieties in each country and region also have their own characteristics. Over the years, several trials have been conducted on some corn varieties in Europe and the United States, mainly for food and agriculture (see chart).
