小麦是世界播种面积最大的粮食作物,1982年全世界种小麦35.9亿亩,总产9621亿斤,平均亩产267.87斤:三者分别比1948年～1952年的平均增加38.5%、152.2%和103.1%.西欧为世界小麦高产地区,荷兰、丹麦、英国、西德和法国等五个国家,1983年共种小麦1.26亿亩,总产928亿斤,平均亩产高达737斤,三十多年来,这五个国家小麦种植面积增加32.6%,总产增加2.45倍,单产提高1.63倍.我国从1949年到1983年间,小麦面积只增加28.57%,总产增加3.56倍,单产提高2.53倍.纵观国内外小麦增产情况,小麦总产量的大幅度增长,主要靠单产的提高.从发展前景看,理应也该如此. Wheat is the world’s largest sown area of ​​food crops. In 1982, the world’s wheat was 3.59 billion mu, with a total output of 962.1 billion kg and an average yield of 267.87 kg per mu: an increase of 38.5% and 152.2% respectively from 1948 to 1952 103.1% .Western Europe is the world’s high-yield wheat region, the Netherlands, Denmark, Britain, West Germany and France and other five countries in 1983 a total of 126 million hectares of wheat, with a total yield of 92.8 billion kg, the average yield of up to 737 pounds, more than thirty Over the years, the wheat acreage in these five countries increased by 32.6%, the total output increased by 2.45 times and the yield increased by 1.63 times. From 1949 to 1983, the area of ​​wheat increased only by 28.57%, the total output increased by 3.56 times and the yield increased by 2.53 times Looking at the increase in wheat production both at home and abroad, the substantial increase in the total output of wheat, mainly due to the improvement of yields, should be seen from the perspective of development.
