一 玉米是我国粮食生产中的主要作物之一,也是一种比较高产的粮食作物,常年播种面积与总产量约占全国粮食面积和总产量的12—13%。近几年来,玉米的生产是稳步上升的,1965年的单产和总产均已超过历史最高水平。尤其可喜的是,无论在南方、北方,或在高产区、低产区,都出现了一批大面积、大幅度的增产县。据统计,全国亩产达到300斤以上的县,计有210个。河北省遵化县386,000亩玉米,亩产600斤;山东省黄县283,000亩玉米,亩产500多斤;山西省太谷县127,000亩玉米,亩产500斤;上海市崇明县190,000多亩玉米,亩产600斤。特别是出现了许多持续稳产高产的社、队。例如:山西省昔阳县大寨大队,1954年玉米平均亩产256斤,1958年以来一直稳
Corn is one of the main crops in China’s grain production. It is also a relatively high-yielding grain crop. Its perennial sown area and total output make up 12-13% of the national grain area and total output. In recent years, the production of corn has risen steadily. Both the yield and the total output in 1965 surpassed the highest level in history. What is particularly gratifying is that a large number of large-scale and sharply-increased counties have emerged in both the southern and northern areas or in areas with high yield and low yield. According to statistics, there are 210 counties in the country that have produced over 300 kilos of mu per mu. 386,000 mu of corn in Zunhua County of Hebei Province with a yield of 600 kg per mu; 283,000 mu of corn in Huang County of Shandong Province with a yield of 500 kilos per mu; 127,000 mu of corn in Taigu County of Shanxi Province with a yield of 500 kg; 190,000 mu of corn in Chongming County, , 600 kg per mu. In particular, there have been many clubs and teams that have sustained steady and high yields. For example: Xizang County, Shanxi Province Dazhai Brigade, 1954 average yield per mu 256 pounds, 1958 has been steady
