玉米是黑龙江省主要的高产作物之一,栽培面积约占粮食作物总面积的1/4强;产量占粮食总产量的35—45%,单位面积产量相当全国玉米平均产量的102.3%,总产量占全国玉米总产量的8.73%。栽培的品种以马齿种(黄金塔、红瓤子为代表)、硬粒种(火苞米、长八(足尚)、小金黄、牛尾黄为代表)、中间型(白头霜、金顶子为代表)等三个籽粒质地生态类型在全省各地做有规则的分布。品种生产水平较低。迅速地提高玉米品
Corn is one of the main high-yield crops in Heilongjiang Province. The cultivated area accounts for about one quarter of the total area of food crops. The output accounts for 35-45% of the total grain output. The yield per unit area is equivalent to 102.3% of the average corn output in China. The total output Accounting for 8.73% of the national total corn output.
