自从新中国诞生以来,我省玉米的种植业发生了很大变化,玉米的种植面积不断扩大,单产水平也出现了几个阶段性的提高。据统计,我省1949年玉米种植面积为1026.2万亩,占全省总种植面积的17.7%,总产86.5万吨,占粮食总产的23.8%,平均亩产83.5公斤。到1992年,玉米种植面积达到了1917.6万亩,占全省总种植面积的42.6%,总产864.5万吨,占粮食总产的51.5%,平均亩产450.82公斤。种植面积比1949年增加近1倍,粮食单产比1949年增加5.4倍,总产量增加10倍。近几年来,玉米成了带动我省粮食产量上新台阶的龙头作物。一、农家品种整理阶段建国初期,农业科研部门对省内现有的农家品种
Since the founding of New China, the planting of maize in our province has undergone great changes. The planting area of maize has been constantly expanding and the level of yield has also risen several stages. According to statistics, the area under corn planting in 1949 was 10,262,000 mu, accounting for 17.7% of the total planted area of the province with a total output of 865,000 tons, accounting for 23.8% of the total grain output with an average yield of 83.5 kg per mu. By 1992, acreage reached 19,176,000 mu, accounting for 42.6% of the total planted area in the province with a total output of 8,645,000 tons, accounting for 51.5% of the total grain output with an average yield of 450.82 kg per mu. The acreage has nearly doubled that of 1949, the grain yield has increased 5.4 times as much as that of 1949, and the total output has increased tenfold. In recent years, corn has become the leading crop that drives grain production in our province to a new level. First, the stage of finishing varieties of farmers In the early days of the founding of the agricultural research departments of the province’s existing varieties of farmers
