小麦、玉米和水稻是世界三大粮食产物,玉米的种植面积仅次于小麦和水稻,但是玉米的产量却居三大谷物之首。玉米是我国主要的粮食作物之一,对保障国家粮食安全作出了突出贡献。受到自然气候的影响,我国粮食品种结构不平衡的问题仍然存在,为扩大玉米的种植产量,对玉米的种植条件进行分析与探究。 Wheat, corn and rice are the world’s three major grain products. Corn is second only to wheat and rice, but corn yields are among the top three cereals. Corn is one of China’s major food crops and has made outstanding contributions to the protection of national food security. Affected by the natural climate, the unbalanced structure of grain varieties in China still exists. In order to expand the planting yield of corn, the planting conditions of corn are analyzed and explored.
