玉米种子生产，在其生产自身、栽培特性、自然条件、生产水平和生产方式等与商品粮生产有显著差异，栽培上存在问题较突出。栽培技术的优化要从投入的科学性、技术措施的针对性和配套措施的综合性入手，提高种子的产量和质量。 Corn seed production, in its own production, cultivation characteristics, natural conditions, production levels and production methods and other significant differences in commodity grain production, cultivation problems are more prominent. Optimization of cultivation techniques should start with the scientific nature of inputs, the pertinence of technical measures and the comprehensiveness of supporting measures to improve the yield and quality of seeds.
