【摘要】 试验研究结果表明,把不同熟期的品种组装起来进行增温和分期种植,有利于显示品种的各自优势,加快早熟品种生育进程、提早青嫩鲜穗采收时间;提高晚熟品种的光、水、热等资源利用效率,增加生物产量。特别是品种南种北移,既能提高青嫩鲜穗产量,也不影响鲜产品质量。实现南种科学北引和早中晚熟品种合理搭配,是提高特种玉米生产效益的有效措施。表5,参6。更多还原

【Abstract】 The results showed that the mixture of hybrids with different maturity facilitated to predominance of each hybrid,and accelerated the developmental process.The harvesting dates were earlier than the normal planting.Biomass,light and water use efficiency was increased in late maturity hybrid.The mixture of hybrids is an effective way to enhance the production benefits in specialty corn.更多还原
