摘要
本文研究了麦稻两熟制品种、措施、环境３个方面的增产潜力和综合增产潜力，并对其能量平衡、土壤养分和有机质平衡以及经济效益作了分析。提出发挥品种、措施、环境的综合技术作用是实现麦稻两熟高产的重要途径，并提高生态经济效益的技术发展方向。
This paper deals with the potential of crop varieties, cultural practices and environments or their combination for increasing production in the rice-wheat double cropping system.Ihe energy balance,the balance of soil nutrients and organic matter and economic benefits were analysed.The results suggest that the combination of crop varieties, cultural practics and environments is a technical direction to achieve high yields in the rice-wheat double cropping system and to increase the ecological and economic benefits.
