Abstract:

To realize grain security has always been the cardinal task in the process of Chinese nation seeking for survival and development. China Food Security Research Center of China Agricultural University proposed “‘123, 234’ Grain and Feed High Yield Projects” in 1998 and has carried out a long-term research. Based on this study, the necessity, feasibility of developing high-yield agriculture was analyzed, and the strategy of ensuring food security was expounded. 3 different prospections for future grain yield increase were presented, and the major existing problems, countermeasures and suggestions for developing high-yield agriculture were briefly elaborated.

Key words: grain security, high-yield agriculture, expected yield, counter measure and suggestion

摘要：

实现粮食安全始终是中华民族生存与发展进程中的头等大事。中国农业大学中国粮食安全研究中心1998年提出了以发展高产保障粮食安全的“‘123,234’粮饲超高产工程”,并开展了长期研究。在该研究基础上对发展高产农业保障粮食安全的必要性、可行性进行了分析,对发展高产农业保障粮食安全的战略构想进行了阐述,提出了未来粮食增产的3种不同预期,并从高产农业发展中存在的主要问题、发展对策和建议等几个方面进行了简要阐述。
