Abstract:

Construction of large-scale modern food demonstration base is the important measure to promote food industry development and ensure food security. This paper is aiming at providing reference of the national new 500 billion kg of grain production ability construction. Extensive literature survey combined with field investigation and the combination of qualitative and quantitative analysis were carried out to analyze the main problems of food production in Sichuan and put forward main technical countermeasures of base construction on science and technology. Rice-wheat cropping system is the dominant forms of food production in sichuan, where there is important meaning of establishing a modern food demonstration base. Its main technical countermeasures were to carry out selection of wheat and rice special varieties, exploration of new service mechanism of scientific and technological achievements transformation, integration and demonstration of high efficient production technology, rice paddies anniversary efficient planting mode and grain scale dry and processing technology integration and so on. At last, the economic benefit, social benefit, ecological benefit and industrialization perspective of supporting demonstration base construction with science and technology were analyzed. Agricultural science and technology would play an important role in modern food demonstration base constructing with outstanding standardization, intensivism, standardization and industrialization.
