Status and Problems of Oasis Farming System and Key Develop Techniques in Northwest China

In Northwest China, the main characteristics of oasis farming system showed as: the coordination of farming system structure and the natural resources is significant improved, and the primary industry chains based on subsystems of farming system has been formed, as well as many great breakthrough has been made in the individual key technology of the farming system. But the current oasis farming system is facing series problems, such as the coordination among the subsystems of it is insufficient, and the systematic characteristic of the key technologies does not developed, and the connected guarantee mechanism is obviously leg behind. Construction a modern farming system that can promote the development of the economy, ecology and society is an urgent project for sustainable develop of oasis agriculture. This paper show that, constructing an integrated farming system which fit to the regional natural and social resources of oasis area, technologies as following must be improved: food chain extended technology, primary products intensive processing technology, sustainable utilize natural resources in farm land and harmful substance control technology. On the other hand, high efficient industry chains combined by different individual technologies should be developed.
