| Abstract: | Special measures should be taken for establishing agricultural eco-system because of harsh ecological conditions in the hinterland of Taklimakan Desert. The experiments had been taken for two years, and the results showed that for the 71 tested crops, the majority of them showed a poor adaptability. The yields of vegetables were lower. The ratio of input-output of energy was low, and the utility efficiency of nutrient was low in the eco-system of vegetable. Therefore, scientific field management should be taken in order to utilize land resources efficiently when agricultural eco-system will be established in this region. |
