塔克拉玛干沙漠腹地建立农业生态体系的初步研究

Preliminary Studies on Establishing Agricultural Eco-system in the Hinterland of Taklimakan Desert

塔克拉玛干沙漠腹地生态条件恶劣 ,建立农业生态体系需采取特别的措施。两年试验表明 ,供试 71种作物大部分适应性较差 ,蔬菜产量相对较低 ;能量的产投比低 ,养分的利用率低。因此 ,在塔克拉玛干沙漠腹地建立农业生态体系时 ,应采取科学的田间管理措施 。

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.
