1. The outstanding sand-fixed plants and important source of future oil Dr. Bi Yuhui Institute of Forest Resource and Information TechniquesChinese Academy of Forestry 2007.８.29

2. All countries in the world have been engaged in developing new and renewable sources of alternative energy in recent years. • But now the cultivation of the crops for biological fuel requires to occupy huge amounts of agricultural land, and excessive using crops as biological fuel will bring about a series of other issues. • The prospect of using the vast desert space and the desert plants is bright

3. “The king of desert plants” --- Haloxylon ammodendron 1.Morphological Feature • a kind of fasciculate shrub ，3-8metres high • with scalelike leaves.

4. 2.Biological characteristics • Photophilous • Strong drought resistance • Salt resistance It can not only grow in arid barren desert area, but also on middle or light degree salinized soil

5. 3.Application Value • Sand control and wind prevent • Economic value Cistanche Deserticola There are many lateral roots, on which one plant parasitize, named Cistanche Deserticola It is precious Chinese herbal medicine and has economic value Chinese herbal medicine

6. 4.Planting Method • Sow the seeds • Transplant young seedlings Sandy soil with mild salinization or fine sand soil should be chose to cultivate the young plant

7. “Guardian of the desert” --- Nitraria sibirica • It is a kind of perennial small bush with many branches,1-2metres high • The short branches often degenerate into acicular shape. 1.Morphological Feature

8. 2.Biological characteristics • Strong adaptability • Drought resistance • salt endurance • Cold resistance

9. 3.Application Value It has many good economic and ecological benefits • It is a good choice for greening and urban landscape in Saline District • The fruit with juicy flesh is edible and can be used to make vinegar and wine • The fruit can also cure some diseases • The stone can be used to extract oil

10. 4.Planting Method • Sow the seeds • cuttage It produces offshoots near the ground, which can be cut from the mother plant and be cultivated into an independent plant. When large amount of the young seedlings are needed, the cuttage can be used.

11. “The North oleic Camellia of China” ---Shinyleaf Yellowhorn 1.Morphological Feature • Deciduous shrubs or small arbor, 5meter high

12. 2.Biological characteristics • Photophilous tree species • Strong adaptability • Drought tolerant

14. 3.Application Value • Extract edible oil The oil can be used for the prevention and treatment of hypertension, high cholesterol and other diseases

15. 4.Planting Method The sowing time is spring and autumn. Sows the seeds directly. • sow the seeds

16. Summary • The desert is gigantic resource for the vast space and the plants that hasn’t been utilized. How to make full use of it is worth studying. • Cultivating the desert plant is killing several birds with one stone • It will be more helpful for the desert plant cultivation by using the modern advanced network technology and sensor technology.
