The outstanding sand-fixed plants andThe outstanding sand-fixed plants and important source of future oilimportant source of future oil
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
a kind of fasciculate shrub ， 3-8metres high
with scalelike leaves.
1.Morphological Feature
“The king of desert plants” --- Haloxylon ammodendron
PhotophilousStrong drought resistanceSalt resistanceIt can not only grow in arid barren desert area, but also on middle or light degree salinized soil
2.Biological characteristics
Cistanche Deserticola
Sand control and wind prevent
Economic value
3.Application Value
Chinese herbal medicine
There are many lateral roots, on which one plant parasitize, named Cistanche DeserticolaIt is precious Chinese herbal medicine and has economic value
Sow the seedsTransplant young seedlings Sandy soil with mild salinization or fine sand
soil should be chose to cultivate the young plant
4. Planting Method
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
“Guardian of the desert” --- Nitraria sibirica
Strong adaptability Drought resistancesalt endurance Cold resistance
2.Biological characteristics
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 diseasesThe stone can be used to extract oil
3.Application Value
It has many good economic and ecological benefits
Sow the seedscuttage 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.
4. Planting Method
Deciduous shrubs or small arbor, 5meter high
1.Morphological Feature
“The North oleic Camellia of China” ---Shinyleaf Yellowhorn
2.Biological characteristics
Photophilous tree species Strong adaptabilityDrought tolerant
Extract diesel oil
3.Application ValueThe oil content of the Shinyleaf Yellowhorn seed is amounted to 50%-70%,And that of the stone is 72%,the amout is more than one time as much as the rapeseed
The biennial breedding variety has about 200 kg seeds per mu, while the high-yield cultivation can produce 2000-2500kg seeds per mu which can be calculated to 700-1000 kg or more biodiesel.
Extract edible oil
3.Application Value
The oil can be used for the prevention and treatment of hypertension, high cholesterol and other diseases
The sowing time is spring and autumn. Sows the seeds directly.
4. Planting Method
sow the seeds
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 stoneIt will be more helpful for the desert plant
cultivation by using the modern advanced network technology and
sensor technology.
