Design Principals

The Principals of hippophae roots.

Prevent Windstorms and Fasten Sand(A):

The roots of hippophae grow through lateral and longitudinal , and then there regenerate adventitious bud from the lateral roots and grow to be the plantlet. This process is called ratoon, a kind of asexual reproduction. The hippophae develops through this way and to consolidated sand and soil.

Improving Soil---Nitrogen Fixation(B):

Frankiaceae is a microorganism which is obligate mutualistic associationin with the non legume root nodules.It can infect the cortex of the root, and develop to be the vesicle. The vesicle own the strong ability of the nitrogen fixation.

Improving Soil--Conversion of Organic Componds(C):

The root also can translate the ineffective inorganic and the organic in the soil to the effective organic componds. At the same time, it can raise soil porosity, and improve soil water storage capacity.

The water storage of the itself is also capable. The advanced phloem parenchyma and the larger intercellular space make it have high water holding capacity. According to the picture left, it may adjust the phloem parenchyma to adapt to different environment .

Life’s Principals

EVOLVE TO SURVIVE

Hippophae have lived on earth for more than two hundred million years.only to continue to develop and adapt to the new environment can be able to survive.

ADAPT TO CHANGING CONDITIONS

Hippophae in different regions ，have the different type of the plant traits and growth habits. Hippophae is constantly changing to adapt to the changing environment.

BE RESOURCE EFFICIENT

Root nodule formation of Hippophae can convert soil mineral, organic matter, and insoluble inorganic compounds into an easily absorbed form, which can effectively improve the soil fertility. Hippophae convert the difficult use resources into the be able use resources , greatly enhance the utilization of resources.

USE LIFE-FRIENDLY CHEMISTRY

Root nodules of Hippophae can be used to fix nitrogen molecules in the air, to provide the nitrogen needed for plant growth, and to avoid the use of artificial fertilizers.
