Hippophae rhamnoides.L, also known as acanthopanax senticosus, is an Elaeagnus seabuckthorn shrub or small tree, is a positive tree species, dioecious, up to 10 meters, the most common for 1-2 meters, was Clustered. Lush foliage, fast growth. Triennial sprout saplings, 1.1 meters high, 2 cm in diameter, crown width of 1.5 meters. Roots developed. Adaptable, lax requirements of climate, drought and cold weather can withstand the requirements of the soil is also low, drought-resistant barren and water-wet, in the valleys, banks, sloping bottom, Liang Gouding and desert can grow on the wasteland, However, poor growth on the clay in almost all parts of our province are distributed. Fruit sweet and edible, oil content of seed 14-16%, the leaves can be used as horse, sheep feed, branches flammable, firepower, high output of firewood (in Qin’an County, annual output of more than 600 kilograms per mu of firewood). With seeds, cuttings and sprouting seedlings can reproduce, soil and water conservation is good soil shrub species; also solve the rural
