The difference between sea buckthorn seed oil and sea buckthorn fruit oil: 1, sea buckthorn seed oil is mainly extracted from sea buckthorn seeds, while sea buckthorn fruit oil is extracted from sea buckthorn pulp. 2, sea buckthorn seed oil contains more unsaturated fatty acids, linoleic acid, linolenic acid, oleic acid, accounting for more than 85%, focusing on liver health and protection of the liver; sea buckthorn fruit oil contains more 27% of palmitoleic acid, more than the seed oil compared to the vitamin E, carotenoids. And the color is brownish red, and the taste is relatively thick, focusing on stomach and stomach protection.
Seabuckthorn is a kind of deciduous shrub, which is characterized by drought-resistant, sand-resistant and can survive on salinized land, so it is widely used for soil and water conservation. Large quantities of sea buckthorn are planted in northwestern China for desert greening.
Seabuckthorn planting technology
1、Propagation
(1)Seed Propagation
before sowing in the spring, the seeds will be soaked, and rows will be planted in strips at a spacing of 10~15 centimeters, with a depth of 3 centimeters. Seedling emergence after a week, when the emergence of the first pair of true leaves, began to inter-seedling. When the fourth pair of true leaves appeared, the second inter-seedling, plant spacing to maintain 5 centimeters. Autumn sowing should be carried out in the late fall, after sowing beds covered, winter watering to seal the freeze, the next year's seedlings.
(2) cuttings propagation
Cuttings selection of medium maturity of the growing branches, the insertion period to mid-June to the end of August is appropriate, insertion of rows of plants spacing of 10 ~ 15 cm × 5 ~ 10 cm. The next spring transplantation, row spacing for 30~60 cm × 15~17 cm. With 1~2 years asexual propagation seedlings afforestation, planting density to dense planting is good, row spacing 4 meters × 2 meters. For types or varieties with different fruit ripening periods, they can be planted in pieces to facilitate management. When planting, pay attention to the reasonable ratio of male and female, generally 8 female plants with 1 male plant.
2, field management
In order to improve the soil fertility, we should pay attention to the mid-ploughing and weeding, sea buckthorn is more sensitive to phosphorus fertilizer, and we can apply calcium superphosphate as appropriate to benefit the growth of plants. The growth of sea buckthorn is divided into four stages: seedling period, fruiting period, fruiting period and decline period. In two years after planting, the underground growth is the main part, and the above ground part grows slowly. 3~4 years, the growth is vigorous, and it starts to blossom and bear fruits. Adult sea buckthorn tree is 2.0~2.5 meters high, and its crown is 1.5~2.0 meters. The fifth year enters the peak fruiting period. Due to the different soil conditions and management, the time to enter the decline period is different, generally the tree enters the decline period after 15 years of age.
(1) Planting density
220 plants per mu (667 square meters), with spacing of 1.5m×2.0m. Sea buckthorn tree is female and male heterozygous, the ratio of female and male is 8:1, the specification of the tree hole depends on the size of the sapling, generally 35 centimeters in diameter and 35 centimeters in depth. Seedling age is two years old shoot cuttings are good.
(2) Growth pruning
The sea buckthorn grows up to 2.0~2.5 meters high when cutting the top. The main point of pruning is to hit the horizontal not to hit the smooth, go to the old and keep the new, prune at the dense place, keep the strong branches in the lack of space, clear the hollow and cut off the bottom of the pruning, and the crown will be complete with high yield.
