How to Select Sea Buckthorn Seeds? A Detailed Guide to Raising Seedlings

Sea buckthorn is a plant of the genus Hippophae in the family Elaeagnaceae, also known as seaberry, and is a deciduous shrub or small tree. The fruit of sea buckthorn is high in vitamin C and is called the "king of vitamin C". Sea buckthorn tolerates poor soil, cold and drought, and has strong root-sucker sprouting ability, with high ecological and economic value, and is an important pioneer tree species for afforestation and an economic forest tree species in arid areas. So how do you select sea buckthorn seeds? What seedling raising methods are there? Let's take a look together with the editor below.

1. How to select sea buckthorn seeds?

To grow sea buckthorn, you should choose good varieties, and seed selection is very important; fresh seeds free of pests and diseases are the first choice.

Before spring sowing, soak the seeds until they swell, and sow in rows with a row spacing of 10-15cm and a depth of 3cm. Seedlings emerge after 1 week; when the first pair of true leaves appears, start thinning, and at the fourth pair of true leaves, thin a second time, keeping a plant spacing of 5cm. Autumn sowing is best done in late autumn; after sowing, cover the bed surface, water and let it freeze in winter, and seedlings will emerge the following year.

2. What seedling raising methods are there for sea buckthorn?

1. Sowing time

For the sea buckthorn sowing season, other than winter, sowing can be done in the other three seasons, and the best sowing season is spring. When the soil temperature in spring reaches 10°C, it is time for the seeds to sprout, and sowing begins when the soil temperature is 14-16°C.

2. Sprouting promotion

Before sowing sea buckthorn, the seeds should be soaked to promote sprouting. First disinfect with a 0.6% potassium permanganate aqueous solution, then carry out the sprouting treatment. The method is sand mixing: soak in warm water at about 50°C for 24-48 hours, remove, mix with wet sand at a ratio of 1:3, place in a sunny, wind-sheltered spot, cover well to increase temperature, and maintain the temperature before sowing. Within five or six days, turn once every other day, then turn once a day after that; at 10-15 days, when 2/3 of the seeds have split open, they can be sown.

3. Sowing and seedling raising

Generally the sowing width is about 15 cm, the sowing row spacing is about 25 cm, and the bottom of the furrow must be level. Scatter the seeds evenly within the sowing width, cover with fine sandy soil about 2 cm, and press appropriately so that the soil and seeds make full contact. At sowing, water thoroughly, and after the soil dries, level the bed surface again. After sowing, cover with grass to prevent strong wind and rapid water evaporation from drying out the soil. After the seedlings grow, gradually remove the covering grass to avoid sunscald on the tender seedlings. After sowing, spray water to keep the soil moist; after 5-7 days most young seedlings emerge, and in about 15 days the young seedlings come up completely.

The above is an introduction to sea buckthorn. Sea buckthorn fruit is rich in nutrients, is in great demand on the market, and offers fairly good growing profits. When growing sea buckthorn, farmers must master the seedling raising techniques well.
