How to grow sea buckthorn berries? Latest planting techniques and methods tutorial shared
Sea buckthorn is a drought-tolerant, wind-and-sand-resistant shrub that can survive on saline-alkali land, so it is used for windbreaks, sand fixation, and soil and water conservation. At present, it is widely planted in northwestern China for greening deserts and gobi areas. The sea buckthorn berries it produces have an extremely high vitamin C content and also have the effects of lowering cholesterol and relieving angina, and are widely used in the food and pharmaceutical fields. So how should sea buckthorn berries be planted? Let's take a look together.
1. Preparation work
Sea buckthorn is a sun-loving tree species that needs light. It is not strict about soil requirements and can grow normally in gravelly soil and mildly saline-alkali soil, but it does not like overly sticky heavy soil. It is not strict about temperature requirements and can survive at -50 degrees to 50 degrees Celsius. When planting, combine it with land preparation, apply 2500-4000 kg of decomposed farmyard manure per mu, apply it into the bottom of the ridge when ridging, and be careful to mix it evenly with the soil to avoid root burn.
2. Seed germination
Before sowing, choose fresh seeds free of pests and diseases. Sowing can be done in spring, summer, and autumn, but spring is preferable. Generally, the sowing rate is about 4 kg per mu. In order to improve the germination rate, seed soaking and germination should be done before sowing. Put the seeds into a potassium permanganate solution and soak for 2 hours, then remove them and carry out germination. Generally, the mixed-sand method is used: mix the seeds with wet sand at a ratio of 1:3, pile them in a sunny place, cover with plastic film to keep warm and moist, and generally turn them once a day. When one third of the seeds have cracked open, they can be sown.
3. Sowing and raising seedlings
⟦NL>To facilitate seedling growth and management, sowing should adopt wide row spacing and a wide sowing width. Sow the seeds evenly into the furrows, then cover with 2-3 cm of soil, and press gently with your hand so that they make full contact with the soil. Water thoroughly once before sowing, and after the soil dries, level it and sow. After sowing, cover with rice straw to help emergence. As the seedlings emerge, remove it gradually to avoid sunscald. For spring sowing, spray water to maintain moisture. Generally, seedlings emerge in one week, and full emergence occurs in half a month.4. Cultivation management
The planting density should be determined according to the vigor of the variety and tree. In order to improve pollination quality, one row of pure female plants and one row of mixed male and female plants should be planted alternately. When planting, dig the planting pits well, apply fertilizer, and water. In the first few years before fruiting, do a good job of cultivating and weeding. In areas with relatively good conditions, some urea can be applied after rain to promote growth. In spring, do light pruning and cut off excess dead branches and diseased and pest-infested branches, so as to improve the plant's air circulation and light penetration and reduce pest and disease damage. If pests and diseases occur, spray pesticides promptly for treatment.
