Seabuckthorn planting technology
1, time
Planting seabuckthorn can be done in both spring and fall. Generally spring in April-early May, fall in mid-late October-early November, after the trees fall leaves, before the soil freezes. Seedlings planted in the fall, the next spring rooting and germination early, such as late spring drought to come when the tree has returned to normal, enhanced drought resistance, fall planting than spring planting good results.
2, planting density
300 plants per mu (666 square meters). The plant spacing is 1.5m X 2m. Seabuckthorn tree is dioecious, the ratio of male and female is 8:1. the specification of the tree hole depends on the size of the sapling, generally 35cm in diameter and 35cm in depth. the age of the sapling is two years old, and the tender cuttings are good.
3, planting method
Planting trees on the fear of nesting roots, such as the root system is long, can be appropriate pruning, so that the root plant to maintain 20-25CM can be. In the process of filling the soil to the sapling upward gently lift a little, so that the root system to stretch out. Appropriate amount of watering. After the tree hole is filled with soil, step properly and then cover its surface with 5-10CM of loose soil.
4, growth management
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 growth is mainly underground, 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 2-2.5 meters high, and its crown is 1.5-2 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 not the same, generally the tree age 15 years after entering the decline period.
5. Pruning
The top of sea buckthorn is cut when it grows to 2-2.5 meters high. The main points of pruning are: playing horizontal not playing smooth, going to the old to stay new, pruning at the dense place, lack of space to stay strong branches, clearing the bottom of the cut-off pruning.
