Seabuckthorn breeding and management

Seabuckthorn, also known as vinegar willow, sour spine, black thorn, is a genus of sea buckthorn belonging to the genus Kezi, and is a deciduous shrub with symbiotic nitrogen fixation. Plants up to 3 to 10 meters in size, with stout thorns, young branches dense brown scales. Leaves alternate or nearly opposite, 2 cm to 6 cm long, 0.4 cm to 1.2 cm wide, blunt at both ends, the back is densely talked about white scales. Flowers pale yellow, flowers small, dioecious, flowering from March to April. The fruit is nearly spherical, orange or red, and the fruit matures from September to October. Seabuckthorn is widely distributed in Eurasia. China's northwest, north, northeast, and southwest regions all have large areas of cultivation.
1. Seabuckthorn can be seeded, rooted, hardwood cuttings, tender cuttings and other methods.
Seed nursery: soaking in warm water from 40°C to 60°C for 24 to 28 hours. Put 2% potassium permanganate in warm water for seed disinfection, remove and mix in river sand and soak it, and wait for 1/3 of the seeds. Split mouth, you can sow. About 10 pounds per acre sowing rate, using drills, spacing 25 cm to 30 cm, 2 cm seed cover. Before the planting of the seedlings, sufficient base fertilizer should be applied to fill the bottom water and the ground should be leveled. After sowing, the bed soil should be kept moist.
Root Propagation: In the year of planting, select roots that are well developed from 1 to 2 years old. Cut roots 10 to 20 cm away from the trunk and mark them as female or male. After survival, it will be transplanted into the planting site.
Hardwood cuttings: In the early spring, choose healthy, disease-free and completely lignified cuttings of the year. Cuttings are 15 cm to 20 cm in length, 0.5 cm to 1 cm in thickness, and 3 to 4 full shoots are maintained. Press after cutting. 50 to 100 bundles, soaked for 24 to 48 hours, only 3 cm to 4 cm in the root. In order to promote rooting, ABTl rooting powder can be used 50ppm to 100ppm, soak 10 to 24 hours, immediately after dipping cutting, bed temperature maintained at 25 °C to 28 °C, spray permeable, then keep bed soil moist, seedling height 15 cm to 20 In centimeters, the seedlings are cultivated for 7 days to 10 days and transplanted into the nursery or cultivated land.
Twig Cuttings: From June to July, select the mother tree that grows and has good results. Bars 12 cm to 15 cm long, 0.5 cm to 1 cm thick, with only the parietal lobe, other leaves removed, immersed in ABT rooting powder, immersed in a plastic greenhouse or greenhouse, shading management. When the seedling height is 15 to 20 centimeters, the seedlings are transplanted into the nursery to be planted and managed in the fall or next spring after 7 to 10 days of hardening.
2. The cultivation and management of seabuckthorn planting density depends on the tree vigor of the variety, which is convenient for mechanized tending. In order to pollinate, one line of pure female plants should be taken and one line of female and male plants mixed and alternately planted. Colonization should be well-grounded, pits should be well-drained, base fertilizer should be applied to where conditions permit, and rooted water should be filled immediately after planting, and the cracks should be sealed with soil after irrigation.
In the first 4 years, cultivating and weeding should be carried out every year. Where conditions permit, some urea should be applied during the rainy season. Every year, sparse shearing is performed to remove excess dried branches and branches and diseases and to improve the illumination of the trees. Seabuckthorn has less pests and diseases, and pesticides should be promptly sprayed when pests are found. By strengthening management, the use value of seabuckthorn can be better improved.
