A Detailed Guide to Sea Buckthorn Planting Methods and Key Technical Points
Sea buckthorn fruit contains abundant nutrients and bioactive substances, and can be widely used in many fields of the national economy such as food, medicine, light industry, aerospace, and agriculture, animal husbandry and fisheries. Below is a carefully compiled guide to sea buckthorn planting methods; let's take a look.
Sea Buckthorn Planting Methods
Planting methods:
Sowing, cuttings, layering and tiller propagation, with extensive management. Sea buckthorn that is growing can be cut back flat to encourage new branches and achieve rejuvenation. At present, the sea buckthorn series products of Wenchuan Dayu Farm have become a leader among modern health foods.
Planting time:
Sea buckthorn can be planted in both spring and autumn. Generally, spring planting is from April to early May, and autumn planting is from mid-to-late October to early November, after the trees shed their leaves and before the soil freezes. Seedlings planted in autumn take root and sprout early the following spring; by the time the late-spring drought arrives, the trees have already returned to normal, enhancing drought resistance, so autumn planting gives better results than spring planting.
Planting density:
220 plants per mu (666 sq m). Spacing between plants and rows is 1.5 m X 2 m. Sea buckthorn is dioecious, with a male-to-female ratio of 8:1. The size of the planting hole depends on the size of the seedling, generally 35 cm in diameter and 35 cm deep. Two-year-old softwood cutting seedlings are best.
Planting methods:
When planting trees, the main concern is root balling; if the root system is too long, it can be trimmed appropriately so that the root length stays at 20-25CM. During the process of filling in soil, lift the seedling gently upward so that the root system spreads out. Water appropriately. After the planting hole is filled with soil, tread it down appropriately, then cover the surface with 5-10CM of loose soil.
Growth management:
The growth of sea buckthorn is divided into four stages: seedling stage, fruiting stage, full fruiting stage, and decline stage. Within two years after planting, underground growth predominates, while aboveground growth is slow. Growth is vigorous at 3-4 years, and it begins to flower and bear fruit. An adult sea buckthorn tree is 2-2.5 m tall, with a crown width of 1.5-2 m. It enters the full fruiting stage in the fifth year. Due to differences in soil conditions and management, the time of entering the decline stage also varies; generally, trees enter the decline stage after 15 years of age.
Growth pruning:
When sea buckthorn grows to 2-2.5 m tall, cut the top. The key points of pruning are: cut horizontal branches but not upright ones, remove old branches but keep new ones, prune where dense, keep vigorous branches in gaps, prune the inner canopy and lower part well, and the crown will be full and yields high.
Precautions:
Sea buckthorn is a medicinal food containing multiple vitamins, multiple trace elements, multiple amino acids and other bioactive substances. For a bumper harvest of sea buckthorn, attention should be paid to the following points:
Build soil fertility and strengthen tree vigor
First, increase the supply of various essential elements to the tree, especially in established orchards, and increase the application of nitrogen, phosphorus and potassium fertilizers. Apply more organic fertilizer, pay attention to irrigation and drainage, maintain moderate soil moisture, and spray New High Lipid Membrane at the right time to retain fertilizer and water, effectively promoting tree vigor and enhancing disease resistance.
Shape and prune the tree form, strengthen flowers and promote fruit set
Promptly clean up and prune diseased branches and dead branches, scrape off diseased bark, and promptly apply wound-healing antiseptic membrane to the cut and pruning wounds to promote wound healing and prevent invasion and infection by pathogens. At the bud stage, young fruit stage, and fruit expansion stage respectively, spray Zhuangguodiling to thicken the fruit stalk, increase nutrient transport, prevent flower drop, improve pollination capacity, increase fruit set rate, accelerate expansion speed, and ensure high-quality, high-yield fruit.
Promote flower bud differentiation and balance fruit set rate
Alternate bearing of the tree causes an imbalance in the tree's load, which affects both balanced returns and orchard tree health. During the flower bud differentiation period each year, brush Cuhuawang No. 2 around the trunk once, which can greatly promote flower bud differentiation, increase flowering and fruit set rates, inhibit excessive shoot growth, and thoroughly balance alternate bearing.
