The Latest Blackcurrant Cultivation Techniques and Methods Tutorial
The scientific name of blackcurrant is blackcurrant, also known as black currant, black bean fruit, purple plum. It is a small shrub, and its fruit is a small black berry when ripe. It can be eaten and can also be processed into juice and jam. Its nutritional value is extremely high, rich in vitamin C, anthocyanins, and a variety of trace elements beneficial to the human body, and it can also help prevent gout, anemia, edema, arthritis, rheumatism, and other symptoms. So do you know how to cultivate it? Let's take a look together.
1. Site selection and land preparation
Blackcurrant can grow in a fixed location for more than twenty years, so a good planting site should be chosen according to its growth characteristics so that it grows and develops well and can continuously produce berries. A area with sufficient sunlight, flat terrain, deep soil, close to a water source, and convenient drainage and irrigation should be chosen. If it is a mountainous area, a site with a certain slope can be chosen, which can avoid closing off, and the slope must not exceed 10 degrees. After clearing the weeds and residual plants from the planting site, apply base fertilizer in combination with plowing, then harrow fine and level, and wait for planting.
2. Propagation methods
When planting blackcurrant, two methods, cutting and layering, can be used for propagation. After autumn, cut robust-growing branches from the mother plant, cut them into 20-25cm cuttings, and store them in a cool place. When the temperature rises in spring, the cuttings can be trimmed to a length of 10-15cm for cutting propagation. Generally, they can take root after about half a month. As long as management is proper, they can become seedlings and be planted in autumn. For layering propagation, in spring, scratch or peel the branches produced last year and press them around the plant, burying them about 5cm deep. After the root system grows, earth up to expand the rooting range. In autumn, they can be separated from the mother plant and planted.
3. Planting
The planting time can be chosen in autumn or spring. In autumn, it is from October to before freezing; in spring, it is around April. When planting, the planting density should be reasonably controlled according to the characteristics of the variety and the planting method. Generally, for larger plants that need to be buried in cold conditions, a row spacing of 2×1.5 m is suitable, while for smaller plants that do not need to be buried in cold conditions, a row spacing of 2×1.25 m is suitable. The row spacing can also be increased or decreased according to actual conditions. The planting depth is generally 6-8cm, adjusted appropriately according to the height of the terrain. When planting, first cut the seedling, leaving about 8-12cm of the stem base, and ensure there are 3-4 buds to help form side buds. Then apply base fertilizer in the planting hole, backfill half of it, then straighten the cut seedling and plant it well. When covering with soil, lift the seedling gently several times so that its root system is closely connected with the soil, then cover with soil and press firmly, and water thoroughly.
4. Field management
Field management after planting is related to yield, so it is especially important. It is mainly done in terms of fertilizer, soil, and water. For fertilization, it is best to use decomposed farmyard manure combined with nitrogen, phosphorus, and potassium compound fertilizer to achieve physiological balance among the elements. Water is indispensable for crop growth. In order to meet the needs of blackcurrant growth, its water requirements must be satisfied, and the soil should be kept moist at all times. Drainage should be done in time during the rainy season. In addition to water and fertilizer management, the orchard soil should also be kept loose to meet the plant's requirements for soil. Cultivate and weed once regularly to promote the growth of the plant's root system and accelerate the normal growth and fruiting of the aboveground parts of the plant.
