Blueberry Goldtraube 71 was bred by the German breeder G. Geermann. The variety is obtained by crossing the American varietal tall blueberry with the undersized narrow-leaved V. Lamarkii. Blueberry Goldtraube 71 is not included in the Russian State Register.
Description of blueberry variety Goldtraube 71
Blueberry Goldtraube 71 is a deciduous fruit shrub of the Heather family. In its adult form, it forms a sprawling bush, a well-developed root system. Subject to agricultural technology, it reaches a height of 2 m.
From the photo of the Goldtraube 71 blueberry, you can see that the leaves of the bush are bright green, oval in shape. In autumn, the foliage changes color to red. The shrub blooms from mid-summer with bell-shaped flowers, white or pale pink.
The description of the Goldtraube 71 blueberry indicates that the variety is suitable for growing in container culture. Has increased frost resistance, belongs to the 4th zone of winter hardiness. It can withstand temperatures up to -32 ° C without shelter.
Features of fruiting
Blueberry Goldtraube 71 is a self-pollinated variety. The bush can be planted singly. But with the possibility of cross-pollination with blueberries of other varieties, the yield increases.
Berries of the variety are light blue, round, 16 cm in diameter, collected in dense clusters. The mass of one berry is 1.9 g. The yield of the variety is average - 2.5-3 kg from one adult bush. In fruiting, the culture enters at the beginning of August. The taste of the berries is sweet and sour.
Berries of the Goldtraube 71 variety are consumed fresh, used as a filling for pies and prepared in the form of jams and preserves.
Advantages and disadvantages
Blueberry bush Goldtraube 71 looks decorative throughout the warm season. The advantages of the variety also lie in its high adaptation to cold climates. The Goldtraube 71 variety is unpretentious to grow and is suitable for beginner gardeners.
The disadvantages of the Goldtraube 71 variety include its average yield and the presence of sourness in the taste of berries.
Breeding features
To preserve the characteristics of the garden blueberry variety Goldtraube 71, propagation of the shrub is possible only in a vegetative way. For reproduction, methods of cuttings or layering are used.
For cuttings, material is collected at the end of June from coppice shoots, which root better than shoots from the fruiting zone. Lignified cuttings are also suitable for propagation. The retracted shoots, which are pressed to the soil to obtain planting material, take root for a long time, within 2-3 years.
Planting and leaving
Blueberries of the Goldtraube 71 variety are demanding on the acidity of the soil. The culture is grown only in an acidic substrate. The soil pH should be between 4.5 and 5.5. Unsuitable soil at the planting site is completely replaced with acidic, using a mixture of coniferous litter and high-moor red peat.
Recommended timing
Blueberry seedlings are kept in containers before transplanting. In the container, the seedling can be left for a long time before planting in the main place.
Young plants with a closed root system are transplanted throughout the warm season.Spring planting is preferable, with it the plant manages to root well during the summer and tolerates the first winter better.
Site selection and soil preparation
The place for planting blueberries of the Goldtraube 71 variety is chosen permanent, because an adult bush does not tolerate transplanting well. Plots where other crops have not previously grown and the land has not been exploited are best suited. The place for the shrub is sunny, protected from strong winds. The depth of the groundwater should not exceed half a meter.
When planting in groups, shrubs are planted in rows from north to south. The distance between bushes in a row is 1.2 m, and between rows - 1.5 m. Blueberry Goldtraube 71 does not coexist well with other representatives of heather, for example, cranberries.
Landing algorithm
The root system of blueberries is fibrous, does not go far into the soil. A planting hole for one bush is dug 1 m in size on all sides and 0.5 m in depth. For planting, peat substrate is mixed with mineral fertilizer in an amount of 20-30 g per 1 sq. m. A drainage layer of about 5 cm from rotted pine sawdust or bark is poured onto the bottom.
In order for the blueberry bush to take root well in the future, when planting, it is especially important to break the earthen ball and release the roots, which, from a long stay in a cramped container, germinated inside the coma. For this, the container with the seedling is released for 15 minutes. in water.
After soaking, the root system is freed from the soil and the roots are carefully straightened so that they are evenly spaced in different directions.
Planting a blueberry seedling:
- The plant is planted vertically, the roots are straightened, buried 5-7 cm from the general soil level. The soil is lightly pressed.
- Plantings are watered abundantly.
- The soil is mulched to a height of 5-8 cm with coniferous litter.
To prevent the mulch from eroding from irrigation, a curb tape is installed along the diameter of the planting pit.
Growing and care
When growing blueberries, it is necessary to monitor the moisture and acidity of the soil, to keep the planting site clean of weeds. Otherwise, according to reviews of Goldtraub 71 blueberries, the variety is not difficult to care for. The annual growth of branches is 50 cm, green foliage and an increase in yield indicate that the shrub is grown correctly.
Watering schedule
Maintaining soil moisture is necessary for the life of mycorrhiza. Drying out of the soil leads to the death of the plant.
For the entire period until the seedling takes root, the soil is kept moderately moist. For this, it is best to use drip irrigation. An adult bush is watered several times a week, using 10-15 liters of water per watering. In dry weather, spraying with water over the crown is added.
Abundant watering is especially important from the middle of summer, during the periods of fruiting and the setting of flower buds for the next harvest. Despite the demands of the culture on regular watering, moisture stagnation at the roots should not be allowed.
Feeding schedule
For feeding blueberries, only mineral fertilizers are used, which begin to be applied from the second year of cultivation. The first feeding is carried out during the period of swelling of the kidneys, the second - after 1.5 months. Manure, bird droppings, humus and ash are not used to fertilize shrubs.
If the required pH level is violated, the shrub loses its yield, the leaves turn pale green. To maintain the acidity of the soil in the spring, a handful of colloidal sulfur is introduced under the bush. Periodically, citric or oxalic acid is added to the water for irrigation in a ratio of 1 tsp. for 3 liters of water.
Pruning
For blueberry bushes of the Goldtraube 71 variety, only sanitary pruning is carried out. During the spring inspection, very thin and broken shoots are cut off.After 5 years of cultivation, dry, non-fruiting branches, as well as small bushy growths, are removed from the bush.
Preparing for winter
Only young plants are prepared for winter, covering them with spruce branches. Mature bushes tolerate winter well under the snow. In areas with little snow, the bushes can be covered with spunbond.
Pests and diseases
With proper agricultural technology, blueberries show good resistance to diseases and pest attacks. But with weak immunity and disturbances in care, the plant can be exposed to fungal infections.
Common shrub pests are May beetle larvae, leaf rollers and aphids. Birds eat delicious berries.
Conclusion
Blueberry Goldtraube 71 is a fruit shrub, cultivated form of forest blueberry. Subject to the peculiarities of planting and cultivation, the shrub yields a good harvest of vitamin berries at the end of summer, when many trees and shrubs have already finished bearing fruit.
