The variety with the interesting name Izobilnaya appeared thanks to the crossing of Stolichnaya raspberries and Elizabeth Kip. The new variety is also known as Izobilnaya Kazakova. Dessert designation indicates the sweetness and high palatability of the berries.
Description of the variety
A feature of this variety is the absence of thorns. The bushes are strong, semi-spreading and compressed. They reach a height of 2 meters. Young shoots are elastic, of medium thickness. The next year, they turn red, become large and gain up to 3 centimeters in diameter. Small leaves have a smooth structure, the color is dark green, with a gray tint. The green mass is not very dense due to the fact that the leaves are located far from each other.
Ripening terms
In one growing season, a remontant variety can be harvested from 5 to 6 crops. Ripening time is average. Shrubs begin to bear fruit from the beginning of July (3-8 days) and until the end of the month.
Yield
Productivity of raspberries Abundant high, as indicated by the volume of berries harvested. From one plant get from 4 to 4.5 kg of fruit or 20 tons per hectare for commercial cultivation. It is worth noting the transportability of the berries, which allows them to be transported over a long distance without losing quality.
Berries and their taste
Fruit weight varies from 4 to 10 grams, sometimes there are specimens that gain more than 14-15 grams. The shape is correct conical. The color is bright red. Gardeners mark sizes as large or very large. The surface is glossy, with a slight sheen.
Raspberries are very sweet, with juicy and firm pulp. Despite the rich sweetness, a delicate sourness is noticeable in the berries. The aroma is bright, raspberry. The fruits are often eaten fresh due to their high gastronomic qualities and mouth-watering smell. When harvesting, raspberries do not flow and retain their shape.
Note: the taste of the berries directly depends on the growing conditions and climatic characteristics. If you break the rules of agricultural technology, the berries can become sour and watery.
Growing features
The frost-resistant variety can be cultivated in cold regions. The fruit crop loves the sun and does not tolerate strong winds. In the south of the country, shrubs should be planted in the fall, after the heat has subsided. Warm and damp weather will help the seedlings adapt to new conditions. In the north, it is better to plant in the spring, before the buds open. In these regions, cold autumn, and young plants do not have time to take root.
When choosing a ready-made planting material, it is recommended to buy shrubs with a whole earthy clod or in pots. Otherwise, the seedlings should be carefully examined for damage and infections.The roots should be flexible and the buds on the cuttings should be slightly swollen.
During planting, open roots are gently straightened and covered with earth. The soil is tamped and each plant is watered with 10 liters of water. A layer of mulch from dry plant material is formed on top of the ground. It is important that the root collar stays flush with the soil.
Site selection and soil preparation
The site for the raspberry tree is chosen depending on the region. In the middle zone and in the northeastern regions of the country, horticultural crops are planted on the south side so that the berries receive a sufficient amount of heat and light. The southern regions are famous for sultry weather conditions. Plants begin to dry out under the scorching sun. An area with partial shade is best suited.
Special attention is paid to the composition of the soil. Abundant prefers fertile and non-acidic soil (sandy loam or loamy). Landings are made on a hill or plain so that excess water does not stagnate.
The area for the cultivation of raspberries is prepared in advance. The earth is dug up so that the roots receive a sufficient amount of oxygen. If the acidity level exceeds the permitted level, it can be corrected with lime. The depleted soil is necessarily fed with organic compounds, especially if other fruit crops grew on the selected area earlier.
A small dose of fertilizer is placed in each hole or groove before planting. The following substances are used: phosphorus fertilizers, humus, ash, chicken droppings.
Pruning
Be sure to remove dry and damaged shoots. The work is carried out in spring or autumn, depending on the time of planting. Branches that have managed to bear fruit are also removed. To activate the growth of lateral shoots, pinch the top. When the shrubs reach a height of 2 meters, the shoots are cut to the same level with the trellis.
Watering and feeding
In areas with hot climates, trench or drip irrigation should be organized. Berry culture is very fond of moisture. In the northern regions, irrigation is carried out in the summer. The roots of the plant are located at a depth of 30-40 centimeters, so the water must reach this mark.
Raspberry is fed 3 times per season. If the site was fertilized before planting seedlings, you can do without further fertilizing for 3-4 years. With the onset of autumn, manure is scattered between the rows. For the growth of green mass, nitrogen fertilizers are used, and for the ovary of juicy berries - mineral fertilizing.
Frost resistance and preparation for winter
The Izobilnaya variety is not afraid of frosts down to –30 ° С. Shrubs will survive the winter under a snow cover of at least 1-1.5 meters. Otherwise, without additional protection, raspberries will freeze. To protect the plantation, raspberries are removed from the supports, pressed to the ground and insulated with a covering material, coniferous spruce branches or geotextiles.
Diseases and pests
Raspberries are rarely attacked by common diseases and harmful insects.
If the shrubs are not properly cared for, the plantation can be attacked by some infections.
Waterlogging of the soil can provoke a fungal disease called anthracnose. Symptoms are blue or purple spots on leaves with a burgundy border. For protection, the plants are treated with Bordeaux liquid (3%).
The presence of growths on the roots indicates root cancer. To prevent the onset and development of the disease, the root system is treated with copper sulfate. Then it is dipped in a clay mash.
Damp and cool weather often causes powdery mildew. To combat it, use ready-made means: "Profit Gold", "Fitosporin" and other drugs. A light bloom indicates the presence of infection.
The well-known drug "Rubigan" will help to cope with the purple spot. This fungus often attacks berry plantations.
Unfortunately, raspberries, like other plants, do not bypass various diseases and pests. Only armed with the knowledge and the necessary means for this, you can cope with such troubles. To help the plant, it is very important to be able to recognize the disease in time and begin timely treatment.
Reproduction
With the help of semi-lignified shoots, you can get new planting material on your own.
Cuttings are prepared in the fall. Selected shoots are cut by 12 centimeters. After the branches are treated with a preparation to stimulate growth. The cuttings are transferred to a greenhouse without heating and sprinkled with peat for rooting.
With the onset of spring, the planting material is transferred to pots or greenhouses.
Once the plants have reached a height of 30 centimeters, they should be transferred to a separate container with a volume of 1.5 to 2 liters.
Young seedlings are planted in open ground when the warm weather has settled.
