Description of the grade raspberry polka
A variety of raspberry polka - a remontant medium-sized variety was bred in 1993 by Polish gardeners from g. Brzezn. Hence the unusual name of the variety: Poland - polka. The result of selection exceeded all expectations.Polka very quickly became popular in Europe and not only. Large-scale distribution of polka in different parts of the world took place after the international agricultural exhibition in 2003 "FruitFocus".
The Polka is fruitful from the end of July to the first frosts (annual shoots).The yield of this variety is extremely higha. According to the results of testing of experimental stations, on average, it is about 4 kg per 1.
Harvest can be harvested twice a year - in addition to harvesting the main crop, last year's shoots yield a harvest in early summer. If you grow raspberries for your own needs,you can leave a part of the shoots for the next year, then, due to the double harvest, you can enjoy raspberries from the beginning of summer to the end of autumn. In industrial scale, in order to avoid damage to the crop (twice a year - a large load on the plant), it is desirable to cut off shoots annually and collect only the main crop. Then the period of ripening of the Polka will be commercially profitable, the bulk of the varieties have already been fertilized, and the polka appears on the trading rows.
Strengths and weaknesses of the variety
One can single out suchthe main advantages of polka:
- ideal berries(it is considered the best dessert sort of Europe);
- high yield(yields of 12 tons per hectare are known)
- longfruiting period(under condition of good feeding, actually harvest twice a year without excessive load on the plant);
- resistance of sprouts and berries(berries do not flow, do not rot and are well preserved on the bushes);
- keeping quality,transportability and dry separation of the yagod (even after freezing berries look fresh);
- good in conservation(suitable for both classic raspberry jam, and for juices, fruit and jelly);
- lack oflargespines(when harvesting you do not have to worry about the integrity of the skin);
- immunity to the most common diseasesthis type (fungal, viral);
- absence of "serious competitors" in the period of fruiting (rightfully considered one of the most cost-effective varieties).
Now about the disadvantages:
- not frost-hardy. Needs shelter and circumcision for the winter under the root;
- does not tolerate high temperatures(above + 35 °). It is necessary to shade berries and bushes, even in the presence of drip irrigation;
- predisposed todiseases of the root system(rot, root cancer, etc.);
- forcing out shootssubstitution;
- needs toabundant replenishment(with a lack of potassium, nitrogen, organic, the formation of shoots falls).
As can be seen from the lists, the shortcomings of the Polish fade to the merits. It can be summed up that polka is good for both commercial cultivation and for oneself.
Characteristics of berries and bushes, yield
The height of the flight of polka can reach, meter. This variety has a very high resistance to shoots.The root system is also quite powerful, one root of an adult plant is able to form many shoots with weakly spiked.
The berries of raspberry polka are beyond praise. The shape of the berry is conical. They are large enough (-3 cm), shiny, have an elongated shape, rich red color, small drupe, strongly pronounced taste and pleasant delicate aroma. The correct balance of sweetness and acid, as well as the density and wateriness will not leave indifferent the connoisseurs of this useful berry.Each brush gives an average of 8 berries weighing 3-5 grams each, that agree, pretty good...
Rules for planting, reproduction and care
Pollen seedlings are planted before or after the end of the growing season. Usually either late autumn or early spring. The correct planting and pruning of planted plants is of fundamental importance. It is advisable to choose a place with good lighting, since in the shade the shoots are stretched too much. The landing can be pit or trench type, occurs in a ribbon way. Beforehand it is necessary to clear the plantation for planting from weeds.Plant seedlings in such a way that the distance between plants is in the row / 1m, row spacing / 2 m. For a year the rows are intertwined, the distance between the seedlings will be about 35 cm. Escape in the bush it is desirable to leave no more than 7, otherwise the plant will need very abundant food. Ideally, if the soil is moderately drained, podzolic or slightly acidic (pH not higher than 7). In a trench or pit depth of 40/45 cm, a suitable nutrient mix is laid (traditionally potash, phosphoric and dobriva plus compost or manure).
About polka food:the growth of seedlings is quite active,in the first bait the plant needs in Aprile. Here, organic nitrogen and potassium fertilizers are added to organic potassium and phosphorus fertilizers. It is possible to use complex top dressings.The second feeding is carried out in the middle of summer and the third in September. Do not forget about regular watering. By the way, plants more actively absorb top dressing, if it occurs after watering, then it is desirable to loosen the soil. Do not overdo it with fertilizers, an overdose is as harmful as can plant a plant.
Although the variety is medium-sized, shoots need support. Especially in conditions of insufficient illumination, the tips of the tree saplings bend under the weight of the berries in the brush. As trellises, it is best to use V- or T-like supports made of galvanized wire, at least 4mm thick.The distance between the rows of wire is 50-70 cm. The tension of the wire is optimally carried out with the aid of special tensioning devices. After the shoots are bred and laid on opposite sides, fixing on the wire pieces of strong rope. From time to time you need to thin the raspberry, as the polka gives a lot of growth.
For the winter, shoots are advised to cut to zero(except for cases where it is necessary to "stretch" the crop for personal needs) and to hide (with the exception of southern regions). Mulch the polka with straw, turkey, top peat. Top covered with agrofiber. It is strictly forbidden to water wintering raspberries.
Reproduction of polka occurs due to the dissection of root offspring.In the second half of summer offspring undermine, separated from the mother's root with a clod of earth and planted in a permanent place in raspberries. The optimal weather for such a procedure is rainy and cloudy, on a sunny day, the seedlings are pritenit. Pour 1 liter into the prepared pit. water and put there offspring with leaves. Approximately in half a month the seedlings start in growth and reach the standard size for wintering..
Diseases and pests
It was noted above thatPolka is not susceptible to common "crimson" diseases, such as spider mite and gray mold. Worms and other small pests are unrealistic to meet, as the bushes begin to blossom and bear fruit after the bulk of the repairing varieties. And pests are known to prefer early fruits. But is everything so cloudless?
To combat it, physiologically acidic phosphorus-potassium fertilizers and gypsum contribute to the soil.
Also,With a lack of potassium or high soil acidity, the bush can react with redness on the foliage. The same trend is observed in malnutrition. Usually, to improve the raspberries in this case, just before watering, fertilize the plants with wood ash..
