This berry bush is widespread in most regions of our country thanks to its tasty and healthy fruits. Blackcurrant is often grownup with none issue in sandy loamy soil, that retains wet well. It doesn't tolerate serious clay, however, it will manufacture sensible yields on all sorts of wet soil, as long as it contains enough organic matter.
It ought to be noted that blackcurrant needs heaps of chemical element once growing, prefers soil with acidity - the pH varies from vi.7 to 7, can't tolerate acidic soil. Additionally, it produces a tiny low yield if grownup in areas receptive to the winds. This plant has the power to face up to temperatures right down to -20°C. However, flowers area unit broken if the temperature drops to -1°C. Fruits don't seem to be tied with such harm.
Blackcurrant within the Kuban begins vegetation terribly early. Kidneys get up in early March. Anthesis takes place within the 1st and second decade of April, once the air temperature exceeds 10°C and lasts 7-12 days. It depends on the peculiarities of the variability of current, climate. Flowering is often shifted to earlier or later dates by 8-15 days.
Good preservation of flowers and their fecundation is one in every one of the vital conditions for getting the harvest. Black currant flowers of standard form area unit lined with 5 petals, five - with stamens and pistils. Fertilization happens once spore from explosive spore on the pistil's tip is connected with the spore. Yield depends on traditional fecundation. Fairly often currants bloom extravagantly, however, there's no harvest. Ovaries fall 2-3 weeks once flowering, that is, fertilization doesn't occur. What's the reason?
Self-propelled fruit is well pollinated with its own spore or spore of its own varieties. Though the variability is self-propelled, cross-pollination is additionally attainable. Cross-pollination on self-propelled bushes produces massive berries and better yields.
Self-berry varieties don't seem to be pollinated with their spore. They're pollinated solely with a spore from different pollinators. They have bound conditions: the presence of a variety of planted styles of pollinators, the involvement of bees and different insect pollinators. For this purpose throughout flowering, it's necessary to spray bushes with honey resolution (100 g of honey per one l of water). The aroma of honey attracts bees, bumblebees and different insects that employment even in windy weather. It promotes higher cross-pollination of flowers, fastening of berries.
For finest fecundation, it's conjointly effective to spray flowering currant bushes with atomic number 25 resolution of one.5 g + chemical element acid one.5 g per ten liters of water. It's vital to own self-berry varieties on garden plots, that area unit ready to fecundate, tie berries in adverse climate throughout flowering. All styles of blackcurrant ripen in a Gregorian calendar month. Solely terribly late varieties generally ripen within the 1st decade of Gregorian calendar month. Climate for growth, ripening of berries in May-June area unit quite favorable, that is, the yield depends on gardeners, protecting measures on their sites.
Most styles of black currant area unit extremely winter-resistant, face up to forty degrees frost, even lower, buds don't seem to be broken. However within the amount of its anthesis within the Kuban area unit usually unfavorable weather conditions: rainy, windy weather, that complicates the years of insect pollinators, low positive air temperatures throughout the day, come spring frosts in the dead of night, that causes harm to flowers, young ovaries in unstable varieties.
To increase the steadiness of currants to such unfavorable conditions it's necessary to arrange bushes from time of year. Phosphorus-potassium fertilizers and ash ought to be applied for dig or loosening the soil. If the time of year is dry, watering ought to be disbursed. Plant many varieties in your own soil. Place their pollinators next to low-fertilized varieties. Rather than varieties that area unit unstable to come spring frosts, for instance, Belarusian sweet to plant extremely stable, withstanding a visit temperature throughout flowering to -5 ° C. Such varieties are developed by Russian breeders, there area unit heaps of them in the Kuban. Here area unit a number of them: Altaianka, Grape, Dobrynaya, Izyumnaya, Lyubava, Nara, Gift to Kuminov, Sevchanka, Selechenskaya-2, et al.
