Cranberry large-berry
Background: in Russia, most of the cranberries continue to be harvested in the marshes, although in the US and Europe it has been introduced to culture for more than 150 years. Cultivated varieties come from North America, it is not as frost-resistant, but has larger berries and yields higher yields.
Requirements: cranberry is hygrophilous( requires a high groundwater table - 30-45 cm for marsh cranberries and 43-55 cm for large-fruited), unpretentious, frost-resistant. It grows well on sandy and loamy soils, poor and with acid reaction.
Ingredients: berries contain sugars( mainly glucose and fructose), organic acids, zitamins, pectins, tannins, phytoncides, vitamin C and P-active substances in large quantities, mineral compounds of calcium, potassium, iron, copper, silver and others.elements( total 25).Thanks to the presence of benzoic acid, berries in fresh form can be stored for a long time.
Planting: the area for cranberries should be located in a well-lit area near the water source. On heavy soils, good conditions for growing plants can be created by applying to the surface 20-25 cm of peat moss, followed by sand mulching with a layer of 3-5 cm. On poor mineral soils, organic fertilizers - peat, humus, forest litter( 1-3 buckets per 1 m2) and mineral, mostly superphosphate( 20-30 g / m2).Cranberries are propagated by cuttings length of 10-15 cm, harvested from shoots of growth of the past or the last two years. On sale are both cuttings, and 1-2-year-old seedlings, grown from them. Plant cranberries in spring( cuttings and seedlings) or in the fall( saplings).For planting it is necessary to prepare a special ridge - remove the soil by 25-30 cm, carefully remove the rhizome of weeds and fill the pit with a mixture of peat with large river sand( 5: 1), adding 1-2 buckets of leaf or coniferous humus and 10 grams for each 1 m2double superphosphate. All mix thoroughly. If the subsoil is light, sandy, then the bottom of the pit is lined with thick polyethylene film, the sides are necessarily strengthened with boards or slate, burying them in the ground. For a day or a few hours before planting( usually in early May) the soil is strongly moistened, then mark the plot according to the scheme of 10x15 or 10x10 cm. The closer the planting, the faster the shoots of the plants will cover the soil surface, the easier it will be to fight the weeds and rather the fruiting. It is necessary to know that cuttings can be stored for some time( 5-10 days) in cold water with full or partial immersion, in wet sphagnum moss, cloth or plastic bags on the bottom shelves of the refrigerator. This allows you to reduce the tension in the timing of the preparatory work and extend the landing period if necessary. Cuttings are planted with a T-shaped peg, deepening so that there are peaks 2-3 cm high on the surface. The planting is watered so that the soil is compacted and there are no voids, and later constantly maintain high humidity.
Within 3-4 weeks the cuttings become rooted and the shoots begin to form. To stimulate their growth, complex complex fertilizers containing nitrogen, phosphorus, potassium, magnesium and trace elements - boron, copper, manganese and zinc
