Achievements of domestic breeding science for a long time did not have competition in garden plantations. With the arrival of new items of foreign selection, the situation has changed. And yet many gardeners prefer Russian, proven raspberry varieties who do not need to pass acclimatization. One of these varieties – tourmaline.
History of removal of varieties
Tourmaline varieties are obtained as a result of crossing frost-resistant raspberry varieties from Scotland. Was removed at the Sverdlovsk Experimental Station of Gardening. This one of the oldest scientific institutions of the industry was created in 1935. Leading employees of the enterprise became breeders: l. AND. Chistyakova and I. AND. Bogdanova.
Description of varieties
Tourmaline – Mountain Ripening River, good yield, universal for its intended purpose, with large sour sweet fruits. Forms a bushes with a height of up to 2 m with reprehensive shoots without spikes. Characterized by resistance to major disease diseases. Well transported and stored without changing the color and form of berries.
Timing of ripening
Sort Lateur Vener. The ripening period falls on the third decade of July to the first frosts. Long fruiting occurs because of the stale flowering bush: flowers appear first on the painting escape, then in the middle and then at the bottom. Because of this feature, similar varieties are called half-limit.
The degree of yield is not bad: tourmaline gives from 2 to 3 kg of berries with bush per season. In compliance with the rules of agricultural engineering, one can collect up to 56 kg of fruits. The crop assembly process simplifies the absence of spikes on the branches.
The yield affects the density of planting bushes and the quality of the soil.
Berries and their taste
The fruits of raspberries Tourmaline are large, elastic, elongated conical shape, bright pink and dark raspberry color by the time of full ripening. Color similar to a tint of semi-precious stone tourmaline, and caused the name of the variety. Berries usually weigh 4-5 g, but can reach 7 g. Have a nice sour-sweet taste, perfectly suitable for juices, compotes, desserts and frosts. Can hang on the branches for a long time, easily removed after ripening, busty do not scatter. Very well tolerate transportation, stored without changing the product.
Features of cultivation
Tourmaline – rather demanding of fertility and soil acidity level. It needs to be stimulated by nitrogen feeding in spring and potash during maturation. It grows best in sunny areas with good drainage. High branches need a support device. Purpose alone. Berries and bushes are not burned in the sun, it is not bad to carry dry summer if you get timely watering. Over the season, watering produce about 10 times 10 liters under the bush.
Tourmaline requires mandatory trimming: Moderately thickened raspberry bushes need to cut forward in the fall, removing the sponsors.
Choosing a place and soil preparation
Tourmaline is better to plant on a flat, solar cleaned by weeds. Be sure to withstand the distance 0.5-0.6 m between the bushes and 2-2.5 m between the rows. The soil must contain humus, be loose, not too acidic (from 5.7 to 6.6 pH). Before boarding, the soil must be supported by potash salt or wood ash. In order for moisture from the roots, it is not evaporated quickly, you can put a layer of straw, hay or peat.
Frost resistance and preparation for winter
The winter hardiness of the variety is good, because breeders provided for its cultivation in the conditions of the Middle Urals. The plant is only flexing for the winter so that the bushes are covered with snow. In a minor winter, the raspberry is covered with agriculture or pagan.
If the plant does not bend, then the tops of the bush can be frozen, however, tourmaline is able to quickly recover: powerful fruit branches grow from the bottom of the shoots.
Diseases and pests
Tourmaline is not amazed by gray rot and malinous tick and resistant to fungal infections. The only threat is purple spottedness, manifested in August. From her plant can protect fungicides, as well as timely trimming.
This raspberry grows quite well even in urban areas in the private sector: steady tolerate air bases of the big city.
Breaks tourmaline as root cuttings and green processes or the division of the bush.
In the reproduction of root cuttings in the fall, the roots are separated (15 cm) from healthy bushes, placed in tanks with a soil in a cool place. Roots watered once a month. The container is transferred to the greenhouse in the spring, where the seedlings are stronger until autumn, after which they are already sitting in Malinnik.
When dividing the bush, you can get about 6 new plants. Produce such reproduction in the spring. Green processes 15-20 cm high are also separated in spring and sear in prepared wells.
