Cultivation of potatoes is not easy and painstaking, not to mention the difficult choice of variety. This determining factor is especially important when the climate of the landing area does not meet the needs of the variety. Adretta is a successful hybrid variety that is bred by generations of gardeners. Potatoes have an attractive appearance and excellent taste.
Tubers varieties oval, weighing 130−150 grams. On the surface of the potato there is a small number of eyes. Inside the tubers are yellow, the amount of starch - up to 23%, when boiling - moderate friability. The main characteristic of Adretta is its yield: 40 gross tons of tubers per hectare are harvested on an industrial scale, and up to 12 potatoes from one plant are harvested per garden. In addition, the culture is characterized by resistance to infectious diseases: late blight, cancer and nematode and rarely affected by pests.
Tubers Adretta tasty, useful, contain in its composition B vitamins, carbohydrates and substances that activate the work of the heart and blood vessels. Hybrid has excellent keeping quality. At preservation, a pair of tubers spoils, while others overwinter in cellars without significant damage to taste. Even frozen potatoes do not acquire the unpleasant sweet taste inherent to a large number of species. If a problem occurs, the tubers are sorted, dried and stored further.
Variety Adretta is characterized as unassuming, enduring temperature drops. To achieve maximum yield, you should follow the rules of planting.
For the landing of Adretta acquire seed tubers and germinated before planting. Seed potatoes are scattered in a dry room and, two weeks later, green shoots appear on it. After that, sprinkle the potatoes with water and cover them with plastic wrap for quick germination of the roots. The process begins in April, and in early May, tubers are planted in the ground.
For planting Adretta potatoes choose light and drained loamy and sandy lands, with access of moisture and oxygen to the roots and tubers of the plant. In the sandy soil in tubers more starch accumulates.
HillingHilling of potatoes is a mandatory procedure in growing technology. It is necessary to preserve moisture, the formation of new roots and tubers, saturation of the soil with oxygen. Spud plants twice per season. The first mound is done when the seedlings appear above the soil at 8−10 cm, the second - when the height of the plant is 20 cm.
Spud potatoes in the morning or evening, as the midday sun has a destructive effect on plants.
In hot and dry climates, when there is no systematic watering, the plants do not spud. In friable dry land, tubers are sintered. In this case, loosen the soil between the rows, pull out the weeds and destroy the dry lumps for air exchange and plant growth.
Potato Adretta does not tolerate drought and stagnant water. Therefore, maintain soil moisture, and water the potatoes as needed. On one bush need 3-4 liters of fluid. Water the bushes by sprinkling or in specially shaped furrows.
It is recommended to carry out top dressing in the morning or evening, at the same time it is better to choose windless days with dry weather.
- If the processes grow weak and thin, and the leaves are outwardly painful, make the first part of the feeding. In 10 liters of water dilute 1 tbsp. l urea or ammonium nitrate. A solution of fresh mullein or bird droppings in the ratio of 0.5 liters per 10 liters of liquid is also useful. Under each plant make 500 ml of fertilizer.
- When forming the buds on the leaves, a second dressing is carried out to bring flowering closer. In 10 liters of liquid diluted 3 tbsp. l ash and 1 tbsp. l potassium sulfate. Under each bush pour in 500 ml of fertilizer.
- The third dressing is done at the time of flowering in order to enhance the growth of tubers. To make the desired mixture, dissolve 200 grams of fresh mullein or bird droppings in a bucket of water, and then add 2 tbsp to the resulting solution. l superphosphate. Fertilizer is poured in 500 ml under each plant.
On the skin of tubers dark, rough to the touch spots, later cracking, appear. Potatoes cease to grow, are deformed. The taste noticeably worsens.
The main way to prevent scab - alternation of agrarian species on the same land. Spores of the fungus remain in the soil for 5–7 years, 3–4 seasons live, therefore, if the crop has suffered, wait the period before re-planting potato tubers in the same garden bed. No need to move it with beets and carrots - these plants are subject to the same diseases.
And also correctly selected dressings (fertilizers with sulfur and nitrogen, acidifying the soil), you can free the bed from the pathogenic bacteria for a long time. Natural organic matter, on the contrary, should not be carried away. Fresh cow and horse manure encompass fungal spores. Apply only rotted manure.
Before planting potatoes, they are incubated for 1-2 hours in a 2% solution of an arbitrary fungicide (Bordeaux liquid, XOM, blue vitriol, Kuprozan, Fungazil, Maxim 025, Aqua Flo). If possible, once in 30 days, water the soil under potato bushes with 0.5–1% with a mixture of the same chemicals.
Symptoms of the disease are detected after 2 weeks after punching the first shoots. The leaves begin to turn yellow at the edges, coagulate, then dry and crumble, keeping only the veins. However, the stems turn black at the roots, they disappear. To separate the shoots required the slightest effort. Ripening of tubers in this case can not be expected. If the tubers have managed to start, the disease through the point of unification with the stem is transmitted to them. Such potatoes are no longer eaten. The flesh turns into an unpleasantly translucent translucent porridge with the smell of rot.
The causative agents of the disease overwinter in plant litter, therefore, in the autumn, after harvesting, they release the bed from the foliage. As well as the disease is carried by insects - aphids, Colorado potato beetle, wireworm. Struggling with them. The following preventive measures are taken against the black leg: they follow the rules of crop rotation, carefully select the potatoes before planting, plant only intact tubers, and dry the potatoes in the sun before going to sleep for preservation. By the way, the cellar is treated with a mixture of copper sulphate (0.5 kg per 10 liters of liquid) or hydrated lime (300 grams per 10 liters).
If the infection has affected only sprouting plantsdig up and exterminate the bushes completely. 10 parts of seeded ash and 1 part of copper sulfate are poured into the hole. The bushes, which have already bloomed, are poured over with a bright pink solution of manganese-sour potassium, sprinkled with ash, crushed with chalk. Before flowering, to prevent contamination, the crown is sprinkled with a mixture of copper sulfate (30 grams per bucket of liquid) with the addition of small chips of laundry soap.
Potatoes intended for planting are kept in chemicals prepared according to the guidelines:
Then, by all means, the tubers are dried.
Leaves, pedicels, buds and berries are studded with rapidly growing brown markings with a light green border. The bottom plate is dotted with a thin continuous layer of white-like web. Potatoes on top are covered with depressed gray-brown and brown markings of irregular shape. In the pulp there are traces of the same tone.
For prophylaxis sifted through preserving potatoes, disinfecting the cellar and storage boxes. Selected for planting potatoes put in a sunny place, leaving, protecting from direct sun at a temperature of 18−20 degrees for two weeks. Then reduce the temperature to 8−10 degrees and keep the tubers for about two weeks. 7 days before planting potatoes sprinkle weakly with colloidal sulfur.
Before flowering plants once in 1-2 weeks watered with chemicals:
After flowering, tuber digging twice, sprinkling the crown with HOM, Kuproksat, Ditamin, Azocene, Medex, Polycarbacin three times. The final processing is done no later than 21 days before digging out the tubers.
Traditional methods of dealing with the disease is the sprinkling of tops with a mixture of milk and iodine (3-5 drops per liter) and garlic arrows. Scroll 200 grams of raw materials through a meat grinder, pour a liter of water. After two days, filter and add 10 liters of liquid.
Do not ignore dressing. True mineral supplements will reduce disease infection by half. Carefully make nitrogen-containing drugs. Nitrogen is triggered by the formation of late blight.
Rhizoctoniosis affects plants at any stage of their development. The disease becomes noticeable when it manifests itself in the form of black spots or depressions on the tubers, due to necrosis of the eyes and processes. The fungus calmly overwinter in the soil in the form of mycelium and remains in the soil for up to four years.
The main distinguishing feature is black growths on the roots, resembling dried remains of soil. In this phase, the fungus does not harm the vegetable; damage to the rhizoctoniosis causes emerging shoots - the stems turn black, the plants dry out and die. During the flowering of the culture, scab appears as a net dying off of tuber tissues. This happens already in the dry heat, during the mass budding.
Prevent illness by the following actions:
- careful selection of healthy planting material
- treatment of seed tubers with fungicides,
- crop rotation on the site,
- planting potatoes in a fairly warm soil,
- timely harvesting tops after harvest.
As well as the fight against the problem lies in the careful selection of the landing site - the maximum distance of the potato beds from the places where the nightshade grows. In addition, planting material can be treated with a solution of Baktofit or Quadris. If, however, the affected plants are identified, spray them with Maxim's preparation at least once a week.
Potato harvesting is carried out from mid-July to early September. This is done in dry weather, as wet soil will adhere to the potatoes. After the first decade of September, cleaning is not recommended: the tubers in the ground begin to rot.
Adretta - potatoes that can be stored for a long time, without worrying about the fact that the tubers can deteriorate or rot. Like other varieties, Adretta should be kept indoors with good ventilation. Ideally, the cellar is suitable for these purposes, where the potatoes will be stored, should be well ventilated, dark and dry. The optimum temperature in the room is 2–4 ° C, at lower temperatures, the roots will freeze, and at higher temperatures, they will begin to germinate and become unsuitable for food.
If the goal is set - to get a rich harvest of tasty and burglar potatoes, then there is no better variety than Adretta. Of course, potatoes are subject to some diseases and pest attacks. But these misfortunes are well known and easy to fight. In gratitude, Adretta will delight you with a beautiful view in the field, and excellent taste on your table.
Like other varieties, potato Adretta does not tolerate drought and excessive stagnation of water. Soil moisture should be maintained and potatoes should be watered as needed. 3-4 liters of water are needed per bush. Watering can be done by sprinkling and in specially formed furrows.
Important! A day after watering the soil should be properly loosened with a manual hoe.
Loosening should be done very carefully, trying not to damage the sprouts and not pull the tubers to the surface.
Fertilizer is best in the morning or in the evening in a dry, quiet and windless weather.
- If the shoots grow weak and thin, and the leaves have an unhealthy appearance, you need to make the first portion of fertilizer. In 10 liters of water dilute 1 tablespoon of urea or ammonium nitrate. A solution of fresh mullein or bird droppings in the proportion of 0.5 liters per 10 liters of water is also suitable. Under each bush make 500 g of fertilizer.
- In the formation of buds on the leaves, it is advisable to conduct a second dressing to speed up flowering. In 10 l of water dissolve 3 tablespoons of ash and 1 tablespoon of potassium sulfate. Under each bush should make a half-liter of fertilizer.
- The third dressing is carried out during the flowering period in order to accelerate and increase the growth of tubers. To obtain the necessary mixture, dilute 1 cup of fresh mullein or bird droppings in a bucket of water, and then add 2 tablespoons of superphosphate to the resulting solution. Fertilizer make 0.5 liters under each bush.
