Features of planting and growing
Variety Nandina is distinguished by unpretentious care... To grow a crop, standard agrotechnical techniques are used: watering as needed, hilling bushes, weeding, loosening the topsoil, fertilizing with minerals.
Preparing tubers for planting
For an early harvest and three harvestspreselected tubers germinate... Seed material is taken out of the cellar into the sunlight, re-sorted, rotten specimens are discarded, washed with running water, dried and soaked in a disinfecting solution. To do this, use copper sulfate, potassium permanganate, "Prestige", "Fitosporin-M". Then the tubers are put in boxes with holes and wait for the emergence of seedlings. The optimum room temperature is + 14… + 16 ° С.
Before planting in the ground, the seeds are treated with growth stimulants "Epin-Extra", "Zircon", "Albit", "Immunocytofit" and re-sorted.
Soil preparation
Nandina grows best on gray light forest soils, peat bogs, sandy loam... Black soil and heavy soil for this variety is not the best option.
In autumn, digging, harrowing and loosening of the earth are carried out. To increase fertility, the site is fertilized with manure at the rate of 5 kg per sq. m, sow flax, lupine, rye, oats, wheat. After 30 days, the mowing of these green manures is embedded in the soil to enrich the land with nitrogen and prevent the development of pathogenic microflora.
Timing, scheme and landing rules
Ideal ground temperature for planting potatoes + 8 ... + 10 ° С. The lunar calendar is used to calculate the time.:
- in the North Caucasus region, potatoes are planted in April;
- in the Central - in early May;
- in Volgo-Vyatsky - from 10 to 15 May.
Landing scheme:
- depth - 8-12 cm;
- the gap between the holes is 30-35 cm;
- row spacing - 70-90 cm.
In each well put 200 g of wood ash and 25 g of nitrophoska.
Care
Care rules:
- Watering. With normal rainfall, Nandina does not need regular watering. However, in drought, the bushes are watered every 10 days. With hand irrigation, water after sunset to prevent sunburn on the leaves. When using a drip irrigation system, the soil is moistened at any time.
- Loosening of the soil. This procedure prevents the formation of a dense earth crust, provides free access of oxygen to the root system and tubers.
- Weeding. Weed removal is carried out as the plants grow, preventing rooting.
- Hilling is carried out twice: after the sprouts reach 10-15 cm in height and during the flowering period. This helps to strengthen the rhizome, protects against night frosts, and stimulates tuberization.
- Top dressing... The variety does not require additional organic fertilization during growth. The manure and ash introduced in the fall during planting is quite enough for the harmonious growth of tops and tubers. An excess of nitrogen provokes the growth of green mass and shrinkage of tubers. If the tops turn yellow and dry, the bushes are additionally sprayed with a mineral solution a month before harvest: 35 g of ammonium nitrate, 20 g of superphosphate per 10 liters of water.
- Mulching. This is not a mandatory procedure, however, covering the beds with straw or hay will retain moisture in the soil and stop the growth of weeds.
Diseases and pests
According to the originator's data, the Nandina variety is susceptible to late blight of tops and tubers.... Disease Causes Fungus late blight - a mycelial lower organism parasitizing on plant tissues.
Signs of the disease:
- brown spots on the lower leaves;
- white bloom on the back of the leaf;
- longitudinal brown stripes on stems;
- depressed brown spots with a gray tint on tubers;
- rusty necrotic lesions of the pulp;
- dry or wet rot on tubers.
Ways to fight:
- 200 g of dried tinder fungus per 2 liters of boiling water. Wrap the container with a warm cloth, leave to cool completely, then strain. Process the bushes every 10 days.
- 500 g of wood ash, 100 g of tar soap shavings per 10 liters of water. Handle the planting at any time.
- Systemic chemicals: "Quadris", "Ridomil Gold", "Thanos", "Infinito", "Ordan", "Acrobat MC". Process the plants every 10-12 days.
- Contact chemicals: Antracol, Azofos, Ditan, Zummer. Process the bushes every 7–8 days.
- Copper-containing substances: "Oxyhom", "HOM", "Polychom", "Bordeaux mixture".For 40 g of the substance, take 10 liters of water. Consumption per 100 sq. m - 6-8 liters.
- Antimicrobial pharmaceutical drug "Trichopol". It is used when the first signs of illness are detected. For 10 liters of water, take 10 tablets and 40 drops of brilliant green. The frequency of treatment is every 14 days every 10 days.
Prevention of late blight:
- planting healthy seed;
- disinfection of tubers before germination;
- treatment with growth stimulants to increase plant immunity - "Epin", "Zircon";
- sorting tubers after germination;
- crop rotation;
- planting potatoes away from other nightshade crops;
- feeding with phosphorus and potassium.
To combat the Colorado potato beetle, use:
- fungicides: "Prestige", "Aktara", "Fury", "Alatar", "Klinmiks", "Iskra Zolotaya", "Commander", "Aktelik", "Corado";
- biological products: "Akarin", "Fitoverm", "Bitoxibacillin", "Antonem-F";
- a solution of laundry soap (100 g of shavings, 1 liter of ash can for 10 liters of water);
- birch tar solution (30 ml of tar, 30 g of soap shavings per 10 liters);
- tobacco dust (500 g per 10 liters of water), leave for 2 days, dilute in a ratio of 1: 2, add 40 g of shavings of laundry soap;
- bitter wormwood (300 g of fresh grass, 200 g of wood ash per 10 liters of boiling water);
- celandine (1.5 kg per 10 liters of water, leave for 3 days);
- elecampane roots (100 g of dry raw materials per 5 liters of boiling water, leave for 2 hours).
Prevention of the appearance Colorado potato beetle:
- high hilling of beds;
- mulching the site with black agrofibre;
- treatment of plants with the preparation "Universal humate";
- planting plants with a strong aroma (marigold, valerian, nasturtium), legumes, onions, garlic;
- regular weeding of weeds.
The appearance of a wireworm on the site is a lot of trouble gardeners. It is not very pleasant to see worms on potato tubers after harvest.
To combat the pest, use:
- chemicals: "Zemlin", "Barguzin", "Aktara", "Provotox", "Pochin", "Medvetoks", "Tabu", "Prestige", "Force";
- biological preparations "Metarizin", "Entocid";
- nettle infusion (500 g of grass per 10 l);
- infusion of wormwood and celandine (150 g of herbs per 5 l);
- infusion of mother and stepmother (100 g per 5 l);
- walnut leaves and onion peels in the holes;
- mustard powder for deboning tubers before planting;
- bait from pieces of carrots and potatoes soaked in any insecticide.
Prevention of the appearance wireworm:
- compliance with the rules of crop rotation;
- decrease in soil acidity: introduction of chalk, dolomite flour, slaked lime;
- attracting starlings, crows, blackbirds, turtle doves, rooks, wagtails, tits, ladybirds, ground beetles to the beds;
- planting potatoes after tomatoes, eggplants, peppers, beans, zucchini, cucumbers, flax, rye, alfalfa.
Collection, application and storage of crops
Rules for collecting ultra-early potatoes:
- The first digging is carried out 35–40 days after full germination, the last one at the end of August.
- A week before harvesting, the tops are cut and removed from the site. During this period, the peel becomes dense, which allows the crop to be stored longer.
- After digging, the tubers are left to "rest" for 1–2 weeks in a dry, dark place, then sorted and put into the cellar. The seed is left in the sun for landscaping.
- The storage and containers are washed and dried. The tubers are placed in ventilated containers: plastic or wooden boxes, nets, burlap. Optimum storage temperature - + 3 ... + 4 ° С, humidity - 70-80%.
Reference. After harvesting, complex biochemical processes take place in the tubers, accompanied by the removal of excess moisture, compaction of the outer shell, and healing of injuries.
The moderate starch content of Nandina potatoes allows it to be used for frying, cooking, baking, stewing. The pulp does not darken after cooking and cutting raw. The variety is grown mainly for the production of young potatoes.
Features of cultivation and possible difficulties
Variety Nadina is highly sensitive to cold... Air temperature below -4 ° С leads to wilting of the tops and death of tubers.Ice crystals form in potatoes and destroy cells. Frozen tubers begin to rot. For this reason, potatoes are planted after the threat of night frosts has passed. For safety net, in the first two weeks, the beds are covered with black agrofibre.
Tips and Feedback
Reviews of the Nandina variety are mostly positive... The culture is appreciated for its early ripening period, the ability to do 2-3 digging, and unpretentious care.
Vera, Zavolzhye: “When planting early varieties of potatoes, I focus on the soil temperature. If the soil has warmed up to + 10 ° C, you can safely plant the tubers. Nandina is one of those varieties that is afraid of night frosts, so I cover the beds with foil as a safety net, and after the stable warm weather is established, I remove them. I like this potato for its undemanding care. I fertilize the site in autumn with humus, and in spring with wood ash. As my experience shows, this is enough to gain green mass and form tubers ".
Dmitry, Pyatigorsk: “I grow the Nandina potato variety for an early harvest. His productivity is high, taste is on top. I noticed that the most delicious potatoes are getting closer to August. I use chicken manure as a fertilizer, fill it with water for a day, then add ash. I mix and dilute with water in a ratio of 1:10. I water the area with these composition before planting. During the flowering period, I water it once and feed it with nitrophos. Tubers are formed large, in large quantities ".
Conclusion
The Nandina variety is able to quickly adapt to growing conditions, subject to the rules of planting and care. Planting is carried out in light, nutritious soil, previously germinated and treated in a disinfecting solution tubers.
The culture does not need strict adherence to the irrigation and top dressing regime. Moistening the soil is carried out during the drought period once every 10 days, and fertilizers are applied before planting, and taking into account the appearance of the tops. Dead bushes are fed with minerals, avoiding organic matter, the excess of which leads to a rapid gain of green mass and grinding of tubers.
