Features of planting and growing

The hybrid is grown by seedling and sowing seeds in open ground. The key points of agricultural technology are adherence to the planting scheme and timing, timely watering and proper feeding.

Preparing for landing

An even, sunny area without shading is chosen for the culture. They dig up the ground since autumn. Floodplain soils and chernozems - to a depth of 25–30 cm, peat bogs - up to 30–35 cm. In spring, the soil is loosened and humus is applied (5–8 kg / m²).

The seeds of the SB 3 hybrid are calibrated and treated with a fungicide, therefore they are not additionally soaked or disinfected.

Seedling preparation

For seedlings, take a neutral substrate or make a nutrient mixture on their own:

• sod land - 1 part;
• humus - 1 part;
• peat - 1 part;
• wood ash - 1 tbsp. l. for 1 kg of mixture.

Prepare trays and plastic cassettes 4.5 × 4.5 × 3 cm. The most convenient container is peat cups. In them, seedlings are planted in the ground with minimal risk of plant deformation.

The trays are filled with a nutrient mixture by 5–10 cm. Grooves are made with a distance of 3 cm, deepening by 1 cm, the soil is moistened. The seeds are planted at 2 cm intervals, sprinkled with earth and slightly compacted. 1 seed is planted in separate containers.

Important! Seeds for seedlings are sown from late March to mid-April. Properly grown seedlings should be no higher than 25 cm, have 5-6 leaves.

The temperature is maintained at + 15… + 18 ° C before germination. After the seedlings are rearranged in a bright place with a temperature of + 7 ... + 10 ° C, gradually increasing it to + 15 ° C. Water the plants in moderation. Seedlings from the trays dive with the appearance of 2 true leaves. A week before planting in open ground, the temperature is lowered to + 10 ° C.

Seedless landing

In open ground, seeds are sown at the beginning of May according to the scheme 60–70 × 50 cm. The seeding depth is 1.5–2 cm. From 3 to 5 seeds are placed in each hole.

They are covered with a mixture of earth, humus and peat in equal parts. The beds are watered and covered with foil. With the appearance of the second true leaf, the film is removed, the seedlings dive.

Soil requirements and predecessors

Any soil with neutral or slightly alkaline acidity is suitable for cabbage. The best will be loam.

Favorable predecessors:

• cereals;
• beet;
• cucumber;
• tomatoes;
• potatoes;
• legumes;
• pumpkin.

Unfavorable:

• onion;
• carrot;
• peas;
• turnip;
• radish;
• all cruciferous species.

In one area, cabbage is re-planted after 5 years.

Landing rules

At the age of 45–50 days, seedlings are transplanted into open ground. This usually happens in the second decade of May, when the temperature has settled at + 10 ° C.

Plants in peat cups are planted together with containers, from plastic trays - by transshipment. To prevent the earthen lump from disintegrating, the seedlings are watered 2 hours before planting. They are planted according to the scheme 60-70 × 50 cm.

Work order:

1. Wells are prepared in the morning. Depth - 15–20 cm, diameter 10 cm greater than the diameter of the root system.
2. A mixture of 1 tbsp is added to each well. humus, 1 tbsp. l. chalk and handfuls of wood ash. Sprinkle a little earth on top and moisten 1 liter of water. Planting holes are left for 2-3 hours so that the earth settles.
3. For the prevention of bacteriosis prepare a clay chatterbox with a solution of "Fitolavin-300" (0.3-0.4%). The roots of the seedlings are dipped in it along with the earth.
4. Plants are planted down to cotyledonous leaves. The pits are filled in so that the apical bud remains above the ground, and watered. After an hour, the wet soil is sprinkled on dry: this will slow down evaporation and prevent the formation of a crust.

Growing features

In southern regions and areas with a mild climate, cabbage is sown in open ground. For areas with cold climates, the seedling method is recommended. In a very short summer, seedlings are planted in greenhouses.

The nuances of care

The main focus in crop care is to maintain the moisture in the upper soil layers. A rational option would be drip irrigation.

An alternative way is mulching. Mulch prevents moisture evaporation, crust formation and weed growth. Dry straw, rotted sawdust, manure, agrofibre are used for cabbage.

Watering

Young seedlings are watered at the root, 1 time every 2-3 days, using 1 liter per plant. With the beginning of the formation of heads of cabbage, moisture is reduced to 1 time per week. Water consumption - 10-12 l / m²... Stop watering the planting 2 weeks before harvest.

Loosening and hilling

The soil is loosened for aeration and as a pest control measure.

Work order:

• after rooting, the seedlings are loosened to a depth of 4-5 cm;
• a week later, repeat with a depth of 6–8 cm;
• further - after each watering, until the leaves close.

Hilling stimulates root growth. For this, the earth is raked to the plant to the lower leaves. The procedure is performed 20 days after planting, once every 3 weeks, until the leaves close.

Attention! In rainy weather, waterlogged soil is removed from the stem to prevent rotting.

Top dressing

The hybrid is fed at the initial stage of setting heads and 2 weeks after. 10 g of urea, 30 g of superphosphate, 15 g of potassium chloride are diluted in 10 liters of water. For each plant, use 0.5 liters of solution.

Measures to increase the yield

Additional nutrition will help increase the yield by 30%. Before planting, "Mag-Bor" is introduced into the soil (1 tbsp. L. Per 1 m²). During the season, 2-3 foliar dressings are carried out with a complex of microelements (for example, "Cytovite").

Diseases and pests

The causes of hybrid diseases are extreme heat (above + 30 ° C), flooding of the site, contaminated soil, insects.

Possible diseases and pests:

1. Slimy bacteriosis - mucus appears, the leaves rot and fall off, the head of cabbage softens. As a preventive measure, the plants are powdered with wood ash. For treatment, drugs "Trichodermin", "Planriz" are used.
2. Vascular bacteriosis - growth slows down, the veins on the leaves darken, forming a mesh, the leaves turn yellow and dry, the heads of cabbage are deformed. For prevention, cabbage is sprayed with a solution of brilliant green (15 drops per bucket of water). Apply "Planriz" and "Trichodermin".
3. Powdery mildew - spots with a white bloom appear on the leaves. Plants are sprayed with Fitosporin or 1% Bordeaux mixture solution.
4. Cabbage fly - the larvae damage the roots. Crops are treated with Thiofos. Sprinkle the soil with mothballs or tobacco dust.
5. Cabbage aphid and cruciferous flea - feed on leaf juice. The culture is sprayed with a tobacco-ash solution (200 g of ash and tobacco per bucket of water). Dill, garlic, and parsley are planted next to the cabbage.

Harvesting and storage

Harvested in September.The heads of cabbage are pulled out together with the stem and allowed to lie down in the beds for 2-3 days, so that the integumentary leaves wither. Then the stumps are cut off, leaving 2-3 cm, the integumentary leaves are not removed.

Cabbage is laid out on wooden flooring or in boxes with perforated walls. Store in a dark room at a temperature of -1 ... + 5 ° C and an air humidity of 90%. The keeping quality of the crop is about 4 months.

Growing difficulties

The main problem when cultivating cabbage is that the heads of cabbage are not tied. There are many leaves, the plant looks healthy, but stretches strongly up and does not form forks.

Possible reasons:

• late sowing dates;
• thickening of the planting;
• overdose of nitrogen fertilizers;
• waterlogging or insufficient watering.

To remedy the situation, the rosette leaves are collected in a bud and secured with a soft elastic band or cloth tape. This encourages the cabbage to form forks.

For additional stimulation, the plants are sprayed with a boric acid solution (15 ml per 10 l of water). They normalize watering by maintaining optimal soil moisture.

Advice and feedback from experienced gardeners

Most vegetable growers speak positively about SB 3 F1 cabbage, noting the high yield and excellent taste:

Lyudmila, Kotelnich: “We grow several types of cabbage and keep it until January. The most unpretentious of them is the hybrid SB 3. For many years I have been using only it for fermentation. "

Svetlana, Kaluga: “I planted different varieties, read the descriptions - I chose SB-3 cabbage .. It grows without problems, I am happy with the harvest, I fight mainly with the cruciferous flea. Very good anti-flea shampoo for animals (2 tablespoons per 10 liters of water). For prophylaxis, I spray it once a week. "

Conclusion

Cabbage SB 3 F1 is a mid-season hybrid for cultivation throughout Russia. Differs in cold resistance, heads of cabbage do not crack under any weather conditions. The crop is valued for the one-dimensionality of the forks and high yield rates. Vegetable growers consider this cabbage to be one of the best for pickling.
