Agrotechnics of cucumbers
The culture is grown by seedling and sowing methods. Direct seeding in the ground is carried out in late May or early June.
Due to the poor tolerance of picking, seedlings are grown directly in peat pots. This method eliminates root trauma. Saplings are planted in prepared soil in early June.
Plant care is simple. It is enough to provide moderate watering at the beginning of the growing season, and frequent watering during the fruiting period. The culture gratefully responds to organic, nitrogen, potassium-phosphorus fertilizers.
Seedling planting
Hybrid seeds do not need additional treatment with germination stimulants and disinfecting solutions. They undergo all the necessary processing in production.
Seedlings of cucumbers painfully tolerate a pick, so the seeds are laid out in individual pots of peat or paper with a volume of 0.5 liters. Fertile and loose soil is suitable for growing strong seedlings.To prepare it, you will need 2 parts of humus, 2 parts of peat and 1 part of sawdust or river sand. The components are mixed in a deep container and spilled with a dark solution of potassium permanganate, then 25 g of nitrophosphate is added.
The pots are filled with moist soil and the seeds are placed to a depth of 1.5-2 cm, a centimeter layer of peat is poured on top. The containers are covered with polyethylene and placed in a warm, dark place.
The film is removed after germination, the containers are taken out on the windowsill from the south side.
For irrigation, use settled water at room temperature. Watering frequency is once a week.
For feeding the seedlings, ready-made fertilizers "Aquarin" or "Kemira" are used.
The seedlings are ready for transfer to a permanent place after 2-3 true leaves have formed.
Direct sowing in the ground
They begin to prepare the soil for sowing seeds in the fall: they dig up and bring in a bucket of cow humus. In the spring, the soil is loosened and fed with ammonium nitrate - 20 g, superphosphate - 30 g, potassium sulfate - 15 g per 1 m² two weeks before sowing.
The optimum soil temperature is not lower than +8 ° С, the air temperature is not lower than +10 ° С. Sowing scheme - 50x30 cm, seed placement depth - 2-3 cm.
The soil is covered with black agrofiber to protect it from frost.
Council. Sow seeds in moist soil for quick germination.
Care
Cucumber care rules:
- thinning seedlings and removing weak shoots;
- at the initial stage of vegetation, plants are watered once a week, from the moment of fruiting, the frequency is increased to 3-4 times by 2.5-3 liters per 1 m²;
- after each watering, soil is loosened and weeds are removed;
- with a delay in development, the bushes are fed with nitrogen-containing fertilizers;
- in addition to nitrogenous dressings, cucumbers are fertilized with organic matter, potassium and phosphorus;
- the crop is harvested as the greens ripen to support abundant fruiting.
Top dressing scheme:
- the first - 14 days after sowing (planting): solution of chicken manure 1:15;
- the second - during the flowering period: 10 g of ammonium nitrate, 10 g of superphosphate, 10 g of potassium salt / 10 l of water;
- the third - during the fruiting period: 25 g of potassium nitrate / 10 l or 50 g of urea / 10 l.
Reference. The infusion of wood ash (300 g per 10 l) can be used for foliar dressing during the entire growing season of cucumbers.
The nuances of growing and possible difficulties
The Claudine f1 hybrid is called the improved form of the Claudia f1 cucumber. The culture is characterized by unpretentious care, resistance to heat and cold.
Like any other bunch-type cucumber, the plant needs the correct shaping of the bushes:
- all shoots and flowers are removed from the leaf axils;
- one ovary is left in the axil of the fifth leaf;
- in the sinuses of 7-10 leaves, two ovaries are left;
- the stem is thrown over the trellis;
- pinch the top of the head 1 m from the ground.
This procedure is called "blinding". It is carried out with the aim of extending the fruiting period, improving disease resistance.
From mid-August, the bushes are spud to stimulate the growth of new roots. For replenishment, use: 1 liter of milk serum and 25-30 drops of iodine, boric acid solution (10 g / 10 liters of hot water).
Diseases and pests
Claudine cucumbers are resistant to powdery mildew and tobacco mosaic virus, tolerant to downy mildew (peronosporosis).
Signs:
- tiny brownish and yellow spots on the leaves;
- purple-gray bloom on the reverse side;
- yellowing and falling of leaves.
The reasons:
- excessive humidity and air temperature below +9 ° С;
- watering with cold water;
- increased alkali content in the soil.
For prevention:
- the soil is dug up and disinfected with copper sulfate or "Fitosporin";
- infected bushes are dug up and burned;
- the beds are regularly loosened and weeded;
- observe the rule of crop rotation.
If infection could not be avoided, they are used for treatment:
- chemical preparations: 0.5% solution of Bordeaux liquid, "Oxyhom";
- folk remedies with ash, potassium permanganate, milk whey and iodine.
Folk remedies recipes:
- 10-15 drops of iodine, 1 liter of whey, 9 liters of pure water. The bushes are processed once every 1-1.5 weeks.
- 500 g of wood ash is mixed into 1 liter of hot water and infused for 3-4 hours. Then the mixture is filtered through cheesecloth and the volume is adjusted to 10 liters. The bushes are irrigated once every seven days.
- Add 1 g of potassium permanganate to 10 liters of water and spray the bushes with a solution once every 15 days.
Insecticides help to fight the melon aphid, bear, whitefly and spider mite on the site: Fitoverm, Komandor, Aktara, Nemabaktin.
Slugs are collected by hand at night, traps are set from beer cans, tobacco shag and hot peppers are scattered on the beds, the bushes are treated with a solution of ammonia (4 tbsp. L / 10 l).
Harvesting and application of the crop
Harvesting begins about 40 days after the first shoots appear. The hybrid is amazingly productive. The fruits do not barrel, even if they are overripe on the bushes.
Cucumbers are suitable for fresh consumption, but completely unsuitable for pickles and salting because of the thin skin. They get very soft in the jar.
When assembled, cucumbers are stored for up to three weeks in a cool place.

Reviews
The impressions of the gardeners from growing the "Dutchman" are mostly positive. They note the external similarity with the Claudius hybrid, but the taste is much higher.
Olga, Balashov: “Claudine's cucumber is my favorite. The culture is liked for its undemanding growing conditions, easy care and excellent taste. The seedlings seem weak, but after feeding with nitrogen they are actively gaining green mass. The cucumbers are delicious, juicy, the skin is thin. "
Alexander, Stary Oskol: "I have been growing this Dutch hybrid on my site for three years. For all the time with him there were no problems. Last year, the summer was cold and rainy, and the bushes were hit by downy mildew. I dealt with the problem with the help of milk whey with iodine. "
Victor, Balabanovo: “Claudine is a great hybrid for growing in a greenhouse. I form bushes as they grow, remove stepchildren and flowers, bring them into one stem. For feeding I use chicken manure, ammophos, potassium and phosphorus. The yield is consistently high until the onset of cold weather. One drawback - cucumbers are not suitable for pickling. Because of the thin skin, they become very soft. "

Conclusion
Claudine hybrid cucumbers have gained well-deserved popularity due to their excellent taste, ease of growing and subsequent care, high productivity and a long fruiting period. Parthenocarpic does not need additional pollination by insects, since it belongs to crops with a female type of flowering. The pollination process does not depend on male cells.
The plant is resistant to the main "cucumber" diseases, and when infected with powdery mildew, copper-containing preparations, ash, whey with iodine and potassium permanganate will come to the rescue.
The fruits are not prone to overgrowth, they have a pleasant sweetish taste, crisp flesh and thin skin.
