Cucumbers are planted in the first days of April in Southern Bulgaria, after the danger of frost has passed and the soil has warmed to 12-14 ° C. Cucumbers are grown in a single row at a distance of 130/25 cm or in a double row of 100 + 40/50 cm. 2.5 plants per sq.m. Bait against a hog is spread
The plants in phase 5 – 7 leaf are tied with polyethylene thread for wire construction, 180-200 cm high. 00 cm from each other.
Heat regime: Maintained in the first days after planting more moderate air temperature – 20-23 ° С, shorter but during the active growth until the beginning of fruiting it increases to 25 ° С, and during the period of active fruiting – 25-30 ° С.
Water regime: Initially watered once a week with 5-10 l / sq.m water, later with increasing temperature the watering period is reduced to 3-4 days, and the irrigation rate is increased to 10-15 and 20-30 l / sq.m. High humidity is maintained – 80 90%.
Diet: After forming 6 – 7 leaves, the plants are fed every 10 days with 5-8 kg / dca of ammonium nitrate until the first harvest and 10-12 kg / dca during fruiting. Twice a month 58 kg / dca of potassium sulphate are imported.
Plant formation: In seedless varieties (Sandra, etc.) the flowers up to 6 – 7 leaves and branches to bodies are removed. Properly formed knots are preserved in this area of the stem, and deformed (distorted) ones are removed. The vegetation top of the plants, once it reaches the bodies, is not removed, unlike the classical technology, but is transferred through the bodies and directed to the soil. Once it reaches 70-80 cm below the bodies, the top is broken. All new branches in this area are not removed, and their top is interrupted in the area of the main stem. Periodically aging leaves on the central stem after picking the fruit are cleaned.
In order to prolong the fruiting of the plants in July and partly in August, the secondary branches, developing from dormant buds on the central stem, are preserved in mid-June. Plants are allowed to grow freely.
The seed variety Gergana and others. are formed by removing the flowers and branches along the central stem to the 6th – 7th leaf, and the next branches to the bodies are interrupted after the first female flower or above the 3rd – 4th leaf. The female flowers and normally formed fruits in this area of the stem are preserved. The vegetation apex of the main stem is interrupted.
