Klin technology for cucumber cultivation in greenhouses and plant protection

Peculiarities of cucumber cultivation using the Klin method

The Klin cultivation technology for cucumbers is focused on the most efficient use of the usable area in protected ground. Planting is carried out in long wooden troughs, which are installed in five rows throughout the entire greenhouse. The design allows for the compact placement of propagation material and obtaining a high yield even in relatively simple greenhouses.

  • Trough bottom width — 20 cm
  • Trough top width — 35 cm
  • Trough height — 20–92 cm
  • Trough length — 4.3 m
  • Planting density — 14–15 pcs/m²
  • Average yield — 18–19 kg/m²

From 20 to 24 plants are planted in one standard trough. Instead of traditional trellises for supporting the bushes, "soshki" (small wooden stakes) are used. The lower pointed end of the stake is inserted into the soil of the trough, and a cucumber leaf is carefully inserted into the upper cleft. During the growing season, 5–6 such supports are installed for each plant.

In Klin-type greenhouses, additional shelving can be installed. They are used to grow greens using the same agricultural technique as in early hotbeds or block greenhouses.

Bush formation using the Klin cultivation method requires strict adherence to the pinching scheme. This stimulates active branching and accelerates the formation of fruit buds.

  1. The first pinching is performed on transplants above the second true leaf.
  2. The second pinching is done on the side shoot of the second order above the first leaf.
  3. The third pinching is performed above the 7th–8th leaf.

Sanitary measures and plant protection

The protection of vegetable crops in protected ground is based on a combination of sanitary-preventive measures and chemical treatments. To prevent the mass development of diseases and pests, it is necessary to carry out sanitary work regularly. Timely implementation of agricultural activities reduces the risk of plant infection throughout the entire season.

  • Keep the protected ground area clean by completely clearing it of weeds.
  • Remove and burn all plant residues after harvesting.
  • Locate greenhouses and hotbeds away from places where rodents may live (warehouses, livestock facilities).
  • Regularly disinfect the structures of hotbeds and greenhouses.

When preparing soil mixtures, it is strictly forbidden to use soil on which related crops were previously grown. This leads to the accumulation of infections in the substrate.

Schemes for rodent control in greenhouses and hotbeds:

Treatment period Bait composition Preparation and distribution method
Autumn (after harvesting vegetables), early spring (when filling hotbeds), winter (in greenhouses) 1 part poison, 15 parts water. The bait is drenched with the solution.
Period of rodent activity 1 kg poison, 200 g sugar, 4–8 kg crumbled black bread. The components are mixed, formed into balls, and placed in areas where pests appear most frequently.
Period of rodent activity 1 kg poison, 1 g sugar, 30 g warm water, pieces of bread. Bread is soaked in the solution for 2–3 minutes (it is convenient to do this in a sieve) and placed in burrows.
Period of rodent activity 1–2 kg poison per bucket of water, wheat grains, rye, oatmeal, pumpkin or cucumber seeds. The seeds are soaked in the solution for 24 hours with constant stirring (or boiled for 30–40 minutes). After drying, they are placed in burrows or under bait heaps.

Chemical protection against pests and diseases:

Object of treatment Preparation and dosage Preparation and application technology
Thrips 7% anabasine sulfate or nicotine sulfate, 90 weight parts lime or chalk. Mixed in a tightly closed container immediately before treatment.
Spider mite (infusion) Pyrethrum extract with 1% pyrethrin (0.5% solution: 50 g of powder per bucket of water). Infused for 2–5 hours in a closed wooden or glass vessel. Carefully poured into the sprayer without sediment.
Spider mite (spraying at the first appearance) 50 cc of pyrethrum extract with 1% pyrethrin, 150 g of soap per bucket of water. Soap is dissolved in water, after which the extract is added to the foam.
Spider mite (alternative spraying) 20 cc of pyrethrum extract with 1% pyrethrin, 200 g of soap per bucket of water. Extract is added to the diluted soap immediately before starting work.
Spider mite (initial colonization stage) 20 cc of pyrethrum extract with 1% pyrethrin, 50 g of soap per bucket of water. Extract is added to the diluted soap immediately before spraying.
Seed (prevention of bacterial and fungal diseases) Formalin (200 cc per bucket of water or in a 1:300 ratio with water). Seed treatment is performed in the solution, then washed several times with clean water and dried thoroughly.
Bacterial and fungal diseases (growing season) Copper-lime solution (500 g copper sulfate, 500 g quicklime per 50 l of water). Lime is slaked in a small amount of water and brought to 50 l. Copper sulfate is dissolved separately and slowly poured into the lime milk with constant stirring.
Fungal diseases of all crops Calcium polysulfide (lime-sulfur decoction). In farm conditions, it is recommended to use a ready-made specialized solution.
