Cucumber pruning schemes in a greenhouse

Pruning cucumbers in the greenhouse is a must when growing vegetables: it allows you to get a big crop. Carrying it out according to a certain scheme and the correct formation of a cucumber plant makes it possible to achieve good results.

Pruning purpose

Pruning cucumbers in a greenhouse is the process of forming a cucumber bush to reduce its foliage and shoots to obtain maximum nutrition when setting and developing fruits.

It is easier to grow cucumbers in greenhouse conditions in unstable weather than in open soil, however, timely pruning of cucumbers in a closed greenhouse with limited space makes the growing process as convenient as possible and right.

There are several positive effects to pruning cucumbers when grown in greenhouse conditions; it:

• helps the plant retain its strength at the beginning of the fruiting stage;
• allows you to grow the fruit correctly forms;
• distributes the direction of mineral nutrition in the direction of the development of the ovaries, and not on an active set of green mass;
• reduces the thickening of cucumber plantings, preventing the occurrence and spread of diseases and fungal infections, providing air and improving heat ventilation of constructions;
• provides easy accessibility for caring for the crop when loosening, weeding and spraying.

Cutting cucumbers in the greenhouse saves time.

Basic approaches to pruning

Pruning should be carried out depending on the pollination method of the cucumber variety and the type of plant (bush or weave).However, there are a number of general principles on which any properly organized pruning of cucumbers in greenhouses is based:

• you should not cut the bushes earlier than 10 days from the time of planting in the greenhouse;
• before the procedure is carried out garter of bushes;
• use an exceptionally clean sharp tool to prevent infection;
• after they do not leave sticking stumps;
• all inflorescences and shoots in the lower part of the plants begin to be removed from the first 4-5 leaves;
• the top of the lashes is not torn off with your hands, but cut off with a tool.

Evaluate the quality of the crop will allow properly formed as a result of the bush. It should resemble an isosceles triangular figure in an inverted form. This form provides a uniform load on the center, giving air access to the lower leaves.

After trimming cucumbers, the bushes are periodically inspected, and the growing lashes are guided and attached to the trellis supports, repeating the action as they grow back. It is recommended to plan pruning in the early morning, so that by the evening, the cut-off point of the plant dries and takes longer.

Timing

The timing of trimming cucumbers in the greenhouse is related to the growth rate of stepsons. At the same time, the beginning of the event falls on the period when their length reaches 5-6 cm. A similar length of stepsons is considered optimal so that the vegetable crop is not injured.Exceeding the stepson lengths of 3-5 knots, the circumcision procedure is repeated.

Parthenocarpic species trimming scheme

The pruning scheme for parthenocarpic cucumbers in the greenhouse assumes that these varieties provide a sufficient level of illumination. Self-pollinated cucumbers do not need pollination by insects and are not dependent on artificial pollination.

Step-by-step instructions for the formation of self-pollinated varieties in one stem involves several steps.

• Initially, on the main stem, where 1 / 3 of the whole crop, from below remove all flower ovaries and lateral processes in the sinuses. Pruning starts from a growth distance of 2 leaves to 4, without removing the foliage. Such an event is carried out when the main stem has grown by 0.5 m. Pruning allows air to circulate freely below the vegetative part, preventing the development of root rot.
• A second pruning zone is located at a distance of 1 m in height. Lateral shoots are left with one cucumber and two leaves, removing the shoot’s growth point. Stepsons are left up to 20 cm long.
• The cucumber lash, which has reached the height of the greenhouse, is turned ring-wise and tied with twine to the ceiling structure of the greenhouse so that the shoot grows and bears fruit, but pinch the very top of the lash.At this stage, it is important not to direct the cucumber lashes down: such growth negatively affects the yield.

Bee pollinator pruning scheme

Growing cucumbers in greenhouses requiring pollination by insects occurs with the formation of a bush according to a scheme involving multi-stem pruning. These varieties of vegetables are distinguished by the fact that their main stem is full of male inflorescences or empty flowers, and female flowers grow on the lateral processes.

To activate branching of bee pollinated varieties, it is important to pinch the main stem over a 5-6 leaf.

Cutting of cucumbers pollinated by insects is carried out according to a certain technology, taking into account the characteristics of plants:

• until the appearance of the first ovary, lateral stepsons do not form;
• young shoots attract to the central stalk and wrap around it, while correctly cutting off interfering processes and mustaches;
• at the bottom of the stem in the sinuses of 2-3 leaves, pluck out the growth points of the lateral shoots;
• in the next part leave 1 fruit and a pair of leaves, removing the growth point of the shoots;
• in the middle part of the plant at a height of up to 1 m leave 2 fruits and 2 leaves;
• in the upper part leave 3 fruits and 3 leaves.
