What is the suitable plant and row spacing for cucumber cultivation?

Cucumber is a common vegetable that can be eaten raw or cooked. Many people have experience growing cucumbers, so what is the plant and row spacing for cucumber cultivation? What are the cultivation techniques?

1. What is the plant and row spacing for cucumber cultivation?

Cucumber cultivation requires planting in wide and narrow rows, with a narrow row spacing of 40 cm, a wide row spacing of 80 cm, and a plant spacing of 25-30 cm.

2. Cucumber cultivation techniques

1. Land preparation

For land preparation and fertilization, apply 5 cubic meters of decomposed organic fertilizer, 25-30 kg of superphosphate or 10-15 kg of diammonium phosphate (5-5 kg of superphosphate per cubic meter, 2-3 kg of diammonium phosphate per cubic meter). Before planting, plow and make beds 1.2 m wide and more than 15 cm high, and cover with plastic film.

2. Planting

Determining the planting time: plant as early as possible on the premise that the plants will not be frozen after planting. In the Chengde area, planting is generally done in late April to early May. Temperature requirements: the minimum night temperature should be above 5°C, and the soil temperature at 0-10 cm should be above 12°C. For autumn open-field cucumbers, direct seeding is used. Plant according to the plant and row spacing mentioned above, using the dark water method for planting.

3. Field management

Trellising: set up trellises early after planting to prevent wind damage and leggy seedlings. Flower stand trellises or A-shaped trellises can be used, placed about 8-10 cm from the roots.

Vine tying: use the “8” figure method to tie the vines, preventing abrasion damage to the stems and vines and preventing the stems and vines from drooping. Tie once every 2-3 nodes, and do it in the afternoon; the stems and vines are easily broken in the morning. The tightness of tying should suppress the strong and support the weak; for plants with strong growth vigor, tie them somewhat more tightly, and keep the growing points at a uniform height.

Pruning and pinching: for varieties that bear fruit on the main vine, remove all side branches; for varieties that bear fruit on side vines, after fruit set keep one to two leaves and pinch off the tips, and remove all tendrils. When the stem grows beyond the top of the trellis, pinch off the tip in time to promote the growth of the lower fruits; the twisting method can also be used to inhibit upper growth.

Water and fertilizer: water and cultivate in time; the amount and frequency of watering depend on the weather and growth stage. Water to help seedlings recover 5-7 days after planting; before fruit set, control water, cultivate, and restrain seedling growth; when the root cucumber is 10-12 cm long, water to promote fruit development; during the fruiting period, water once every 5-7 days. The principle for topdressing is light first and heavy later, with small amounts applied frequently. Apply fruit-promoting fertilizer after the root cucumber has set, and apply heavy fruit fertilizer after the root cucumber is harvested. The use of organic fertilizer for topdressing is recommended.

In the cucumber cultivation process, controlling the row spacing well is the first step to success. I hope the above content can help everyone.
