When is the right time to plant cucumbers?

Cucumber is an annual vine or climbing herb belonging to the genus Cucurbitaceae. It is a widely grown vegetable that likes warmth and cannot tolerate cold. The suitable temperature range for growth is about 20-30℃. Too low a temperature will inhibit growth, while high a temperature may cause excessive growth and reduced fruit quality. So when is the right time to plant cucumbers?

1. Cucumber planting time

Cucumber planting is usually carried out from January to March in spring or from June to August in summer and autumn. When planting in spring, you can soak the seeds and germinate them before raising seedlings, or cover them with plastic film and sow them directly. In summer and autumn, you can use soaked seeds for direct sowing or dry seeds for sowing. Depending on the characteristics of different varieties, cucumbers can be grown in a variety of environments, including open air, spring greenhouse, spring greenhouse , autumn greenhouse, and winter greenhouse.

2. Cucumber cultivation technology

1. Variety selection and seed treatment

When growing in a greenhouse, you should choose high-quality varieties that are cold-resistant and disease-resistant. The seedbed should be set up in a well-drained area where eggplant vegetables have not been planted, and nutrient soil should be prepared with the ratio of decomposed organic fertilizer : compound fertilizer : trace elements = 7:3:0.01.

The seeds need to be soaked in hot water at 50-60℃, gradually stirred to 30℃, and continue to soak for 6 hours, then dried and sprayed with a new lipid film to promote germination.

2. Planting preparation

Apply base fertilizer 15 days before planting to ensure balanced nutrition (NPK ratio is 1:0.25:1). In winter, double-layer greenhouse film and triple-layer film should be covered, and the ground and plants should be sprayed with new lipid film to keep warm and prevent diseases. Adjust the supply of water and fertilizer according to temperature and growth conditions to ensure adequate nutrition.

3. Promote flowering and fruit development

After the plant resumes growth, spray the flower-promoting agent in time to control the growth of buds and promote the differentiation of flower buds. Spray fruit-enhancing agents during the bud stage, young fruit stage, and fruiting stage to promote fruit development and improve cucumber quality and yield.

4. Pest and disease control

When planting cucumbers in a greenhouse in winter, you need to pay attention to the prevention and control of anthracnose, powdery mildew, black spot, angular spot, mosaic disease, downy mildew, etc. You can use agricultural streptomycin, thiophanate-methyl wettable powder, new lipid film, etc. for prevention and control.

The above is an introduction to the planting time and key points of cucumbers. By following the above steps, cucumbers can be effectively planted and managed to improve yield and quality.
