Planting method and time of cucumber

The planting time of cucumber is from January to March in spring and from June to August in summer and autumn. Cucumber planting method: good varieties without disease should be selected for planting in greenhouse, soaking seeds in warm water for about 6 hours, then spraying new high lipid film, and so on, after emergence, appropriate amount of base fertilizer should be applied to plant cucumber, keeping the temperature in the greenhouse at about 25 ℃. In the later stage, according to climate and growth conditions, appropriate water and fertilizer should be applied, and cucumber planting in greenhouse in winter should be actively controlled against diseases and insect pests.

Planting time of cucumber

Generally, it is planted from January to March in spring or from June to August in summer and autumn. seed soaking and direct seeding are required for spring planting, or direct seeding with plastic film mulching, soaking and planting in summer and autumn, and dry seed planting. It can also be planted in open field, spring greenhouse, spring greenhouse, autumn greenhouse, winter greenhouse and other places according to different varieties.

II. Planting methods of cucumber

1. Seed selection and soaking

The main results are as follows: (1) when cucumber is planted in greenhouse, excellent varieties with strong cold resistance and no disease should be selected. Before planting, each seedling bed should be selected in the land which is dry, ventilated, well drained and has not been planted with eggplant vegetables, and then allocated nutrient soil. The soil bed soil is decomposed organic fertilizer: compound fertilizer = 7VOVA 0.01, stir evenly and pour into the bottom water.

(2) remove the glutinous rice seeds, put them in hot water of 50-60 ℃, slowly stir to about 30 ℃, then soak the seeds for about 6 hours, remove them and dry them, spray the new high-fat membrane with 800x liquid.

(3) the soaked seeds were evenly scattered on the seedbed, covered with nutrient soil 1-1.5 cm thick after sowing, and then sprayed with new high-fat film to promote cucumber seedling emergence.

2. Prepare to plant

(1) rational planting: apply base fertilizer about 15 days before planting, so as to ensure a reasonable match of various elements (NPK ratio is 1-0.25), and then pour it into the bottom of the water, plan the greenhouse spacing, and plant reasonably.

(2) Film mulching heat preservation: due to the low temperature in winter, it is necessary to cover 2 sheds and 3 films, and the ground and cucumbers need to be sprayed with new high fat film, which is beneficial to heat preservation and pest control, etc., and the suitable temperature in the greenhouse should be kept at about 25 ℃ according to the slight temperature change every day.

(3) Water and fertilizer management: after cucumber planting, appropriate amount of water and fertilizer can be applied according to temperature changes and growth conditions, so as to ensure adequate nutritional balance.

3. Promoting flowers and strong fruits

When returning to normal seedlings after the completion of the plant, flower-promoting agents should be sprayed in time, which can effectively inhibit the exuberant growth of main and lateral buds and promote flower bud differentiation. Zhuanggutieling can be sprayed in the flower bud stage, young fruit stage and fruiting stage of cucumber, so as to promote the development of fruit and improve the quality and yield of cucumber.

4. Disease and pest control

When cucumber is planted in greenhouse in winter, the main diseases are anthracnose, powdery mildew, scab, angular spot, mosaic, downy mildew virus and Fusarium wilt virus. during this period, agricultural streptomycin, chlorothalonil wettable powder and 800-fold liquid new high-fat film can be used for control.
