How long does it take for cucumbers from sowing to fruiting? When will the seeds be sown? How do you plant it?

When it comes to summer vegetables, there are always cucumbers. However, with the development of planting technology, you can basically eat it all the year round. How long will it take for cucumbers from sowing to fruiting? When will the seeds be sown? How do you plant it?

How long will it take for cucumbers from sowing to fruiting?

In the case of natural growth, the time from sowing to fruiting ranges from 90 to 120, which goes through four periods: germination, seedling, first flower and fruiting.

1. Germination period

The germination period is from sowing to the appearance of the first true leaf, which takes 5-8 days. At this time, we should pay attention to the temperature and light to avoid rotten seeds caused by low soil temperature.

two。 Seedling stage

From the appearance of true leaves to 4-5 true leaves is the seedling stage, which takes about 30 days.

3. Early flowering stage

The early flowering stage is the period from 4-5 true leaves to the first female melon sitting (root melon), which takes about 25 days, in which the time of early-maturing varieties is short and the time of late-maturing varieties is long, so it is necessary to regulate the relationship between vegetative growth and reproductive growth.

4. Fruiting period

The period from the first fruit sitting to pulling seedlings is regarded as fruiting period, which usually takes 30-100 days, at this time to ensure adequate nutrients and water.

Different cultivation methods, varieties, planting conditions and management techniques will cause different growth time, so the specific time should be based on the actual situation.

When will cucumbers be sown?

Cucumber can be sown from January to March in early spring or from June to August in summer and autumn. Sowing it is best to choose full, pest-free seeds, soak in warm water of about 30 degrees for 4 hours before accelerating germination, after germination, more than 70% of the seeds can be sown, and mulch should be covered after sowing.

How to grow cucumbers?

1. Land preparation and planting

The plots that need to be planted with cucumbers are turned over, and then applied with rotten organic fertilizer, calcium superphosphate or diammonium phosphate (the specific collocation and application amount are determined according to the actual situation), and mixed with the soil to make border mulching. When the leaf temperature is higher than 5 degrees and the soil temperature is higher than 12 degrees, it can be planted. The planting density is controlled at 4000-4500 plants / mu and the plant spacing is 25-30 cm.

two。 Post-planting management

Cucumber should be inserted and tied in time after planting, and the distance between the rack and the root should be 8-10 cm; binding vine every 2-3 nodes should be carried out in the afternoon. The side branches of the main vine should be removed, the side vine should leave one or two leaves pinched after the melon, and all tendrils should be knocked off.

3. Fertilizer and water management

Timely watering and ploughing, the amount of water and the number of times depend on the weather and growth period. Slow seedling water is irrigated 5-7 days after planting; water control, ploughing and squatting before setting melon; watering and accelerating melon water when root melon is 10-12 cm long; watering every 5-7 days in fruit period. The principle of topdressing is light in front and heavy after a small amount of fertilizer is applied after root melon sitting, and full melon fertilizer is carried out after root melon harvest.

4. Pest control

Cucumber planting should pay attention to the prevention and control of downy mildew, gray mildew, powdery mildew, root-knot nematode and whitefly and other diseases and insect pests, it is best to spray pesticides in advance.

With the development of planting technology, there are not so many restrictions on planting cucumbers. For example, planting in greenhouse can be carried out all the year round, and it is not so difficult.
