What are the planting methods for potted okra?

1. Raising seedlings

(1) the okra seeds were soaked for 12 hours, then placed under 25: 30 ℃ to promote germination. About 24 hours later, the seeds began to sprout, and could be planted when 60% or 70% of the seeds were "broken mouth". Planting with hole sowing is appropriate, 3 plants per hole, and the depth of the hole is 2 cm to 3 cm.

Germination: sowing to 2 cotyledons flattening for germination, about 10 to 15 days. Sowing at 25: 30 ℃ and sowing for 4: 5 days, the soil can be germinated. It usually takes about 7 days for direct seeding seedlings to be unearthed in the open field, and plastic film mulching can produce seedlings 2-4 days in advance.

Seedling stage: it takes about 40 to 45 days from 2 cotyledons to several flowers blooming. After the general cotyledons fully expanded, after 15-25 days, more true leaves unfolded. A true leaf will occur every 2-4 days. The growth is slow in the seedling stage, especially when the ground temperature is too low.

(2) Seedling transplanting method: the seedling temperature was 25 ℃, germinated and unearthed in 4-5 days. The seedling age was 30-40 days and the seedlings were colonized with 2-3 true leaves.

If the harvest is not timely, the meat quality is aging, the fiber is increased, and the edible value of the commodity is greatly reduced. Generally, after the first harvest, it is harvested every 2-4 days at the initial stage, and the harvest interval is shortened with the increase of temperature. During the full fruit period in August, it is harvested every day or every other day. After September, the temperature dropped and harvested once every 3-4 days. When harvesting, it is appropriate to use scissors and put on gloves to avoid stabbing the skin with bristles or tumors on stems, leaves and fruits. Wash them with soapy water or roast lightly on fire to reduce the pain and itching. The tender fruit is usually harvested 4 days after flower fade, and the quality is excellent.
