What season is okra a vegetable?
Okra is usually harvested as a fresh and tender fruit. Early harvest will affect the yield, while late harvest will lead to excessive fiber, meat aging and quality decline. Okra is suitable for growing in a warm environment and has strong heat resistance. When the local temperature is stable at about 65438 05℃, seeds can germinate, and the suitable temperature for plant germination and growth is 25~30℃. Moreover, okra is very sensitive to light conditions, which requires long light time and sufficient sunshine.
Okra is propagated mainly by sowing. Soak the seeds for 65,438 02 hours before sowing, and then put them at 25~30℃ to accelerate germination. When 60% ~ 70% of the seeds begin to appear white, they can be sown. Generally, hole sowing is better. After sowing, cover the soil with 2 cm, and the seed consumption per mu is about 10kg. During the growing period of okra, it is required to maintain high air and soil humidity. When there is water shortage within 20 days after sowing, artificial sprinkler irrigation should be carried out in the morning and evening. In summer, plants need a lot of water and the surface temperature is high, so they need to be watered twice before 9 am and after sunset in the afternoon.
Planting method of okra:
First, sow and raise seedlings.
Okra likes warm weather. It can be planted directly in early April, or directly in the greenhouse in early March, and transplanted into the field after late frost. If direct seeding is adopted, sowing can be started when the ground temperature is higher than 15℃, or germination can be accelerated in a dark environment before direct seeding. Using plug seedling can effectively ensure the survival rate of okra, and it usually takes only 3 weeks to raise seedlings.
Second, colonization.
When the low temperature exceeds 15℃, okra can be customized after two true leaves. If it is a plug seedling, the true leaf is 1 ~ 2, and it is also necessary to ensure that the seedlings can be lifted from the plug. After the seedlings are raised, the roots will not be scattered. At this time, you can replant in the field and replenish water in time, and you can choose topdressing.
Third, harvest.
Generally, it can be harvested in the early morning or evening after planting for two months. The quality is the best at this time. If you want to keep the seeds, it is recommended to keep the plants with excellent characters.
