The flowers of okra are borne singly in the axils of leaves, the pedicel is 1-2 cm long, sparsely hispid, the bracteoles are linear, the calyx is bell-shaped, the flower color is yellow, the petals are obovate, the okra prefers warm environments, afraid of the cold, heat-resistant strong, the suitable temperature for both seed germination and fertility are 25-30 ° C, but also drought-resistant, humidity-resistant, light-loving, waterlogging intolerant characteristics.

Flower morphology of okra

The flowers of okra are borne singly in the leaf axils, the pedicels are 1-2 cm long, sparsely hispid, the bracteoles are linear, sparsely hispid, the calyx is campanulate, densely covered with stellate velutinous hairs, the color of the flowers is yellow, and the base of the inner surface is purple, the petals are obovate, 4-5 cm long.

Temperature requirements of okra

Okra likes warm environment, afraid of cold, strong heat resistance, when the temperature reaches 13 ℃, the seeds can germinate, seed germination and fertility of the appropriate temperature are 25-30 ℃, if the average monthly temperature is lower than 17 ℃, will affect the flowering and fruiting of the plant, and the growth rate is slow.

Okra's growth habit

Okra drought-resistant, moisture-resistant, but intolerant of waterlogging, in the soil humidity is too large in the environment, it is easy to induce the standing wilt disease, and it is particularly sensitive to the light conditions, planting should be selected to the sunny plots of land to deep, loose and fertile, well-drained loam or sandy loam soil is appropriate.

How to plant okra

Okra is the main method of propagation for the sowing method, usually preferred to direct broadcasting, soak the seeds for 12 hours before sowing, and then placed in the environment of 25-30 ℃ germination, such as 60% -70% of the seed whitening hole sowing, 3 plants per hole, hole depth of 2-3 cm, sowing mulch 2 cm or so.
