Growth cycle of okra
Growth process: After the okra seeds enter the soil, they will break the ground to germinate and grow stems. Then, many leaves will grow on the stem. In the flowering period, that is, from May to September, small flowers will grow in its axils. After a while, its flowers will be pollinated, and it will bear fruits with a length of 10-25cm and a width of 1.5-2cm, that is, ordinary okra.
Growth cycle: Okra is an annual plant. Generally, it blooms 50-55 days after emergence, and it only takes 85- 120 days from flowering to harvest, so the whole growth period is about 170 days.
Flowering and fruiting time of okra
Okra blooms first and then bears fruit. Okra belongs to angiosperms, and no angiosperms can bear fruit directly. Flowers are the reproductive organs of angiosperms, which need pollination to bear fruit. So okra can't bear fruit without flowering and pollination.
The flowering period of okra is usually from May to September. Generally, flowers can bloom in about one to two months after planting, and management methods should be paid attention to during this period.
It usually takes about 50-55 days from planting to flowering of okra, and the specific flowering time depends on the climatic conditions in various places. Okra has a warm climate, suitable for planting from April to June, and can only be harvested in July-10.
The key points of planting okra in fruiting period: proper watering.
The reason why okra doesn't bloom is usually too much water. Too much water every time, the roots can't absorb the water in the soil. After a long time, the roots will rot and it is difficult to form flower buds, so they will not bloom.
rational application of fertilizer
In the flowering season, okra needs a lot of fertilizer. If you usually forget to apply fertilizer or apply fertilizer improperly, it will be difficult to blossom.
During the flowering and fruiting period of okra, attention should be paid to applying flower and fruit fertilizer first. Flower and fruit fertilizer is mainly composed of human manure and compound fertilizer, which can be fully and evenly mixed and applied in the field to ensure the satisfaction of nutrients needed by okra flowering, promote the growth and development of okra, and improve the yield of flowering and fruiting.
Planting temperature
The daytime temperature of okra is 28-32℃, and the nighttime temperature is 18-20℃. The average temperature below 17℃ will affect the flowering and fruiting of okra, and when the night temperature is below 14℃, the growth rate of okra is slow.
When the temperature is lower than 17℃, the respiratory ability of flower buds will be greatly reduced, the differentiation speed of flower buds will be slowed down, and the differentiation time of flower buds will be prolonged, making it difficult to form.
