An introduction to the growth of okra
Okra generally refers to okra, it is the mallow family of annual herbaceous plants, which likes warmth, widely cultivated in tropical and subtropical areas, in China's Guangdong, Hunan, Hubei and other provinces of the cultivation area is also extremely wide.
Okra growth cycle
Okra light-loving, heat-resistant and fear of cold, requiring a long period of light, but also drought-resistant, moisture-resistant, waterlogging intolerance, wide adaptability of the soil, but in the fertile and loose, deep, water- and fertilizer-retentive sandy loam soil grows well.
Okra is an annual plant, it takes 50-55 days after the seedling to flower, from flowering to harvesting as long as 85-120 days is enough, so the whole growing period in about 170 days.
Okra growth rate
Okra development from the seed, its seeds in the ground, will break the ground germination grow stem, then stem will grow a lot of leaves, until the May-September flowering period, it will be in the middle of the leaf axils will bloom a small flower, the flower pollination, will bear fruit, which is the common okra.
After the flowering and fruiting of okra, its growth speed up, growth enhancement, especially in high temperature conditions of the growth rate is faster, every 3 days in July that unfolds a true leaf, in September it takes 4~5 days to unfold a true leaf.
Okra growth cycle management
Okra planted in our country is also more, varieties and planting management directly affect the yield, the general okra mu yield in 4000 to 6000 pounds or so.
Temperature management:
Okrai will stop growing when the temperature is below 8 ℃, when the local temperature is about 15 ℃ when the seeds can germinate successfully, but it is the fertility of the appropriate temperature for the 25 ~ 30 ℃ between 26 ~ 28 ℃ blooming more, fruit development fast, high yield.
Fertilizer management:
1, okra in the planting before the need to apply sufficient basal fertilizer, which plays a basic role in the growth process of okra, so that there is sufficient nutrients in the soil, so that the okra can quickly root and germinate.
2, Qi seedling fertilizer three days after the emergence of the second fertilizer, the fertilizer is mainly for the seedling looks as neat, usually use urea to promote the growth of okra seedlings, an average of an acre of urea about one hundred kilograms of fertilizer, with the spraying of the way.
3, raise seedling fertilizer to wait until ten days or so after planting can be fertilized, can improve the survival rate of okra, shorten the growth time, so that the seedlings grow faster, earlier blossom and fruit.
