Origin of okra

Okraut is also known as okra, croton, etc.. For the mallow family okra annual herbaceous plants, native to Africa, China also has wild species. Currently in Europe, Africa, the Middle East, India and Southeast Asia and other tropical areas are widely cultivated. Tender flesh, lubricated young pods for food, both fried, cold, for soup, but also for pickles, canned food, its nutrition is rich, per 100 grams of young pods containing protein 2.5 grams, vitamin A660 international units, vitamin B10.2 mg, vitamin C44 mg, calcium 81 mg, phosphorus 63 mg, iron 0.8 mg. Its tender pods contain viscous smooth juice, often eaten with stomach, laxative, liver and kidney effects. The seeds have a special flavor and can be used as a substitute for coffee. In recent years in Japan, Taiwan, Hong Kong, Shanghai and other markets are very popular, is the development of a huge potential for health care vegetables.

I. Characteristics

Root system is developed, strong absorption, erect stems, 1-2.5 meters high; leaves palmate five-lobed, petiole slender; hollow; flowers herbaceous, color showy, with ornamental value; fruit is a capsule, like a ram's horn, 8-20 cm long, green or red; seeds spherical, gray-black, thousand grains weighing about 55 grams.

Huangqiuquan sex like warm, heat and fear of cold, seed germination, growth and development of the appropriate temperature 25-30 ℃, flowering and fruiting period of the optimal temperature of 26-28 ℃, the average monthly temperature is below 17 ℃ to affect the flowering and fruiting, the night temperature is below 14 ℃ growth; Huangqiuquan light, not only requires a long time of light, but also to have certain Light intensity, sufficient light, favorable growth and development, high fruit set rate, fruit development, high yield, good quality; okra drought, moisture, flood intolerance, the results of the period requires sufficient water favorable fruit development, and vice versa, poor plant growth, poor fruit quality; okra on the soil adaptability, but to deep, fertile and loose, water retention and fertility of loam or sandy loam is appropriate; on the fertilizer requirements of nitrogen, phosphorus and potassium are complete. Pre-growth to nitrogen-based, middle and late to phosphorus, potash-based, too much nitrogen fertilizer plant is easy to grow, delayed flowering and fruiting, nitrogen fertilizer is not enough plant growth and yield reduction.

Two, cultivation techniques

1. Cultivation season. In the Yangtze River Basin and southern China, okra spring, summer and fall can be cultivated, but mainly spring sowing. March-April sowing, May-September harvest; May-June sowing, July-October harvest; July sowing, September-November harvest. Early sowing should be used in greenhouses, small arches or ground cover cultivation, the season to open-ground cultivation.

2. Variety selection. In the Yangtze River Basin and South China, it is appropriate to use "Taiwan Wufu", "Tokyo Wujiao", "beautiful Wujiao" and other varieties, generally 1000-2000 kg per 667 m2 output. -2000 kilograms.

3. The land for the border (open box). Apply bottom fertilizer. After the harvest of the previous crop, in time to deep turning kang soil 10-15 days, rake flat for the border, generally 1.3 meters (4 feet) to open the box; box ditch depth of 25-30 cm; per 667 m 2 hole into the rotted human and animal manure 2000 kg, compound fertilizer 30 a 40 kg as a bottom fertilizer, fertilizer and the soil should be fully mixed, 3-5 days after sowing or fixing the seed, the bottom fertilizer. -5 days after sowing or planting.

4. Sowing seedlings. Okra for the taproot system, root regeneration capacity is weak, spring open field cultivation is often used live. Okra seed coat is hard, before sowing shall be soaked for 24 hours, every 5-6 hours to clean the water change l times, take out and put in 25-30 ℃ under the environmental conditions of germination, about 3-4 days after germination can be sown. Seeds to hole sowing is appropriate, each nest sowing seeds 3 a 4, mulch 2 cm thick, about 5 a 6 days to germinate out of the soil. Early spring protected field cultivation can be used seedling transplantation, seedling age 30-40 days.

5. Seedling or planting. Seedlings out of the ground should be time to go to the weak, sick seedlings, when the seedlings have 2 a 3 true leaves when the seedling or planting, each compartment planted two rows, row spacing 66 cm, nest spacing 40 a 50 cm, per 667 m 2 planting 2,000 a 2,500 nests, each nest to stay planted 2 strong seedlings. Seedlings should be cultivated 1 time after planting, planting after applying enough root clear manure water, in order to facilitate the survival.

6. Field management. Okra plant is tall, easy to fall, so the pre-production period should be diligent weeding and soil 2-3 times, until the closed box. Fertilizer to organic fertilizer-based, appropriate with the application of phosphorus and potassium fertilizer: seedling or planting 5-7 days after the application of a seedling fertilizer, per 667 m 2 Shi rotted human and animal manure 1000 kg, urea 3-5 kg; flowering and fruiting in the early stage (seedling or planting 25-30 days after the application of the second fertilizer, per 667 m 2 Shi rotted human and animal manure 1500 kg, potassium chloride 5-8 kg. Kg, KCl 5-8 kg; in the blooming and fruiting period, reapply fertilizer once again, per 667 m2, with 2000 kg of well-decomposed human and animal manure and 8-10 kg of KCl. Later, according to the plant growth trend of appropriate fertilizer, but not indiscriminate, so as to avoid the phenomenon of nutritional growth and reproductive growth imbalance. During flowering and fruiting, "in order to improve the ventilation and light transmission conditions, should be timely cut off the old leaves of the sections that have been harvested over the tender fruit. Okra likes moisture, requires high air and soil humidity, especially when flowering and fruiting can not be short of water, we must supply sufficient water in a timely manner to promote the rapid expansion and development of young fruits, but the water can not be too much, and after heavy rain should be drained in a timely manner in order to facilitate the normal growth of the plant and improve the yield per unit area.

7. Pest control. Okra disease resistance is very strong, general disease is rare; pests are mainly aphids, with 50% anti-aphid wei wettable powder 2000-3000 times liquid or 21% kill kill 6000 times liquid prevention and control.

8. Harvesting. Okra from the 4th -8th section of the beginning of the section of flowers and fruits, under the condition of suitable temperature, flowers after 2-4 days after the harvest of young fruits, generally young fruits up to 6-8 cm long, about 12 grams of weight can be harvested on the market, harvested too early low yield, harvested too late fiber weight can not be eaten. Harvest pre-harvest generally 2-3 days harvest 1 time, harvest period generally every day or every other day harvest 1 time, harvest in the middle and late harvest generally 3-4 days harvest 1 time. Seed China reminds you: okra stems, leaves, fruits have bristles or thorns, harvesting should wear gloves, otherwise the skin is pricked, itchy unbearable. General per 667 meters 2 Yield 1000-2000 kg.
