Okra sexual warmth, heat resistance, cold, seed germination, growth and development of suitable temperature 25 ~ 30 °C, optimum flowering temperature 26 ~ 28 °C, the average monthly temperature below 17 °C affect the flowering results, the night temperature is lower than 14 °C Poor growth; okra happy light, not only requires a long time of light, but also have a certain light intensity, adequate light, favorable growth and development, fruit set rate, rapid fruit development, high yield, good quality; Okra drought, moisture, intolerance涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 结果 , , ,. Nitrogen, phosphorus and potassium are complete. Nitrogen is predominant in the early stage of growth, and phosphorus and potassium are the main components in the middle and later stages. Excessive nitrogenous plants are susceptible to long delays and flowering results. Nitrogen-deficient plants have poor growth and reduced yield. Cultivation techniques (a) cultivation season. In the Yangtze River basin and southern China, okra can be cultivated in spring, summer and autumn, but it is mainly spring sowing. Sowing from March to April, harvesting from May to September; sowing from May to June, harvesting from July to October; sowing in July and harvesting from September to November. Early sowing should use greenhouses, small sheds or mulching to cover cultivation, and open season cultivation in the main season. (b) Variety selection. In the Yangtze River basin and southern China, it is advisable to use varieties such as “Taiwan Wufu”, “Tokyo Pentagon”, and “Beautiful Pentagon”. Generally, the yield per mu is 1,000 to 2,000 kg. (c) Site preparation (opening). Base fertilizer. After the harvest of the former crop, the soil shall be deep-turned 10 to 15 days in time, and the crop shall be smashed. The hatch is generally 1.3 meters (4 feet); the depth of the pit is 25 to 30 centimeters; 2000 kg, compound fertilizer 30-40 kg as the base fertilizer, fertilizer and soil should be fully mixed, 3 to 5 days after sowing or planting. (D) sowing nursery. Okra is a straight root system, and its root regeneration ability is weak. Spring cultivation is often used for live cultivation. Okra seed coat is hard, sowing seeds must be soaked for 24 hours before sowing, every 5 to 6 hours cleaning water change l, after removal, placed in 25 ~ 30 °C under the environmental conditions of germination, germination after about 3 to 4 days after sowing. Seed sowing seeds is appropriate, sow seeds 3 to 4 per nest, cover soil 2 cm thick, about 5 to 6 days to sprout unearthed. Early spring cultivation can be used nursery transplanting, seedling age 30 to 40 days. (five) Dingmiao or planting. When the seedlings are unearthed, they should be seeded with weak seedlings and diseased seedlings when they are unearthed. When the seedlings have 2 to 3 true leaves, they should be planted or planted in groups. Each compartment should be planted in two rows with a row spacing of 66 cm, a nesting distance of 40-50 cm and planting between 2000-2500 per mu. Nests, 2 plants per pot. After earthing, the soil should be cultivated once. After planting, sufficient roots should be removed to facilitate survival. (6) Field management. Okra plant tall, easy to lodging, so the early production should be diligently cultivating weeding and earthing 2 or 3 times until the closure time. Top dressing is mainly organic manure, suitable with P and K fertilizers: apply Ding Miao for 5 to 7 days after setting seedlings or planting, 1000 kg of manure and livestock waste per acre, and 3 to 5 kg of urea; the early stage of flowering (Ding Miao or 25 to 30 days after planting) The second application of fertilizer was applied to 1500 kg of artificial manure per acre and 5 to 8 kg of potassium chloride; the top dressing of flowering results was re-applied to 1 additional fertilizer, and 2,000 kg of manure was excreted per acre. Potassium chloride 8 to 10 kg. Afterwards, according to the growth of the plants, fertilizers should be topdressed, but they should not be abused so as to avoid vegetative growth and reproductive growth disorders. During the flowering period, “In order to improve the ventilation and light transmission conditions, the old leaves of the harvested young fruit should be cut off in time. The okra is hi wet, requiring high air and soil moisture, especially when the flowering results cannot be short of water. Timely supply of sufficient water to promote the rapid expansion of tender fruit, but the water can not be too much, timely drainage after heavy rain, in order to facilitate the normal growth of plants, increase the yield per unit area.(VII) pest control.Okra is very resistant to disease, In general, there are few diseases; the pests are mainly aphids, and they are treated with 50% anti-inflavor WP 2000-3000 times or 21% killing fleas 6000 times. (8) Harvesting Okra begins from section 4-8 Flowering results of the festival, under appropriate temperature conditions, flowers can be harvested 2 to 4 days after flowering. Generally, the tender fruit grows to 6 to 8 centimeters in length, about 12 grams in weight, and can be harvested and marketed. Early production is low, fiber harvesting is too late to be eaten, harvesting is usually done 2 to 3 days before harvest, harvesting is generally harvested once a day or every other day, and harvesting is usually done 3 to 4 days in the middle and late harvests. Okra has stems, leaves, and fruits Wool or spines, harvesting should wear gloves, otherwise the skin stabbed, itchy general yield per acre from 1000 to 2000 kg. China Agricultural Network Editor
