1, choose the appropriate variety. At present, there are many kinds of pentagonal species in Taiwan, such as Nanyang, Wufu, Yongfu, Cuijiao and Qingfu.
2, a reasonable and dense planting. Okra like warm, heat-resistant, not frost-resistant, met the frost that is dead, hi bright light, intolerant yin, if planted too dense, mutual shade, then poor growth. To grow deep in the soil, loose and fertile land. Implementation of autumn soil preparation, deep plowing deep plowing, per acre Shi Man organic fertilizer 2000 kg, uniform application, can be appropriate increase in calcium, magnesium fertilizer. When the open field is planted with ridges, it is planted with a single row of 60 cm wide, with a distance of 50 cm, a depth of 2 to 3 cm per hole, and 3 to 4 grains per hole.
3, appropriate time seedlings Dingmiao. When exposed to a true leaf in the open field, the seedlings were planted once in a time. When 3 to 4 true leaves were planted, 1 strong seedling was left in each hole.
4, timely fertilization watering. Okra has a well-developed root system and strong absorptive capacity. When the plant height is 40-50 cm, the plant should be applied with 1 round of fertilizer and combined with cultivating soil. After recovering the first to the second fruit, 10 kg of urea is recovered per mu. In the late stage of growth, in order to prevent premature aging, foliar spraying of 0.3% potassium dihydrogen phosphate solution may be performed, spraying once every 5 to 7 days, and spraying 2 to 3 times. Okra is more tolerant to drought, less watering at seedling stage, suitable for cultivating seedlings before flowering, and promoting root elongation. In summer, the okra is harvested at the height of its harvest, and it is important to keep it moist, and it is usually 7 to 10 days. Water should be applied before 9:00 AM or in the afternoon after sunset to prevent watering and rooting at high temperatures. Pay attention to drainage in the rainy season to prevent dead seedlings.
5, rational adjustment of plants. Before the closure of the line, cultivators should cultivate the soil. In order to prevent the lodging of the plants, bamboo culms or branches of about 1 meter must be inserted near the plants. Okra dominated by the main vine, should be timely removal of lateral branches and reduce nutrient depletion. Appropriately remove the old leaves from the base after fruiting is started to facilitate ventilation and reduce disease. Fruit picking in time to pick the heart, can promote seedlings mature, in order to facilitate full grain, improve seed quality.
6, timely harvest storage. Harvesting is too early to affect production; too late, fiber is increased, meat quality is aging, quality is reduced, and food value is lost. Generally 7-8 days after the thank you. Harvesting when the tender fruit grows to 8 to 10 centimeters, the best fruit can be obtained. Use scissors to cut it when harvesting. Do not rub it with your hands as this will damage the plant. In order not to affect the yield, the plants in the lower part of the pods should be used. Okra can only be stored for 2 to 3 days at room temperature. The hot summer season has a high temperature, the water evaporates quickly, and the fruit surface is easy to age. Short-term storage should be immediately sent to a cold storage or refrigerator at 0-5°C within 2 hours of harvesting, so that it can be stored for 7 days.
