The technical introduction of okra is as follows:

1. Prepare the soil and fertilize. Okra has a well-developed root system and penetrates deeply into the soil. It is advisable to choose a loam or clay loam plot with a deep cultivation layer, fertile soil, good light exposure, and convenient drainage and irrigation for land preparation. Before sowing, plow the land deeply for 20-30 centimeters and apply sufficient base fertilizer. Apply about 3,000 kilograms of decomposed organic fertilizer, 15-20 kilograms of diammonium phosphate, 100-150 kilograms of plant ash or 15 kilograms of potassium sulfate per acre. In rainy areas in the south, the ground is made into high borders with a width of 1.2 meters, and drainage ditches 40-60 cm deep are opened between the borders. In the north, two cultivation forms are flat borders or high ridges. Sowing can be done from February to September in the south, and in early to mid-May in the north. Due to the slow growth of okra in the early stage, harvesting does not begin until July. In order to improve land utilization, it can be intercropped with other vegetables and crops with short growth periods.

2. sowing. Before sowing, soak the seeds in warm water at 20-25°C for 12 hours, then dry them, and germinate at 25-30°C for 48 hours. When half of the seeds are white, they can be sown. Dig holes in the previously prepared border with a row spacing of 80 cm and a plant spacing of 50 cm. First pour enough water, sow 2-3 seeds in each hole, and cover with 2-3 cm of soil. 2,000 holes can be planted per acre, and the seed amount is about 0.5 kg.

3. Field management. When the first true leaf unfolds, the first thinning is carried out to remove diseased and weak seedlings. Dine the seedlings when 2-3 true leaves are unfolded, leaving 1 strong seedling in each hole. After the seedlings are established, they should be cultivated in time to increase the ground temperature and protect moisture and eliminate weeds. In the future, cultivating and weeding should be carried out frequently and the soil should be cultivated to prevent the plants from lodging. Okra is a moisture-tolerant plant. The plant is tall and requires a lot of water. It should be watered once after emergence and establishment. Watering should be frequent during the flowering and fruit setting period to keep the soil moist. Especially in July-August, when the high temperature weather is at the peak of fruit picking, water demand is large, so the water supply should be maintained. However, when there is too much rain, water should be drained in time to avoid waterlogging. In addition, 15 kilograms of urea or 500-600 kilograms of human waste per acre should be applied three times during the seedling, fruiting and fruiting stages in conjunction with watering to promote high yields.

4． Harvest and pest control. When the fruit grows to a length of more than 5 centimeters, it can be harvested and put on the market. Generally, 1,000 kilograms of tender fruits of 5-7 centimeters and 1,500 kilograms of tender fruits of 7-10 centimeters can be harvested per mu. Okra has few pests and diseases, mainly viral diseases, cotton bollworms, bridge-building insects, aphids, thrips, etc. Prevention of viral diseases is the main focus; cotton bollworms and bridge-building insects mainly harm fruits, and 50% phoxim EC 1500-2000 times can be sprayed; aphids and thrips mainly harm fruit pods, and 40% omethoate can be sprayed 1500 times. .
