2. Field management: The root system of okra is extremely developed, and its ability to absorb nutrients is also very strong. However, when the plant grows to about 50cm, it grows vigorously and needs to be fertilized immediately to ensure its nutrient supply. Okra has strong drought resistance, so it can be watered once a week. It is necessary to keep the soil moist at high temperature in summer, and it is easy to rot the roots if there is too much accumulated water. In rainy season, water should be controlled and drainage should be carried out in time. In order to ensure the fruit yield, redundant lateral branches should be cut off in time to reduce nutrient consumption, and diseased branches of old leaves should be cut off after fruit picking, so as to increase ventilation and reduce diseases.
3. Fruit picking and storage: The fruit picking time of okra is extremely important, and the fruit becomes tender too early, which affects the yield; However, the fruit is picked late and older, which reduces the edible value. Generally, the fruit picking time is one week after the flower withers. When the fruit grows to 8- 10cm, the fruit is the best. The picking time should not be at noon, but in the morning and evening. The storage of okra is also very important, and it is not suitable for high temperature storage. High temperature will accelerate its breathing and make the tissue perishable. It is best to store it in a cool environment of 7- 10 degrees, but not below 7 degrees, which will rot and change color.
4. Pests and diseases: Okra has fewer pests and diseases in vegetables, and occasionally insects invade. In the long rainy season, leaves will be diseased. After the weather clears, lime will be sprinkled around the plants in time to prevent the spread of diseases and cut off diseased branches and leaves.
