1. When the young seedlings break their hearts, they are the first seedlings and the weak seedlings. 2 to 3 true leaves when the second seedlings, choose to retain strong seedlings. 3 to 4 true leaves when Dingmiao, leaving 1 per hole. 2, weeding and weeding After the seedlings are unearthed or planted, the temperature is low, and the cultivator should be continuously cultivated twice to increase the ground temperature and promote the easing of seedlings. Before the first flower is opened, the middle cultivator is strengthened so that the seedlings can grow in order to develop the root system. After the flowering results, the plant growth speeded up. After each watering top dressing, the cultivator should be cultivated, and the cultivating soil should be cultivated before mulching to prevent the lodging of the plants. In the rainy and windy areas in summer, it is best to use bamboo sticks of about 1 meter, or branches inserted near the plants to prevent lodging. 3, watering and fertilizing 1 Watering Okra requires high air and soil moisture during growth. When the water shortage occurs within 20 days after sowing, artificial irrigation should be performed sooner or later. After the seedlings are slightly larger, they can be sprayed or furrowed mechanically. The summer season coincides with the harvest period of Okra, which requires large amounts of water and high surface temperature. Before 9 o'clock in the morning, it should be watered in the afternoon to avoid watering and rooting at high temperatures. Pay attention to drainage in the rainy season to prevent dead seedlings. The entire growing season is to keep the soil moist. 2 Top dressing On the basis of applying base fertilizer, top dressing should be applied properly, and nitrogen fertilizer should not be applied. The first time was Qimiaofei, which was carried out after emergence and applied 90-120 kg of urea per hectare. The second time is to raise the seedlings, set the seedlings, or plant the ditch after the planting, and apply 225-300 kg of compound fertilizer per hectare. During the flowering period, the fertilizer is applied once again. The human fecal dilute is 30,000 to 45,000 kg, or the NPK fertilizer is 300 to 450 kg. During the late growth period, a small amount of top dressing is applied as appropriate to prevent premature aging. 4, plant adjustment Okra under normal conditions, plant growth is strong, the main lateral branches thick, leaf hypertrophy, flowering results are often delayed. A twisting method may be adopted, i.e. twisting the petiole into a curved shape to control vegetative growth. In the middle and late fertility period, timely removal of the old leaves of the sections below the harvested fruits will improve ventilation and light transmission, reduce nutrient consumption, and prevent the spread of pests and diseases. Harvesting tender fruit timely picking up the heart can promote side branch results and increase early yields. Fruit picking in time to pick the heart, can promote the mature fruit, in order to facilitate the full grain, improve seed quality.
