Okra cultivation techniques

Okra, also known as Bushencao, okra and croissants, is a Malvaceae, an annual herb. Okra is mainly eaten with tender fruit and has the effect of strengthening stomach and intestines. It is a nutrient-healthy vegetable. In addition, flowers, seeds, and roots can be used as medicines. The planting technology is introduced as follows.

1, soil preparation and fertilization: Okra root system developed, deep into the soil, should be selected deep plowing layer, fertile soil, good light, drainage and irrigation convenient loam or clay loam.

Before sowing, the land will be plowed 20-30 centimeters, full-size basal fertilizer will be applied, about 3,000 kg of decomposed organic fertilizer will be applied to Mushi, 1000-1500 kg of fire-fighting soil or 15 kg of potassium sulfate, and the land that is easy to accumulate in rainy areas will be 1.2 meters wide. The sorghum, which has a 20-30 cm drainage ditch, can be planted on both sloping and drained lands in either flat or high ridge form. Because okra grows slowly in the early stage, harvesting starts from May to July. In order to increase land utilization, it can be intercropped with other vegetables and crops with short growth periods. For example, if the seedlings are planted in front of the slope, they will be planted in 0 days and the okra will emerge just before harvesting.

2, sowing nursery: The main live broadcast, soaking with 20-25 °C warm water sowing seeds for 12 hours before sowing, then dry, germination at 25-30 °C conditions under 48 hours, until half of the seeds can be sown when exposed, according to a row spacing 80 cm , 50 cm dig field spacing, seeding 2-3 per hole, cover soil. About 2,000 holes per acre are planted with about 0.5 kg of seed. Can also plant nursery colonization. Such as the use of nutrition cup seedlings stamped film, about 20 days can be transplanted. After planting or transplanting, precautions should be taken to prevent the ground tiger from harming.

3, field management: the first piece is really called when the first time when the seedlings start, remove sick and weak seedlings, when the 2-3 true leaves start Dingmiao, leave a strong seedlings per hole, Dingmiao should promptly after the cultivation of grass In the future, cultivating and weeding should be carried out frequently, and soil should be cultivated and pillars should be erected to prevent plant lodging.

Okra is a moisture-tolerant plant, with large plants and a large amount of water. After emerged and seedlings, it should be poured with water once in case of arid climate. Soil should be kept moist during flowering and fruit setting, especially when the high temperature weather in July-August is harvested. In the period, the demand for water is large, and the supply of moisture should be maintained. In the Dingmiao, results and full fruit period, the rate of topdressing 15 kg of urea or 500-600 kg of human excrement per acre will be promoted in order to promote high yield.

4. Harvest: Okra harvesting young fruits for timely harvest is the key to high yields. In the high temperature period, when the fruit grows to 8-10 centimeters after 5-7 days of flowering, it can be picked and listed. Generally, 1500-2000 kg of tender fruit can be harvested for 5-10 cm per acre.

5, pest and disease control: Okra diseases and insect pests are relatively small, mainly viral diseases, insect pests are mainly bollworm, aphids, thrips, etc., virus disease should be the main prevention, cotton bollworm mainly harm the fruit, available 50% phoxim EC 1500- Sprayed at 2000 times, the aphids and thrips are mainly harmful to the fruit pods and can be sprayed with 1000 times of 10% imidacloprid.
