Okra and broccoli, cabbage, and purple cabbage have been selected by many netizens as one of the most healthy vegetable varieties in the modern era, so the planting prospects of okra in recent years are relatively broad. Okra is also called croissant, kidney soup. Today, Huinong.com mainly introduces the cultivation time and planting methods of okra.
First, planting time
In general, okra cultivation in the north and south is usually planted every year from April to June, and harvested from July to October. In terms of subdivision, North China is in the middle to late April to May.
Second, planting conditions
Soil
Okra has a wide adaptability to the soil, but it is more suitable for loaming and well-drained loam.
2. Lighting
Okra is sensitive to the sun and prefers a well-lit environment.
3. Moisture
Okra is not resistant to phlegm, and if the humidity is too large, it is easy to induce disease.
4. Temperature
Okra is warm, afraid of cold, and has strong heat resistance. When the temperature is 13 ° C and the ground temperature is about 15 ° C, the seeds can germinate. However, the suitable temperature for seed germination and growth period is 25-30 °C. The monthly average temperature is lower than 17 °C, which affects the flowering result. When the night temperature is lower than 14 °C, the growth is slow, the plant is short, the leaves are narrow, the flowering is less, and the flowering is more. 26-28 °C moderate temperature and flowering, high fruit setting rate, fast fruit development, high yield and good quality.
Third, the planting method
1. Soil preparation and fertilization
Prepare the plot for planting okra. After harvesting, we should carry out deep ploughing in autumn and winter and deep plowing 30 cm to deepen the mature soil layer, further loosen the soil and enhance soil water storage and fertilizer retention capacity. Before planting, the land will be fine, flat, loose and soft. The okra needs more fertilizer. It applies 5,000 kg of composted manure and 20 kg of compound fertilizer per acre. It is spread on the ground before the land preparation, and then deep into the soil, mix well and mix the soil and fertilizer, then ditch the ditch.
2. Sowing
Most of them use the live broadcast method, and they can also be transplanted. It is usually planted in mid-May, planted in mid-June, and harvested in August.
3. Interplanting, cultivating
After the emergence of the okra, the time to seedlings, 2 to 3 true leaves, remove the disease, weak, small seedlings, leaving 2 plants per hole. After the seedlings are unearthed, they should be cultivated and weeded in time, once every 10 days. Before the first flower is opened, it should strengthen the cultivating, appropriate seedlings, and promote root development. Cultivate the soil before mulching to prevent the plants from lodging.
4. Fertilizer water
Okra is more drought-tolerant and moisture-resistant, requiring higher air and soil moisture during growth, especially in the flowering stage. Okra has a long harvest period and the entire growth period is about 100 days. Appropriate topdressing on the basis of applying the base fertilizer, the first topdressing is carried out after emergence, and 6-7 kg of urea per acre is applied.
5. Set the leaves
In summer, it is necessary to set up a bracket to prevent lodging. A bamboo pole or branch with a length of 1 meter can be inserted next to the root of the plant to support the plant. In the early stage of growth, it is necessary to prevent excessive growth of nutrients, and in the middle and late stages, the old leaves of the sections below the harvested tender fruit are removed in time. The seed should be picked up in time to promote the ripening of the fruit to facilitate the fullness of the seeds and improve the quality of the seeds.
The above is the okra planting conditions and planting methods. Farmers who have planted okra or want to grow okra at home can learn more and refer to it. If there is good content, welcome to add!
