When will okra be planted?

Okra likes warmth and is afraid of frost. The whole growth period should be arranged in frost-free period, and the flowering and fruiting period should be in warm and humid seasons everywhere. Open field cultivation, sowing in April-June, and harvesting in July-65438+10. Sowing in North China is usually in the middle and late April to May. In northern cold areas, sunlight greenhouses and plastic greenhouses are often used to raise seedlings, and then they are planted in the fields after early spring and late frost. It takes about 60 days for okra from sowing to the formation of the first tender fruit. In the future, the whole harvest period will be as long as 60 ~ 70 days, and the whole growth period will be about 120 days.

Okra, also known as okra, is native to China and Japan. Like warm, humid and sunny environment, not cold-resistant, afraid of water accumulation.

It is suitable to grow in loose and fertile sandy loam with good drainage when the wind blows. Okra likes warm and light, and is resistant to heat and cold. It requires not only long illumination time, but also drought, humidity and waterlogging. Okra has wide adaptability to soil, but loam or sandy loam with deep soil layer, rich and loose soil layer and strong water and fertility conservation is suitable.

Planting okra requires attention:

1, sowing and seedling raising:

Okra is suitable for planting on the land with deep soil layer and loose and fertile soil layer. At the same time, apply sufficient base fertilizer. Generally, soil and manure are applied per mu.

2000 kg, cake fertilizer 100 kg. Nursery seedlings are usually planted in sunny seedbeds or solar greenhouses from the end of March to mid-April. Seedbed soil is prepared according to the ratio of vegetable garden soil, decomposed organic fertilizer and fine sand of 6: 3: 1, and the density is 10 cm. Because the shell of okra seeds is hard,

Therefore, seeds should be soaked for 24 hours before sowing, and then germinated at 25-30℃ for 4-5 days, and the seedling age is 30-40 days, that is, 3-4 leaves should be sown when they are young. Generally, the live broadcast is carried out from early April to mid-May, with 1 m as the boundary, two lines on each side, the density is 50 cm square, and 2-3 seeds are sown in holes. Plastic film mulching cultivation can be sown 4-6 days earlier. When the seedlings grow to two leaves, they should be thinned, leaving only one strong seedling in each hole, and the seedlings should be fixed when there are 4-5 leaves.

2. On-site management:

(1) Okra has developed roots and strong absorption capacity. When the plant height is 450 cm, the fertilizer should be applied 1 time, and the primary and secondary fruits should be harvested in combination with intertillage and ridging, and then the urine per mu should be 10 kg. In the late growth stage, in order to prevent premature aging, 0.3% potassium dihydrogen phosphate solution can be sprayed on the leaves every 5-7 days 1 time for 2-3 times in a row.

(2) Abelmoschus esculentus is drought-tolerant, so it can be watered less at seedling stage and squatted properly before flowering to promote root elongation. Water at any time during drought, and keep the border moist in summer. Generally 7- 10 days 1 time. Appropriate watering in the late growth stage. There is much water and high temperature in rainy season, which easily leads to waterlogging and root rot. It is necessary to clear the ditch and drain water in time.

(3) Abelmoschus esculentus mainly has main tendrils, and the lateral branches should be removed in time to reduce nutrient loss. After fruit picking, properly remove the old leaves at the base to facilitate ventilation and reduce diseases. Pay attention to cultivating soil in rainy season to prevent plants from lodging.

3, pest control:

Okra has fewer pests and diseases, and occasionally there are aphids, borers and cutworms. To control aphids and stem borers, 2.5% dichlorvos can be sprayed 3000 times or 80% dichlorvos emulsion 2500 times. To control cutworms, 80% dichlorvos 1500 times solution or 90% trichlorfon 500 times solution can be injected around the rhizosphere to kill larvae. In the rainy season, there are many diseased spots on branches and leaves. After the weather clears up, lime should be sprayed near the base of the plant in time to prevent the spread of the disease.

How to grow okra? Can you plant it at any time and in any season?

Okra (scientific name: okra): Also known as okra, croissant, coffee Huang Kui, eggplant and okra, it is also called "foreign pepper" among the people. Originated in Africa, it was introduced to China from India in the early 20th century, and it was mostly found in southern China. Its edible part is pod, which is divided into green and red. It tastes crisp, tender and juicy, smooth but not greasy, with unique flavor, and seeds can be pressed for oil.

Like warm climate, not cold-resistant, planted in deep fertile soil and sunny land. Okra is usually planted in March and germinates in 3-5 days. The seedling stage lasts for more than 40 days and begins to bear fruit in May. The growth cycle is generally more than 7 months.

Okra likes warm and sunny environment. Its cold tolerance is slightly different due to different varieties. Hibiscus and Hibiscus multiflora can overwinter in Beijing. Okra needs covering to protect it from wintering, or digging out its perennial roots.

Okra is stored in an unfrozen refrigerator for winter, so it is planted in large pots. The Yangtze River basin can be wintered in the open air. The requirements for soil are not strict. But not drought-tolerant.

When is the northern okra planted?

Spring is fine.

Planting time of okra

In the Yangtze River valley and South China, okra can be planted in spring, summer and autumn, but mainly in spring. In the middle and lower reaches of the Yangtze River, it is suitable to sow in the open field after frost from late March to early April, and both hole sowing and drilling sowing can be used. If seedlings are raised in plastic greenhouses, they can also be carried out in early and middle March. When the seedlings grow to 4-5 true leaves, they can be planted. The planting time is from the end of April to the beginning of May. Sowing in March-April and harvesting in May-September; Sow in May-June, harvest in July-September, sow in July and harvest in September-165438+ 10.

Does anyone know okra? How to plant it? What month can I plant it?

Sowing and seedling raising

Live broadcast is the main method. Before sowing, the seeds were soaked in warm water at 20-25℃ for 65,438 02 hours, then dried and germinated at 25-30℃ for 48 hours. When the seeds are half exposed, you can sow. Dig pits according to the row spacing of 40 cm and the plant spacing of 12cm, water the soles of feet first, sow 2-3 seeds in each pit, and cover with soil for 2-3 cm.

Tiantuan management

(1) intercropping

When the heart is broken, it is the first thinning, and the weak seedlings are occasionally eliminated. When there are 2~3 true leaves, the second thinning should be carried out and the strong seedlings should be selected. 3~4 true leaves will become seedlings, with 1 plant per hole.

(2) intertillage weeding and ridging

After the seedlings are unearthed or planted, the temperature is low, so they should be cultivated twice in a row to raise the ground temperature and promote the slow seedling. Strengthening intertillage and squatting properly before the first flowering is beneficial to root development. After flowering and fruiting, the plants grow faster. After each watering and topdressing, the plants should be cultivated in intertillage before closing the ridge to prevent the plants from lodging. In rainy and windy areas in summer, it is best to use bamboo poles or branches around 1 m to prevent lodging.

(3) watering and fertilizing

① Watered okra needs high air and soil humidity during its growth. If there is water shortage within 20 days after sowing, artificial sprinkler irrigation should be carried out sooner or later. Mechanical sprinkler irrigation or furrow irrigation can be used after the seedlings are slightly larger. The hot summer is at the peak of okra harvest, with large water demand and high surface temperature. You should water before 9: 00 a.m. and after sunset in the afternoon, so as not to damage the roots by high temperature watering. Pay attention to drainage in rainy season to prevent seedling death. The whole growing period is to keep the soil moist.

(2) On the basis of applying sufficient base fertilizer, topdressing should be appropriate, and nitrogen fertilizer should not be applied in a partial way. The first time is full seedling fertilizer, which is carried out after emergence, and urea is applied 90~ 120 kg per hectare. The second time is seedling fertilizer. After seedling raising or planting, furrow is opened and application is withdrawn, and 225-300 kg of compound fertilizer is applied per hectare. Top dressing at flowering and fruiting stage, 30,000 ~ 45,000 kg of human excrement or 300~450 kg of NPK compound fertilizer. In the middle and late stage of growth, a small amount of topdressing should be divided into several times as appropriate to prevent premature senescence of plants.

(4) Factory supervision

Under normal circumstances, okra plants grow vigorously, with thick main branches and thick leaves, and flowering and fruiting are often delayed. Twisting branches can be used, that is, twisting the petiole into an arc to control vegetative growth. In the middle and late growth stage, removing the old leaves under the harvested young fruits in time can not only improve the ventilation and light transmission conditions, reduce nutrient consumption, but also prevent the spread of pests and diseases. Picking tender fruits at the right time can promote the fruiting of lateral branches and increase the early yield.

Can okra be planted all year round?

No, it's not a plant that can be planted all year round. It doesn't pod at low temperature.

Okra likes warmth, is afraid of cold and has strong heat resistance. Stop growing below 8℃. When the air temperature is 65438 03℃ and the ground temperature is about 65438 05℃, the seeds can germinate. But the optimum temperature for seed germination and growth period is 25~30℃. The monthly average temperature is lower than 17℃, which affects flowering and fruiting; When the night temperature is lower than 14℃, the growth is slow, the plants are short, the leaves are narrow, the flowers are few and the flowers are many. At 26~28℃, there are many flowers, high fruit setting rate, rapid fruit development, high yield and good quality.
