What kind of plant is this,

Okra, plant name. Also known as okra clip and croissant, it is panicum miliaceum of Malvaceae, which originated in Africa and later entered America. Now the largest okra producing area is in the southern United States, and Americans have given it a more memorable name-"Plant Viagra".

Other aliases: kidney-tonifying vegetables, croissants, foreign peppers and Huang Kui coffee.

Most men eat it, hehe. It is said that it can tonify the kidney and strengthen the body, hehe.

Open field cultivation techniques 1. In the cultivation season, okra likes warmth and is afraid of frost. The whole growth period should be arranged in the frost-free period, and the flowering and fruiting period should be in the 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. Intensive seedling raising in solar greenhouse and plastic shed is often used in cold areas in the north, and then planted in the field after early spring and late frost [1]. 2. Land preparation of border okra should not be continuous cropping, nor should it be continuous cropping with fruits and vegetables to avoid root-knot nematodes. It is best to choose root vegetables and leafy vegetables as previous crops. Loam with deep soil layer, fertile and loose soil layer and water and fertilizer conservation is more suitable. In winter and after the harvest of previous crops, it is necessary to plough deeply in time, remove 75,000 kilograms of decomposed manure and 300 kilograms of NPK compound fertilizer per hectare, and evenly mix and harrow the ridges. Cultivation methods in open field: row spacing 40cm, plant spacing 12cm, and ditch width 50cm. If the plants are planted in a single row at the edge of fields, roadsides and rivers, the spacing between plants is 12 cm, and there are 3 plants in each hole, which is well ventilated and easy to manage. 3. Sowing and direct seeding are the main methods. 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 40cm and the plant spacing of 12cm, water the soles of feet first, sow 2-3 seeds in each pit, and cover 2 seeds with soil. (1) live broadcast mode

Okra multi-line live broadcast. Soak the seeds for 12 hours before sowing, and then put them at 25 ~ 30℃ to accelerate germination. Seeds begin to germinate in about 24 hours, and 60% ~ 70% seeds are sown when they break. It is advisable to sow in holes, with 3 plants per hole and a hole depth of 2 ~ 3 cm. All localities should sow in time after the final frost period, first water, then sow, and then cover the soil for about 2 cm. (2) Seedling-raising and transplanting method Seeding and seedling-raising were carried out in sunny beds and solar greenhouses in northern China more than in the first half of March. The bed soil is formed by mixing 6 parts of garden soil, 3 parts of decomposed organic fertilizer and 1 part of fine sand. Soak seeds before sowing to accelerate germination, level the seedbed, and sow at the row spacing of 10 cm, with the covering thickness of about 2 cm. After sowing, the temperature of bed soil should be kept at 25℃, and it will germinate after 4 ~ 5 days. Seedling age is 30-40 days. Sow when the seedling grows to 2-3 true leaves. It is best to use plastic pots, nutrient clods and other measures to protect roots and raise seedlings, and cultivate healthy seedlings of appropriate age. [3] 4. When thinning is interrupted in field management (1), it is the first thinning, and weak seedlings are 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) After the weeding and ridging seedlings are unearthed or planted, the temperature is low, so it should be cultivated twice continuously to increase the ground temperature and promote the slow growth of seedlings. 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) Water and fertilizer ① Water okra needs high air and soil humidity during its growing period. 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. 5. It takes about 55 days to harvest the okra from sowing to the formation of the first tender fruit. In the future, the whole harvest period will be 90 ~ 120 days, and the whole growth period will be about 150 days, or even longer. The picking standard of commercial fresh fruit of okra is that the fruit length is 8 ~ 10 cm, the fruit surface is bright green, and the seeds in the fruit are not aging. If the harvest is not timely, the meat will age, the fiber will increase, and the edible value of the goods will be greatly reduced. Generally, after the first fruit harvest, it is harvested every 2 ~ 4 days in the early stage, and the harvesting interval is shortened with the increase of temperature. In the fruit-rich season in August, harvest once a day or every other day. After September, the temperature drops, and the crops are harvested every 3-4 days. Use scissors and gloves when harvesting to prevent bristles or thorns on stems, leaves and fruits from stabbing the skin and causing unbearable itching. At this time, washing with soap or baking lightly on the fire can reduce the degree of itching. Usually, the tender fruits are harvested 4 days after the flowers wither, and the quality is the best. The yield per mu is about 2000 ~ 3000 Jin.
