The efficacy and function of okra the planting method of okra

Nutritional value of okra

The main results are as follows: 1. Okra tender pods are rich in pectin and dietary fiber, and the sticky state of pectin is very rare in the plant world. the proportion of dietary fiber and soluble dietary fiber is very high in plants.

2. Okra tender pods are rich in vitamin A, carotene, vitamin C, E and so on, especially the content of vitamin An and carotene ranks first in all animals and plants found at present.

3. Okra tender pods also contain selenium, calcium, iron, phosphorus, potassium and other trace elements, but the content is not particularly rich.

The efficacy and function of okra

[taste] bitter taste, cold nature.

Kidney, stomach and bladder meridian.

[efficacy] strengthening yang, tonifying the kidney, ventilation, clearing heat and promoting dampness, suitable for gastritis, cancer, gastric ulcer, anemia, dyspepsia and other diseases.

1, aid digestion: the sticky substance of okra can promote gastrointestinal peristalsis, help digestion, benefit intestines and stomach, and improve hypoxia tolerance.

2. Protect the liver: the pectin of okra, the polysaccharide has the effect of protecting the liver.

3. Cancer prevention: 50% cellulose in the sticky substance of okra is good for cancer prevention.

4. Supplement calcium to lose weight: okra not only has the same calcium content as fresh milk, but also has a calcium absorption rate of 50-60%, which is 1 times higher than that of milk, so it is an ideal source of calcium. At the same time, okra is a low-energy food, which is a good food to lose weight.

5, kidney-tonifying effect: okra is also known as sheep's horn bean, Americans call it "plant Viagra", you can see its kidney-tonifying effect. Okra for young adults and athletes, regular consumption, can eliminate fatigue, quickly restore physical strength, of course, this has this effect on all people.

Planting methods of okra

1. Planting time: okra is cultivated in the open field, sown in April-June in north and south, and harvested in July-October. The seeds in North China are usually sown from mid-late April to May. Seedlings are raised in solar greenhouses and plastic greenhouses commonly used in cold areas in the north, and then planted in the field after frost in early spring and evening.

2. Soil preparation and fertilization: the plot of okra is prepared to be planted. After the previous harvest, deep ploughing in autumn and winter should be carried out in time, with a depth of 30 cm, in order to deepen the ripe soil layer, further loosen the soil, and enhance the soil water storage and fertilizer conservation capacity. Make the land fine, flat, loose, soft, empty and solid before planting. Okra needs more fertilizer, spread 5000 kg of rotten barnyard manure and 20 kg of compound fertilizer per mu, spread it on the ground in front of soil preparation, then turn deeply into the soil, mix well with fine rake, mix the soil and fertilizer, and then open a ditch to make the border.

3. Interseedling ploughing: it is necessary to have time seedlings after emergence of okra seedlings. When there are 2 or 3 true leaves, get rid of diseased, weak and small seedlings, and leave 2 plants in each hole. After the seedlings are unearthed, they should be ploughed and weeded in time, once every 10 days or so. Before the first flower blossoms, we should strengthen ploughing and squat seedlings properly to promote root development. Cultivate the soil before closing ridges to prevent plant lodging.

4. Fertilizer and water management and protection: okra is more resistant to drought and moisture, and requires higher air and soil moisture during the growth period, especially in the flowering and fruiting period. Okra has a long harvest time, and the whole growth period is about 100 days. On the basis of adequate base fertilizer, the first topdressing was carried out after seedling emergence, applying 6kg urea per mu.

5. Set up a frame to pick leaves: in summer, a support should be set up to prevent lodging. A 1-meter-long bamboo pole or branch can be inserted next to the root of the plant to support the plant. In the early stage of growth, the overgrowth of vegetative growth should be prevented, and the old leaves below the tender fruit should be removed in time in the middle and later stage. Those who are reserved for planting fruit should pick the heart in time, which can promote the ripening of the fruit, make the grain full and improve the seed quality.

6. timely harvest: okra blossoms and bears pods from sowing to plant height of about 30 cm and true leaves of 7-9, and it takes about 60 days for the first tender fruit to form. After that, the whole harvest period is as long as 60-100 days, and the whole growth period can reach about 120 days, or even longer.

7. Seed storage: the seed collection technology of okra is relatively simple. When it enters the growth period, vegetative growth and reproductive growth go hand in hand. In order to avoid restraining growth and reducing yield, the lower fruit in the early stage should not be used as seed, the pod at the top of the plant is difficult to fully mature, even if it is fully mature, the grain is not full, the quality is poor, and it is not suitable to leave seeds. Therefore, it is appropriate to keep the mature pods in the middle of the robust plant with full grains (the shell of the fruit turns yellowish brown and cracks appear). After drying, threshing and cleaning, it is stored in the cloth bag.
