Okra is also known as okra and crocus. It is a one-year or perennial herb of the family Okra, native to Africa. Okra is served with tender Fruit and contains more protein, vitamins and mineral salts. The high-yielding cultivation techniques are now described as follows:
First, soil fertigation
Prepare the okra plantation plot. After harvesting the okra, it is necessary to perform deep plowing in autumn and winter in time and deep plowing for 30 cm to deepen the mature soil layer to further loosen the soil and enhance the soil's ability to store water and fertility. Before planting, the land is made fine, flat, loose and soft, and it is put on the ground. Okra requires more fertilizer, spread 5,000 kg per acre of manure, 20 kg of compound fertilizer, spread to the ground before the site preparation, and then deep into the soil, mix thoroughly, so that the soil fertilizer mix, and then do a ditch. Avoid continuous cropping, and vegetables and vegetables should not be selected for the former.
Second, the appropriate sowing
More use of live broadcast method can also be transplanted seedlings. It is sown in mid-May, planted in mid-June, and harvested in August.
Third, fine sowing
Okra seed coat hard, sowing 12 hours after soaking should be placed under conditions of 25 °C germination, to be 60% to 70% of the seeds "broken" when sowing. Seeding is suitable for on-demand broadcasting, with a width of 85 cm and a width of 30 cm. Each row is one row with a 30 to 35 cm hole spacing. Each hole is sown with 2 to 4 seeds and the depth of the hole is 2 to 3 cm. First water, then sowing, and then cover the earth about 2 cm thick. The use of nutrients and plug seedlings, sowing 2 seeds per hole, 2 to 3 true leaves when Dingmiao.
IV. Seedling cultivators
Okra after emergence and time seedlings, 2 to 3 true leaves, remove disease, weak, seedlings, leaving 2 per hole. After the seedlings have been unearthed, they should be cultivated and weeded in time, once every 10 days or so. The first flower should be strengthened before the opening of the cultivator, appropriate seedlings to promote root development. After the flowering results, the growth of plants was accelerated, and cultivators should be used after each top dressing and watering. Soil cultivating before mulching to prevent plant lodging. From July to August, when it enters the high-temperature rainy season, weeds breed rapidly and weeds should be removed in time to prevent grass shortages.
Fifth, fertilizer management
Okra is more tolerant to drought and moisture, requires higher air and soil moisture during growth, and especially requires sufficient moisture during flowering. Okra grows for a long period of harvest and lasts for about 100 days. In the base fertilizer application based on proper top dressing, the first top dressing after emergence, urea per acre 6 ~ 7 kg; the second Shimiao Miao, after the fixed seedlings after the application of 15-20 kg compound fertilizer; flowering As a result, a heavy fertilizer was applied and 25-30 kg of compound fertilizer was applied. After entering the fruit-picking period, according to the growing trend, apply topdressing several times, as appropriate, to prevent lodging or premature aging. In summer, the okra harvest time is high, the water requirement is large, and the surface temperature is high. It should be watered before 9:00 AM or in the afternoon after sunset to avoid watering and rooting at high temperatures. Pay attention to drainage in the rainy season to prevent dead seedlings.
Six, set off the leaves
In the summer, a stand should be placed to prevent lodging, and a bamboo or tree branch with a length of 1 meter can be used to support the plant. In the early growth period, it is necessary to prevent nutrient overgrowth from causing excessive growth. In the middle and late stages, the old leaves below the harvested tender fruits are removed in time, which can improve the ventilation and light transmission conditions, reduce nutrient consumption, and reduce the occurrence of pests and diseases. Fruits should be picked up in time to promote the seeds, can promote the mature fruit, in order to facilitate the full grain, improve seed quality.
Seven, control pests
Okra has fewer diseases and more pests. There are mainly locusts, thrips, virus diseases, and so on. Each can use 10% Furosemide granules 1000 to 1500 mg per mu. After the growth period, if there is insect infestation, 50% phoxim EC, avermectin, herbicide, etc. can be sprayed and sprayed every 5 to 7 days.
