1 The selection of pots and the choice of place
Planting okra in the garden requires flowerpots with a diameter of 40 cm and a height of 50 cm or more. The wider the plant, the better the extension of the roots of the plants.
2 Soil selection
Choose a loam or sandy loam with good soil quality.
3 basin base fertilizer preparation
To make the plants grow well, basal fertilizer is very important. Before potting, chicken manure or silkworm sand or other livestock manure is fully heaped and decomposed, and 200 times of EM original dew or VT-1000 bacteria solution can be sprayed on the manure. Mix well to a moisture content of about 50%, just to catch water droplets. Compost time should be more than 15d.
4 Preparation of Potted Substrates
According to the ratio of 3:1, the soil and base fertilizer are mixed and put into a human flower pot, and the pot of mud is filled with 3/4, and a layer of soil with a thickness of 5 to 8 cm is laid on the upper layer. Spray 500 times more of the EM dilution solution. Allow the soil to wet and leave it as a reserve.
5 Sowing seedlings
5.1 sowing season
The south of the Yangtze River can be cultivated in the spring and summer, but it is mainly spring sowing. Spring sowing time is from March to April, and it can be harvested till the end of October.
5.2 Sowing
Okra seeds are often seeded, with 2 to 3 seeds per pot, and 34 cm of fine cover soil when planted. Okra seed coat is hard, soaking seeds must be sowed for 24h before sowing, cleaning and changing water once every 5-6h, such as germination under the environmental conditions of 25-30 °C, 3 ~ 4d can be sowed after budding, sowing about 10d can emerge .
6 seedlings planted
When okra seedlings were unearthed, they should be seedlings after time of emergence to remove weak seedlings and diseased seedlings. When the okra seedlings grow to 34 true leaves and the seedling height is 10 to 15 years, only one strong plant per pot remains, and the remaining ones are removed or transferred. To other pots grow poor pot cultivation. And give enough water to facilitate survival.
7 Field Management
7.1 Fertilizer Management
In addition to the foot basal fertilizer, the okra should also be top-dressed several times in the growing season.
7.2 weeding and earthing
After the okra seedlings are unearthed or planted, we must avoid seedlings and weeds from competing for water and timely weeding. Once every 7-10d. After the flowering results, the plant growth was accelerated. After each watering and top dressing, the soil was loosened with a spatula to prevent the plants from lodging. In the rainy days and windy areas in summer, it is best to use a bamboo raft of about 1m in length, and branches are inserted near the plants and tied with a string to form a “8†shape to prevent lodging.
7.3 Plant Adjustment
In the early growth period of okra plants, the lateral branches should be removed in time, which is beneficial to the early results of the main stem and increase the yield. In the early growth period, the nutrition growth is too prosperous, and the method of twisting the petiole can also be adopted to twist the petiole into a curved droop to control the vegetative growth. In the middle and late growth stages, the old leaves below the harvested young fruit are promptly removed to improve the ventilation. Translucent conditions, reduce nutrient consumption, but also prevent the spread of pests and diseases; harvesting fruit should be timely picking heart, can promote the mature fruit, in order to facilitate full grain, improve seed quality.
7.4 watering water
Okra is drought- and moisture-resistant, but not tolerant. During the germination period, the soil moisture is too large and it is easy to induce seedling blight. The results of the drought, the plant growth is poor, poor quality, should always keep the soil moist. Potted okra water dispersion, pay attention to observation, at least 1 day (preferably morning and evening can water), to prevent the basin soil drought. The summer season coincides with the harvest period of Okra. The soil surface temperature is high. It should be watered before 9:00 in the morning and after sunset in the afternoon to avoid watering and rooting at high temperatures.
7.5 Measures to promote flowers and fruits
When the okra grows 10 to 15cm in height, 200-300 times of the original EM is sprayed on the foliar, and then the water is sprayed 1 time before flowering, and then sprayed once every 10-15 days after harvesting 1 fruit. EM original exposed 200 times plus 0.1% potassium dihydrogen phosphate solution (both can be mixed spray). After such measures were taken, Okra bloomed many fruits, grew fruit, had many pulps, and its quality was sweet and soft, and the harvest period was prolonged, resulting in a large increase in yield.
7.6 Pest Control
Okra has fewer pests and diseases, and occasionally locusts, aphids, ants, and ground tigers harm it. The garden is planted with okra. It is advisable to use trap-type insecticidal lamps and yellow plates to trap adult insects. If it is found to be a locust infestation, kill it manually. It can be controlled by spraying 50% anti-influx or 2000 times by 2000 times. For control of the ground tiger, 90% trichlorfon 500 times solution can be filled around the rhizosphere to poison the larvae. During the rainy season, more lesions appear on branches and leaves, and lime can be sprayed near the base of the plants in time after the weather turns fine to prevent the spread of diseases.
8 timely harvest
Okra from the 4th to the 8th section began to flowering results, in the appropriate temperature conditions, flower after Xie 2-4d can harvest the tender fruit, the general tender fruit grow to 10-15cm long, about 25g can be harvested. Early harvesting is low, harvesting is too late and fibrosis, quality is reduced, and unfit for human consumption. Harvesting usually takes 2 to 3 days before harvest, 1 harvest, and 3 to 4 days in the middle and late harvests. Harvesting should be carried out in the morning or in the evening, and cut at the stalk to prevent damage to the branches. There are bristles or thorns on the stems, leaves and fruits of Okra. Wear gloves when harvesting, otherwise the skin will be stabbed and unbearable.
