Okra, also known as Bushencao, okra and croissants, is a Malvaceae, an annual herb. Okra is mainly eaten with tender fruit and has the effect of strengthening stomach and intestines. It is an ideal high-grade green nutrient health vegetable in the new century. Okra is adaptable, grows vigorously, and has few pests and diseases. It is easy and easy to grow Okra. It has the advantages of less man-hours, fewer species, low cost, and high benefits. The output of mu is 1500-2000kg, and the output value is up to RMB9000-12000 according to the selling price of RMB 6/kg. The economic benefit is very considerable. 1 Preparation before broadcast Okra is hi light, drought-tolerant and frightened, and should be planted in a place with high topography, convenient irrigation and drainage, deep soil and loose and fertile land. After deep plowing, 667-2000kg of composted organic fertilizer, 30-40kg of compound fertilizer, and 20-25kg of tea seed cake are applied per 667m2 (tea seed cake can effectively prevent underground pests, and it is a good organic fertilizer after maturity), and then it can be used for digging. It is 1.2m wide, 25-30cm high, and 30cm wide. Each row of 2 rows, spacing 50cm. 2 Sowing seedlings The optimum development temperature of Okra is 25-30°C during the day and 18-25°C at night. In the Yangtze River valley, okra can be cultivated in spring, summer and autumn, but it is mainly spring sowing. Sowing in March-April, harvesting in May-September, sowing in May-June, harvesting in July-October, sowing in July and harvesting in September-November. The early sowing should adopt the greenhouse, the small arch shed or the mulching film to cover the cultivation, the summer mainly uses the open cultivation. Live broadcasts can be used, but seedlings are better for seedlings. Before sowing, soak in 15 minutes with warm soup at 55°C, soak for 24-48 hours after cooling, and sow until half of the seeds are white. 2-3 seeds per hole during live broadcasting, 667 m2 seed amount about 400-500g, about 2cm cover soil after sowing, keep the soil moist, when the seedlings 2 true leaves and time seedlings, 4-5 true leaves when the seedlings, each hole Keep a strong seedling. 3 Field Management Fertilizer management. After planting, apply 5 times compound fertilizer solution once a week to strengthen the seedlings. Around 50 days after sowing, the plant height reached about 50cm and entered the flowering stage. Combined with cultivating soil, 10kg of compound fertilizer was applied per 667m2. In the full fruit period, fertilize 1 time every 10 days, and apply 10kg of compound fertilizer per 667m2. In the late growth stage, 0.3% potassium dihydrogen phosphate solution is sprayed on the leaves to prevent premature aging. Moisture management to keep the soil moist prevail, usually 7-10 days, 1 water, summer heat season to maintain good water supply, rainy days should be done in time to clear the gutter drainage work to prevent water rot. Plant management. Okra dominated by the main vine, the side branch, the old leaves in time to remove, reduce nutrient consumption. During the growth period, in order to prevent the wind from falling or even breaking, it is necessary to reinforce the bamboo raft with a length of 1m and a diameter of 2cm per acre to ensure erect growth. 4 Pest control Okra is very susceptible to viral disease in the later period. On the basis of the elimination of aphids and other pests, it can be sprayed 1000 times liquid of lentinan to improve its resistance to disease. Okra insects are less pests, mainly Spodoptera litura and aphids, the prevention and treatment of Spodoptera litura can be used 1000 times chlorantraniliprole spray, aphids can be used 10% osmium 2000 times spray. 5 Timely harvest When the fruit grows to a length of 8-10 cm 5-7 days after flowering, it can be harvested and marketed. Cut at the stalks during harvesting to avoid damaging the branches and fruits. At the same time, the fruits, branches and leaves of Okra have bristles and damage the skin. So daily management and harvesting must wear long-sleeved clothes and gloves.
