Sowing and Seedling-raising techniques of okra

Sowing technology

Okra is suitable to be planted on land with deep, loose and fertile soil. Apply sufficient base fertilizer at the same time for soil preparation. Generally, 2000 kg of soil and miscellaneous dung and 100kg of cake fertilizer are applied per mu. Seedlings are usually sown in sunny beds or solar greenhouses from the end of March to the middle of April. The seedbed soil was prepared at 6:3:1 according to the proportion of vegetable garden soil, rotten organic fertilizer and fine sand, and was sown at a density of 10 cm square. Because the seed shell of okra is hard, the seeds should be soaked for 24 hours before sowing, then germinated under 25 ℃ 30 min, and germinated in 5 days. The seedling age is 30-40 days, that is, the seedlings should be planted at 3 Mel and 4 leaves. Direct seeding is usually sown from the first ten days of April to the first and middle of May, and the beds are made according to the width of 1 meter, with two rows per row, with a density of 50 cm, and 2 Murray and 3 seeds per hole. The cultivation with plastic film mulching can sow 4m / m early for 6 days. When the seedlings grow out of two leaves, there is only one strong seedling in each hole, and the seedlings are fixed when the leaves are 4 / 4 / 5.
