Okra is a vegetable for the consumption of tender fruit, alias okra, croissants and so on. The open cultivation can be carried out in the spring, summer and autumn seasons. From the beginning of April to the end of November, there can be a continuous supply of fresh pods. The high price and high profits of okra can bring great wealth to the vegetable farmers. The following microbial fertilizer expert Jinbao introduced several techniques for the cultivation of okra.
1. Variety selection
Okra can be classified into plant height and dwarf variety according to plant height. It is advisable to choose high-cultivated and pod-shaped cultivars in southern Guangxi (such as New Tokyo 5). It has the advantages of drought resistance, heat resistance, strong disease resistance, strong green fruit, thick inner quality, excellent quality and long harvesting time. Dwarf varieties can also be planted, which has the advantages of suitable planting, lodging and management convenience, but in the product
Quality and yield are slightly worse than those of high plant varieties.
2. Selection of land and fertilization
Okra is adaptable and does not require high soil. However, in order to obtain high quality and high yield, it is better to choose a plot with high organic matter content, loose fertility, convenient drainage and irrigation, and sufficient sunlight. Avoid continuous cropping, it is also not suitable for continuous cropping of cucurbitaceae, solanaceous vegetables in order to reduce the damage of root-knot nematodes. Rotation with cruciferous leafy vegetables is better. Application of fermented edible fungus slag 2.5 to 3 tons, biogas slag 2500 to 3000 kg, compound fertilizer 30 to 50 kg, potassium fertilizer 10 to 15 kg, or 1 to 1.5 tons of rotten farmyard fertilizer per mu, 30 to 40 kg of compound fertilizer, and 10 to 15 kg of potassium fertilizer . The farmyard fertilizer should be decomposed. We recommend that the majority of vegetable growers use commercially available organic fertilizers such as Dendrobium organic fertilizers to produce organic fertilizers. Such organic fertilizers do not easily produce burned seedlings, and the inside bacteria contribute to the further utilization of fertilizers in the later period of plant growth. Distribute evenly in the first half months of planting and use a rotary tiller to dig into the soil and then level the land. Good pre-planting, 20cm high, 110cm wide, and 30cm wide.
3. Okra colonization
Okra is too cold to be cold and frosty. The planting in the open season in spring is appropriate. It is advisable to raise the seedlings in advance in the greenhouse to plant in the middle and late March. In April-June, the temperature is conducive to the growth and blooming of okra. Therefore, the seedlings should be timely transplanted to Daejeon when the temperature is stable above 17°C. Proper early planting is one of the keys to winning high and stable production. In the loft of 20cm in height, 110cm in width, and 30cm in width, planting lines (45-50cm) × 70cm are used for planting in double lines and acreage is planted in 2000 to 2500 lines. After planting, it is dripping with water. It should not be planted too deep in the spring. Deep planting temperature is low, hair roots are slow, and plant growth is slow. Planting in the spring should be conducted in sunny afternoons. It is advisable to select cloudy days for summer cultivation and planting. Okra requires sufficient light and close planting. If planted too densely, the leaves will overlap and shade each other during the middle and late growth stages. The plants will grow thin and thin, and the internodes will be long, which will be detrimental to the flowering results and will be prone to lodging, leading to premature aging. The moderately fertile plots of land are suitable for about 2000-2500 plants per acre.
4. Okra cultivator management
After planting, we must pay attention to frequent weeding and loose soil. When loose soil is generally 5 ~ 7cm depth is appropriate. The cultivator should be carried out before the plant grows to about 45cm in height (ie before budding). Soil and fertilizer are applied at the same time. After weeding, weeds are removed without cultivating tillage to prevent damage to the roots and plants. We must remove lateral branches in time to improve ventilation and light transmission in the fields and enhance photosynthesis. The main branch up to 80 ~ 100cm or so can pick up the heart, so that the nutrient concentrated supply of flowering results.
5. Okra picking
Okra is the result of continuous flowering crops. It is harvested once every 2 to 3 days and harvested once every other day, and once every 3 to 4 days in the later period. It is necessary to harvest timely when the berries are green, otherwise the fibers will increase, affect the eating quality, and affect the further flowering results of the plants.
