Choose the right time to plant with the plot:
Okra likes to grow warm, the most afraid of frost, so the whole growth period should be arranged in the frost-free period, flowering and fruiting period should be in the warm and humid season. Open field cultivation, the south more in march-may sowing, may-november harvest. In North China, the sowing date is from late April to June, and in Chengdu, the sowing date is from April to June. Okra resistance to dry, wet, but not bubble, choose the site should be easy irrigation and drainage, convenient for the premise. Okra has a strong adaptability to soil, but deep soil and loose soil are better, especially for sandy soil with strong water retention capacity. Okra likes fat and likes water but not waterlogging.
Seedling and establishment:
Seed can be soaked 1-2 days before sowing, in order to advance the emergence time. If the direct seeding then each hole sows 2-3, each MU uses the seed quantity approximately 300-500 grams. If seedling transplanting to do a good job first seedbed, seed direct broadcast sowing, to the seedling leaves grow to 3-4 when planted.
To make furrows:
Okra has a strong adaptability to soil, especially in the deep soil layer with high organic matter content. Before sowing deep plowing furrow, furrow width of 1 meter, 20 cm wide, each furrow planting two rows, plant spacing 30 cm, mu planting 3000-3500 holes, a hole a plant or two can be, base fertilizer can be applied into 1500 kg of compost manure. Need to pay attention to okra is light crops, cultivation should not be too dense, light, well-ventilated areas can be a hole two plants to increase production.
Tillage, weeding and earthing:
The root system of OKRA is particularly developed. In order to promote the growth of its root system, it should be intertilled many times before the emergence of flower buds, and after each topdressing and irrigation after the emergence of buds, it should also be properly intertilled to prevent soil compaction. Combined with cultivation, weeds should be eliminated in time to avoid grass shortage. Earthening should be carried out before sealing the plant to prevent lodging during heavy wind and rain.
Water management:
Okra needs more nitrogen fertilizer in the early stage of growth, more phosphorus and potassium fertilizer in the middle and late stages, and it needs to be topdressed many times in the growth period. The first topdressing after planting seedlings (direct seeding in 4-5 leaves) , Mu 1000 kg manure, the second topdressing in the early fruit, mu 1500-2000 kg manure, after half a month topdressing. Every topdressing to add nitrogen fertilizer 5 kg per mu, from the second topdressing also, need to join the phosphorus, potassium fertilizer with the application. Topdressing combined with irrigation, heavy rain season to pay attention to drainage, to avoid waterlogging plants.
Plant preparation:
Master the principle of ventilation and light, in the plant branches and leaves too lush when the appropriate cutting off the base of the side branches and remove the old leaves. After picking the tender pod, remove the leaves under the pod, in order to facilitate the growth and development of the back of the tender pod.
